INSULIN AND CHRONIC DISEASE

dia 0116 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.Insulin: Its Crucial Role in Chronic Illness Ron Rosedale, M. D. 25th Inaugural congress meeting in Chicago.  A medical doctors conference pertaining to new  advancements in medicine.  This is likely the first talk that really discussed the role that Insulin plays in chronic illness.  Part One of Two

SPEAKER UNKNOWN: It is my extreme pleasure to introduce to you, Dr. Ron Rosedale, who will speak on INSULIN AND ITS CRUCIAL ROLE IN CHRONIC ILLNESS. Dr. Rosedale is associated with our President-Elect, Dr. John Wilson, and he will have some things to say that I believe will open our eyes. Thank you.

Dr. Ron Rosedale: Thank you for the privilege of speaking. The reason actually that I am speaking is that John asked me to, after the last AAEM meeting, and a very prominent speaker lectured on merits of a high carbohydrate diet. At the end of the talk, during the question-answer period, John got up, asked a reasonable question, “What about insulin?” The lecturer, who has written multiple books, basically just derided John, and said that he just hadn’t been keeping up the with the literature. This started a little bit of a heated discussion that went back and forth, and John knew of my interest in insulin for a long time.

First, let’s just take a look at what the literature has to say. First, we have to turn on the slide.

So, what about insulin?

dia 0008 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.

A carbohydrate diet is currently the diet of choice by the American Heart Association, The American Diabetes Association, The American Cancer Association, most weight loss experts, most nutritionists, and also, I should say, most sports physiologists. Carbo-loading is almost gospel in sports.

Let’s talk a little bit about hyperinsulinemia, because a high carbohydrate diet certainly causes high insulin levels. Hyperinsulinemia adversely affects almost all degenerative diseases. That includes coronary artery disease, hypertension, cancer, stroke, diabetes, of course, obesity, autoimmune disorders, and mental disease and decline. In fact, I think you’ll come to know, and it is not just my opinion, that it may be the chemical mediator of all of the degenerative diseases of aging. It may be the leading killer in our society. We are going to discuss what it is, what cause it, and why.

First, let’s just look back at other populations.

dia 0013 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.They have already tried a number of different diets; let’s see what happened to them. Going way back let’s talk about agriculturalist, and hunter/gatherers. Anthropologists can almost immediately identify a particular society of people when they do diggings, and dig up a bunch of bones. They know almost immediately whether that society was considered a hunter/gatherer, or whether they were considered agriculturalists. Agriculturalists grew grains, and they grew their food, where the hunter/gatherers lived mostly on meat. The bones, if they are nice and strong, and long, and if the teeth are in very good repair, and if the skeletons generally showed a large body-build, those are almost uniformly hunter/gatherers. The agriculturalists have much shorter bones, and their bones are much weaker. So, the assumption, and generally being very correct, is that the hunter/gatherers were the much healthier of the people.

Let’s talk about the Egyptian diet. Now, the Egyptians are kind of unique, in that they left an excellent record. There are considered to be more mummies than there are currently Egyptians, and many of these were preserved very well. Mummifying was probably the ultimate antioxidant. What did they eat? There are multiple records in the papyrus writings, and in the examinations of the digestive systems of the Egyptians were very excellent documentations of the diets of the ancient Egyptians. What was it? Well, they ate a lot of fresh vegetables. They ate a lot of lettuce, cucumbers, garlic, onion, lentils, peas, and they used a lot of olive oil. The only oils they essentially used for cooking were olive oil and sesame oil. They used no lard. They ate a lot of bread, and the bread was made by freshly stone-grinding wheat and barley. There were no processed foods; they didn’t have cans then. They used a little bit of honey, and no refined sugar; obviously, they didn’t have refined sugar then; that didn’t come for another thousand years. They ate no red meat. They ate a little bit of fish, they ate some chicken, and of course, it was free-range chicken. They ate a very low-cholesterol diet, and a very low-saturated fat diet. Does this diet sound familiar? Sounds like a diet that was previously recommended in this mornings talk as being a very excellent and healthy diet. I mean, you couldn’t go into a health food store and buy that good a diet.

dia 0011 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.So, what was the health of these people like? Well, a gentleman by the name of Iden Cogburn, who is the founder of the Paleopathology Association (this is a group of pathologists and other physicians who are very interested in studying scientifically the remains of ancient societies), wrote a book called MUMMIES, DISEASE, AND ANCIENT CULTURES. I’d like to quote him: “Atheromatous disease of the arteries is a common finding in mummies. Nowadays, a great deal of emphasis is placed on the stress of modern life. Once modern diet is factored in the high incidence of this disorder in our present-day industrialized civilization, but the etiological influences were certainly there in the ancient world, and this thought should be taken into account in any theorizing regarding causation.” It is well known that ancient Egyptians had a very high incidence of coronary disease. In analyzing the arteries, and they had a high incidence of calcified plaque in the arteries, and these people did not live long. They died young; even at a young age, their plaque was highly calcified, indicating it had been there for a while. We also know that they had hypertension, and they had rampant obesity. These people were not thin like you see in writings. Now of course, when we take pictures in magazines, we only take pictures of beautiful, live models. The ancient Egyptians were actually an obese society. They also had very poor dental hygiene. They had a lot of infection, a lot of parasites, and they were not a healthy society, and yet, they ate a diet that would be the choice of diet that is currently recommended. The diet that the Egyptians ate, and the diet that is currently recommended, is a high-carbohydrate diet. Now, their diet was a very high complex carbohydrate diet; there was nothing refined at all about it, yet they were not very healthy. This is uniformly found in ancient cultures.

