No more Lovaza

That's it: I will NEVER ever write another prescription for Lovaza.

I actually very rarely write a prescription for Lovaza, i.e., prescription fish oil. But this was the last straw.

I advised a patient that we've had good success using high-doses of fish oil to reduce lipoprotein(a), Lp(a). 6000 mg per day of the omega-3 component (EPA + DHA) from fish oil reduces Lp(a) in 60% of people after one year. (Recall that Lp(a) is the most aggressive known lipid-related cause of heart disease.)

The two preparations I generally suggest are either the very affordable Sam's Club Members Mark Triple-Strength Fish Oil with 900 mg EPA + DHA per capsule: 7 capsules per day. Another great product (my personal favorite because of its extreme purity--it doesn't even smell like fish oil): Pharmax Finest Pure Fish Oil with 1800 mg EPA + DHA per teaspoon: 3 to 3 1/2 teaspoons per day.

Both preparations work great and are quite affordable, given the high dose. For the Sam's Club preparation, it will cost around $30 per month, while the Pharmax liquid will run around $49 per month.

Well, the woman's husband insisted on a prescription for Lovaza. One Lovaza capsule contains 784 mg EPA + DHA per capsule: 7 to 8 capsules per day.

Here are some prices for Lovaza from online pharmacy discounters:
Prescription Giant: $78.99 for 30 capsules ($2.63 per capsule)
Planet Drugs Direct: $135 for 100 capsules ($1.35 per capsule)

These are lower than the prices I obtained in past by calling local pharmacies in my area, quite a bit lower, in fact.

Filling the Lovaza prescription at Prescription Giant will therefore cost $552.93 to $631.92 per month; at Planet Drugs Direct it will cost $283.50 to $324.00 per month. At local pharmacies, a similar 7 to 9 capsules Lovaza per day will cost upwards of $800 to $900 per month.

The patient's husband insisted on the Lovaza prescription because he knew that his insurance would cover it. When I pointed out that this was a large cost that would have to be borne by others in their healthcare premiums, he said that didn't matter to him.

I hesitated, but ended up writing the prescription for 7 Lovaza capsules per day. As soon as I handed to him, I regretted it. In fact, I am embarassed and angry at myself for having given in.

So I vowed: I will NEVER EVER write another prescription for Lovaza.

I do not believe that we should spread the excessive profiteering of the pharmaceutical industry around on the backs of people who pay their healthcare insurance premiums, just so that a few people, like this selfish couple, can save a few dollars a month.

This is your brain on wheat II

In the original Heart Scan Blog post, This is your brain on wheat, I discussed how opioid peptides (i.e., small proteins that act like opiates such as heroine or morphine) that result from digestion of wheat cause unique effects on the human brain, particularly addictive behaviors. I also briefly reviewed how elimination of wheat has been shown to reduce auditory hallucinations and other psychotic behaviors in a subset of people with paranoid schizophrenia.

These two phenomena, addictions and schizophrenia, are most likely the result of exorphins that cross the blood-brain barrier. Exorphins--exogenous morphine-like compounds--can be blocked by opiate-blocking drugs like naloxone and naltrexone. Naloxone is used in hospitals to reverse morphine or heroine overdoses; naltrexone is being repackaged into a weight loss drug, since blocking wheat-derived exorphins reduces appetite. (Yes: The USDA tells us to eat more wheat, the drug industry sells us the antidote.)

There's another way that wheat can affect the brain and nervous system: immune-activated damage.

This is similar to the effect seen in celiac. There's even overlap with some of the antibody markers used to diagnose celiac, like the anti-gliadin antibodies and the anti-endomysium antibodies.

The most common immune neurological syndrome consequent to wheat consumption is cerebellar ataxia, a condition in which an immune response causes damage to the Purkinje cells of the cerebellum, the portion of the brain responsible for balance and coordination. This results in stumbling, incoordination, incontinence, and eventually leads to reliance on a cane or walker and wearing a diaper. Average age of onset: 53 years. A shrunken, atrophied cerebellum can be seen on an MRI of the brain.

Problem: Most people with central nervous system damage caused by wheat do not have any intestinal symptoms, like diarrhea and abdominal pain, the sort of symptoms usually associated with celiac disease. It means the first sign of wheat-induced brain damage may be bumping into walls and wetting your pants.

There's no such thing as a "no-carb" diet

When I tell patients how I advise a wheat-free, cornstarch-free, sugar-free diet on the background of a low-carbohydrate diet, some people ask: "But can I live on a no-carb diet?"

Well, there's no such thing as a "no-carb" diet. Low-carb, yes. No-carb, no.