I would also like to take a look at the Eskimos. The Eskimos eat a diet that for most people would be considered horrendous. Anywhere between 70 to 90% of the calories derived in Eskimo diets are from fat, depending on the season. Sometimes they will eat a high-protein diet, high protein or fat. They eat very little carbohydrates. In wintertime, they eat no carbohydrates. Coronary disease is almost unknown; so is diabetes. Look it up!

dia 0012 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.In the last, well, especially 15 years, but even 20 or 30 years, our consumption of fat has declined. You cannot go into a grocery store anymore without seeing row after row of nonfat foods. We’ve got nonfat Fig Newtons, nonfat cheese cake, and nonfat everything – fat has gone down, I mean, Snackwell’s from Nabisco is one of the hottest companies, nonfat cookies. What’s happening to us? In a very short period of time, in the last 12 years, the incidence of clinical obesity, which is considered 20% over ideal weight by the Metropolitan Life Insurance tables, has gone from 25% to 33%. We’re the fattest country on earth. So, if the fat consumption has gone down, our fat has gone up. We are substituting the fat calories for carbohydrate calories.

Well, let’s talk about insulin.

dia 0014 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.Insulin really is the master hormone of metabolism. It tells our energy where to go, and what to do, and how to do it. It regulates our energy intake. When you’re talking about obesity, and when you’re talking about anything that has to do with fat, or coronary disease, you cannot ignore insulin. It’s there to tell that fat where to go, and how to get there. Of course, we know it is made in the pancreas, in the beta cells of the islet cells of the pancreas, it is initially stored as granules, and those granules are released when there is a sensation of blood sugar, and that quick release is lost in type II diabetes. I’ll kind of breeze over this; I don’t want to dwell too much on some of this. One thing I do want to mention is, in the molecule itself, there is a small peptide called C-peptide, and that C-peptide is cleaved when it is released into the blood stream. You can use that little peptide to determine how much insulin a pancreas is putting out. So, if you have a patient who is on insulin, how can you tell if their own pancreas is working? How much insulin are they actually manufacturing themselves, without getting poisoned by exogenous insulin? Well, you can measure the C-peptide level, and you can know whether they are producing their own insulin or not. That is a very important test, because that is going to tell you ultimately whether that person really needs to be on insulin or not.

Let’s look at the evolutionary role of insulin.

dia 0015 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.Why is insulin really there? You talk about insulin, and you think about decreasing blood sugar, and insulin is there to lower blood sugar. I wasn’t around at the time, but I don’t think that was really the reason that insulin came about. I mean, insulin really came about to manufacture, and to regulate energy. Way back when, I don’t think lowering blood sugar was a major problem; there wasn’t that much of it. There wasn’t much carbohydrate out there; nobody had sugar. Nobody ate Twinkies. We have one hormone to lower blood sugar – that’s insulin. We’ve got a bunch of them to raise blood sugar. I maintain that it was actually increasing blood sugar that was our main problem. Our brain burns glucose. There are a few tissues in our body that actually prefer to burn sugar; that’s our RBC’s, our retinas, and certain tissues in our gonads. The rest of the body would prefer to burn fat, but it is due to the tissue’s requiring glucose that we need to maintain a certain level of blood sugar, and so we have developed multiple hormones to keep the sugar up, if we are not taking in very much carbohydratewhich, millions of years ago, just wasn’t there.

Let’s talk quickly about glucose homeostasis. You eat sugar, you eat carbohydrates, cause an increase in blood sugar, at least to the release of insulin from the pancreas, and the production of the insulin in the pancreas, which is important. That goes right to the liver, which shuts off hepatic gluconeogenesis. That is a very important concept. One of the main effects of insulin is to turn off the liver’s production of glucose, and we will get to that a little bit later, too.

 

dia 0020 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.The sugar goes to the receptors throughout the body, especially fat and muscle cells, and that stimulates the number of reactions which cause glucose uptake and utilization, glycogen synthesis, and then decreased serum glucose, straight forward. Now, what happens when you have a high-carbohydrate meal? That causes the output of quite a bit of insulin. This causes a lot of large numbers – large numbers, large mistakes. You eat a bunch of carbohydrates, this forms a bunch of blood sugar, and your pancreas senses that you’ve got a very high blood sugar level, so it just dumps all those insulin granules, to try and get that blood sugar stored. That can cause generally an overshoot, and the sugar goes a bit too low. Now, what happens? Your body puts out the multitude of regulatory hormones to increase blood sugar that has evolved over the years, many years ago. Glucagon, and in particular cortisone, epinephrine, and growth hormone, to some extent. That is a frequent cause of stress. It’s probably your main stress: the constant stress on the adrenal to produce cortisone to raise your blood sugar after it has gone too high, and then too low. It goes up and down and up and down, and it’s a constant cycle that we are going through all day long. It has multiple repercussions. In addition, we still have quite a bit of insulin out there. Now, that insulin is turning off the production of sugar, and it signals the brain when that sugar is low, to crave sugar and carbohydrates. When your levels drop, one of the main effects is that you crave carbohydrates to get that sugar back up. This is one of the main causes of sugar craving. What happens, you’ll go for that nearest bag of potato chips you can. What happens? Blood sugars go way up again, and we repeat the cycle, day in and day out, week after week, year after year.