Here are the carbohydrate contents of various "low-carb" foods:

Gouda cheese--3 oz contains 1.65 grams carbohydrates
Mozzarella cheese--1 cup contains 2.89 grams carbohydrates
Walnuts--4 oz (56 nuts) contains 2.96 grams carbohydrates
Almonds--4 oz contains 1.38 grams carbohydrates
Sour cream--one-half cup contains 3.31 grams carbohydrates
Red wine--3.5 oz glass contains 2.69 grams carbohydrates
Eggplant--1 cup cooked contains 8.33 grams carbohydrates
Green pepper--1 medium-sized raw contains 5.52 grams carbohydrates
Cucumber--1 medium contains 4.34 grams carbohydrates
Tomato--1 medium contains 4.82 grams carbohydrates

(Nutrition data from USDA Nutrient Database)

In other words, foods thought to be "low-carb" actually contain a modest quantity of carbohydrates.

Such modest quantities of carbohydrates may not be enough to trip your blood sugar. But add up all the "low-carb" foods you consume over the course of a day and you can easily achieve 30 grams or more carbohydrates per day even without consuming any higher carbohydrate foods.

Why doesn't your doctor try to CURE diabetes?

Imagine you have breast cancer. You go to your doctor and she says, "As your pain worsens, we'll help you with pain medication. We'll fit you with a special bra to accommodate the tumor as it grows. That's all we're going to do."

"What?" you ask. "You mean just deal with the disease and its complications, but you're not going to help me get rid of it . . . cure it?"

It would be incredibly shocking to receive such advice. Then why is that the sort of advice given when you are diagnosed with diabetes?

Say you go to the doctor. Lab values show a fasting blood sugar of 156 mg/dl, HbA1c (a reflection of your previous 60 days average glucose) of 7.1%. Both values show clear-cut diabetes.

Your doctor advises you to 1) start the drug metformin, then 2) talk to the diabetic teaching nurse or dietitian about an American Diabetes Association (ADA) diet.

The ADA diet prescribed encourages you to increase carbohydrates and cut fats at each meal and maintain a consistent intake so that you don't experience hypoglycemic (low blood sugar) episodes. You follow the diet, which causes you to gain 10-15 lbs per year, increasing your "need" for diabetes medication. You doctor adds Actos, then Januvia, then injections of Byetta.

Three years and 34 lbs later, you are not responding well to the drug combination with blood sugars rarely staying below 200 mg/dl. You've developed protein in your urine ("proteinuria"), lost 30% of your kidney function, and you are starting to lose sensation in your feet. So the doctor replaces some of your medication with several insulin injections per day.

This formula is followed millions of times per year in the U.S. So where along the way did your doctor mention anything about a "cure"?

Adult diabetes is the one chronic disease that nobody cares to cure. Treat it, maintain control over blood sugars, but cure it? Most physicians say it's impossible.

The tragedy is that diabetes is a curable condition. I've seen it happen many times. Physicians dedicated to curing diabetes like low-carb expert, Dr. Mary Vernon, have cured it countless times. Dr. Eric Westman and colleagues have been building the case for the carbohydrate-restricted cure for diabetes with studies such as this. In this last study, of the 8 participants on insulin + medications at the start of the study, 5 no longer required medications at the close of the study--they were essentially non-diabetic.

I tell patients that diabetes, in fact, is a disease you choose to have or not to have--provided you are provided the right diet and tools. Sadly, rarely are diabetics told about the right diet and tools.

That's why Cadbury Schweppes has been a major contributor to the American Diabetes Association, as are other processed food manufacturers and the drug industry, all who stand to profit from maintaining the status quo.

The cure? Eliminate or at least dramatically reduce carbohydrates, the foods that increase blood sugar.

Note: If you have diabetes and you are taking any prescription agents, such as glyburide, glipizide, insulin, and some others, you will need to discuss how to manage your medications if you reduce carbohydrates. The problem is finding a doctor or other resource to help you do this.

LDL pattern B

Here's a Q&A I stumbled on in the Forum of MedHelp, where people obtain answers from presumed health "experts."

Question:

My VAP test results in July 07 identified an LDL Pattern B.
Overall results:
Total 150
HDL 75
LDL 61
Trig 60
HDL-2 17
LP(a) 6.0
LDL Pattern B

Medications:
Lipitor 10mg
Zetia 10mg
Altace 10mg
Atenolol 50mg
Plavix 75mg
Aspirin 81mg

I had several heart attacks which resulted in CABG performed May 2000. I am a 53 year old white male , 6'1", 190 pounds, exercise every day, watch my diet and feel great. Everything looks OK except my LDL Pattern B. Is there any therapy to improve the Patten B?


Answer from CCF, MD:
Your results indicate an LDL pattern B, which generally indicates small atherogenic LDL particles which may cause increased risk for CAD. However, there are several problems with LDL patterning: 1) its unreliability (of LDL pattern testing ), 2) unclear clinical evidence regarding regarding the usefulness of LDL patterns and particle size. The majority of evidence regarding the progression of atherosclerosis is with LDL lowering and to an smaller extent HDL raising.