Glucagon – you don’t hear much about Glucagon. Glucagon is also manufactured in the pancreas, right next to where insulin is manufactured, in the alpha cells. This essentially has the opposite effect of insulin. It stimulates the burning effect, it stimulates the breakdown of glycogen to increase blood sugar, it stimulates gluconeogenesis, the manufacturer of sugar from amino acids, and it increases your blood sugar, and it is secreted in response to eating proteins, and not carbohydrates. You never hear of alpha cell burn out. Beta cell burn out is common, as it is happening to all of us. You never hear about alpha cell burn out. Why is that?

Okay, let’s talk a little about insulin physiology.

dia 0023 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.What does it do? You talk insulin, you could talk to an endocrinologist. “What does insulin do?” “It lowers your blood sugar.” Yeah, but you’ll see, it does a lot more. It increases fat storage and uptake through an enzyme called lipoprotein lipase. A ton of research right now is going on lipoprotein lipase; insulin turns it on. You cannot get fat without it. Lipoprotein lipase allows fatty acids to get into cells. Basically, what it does, is it takes the fatty acids from triglycerides. Triglycerides themselves cannot get right into a fat cell. It has to be broken down into fatty acids. The fatty acids then enter the adipose tissue, and then turn into fat. Lipoprotein lipase is turned on, and you get fat. It is a very important enzyme.

Insulin decreases gluconeogenesis in the liver. That is really, in a 24-hour period, how insulin lowers your blood sugar, not so much by transporting into cells. Your total amount of blood sugar in a 24-hour period is increased more by gluconeogenesis in the liver than it is by your dietary intake. The regulation of gluconeogenesis by insulin is extremely important. We’ll get to that a little bit later. It increases the amino acids in the muscle tissue. Insulin is an anabolic hormone. It is a very powerful anabolic hormone! Growth hormone works very minimally without insulin. The two work together. Growth hormone and insulin allow different amino acids in the cells. Without both of them, you really cannot get a complete protein into your cells. Weight lifters are starting to recognize this, because insulin is not banned. It increases fat storage, especially visceral and abdominal, and that’s very important. That is where it packs the fat. We’ll talk about that in a little bit. I don’t know if you heard about the apple shape and the pear shape. Apple shape is much more detrimental to your health, especially in women. That’s where you get fat belies. You get fat thighs, and you might not look so great, but you’re not hurting your health as much. Insulin puts it in your belly, packs it in your liver, packs it in your kidneys, and inhibits function.

dia 0024 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.Another very important aspect; insulin decreases fat lipolysis. You cannot burn fat when insulin levels are high. It is very difficult. You try to go on a diet, and you have high insulin levels, you might lose weight, but you’re not going to burn fat. You’ll burn everything else that can turn to sugar, that could include your heart, first. You lose lean body tissue. You get increased saturated fat production delivered from sugar. Insulin tells your liver to make fat from your excess sugar floating around that you’re not burning. Your liver gets fat. That’s where fat production takes place. Another type of fat that your liver will synthesize is cholesterol. Again, insulin is an anabolic hormone; it manufactures fat, and it also manufactures the house for it. There are not enough cells to hold it, so it tells your body to manufacture more fat cells. Cholesterol is required in the manufacturing of all cells. It is an integral component of all cell membrane. So, as it is telling your body to manufacture cells, it is telling it to manufacture cholesterol. It is a very potent cholesterol synthesizer. In fact, it is by far the most potent. We’ll talk about this a bit later, but if you want to lower somebody’s cholesterol, pay attention to insulin, because you can do so very quickly and very powerfully. You can take cholesterol levels that were 400 or 500, and get them down to 200 in weeks if you lower a person’s insulin. Cortisol becomes increased both by a direct effect of insulin, and as a secondary effect by lowering blood sugar.

dia 0025 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.Growth hormone is decreased in light of work on DHEA. We’ve heard a lot about DHEA recently, and how wonderful DHEA is. The only known way to increase DHEA naturally is to lower insulin. High insulin lowers DHEA. We’ll show you that later. The so-called good eicosanoids are decreased, and the bad icosanoids are increased. Extremely important: Eicosanoids control so much of your body! They are the most powerful hormones known. We’ll get to eicosanoids a bit later. I won’t dwell on them right now. When we talk about eicosanoids, we’ll talk about delta-5 desaturate. That is increased by insulin. That is one of the most important enzymes in the body, in the regulation of hormones. You’re going to hear a lot about delta-5 desaturate in the future. If you regulate delta-5 desaturate, you can either be healthy, or you’re going to be sick. We’ll get into that. dia 0026 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.Insulin increases fluid retention, it increases the excretion of magnesium, potassium, and it increases sympathetic tone. It increases smooth muscle cell proliferation. It enhances endothelial cell production, and if there is ever a prescription for high blood pressure, that’s it. Essential hypertension in many circles now is being considered as caused by insulin. Where did they get “essential hypertension?” Essential for what? You talk a lot about endothelial health, and there is a lot of work, especially by George Kindness, who spoke this morning, about platelet adhesiveness. We all know that it’s really the clot that ends up actually killing us in coronary disease. When the blood is hypercoagulatable, if that’ a word, you’re going to be much more prone to coronary disease and stroke, and all sorts of other illnesses. It’s quite well known that insulin increases platelet adhesiveness.

dia 0027 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.It increases plasminogen activator inhibitor, and increases fibrinogen. It happens when we go on a chronic high-carbohydrate diet. This is new to humans. It’s an experiment. We’ve really been on a high-carbohydrate diet. We haven’t been there, not until we started cultivating lots of grains. What was around way back when, during cave man times, or whatever you call it. There is a lot of debate; were we animal eaters, or were we plant eaters. Frankly, I don’t think we cared. We just wanted to eat what was there. We ate a lot of plants. We have to examine our anatomy, the length of our intestines, our jaw, our teeth. We were somewhere between a carnivore and an herbivore. We ate both, probably a bit more toward plants because they didn’t run away. They were easier to get to. We ate a lot of plants. If there was a wounded animal, we’d eat it. We didn’t eat a bowl of rice. We didn’t eat a big bowl of pasta. We didn’t eat two loaves of bread; it wasn’t there. So, now, we’re eating a high-carbohydrate diet. That causes insulin resistance, and there is a lot of work being done. How does it cause insulin resistance. You can use the analogy: If you eat a lot of salt, (you start using salt to salt your foods, you never did before, but you do now), you start burning out the taste receptors for salt. You have to use more and more of it for foods to taste salty. Pretty soon, you have to use five tablespoons of salt, whereas a pinch of salt would have tasted just as salty months ago. It’s the same with sugar. Your taste receptors become desensitized. You walk into a smelly room, stay there a half an hour, and it doesn’t smell. Somebody else walks in, they faint. The olfactory nerve becomes desensitized. A cell becomes resistant to insulin in the same way after constantly being bombarded with it. There is a lot of work being done about insulin receptivity. That’s why the main thrust in research now in diabetes. They know that there are a fewer number of receptors when cells are constantly bombarded with insulin. They also know that with each receptor that there is decreased signal transmission. The receptor is a very complex molecule. I’m not going to get into it, because that would be an hour’s discussion right there, but there are multiple proteins involved. The insulin receptor transcends the entire membrane, and there are a number of chemical reactions that go along, — that transmit the signal into the cell. Most of them are proteins, and somehow, that receptor becomes burned out, and doesn’t work as well. You need more insulin to do the job, and you get what’s called hyperinsulinemic; you have hyperinsulinemia, to maintain your blood sugar. You’re not diabetic yet; your blood sugars are maintained. Your pancreas has a great capacity to put out a lot of insulin to keep that sugar down. Sometimes, it takes ten times as much, and we have seen patients who are putting out ten times as much insulin as a normal person to maintain their blood sugar. This person was not a diabetic. His fasting blood sugar was perfectly normal; he was just like you and me, but guess what? What did he see me for? Obesity. He was very big. He was young. What are the main causes of insulin resistance? Well, again, a lot of work is being done. We’re not sure what all the causes are. One thing we do know is that a chronic high-carbohydrate diet does that. One of the ways is by the chronic high blood sugar. You get what are called glycosylation of protein. We’ll talk a little bit more about that later, but one of the problems of high blood sugar is that that sugar combines with proteins, and causes glycosylation, and most people here have probably heard about hemoglobin A1C. That’s how you can measure long-term sugar control in a diabetic. Sugar glycosolates all proteins, and it does it to everybody, not just diabetics. If you measured your or my hemoglobin A1C, we hall have hemoglobinA1C, and all our proteins are glycosylated, and how glycosylated they are depends on how much sugar you’ve eaten. The insulin receptors themselves are made of of proteins, and they glycosylate, too. We’ll talk a little more about about the problems with glycosylation later.

Insulin resistance.

dia 0030 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.Saturated fats are known to increase insulin resistance – well known. There you go with blood sugar again. Your liver makes saturated fats out of excess blood sugar. The type of fat that your liver makes from excess sugar is a fully saturated fat. It’s not a good healthy fat; it’s a sticky, unhealthy, saturated fat; the kind you were avoiding when you ate the nonfat Fig Newton, and increasing your carbohydrates, and you just manufactured that saturated fat you were trying to avoid, but in doing so, you also increased your insulin. Is there a genetic component to insulin resistance? Well, maybe, that’s really under debate, too. There was a recent study one to two months ago in Science And Medicine that showed that insulin resistance can actually begin in utero. The mother is eating a high-carbohydrate diet, eating a lot of sugar, — partial beta cell burnout in the fetus. Perhaps it’s not so genetic. It is also known that low polyunsaturated fats increase insulin resistance. Supplementing with good polyunsaturated fat, omega 3, increases insulin sensitivity, and does so quite strongly. I cannot really go into the talk about fats, because there is s lot of controversy, but the controversy really arises in that fats can either be the healthiest component of your diet, or the most toxic. Polyunsaturated fats oxidize readily. Now try to remove it. When you go into a grocery store, you cannot find a good polyunsaturated fat; they have to take it out because it oxidizes so readily; it has no shelf life. It has to be protected. Your body has a ton of mechanisms to protect the polyunsaturated fats from becoming oxidized, and that’s really the main purpose of vitamin E. It’s incorporated into the cellular membranes right along with the polyunsaturated fat. This is a very important concept: Polyunsaturated fats are good for you; they just have to be protected. One saying to avoid polyunsaturated fats because it can oxidize readily is like saying avoid oxygen because it can oxygenate tissues. It’s crazy.

There are three main sites of insulin resistance: The liver, muscle, and fat. We’re going to talk about that a little bit more, and how important that is.

What’s the problem?

dia 0032 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.What’s the problem with hyperinsulinemia, insulin resistance, and why it is so bad? Well, the obvious problem is diabetes. We’ll talk just a little bit about diabetes. Diabetes type I is a different story and the two diabetes are really two totally different diseases with the same name. Diabetes type I is where the beta cells are destroyed. There is a strong autoimmune component, and there are autoimmune antibodies that are floating around, and something destroys the beta cells. Nobody is sure what it is; maybe it’s a virus. A lot of people implicate weak protein, but there is some sort of autoimmune reactions that is wiping out the beta cells. A true type I has very little autogenous insulin production, and that person is likely going to need insulin the rest of their life. Insulin is necessary, it’s not all bad, it is an anabolic hormone. You need it for muscle systhesis. Now, type II is a totally different story. The large majority of diabetics are type II. It is an acquired disease. It’s caused by insulin resistance; it is when insulin reduction can no longer keep up with insulin resistance. Type II diabetics produce too much insulin; I should say they produce much more insulin than the non-diabetic. It’s not a problem with not producing enough insulin, it’s a problem with insulin resistance, as cells aren’t listening, and so, the pancreas has to put out a ton of insulin to get the job done. If you want to go into details, you’re considered a diabetic if your fasting blood sugar is greater than 140, or if it is greater than 200 within the first two hours of glucose tolerance testing. I’m not big on numbers, but that means that if your fasting blood sugar is 139, you’re non-diabetic. Now, that increased insulin resistance causes an increase in hepatic glucose production. It’s no longer inhibited by the insulin. That’s very important, because the pancreas is free to churn out sugar, and continues to make a lot of sugar. dia 0033 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.It is a sugar-making factory, and does so mostly from amino acids. Again, most of the blood sugar in a 24-hour period is from hepatic production, not immediately from your diet. One of the definitions of type II diabetes is that it is a disorder in control of gluconeogenesis normally inhibited by insulin. There is also decreased muscle and fat glucose uptake, and also not on there, there is a decrease in the amino acid uptake in muscles, when you have insulin resistance. It’s very important, it gives you a fine, end-stage diabetic when the cells are no longer listening to insulin, and they cannot absorb amino acids, and they become muscle-depleted, approaching wasting.

 

dia 0034 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.Now, what about us in-between? Is your fasting blood sugar less than 140? Does your tolerance test never go above 200? We eat a high carbohydrate diet, our insulin levels are high, and we have what’s known as impaired glucose tolerance. It’s totally unknown how many people have that. It’s not normally tested. You go get a checkup, and they’ll check your blood sugar. A tiny fraction of physicians might test the fasting insulin. I told you, it’s very little. One estimation is that a third of the elderly people, another estimation is a third of the entire population, and I heard another estimation is 2/3 of all people over 65. Anyway, a lot of us have impaired glucose tolerance. We have normal blood sugar, but we have higher and delayed insulin output.

What of the affects of increased blood sugar?

dia 0035 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.Why is that so bad? Well, short-term, it’s not good because it can create an osmotic gradient in the kidney, and we pee a lot. We dehydrate, going to the bathroom all the time. We need very little insulin, actually, to prevent acidosis. That’s not really a major problem for most of us. Very high blood sugars cause fatigue, mostly because of dehydration. That’s the most immediate effect, but that’s not the real bad effect of it. The chronic effect of constant sugar in the diet is glycosylation of proteins. Constant sugar in the diet also depletes magnesium, manganese, chromium, it depletes manganese SOD, and it also reduces receptor activity. To quote from JOURNAL OF DIABETES, 03/91, “Diabetes with complications is associated with increased chemical modification of proteins and lipids, and this damage appears to be largely oxidative in origin, and is sufficient to explain the altered function of proteins in the extra-cellular matrix.”

I want to talk a little bit more about glycosylation of proteins. It affects all of our proteins, not just hemoglobin. It affects our lipoproteins. The lipoproteins become glycosylated. It’s also known that when a protein becomes glycosylated, it is a much greater target for oxidation. It increases the oxidized ability of protein when sugar is attached. Sugar becomes also a sticky baggage for that protein, and the protein can no longer function properly. It is constantly having to drag that sugar around for the life of that protein. It increases the oxidized ability of glycosylated LDL. The LDL becomes glycosylated. The HDL becomes glycosylated, it cannot function properly when it is glycated. We all have known about the damage that oxidized LDL can do. Well, glycosylated LDL is extremely oxidizable. In addition, we have sugar attached to a protein, and if there is also an attached lipid, it increases the likelihood of poor oxidation of that lipid, which also increases the oxidizability of lipoprotein. This is very important. There is an article called “The World Of Oxidative Stress and The Development of Complications of Diabetes.” This is in DIABETES, Volume 40, April 1991. “There is evidence of increased oxidative damage to collagen,” (which is a long-lived protein, and most of the oxidative damage of consequence is going to have the long-lived protein), “in diabetes. Because of the interplay between glycation and oxidation in their formation, we have termed these compounds glycosidation products. Because these products accumulate in collagen normally as a function of age, and at an accelerated rate in diabetes mellitus, diabetes mellitus may be legitimately described at the chemical level as a disease characterized by accelerated aging of collagen by glycative and oxidative mechanisms.

What are the consequences of hyperinsulinemia?

dia 0037 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.There are a lot of names for hyperinsulinemia. Syndrome X you might have heard about, and we call it CAOS, which stands for coronary artery disease, hypertension, hyperlipidemia, adult onset diabetes, obesity, and stroke. I just call it the IRS, insulin resistant syndrome; I’m not sure which is worse. There are extreme cardiovascular and cerebrovascular complications. This has been known for a long time. It takes a long time for information to get down the pipeline. Inatola Cruz did what at the time was a very famous study. Most of us, and most cardiologists, and endocrinologists have totally forgotten about this. This was done in 1961, and published in the journal CIRCULATION RESEARCH. It was titled “The effect of Intra-arterial Insulin on Tissue Cholesterol, And Fatty Acids In Diabetic Dogs.” They made dogs diabetics, and they infused insulin into the femoral arteries of those dogs for eight months. They sacrificed the dogs and examined them, and lo and behold, the femoral artery that had the insulin effused was covered with fatty streaks. The contralateral femoral artery was clear. Another study. This was done by R. W. Stout, who is still doing a lot of research. This is published in the BRITISH MEDICAL JOURNAL IN 1970. This is entitled “The Development of Vascular Lesions In Insulin Treated Animals Fed A Normal Diet.” This was done in Belfast.

Long term treatment with insulin.

dia 0038 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.“We took chickens, and we injected them with insulin for 19 weeks. We chose chickens because birds develop similar atherosclerosis as humans, and chickens in particular, because they are omnivorous. After 19 weeks, he examined their aortas, and found that there was a great increase in lipid deposits in the aortas of the insulin treated chickens as opposed to the ones who didn’t have insulin. He quotes that this provides further evidence in favor of the hypothesis that insulin and atheroma are causally related.” This was in 1970. He is continuing to do research, and he published another summation. This is in DIABETES CARE, 1990.

“Long-term treatment of insulin results in lipid-containing lesions and thickening of the arterial wall in experimental animals.” This time, they are talking about human trials.

“Insulin often inhibits regression of diet-induced experimental atherosclerosis, and insulin insufficiency inhibits the development of arterial lesions. Insulin stimulates lipid synthesis in arterial tissue.”

dia 0039 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.A quick chart, and I will not draw on it too long, but it shows the rise in incidence of coronary disease, with fasting serum insulin. One-vessel, two-vessel disease, fasting insulin rises.

Gerald Ravin is one of the pioneers in insulin resistance research, and I won’t dwell too long on this, but he is talking about some of the diseases that are clustered in insulin resistance. It talks about hypertension, glucose intolerance, hyperglycemia, upper body obesity, and they found out further now that there is a – hypertension resistance to the insulin hyperinsulinemia, glucose intolerance, increased VLDL triglyceride, reduced HDL cholesterol activator inhibitor, and fibrinogen levels.

dia 0047 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.

What else does it do? We just talked about hyperlipidemia, and increased cholesterol synthesis. It increases small, dense LDL particles. We go on in our research about the detrimental effects of lipids, and first it was cholesterol, and if not cholesterol, it’s LDL cholesterol and cholesterol is good, and then we find that it is oxidized LDL. There is a type of LDL particle that is called a small, dense LDL particle, and that is the type of particle that is preferentially manufactured in the liver by insulin. We’ll talk about that in a minute. It increases HMG coenzyme A reductase. When you lower insulin, you inhibit that. When you increase glucagon, you inhibit that. Sounds like Mevacor, only without the adverse side affects of stopping co Q-10 production, (and other enzymatic reactions in the liver). It increases LDL oxidizability, and that is very important. It decreases HDL, it increases arterial wall thickening via endothelial proliferation. It increases fluid retention, as we talked about earlier. It increases blood pressure, and it increases clot formation. It decreases natural killer cells, and it increases cancer because of that, it decreases T-helper cells. It increases sympathetic tone. It increases prostaglandin E-2. Solvetti out of ——Italy, in an article titled “The Interrelationship Between Insulin Resistance And Hypertension.”

“Insulin can increase blood pressure via several mechanisms: increased renal, sodium, re-absorption, activation of sympathetic nervous system, alteration of trans-membrane, ion transport, and hypertrophy of resistance vessels. Hypertension can cause insulin resistance by altering delivery of insulin, and glucose into the muscle cells, resulting in impaired glucose uptake.” You have a vicious cycle.

In ——-, by Dr. Austin, called “Low Density Lipoprotein Subclass patterns, and Risk of MI.”

“The LDL subclass pattern characterized by small dense LDL particles was significantly associated with a three-fold increase risk of MI, independent of age, sex, and relative weight.”

Going on in the journal CIRCULATION, in 1993, “Small dense LDL is an integral feature of the insulin resistance syndrome.”

Gerald Reavin, in reviewing some of the literature titled “Syndrome X,” Six Years Later, “resistance to insulin stimulated glucose uptake, the common phenomenon, occurring in approximately 25% of the population, is associated with a number of risk factors for coronary heart disease, including hyperinsulinemia, abnormal glucose tolerance, non-insulin dependent diabetes mellitus, increased plasma triglycerides, and decreased HDL, denser LDL particles, hypertension, and abnormalities of fibrinolysis.”

It is hard to be healthy like that.

Another important researcher, Zavaroni in Italy, JOURNAL OF INTERNAL MEDICINE, entitled “Hyperinsulinemia, or ——- syndrome X.

dia 0049 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.“Hyperinsulinemic subjects are found to be relatively glucose intolerant, have higher triglyceride and uric acid concentrations in blood pressure, lower HDL cholesterol when compared with normal insulinemic individuals, but importantly, the difference in the degree of obesity had little affect on the variables measured when individuals were matched for insulin response.” In other words, it’s not their obesity that’s causing this. That is an important article.

Insulin causes obesity. Obesity can also lead to insulin resistance, but it isn’t the obesity that is causing the hypertension, and all these other problems; it’s the insulin. This is from David Belle.

“Insulin resistance, an often unrecognized problem, accompanying chronic medical disorders. Several population studies have shown that hyperinsulinemia is the independent risk factor for atheroschlerosis.” I think we are figuring that out. “Insulin resistance is associated with a number of risk factors for atherosclerisis, including glucose intolerance, hypertension, and dyslipidemia. Management should include attempts to reduce insulin resistance, and certainly not increase it.” Remember that! This is another article that we will get to a little bit later.

This is a very recent article, January 1996. This is a Japanese group, out of Osaka, Japan, that decided to do angiograms, and measure insulin. They put it in language that cardiologists can understand. They can understand angiograms, and anything else is a foreign language.

In conclusion;

dia 0110 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.“In conclusion, these data suggest that in patients with coronary artery disease, insulin-medicated glucose metabolism is significantly impaired, and correlation is noted between insulin resistance and severity of coronary artery disease. Hyperinsulinemia may stimulate the artheromatous process.” This is in DIABETES CARE, January 1996.

dia 0055 300x201 Insulin:  Its Crucial Role in Chronic Illness  – Ron Rosedale.  Part 1 of 2.What about obesity? Insulin makes you fat. Insulin is an anabolic hormone. It is a storage hormone. Its’ main purpose in life is to store energy. Another important aspect of insulin is that it inhibits lipolysis very strongly. It wants you to store that energy, and it doesn’t want you to burn it. It’s a protective mechanism. Food, way back when in caveman times, wasn’t abundant all the time. It was feast or famine. We had a lot of it sometime, and we didn’t have a lot of it sometimes, especially in the wintertime. Insulin is really developed to store that energy. It was a protective mechanism. Insulin causes an increased abdominal fat. It is an independent risk factor. Apple versus pear shape; we talked about being an independent risk factor. Insulin increases fat cell number. That is important.

This talk was given in 1995, and it is quite surprising that it is still new information today.  It has long been said by experts in the field that Dr. Rosedale is a pioneer and at least 10 years ahead of the curve.

    Hello Dr.Rosedale,

    It’s always a pleasure to read your work.

    What possible explanations would you put forward to explain the highly abnormal ApoB number (7.5mmol/L) in a 23 year old following a high-fat, adequate protein, low-carb (sub 15%) diet living between Southern France and The Netherlands.

    (Assuming weekly exercising and a whole-real-foods diet)

    Thank you for your time!

    Can high fiber vegetables make you insulin resistant? Also if I wanted to do a feast or famine style diet how many days do you think I should fast. Would it be okay if I exercised and fasted for say 12 hours after awaking and gorged on high fiber veggies and protein at night while being active for 3 hours after the feast. I did very well on a one meal feast at night while being active during the day. By active I mean on my feet the entire day. I found a study on sitting time and it found that for people on the standard american diet risk goes up with every hour of sitting so I started walking while working and studying and this has allowed me to get very lean almost too lean. Also I found out that sprinting exercise is so effective because it empties muscle and liver glycogen which increases insulin sensitivity rapidly. If I wanted to do the one meal a day thing I know I would have to do sprinting and walking. Sprinting takes very little time about 40 minutes a day broken up into 15 minute segments so I now I could empty my sugar stores. Walking burns more fat than sugar but for some reason studies say calorie for calorie walking is just as good as sprinting though sprinting takes less time and goes straight for the sugar. I need a little guidance. I am 28 and I want to make the right choice so that I age better. Any guidance would be appreciated.

    Kind of unusual to see a mainstream media and mainstream researcher (Harvard) to make this argument

    Harvard Doctor Refutes Milk Recommendations
    http://shine.yahoo.com/healthy-living/harvard-doctor-refutes-milk-recommendations-185215063.html

    though making an argument like “substituting fat with sugar is bad” needs no intelligence.

    Dr. Rosedale,

    There is letter circulating around about doing some tests as recommended by you (http://healthticket.blogspot.com/2013/04/16-medical-tests-and-leptin-and-insulin.html). The letter was probably compiled by someone from Malaysia.

    I am wondering if you have some info about tests of these key measures in the United States. As you know, most doctors don’t really care about them. And insurance companies may not cover them at all. Those are just some challenges. But first of all, I need to know where I can test them.

    Would appreciate your feedback.

      From the Rosedale Team. Thank you for the link. Dr. Rosedale mostly does his tests through LabCorp, they do offer a discount if payment is paid in full right there and then.

    Hello Dr.Rosedale

    just point of clarification for you.Here in Canada we do not call the northern aboriginal people Eskimo anymore.The like to be called Inuit.I would also like to let you know that in the last 50 years or so (post WWII) since the expansion of the Northern Stores the Inuit are now a very sick people and have very high suicide rates.They no longer eat in their traditional ways but rather eat the typical Western diet.If you really wanted to do a study on how foods impact the human body you should consider looking into how the Inuit and the Fist nations people have gone from a healthy people to a sickly diseased one in less than 100 years.

    Part of this article is confusing to me. If insulin tells the liver to make fat cells because of sugar floating in the blood stream and also tells the liver to produce more cholesterol because it is required in the manufacturing of all the cells, and that is why you have high cholesterol; then how come my fast insulin level is 3 (which means my blood stream is not loaded with sugar) but my total cholesterol is 320. Doesn’t this contradicts what is mentioned in the article in this regard?

    The insulin tolerance test with 15 minutes of readings on glucose response sounds like a low-impact and great test. Can Dr Rosedale recommend any lab in California that offers this test, or any Endo in California who uses this test in his practice? No one I know seems to know anything about this test.

    This post mentions that insulin may upregulate HMG CoA Reductase, resulting in more endogenous cholesterol production. Is there any test available that would:

    1) Measure active levels of HMG CoA Reductase, so that we could establish some baseline against a larger population of people who have normal glucose metabolism?

    2) Determine if there is any defect in the HMG CoA Reductase genes? When you eat a high cholesterol diet, the body is supposed to downregulate HMG CoA Reductase. Is there any way to test if that biology is working correctly?

    Familial hypercholesterolemia involves various kinds of defects in the LDL receptors, with the result being that the body cannot extract cholesterol out of LDL, and excess LDL sits in the blood unprocessed. So the question in 2) is about whether there is a way to test for similar kinds of defects in the HMG CoA Reductase biology of a given individual. There are genetic tests now for Familial hypercholesterolemia.

    At the bottom of the page, it states that this talk was given in 1995 however, Dr. Rosedale quotes reports from January 1996. What gives? I’m looking for accuracy when trying to explain a low-carb lifestyle, and that healthy fats are just that; healthy.I myself take no offense,thinking it may be a minor error; however proponents of a high-carb low-fat lifestyle look at any indiscretion, as a chance to throw the baby out with the bath water.

    I really enjoyed this article series and was hoping I could clarify something.
    In Part 1 of the talk it says:”Saturated fats are known to increase insulin resistance” referring to the saturated fats that the liver makes out of excess blood sugar.
    And then in part 2 about animals on a grain fed diet – “the fat that is manufactured in these animals is very saturated fat. It’s a very poisonous toxic fat. It is because most of the fat that we are eating is a byproduct of carbohydrate metabolism.” And then it goes onto say that “fat in itself is not bad” but that it’s the “artificially manufactured” fat that is the problem.

    It sound like you are saying that the fat stored in an animal manufactured from carbohydrates is worse than other saturated fat found in an animal. Have I understood this correctly? If so, I find this intriguing – do you know if there are any references for the difference in the types of fats generated by different processes in an animal?

    Hi, What about someone with chronic reactive hypoglycemia / hyperinsulinemia (does not have insulin resistance).

    I take it that ketogenic diet’s helps lower insulin levels? How does one stay on it with out feeling like crap all the time?

    Any hint of food (even low carb, protein or even fat) and will trigger a big insulin dump. In a few days on it the pancreas “heals” and becomes more efficient at secretion.