All available clinical evidence shows that any particles in the VLDL, IDL, or LDL range are atherogenic, and there is no evidence that whether belonging to pattern A or B one is more atherogenic than others.

Subclass studies have proliferated over the last few years, but many of these studies were funded or subsidized either by suppliers of the assays as a method to expand their use and move them into mainstream practice, or by pharmaceutical companies in an attempt to claim some advantage over other therapeutic agents.
Thus, current data on LDL subclasses are at best incomplete and at worst misleading, suffering from publication bias, and now given the recent results of the Ensign et al. study, unreliable.

Your LDL, and HDL are at goal. The Lpa level is still not clearly linked as a modifiable risk factor for CAD, although elevated levels are now know to be linked to stroke.

Continue with your present treatments: aspirin, plavix, ateonol and altace are all essential medications.



Wow. The extent of ignorance that pervades the ranks of my colleagues is frightening.

Contrary to the response, LDL particle size assays are quite reliable and accurate. I've performed many thousands of lipoprotein assays and they yield reproducible and clinically believable results. For example, eliminate wheat, oats, cornstarch, and sugars and small LDL drops from 2400 nmol/L to 893 nmol/L (NMR)--huge drops. If repeated within a short period of time, the second measure will correspond quite closely.

The data are also quite clear: Small LDL particles (i.e., "pattern B") are a potent predictor of cardiovascular events. What we lack are the treatment trials that show that reduction of small LDL results in reduced cardiovascular events. The reason for this is that small LDL research is not well-funded, since there is no prescription drug to treat small LDL, only nutritional means. Niacin (as Niaspan) is as close as it comes for a "drug" to reduce small LDL. But diet is far more effective.

Given the questioner's fairly favorable BMI of 25.1 and his history of aggressive heart disease, it is virtually certain that he has what I call "genetic small LDL," i.e., small LDL that occur on a genetically-determined basis (likely due to variants of the cholesteryl-ester transfer protein, or CETP, or of hepatic lipase and others).

Ignoring this man's small LDL will, without a doubt, consign him to a future of more heart attacks, stents, and bypass. Maybe by that time the data supporting the treatment of small LDL will become available.

What increases blood sugar more than wheat?

Take a look at these glycemic indexes (GI):


White bread 69
Whole wheat bread 72
Sucrose 59
Mars bar 68
White rice 72
Brown rice 66


I've made issue in past of whole wheat's high GI--higher than white bread. Roughly in the same glycemic league as bread are shredded wheat cereal, brown rice, and a Mars candy bar.

With few exceptions, wheat products have among the highest GIs compared to the majority of other foods. For instance:


Kidney beans 29
Chick peas 36
Apple 39
Ice cream 36
Snickers Bar 40


Yes, by the crazy logic of glycemic index, Snickers is a low-glycemic index food.

While I do not believe that low GI makes a food good or desirable, since low GI foods still provoke high blood sugars, small LDL particles, trigger glycation, and other abnormal phenomena, they are clearly less obnoxious than the items in the first list.

Take a look at this list:

Cornflakes 80
Rice cakes 80
Rice Krispies 82
Rice pasta, 92
Instant potatoes 83
Tapioca 81



Starches that are dried and/or pulverized, such as cornstarch, potato starch, rice starch, and tapioca starch (cassava root) will increase blood sugar even more than wheat. Foods with these starches have GI's of 80-100.

Cornstarch, potato starch, rice starch, and tapioca starch: Sound familiar? These are the main starches used in "gluten-free" foods. A hint of the high GI behavior of these dried starches is seen in the GI for cornflakes of 80.

So remember: Wheat-free is not the same as gluten-free. Gluten-free identifies junk carbohydrates masquerading as healthy because they don't contain one unhealthy ingredient, i.e. wheat.

China fiction?

Dr. Colin Campbell caused a stir with publication of his 2005 book, The China Study. Dr. Campbell, after extensive animal and epidemiologic research conducted in China over 20 years, concluded that a diet high in animal protein, especially casein, was associated with increased cancer, osteoporosis, and heart disease risk.

Richard Nikoley of Free the Animal and Stephan Guyenet of Whole Health Source have been talking about an analysis of the China Study raw data performed by a young woman named Denise Minger.

Denise's analysis is nothing short of brilliant, absolutely "must" reading for anyone interested in nutrition.

Her comments on the relationship of wheat to heart disease:

Why does Campbell indict animal foods in cardiovascular disease (correlation of +1 for animal protein and -11 for fish protein), yet fail to mention that wheat flour has a correlation of +67 with heart attacks and coronary heart disease, and plant protein correlates at +25 with these conditions?

Speaking of wheat, why doesn’t Campbell also note the astronomical correlations wheat flour has with various diseases: +46 with cervix cancer, +54 with hypertensive heart disease, +47 with stroke, +41 with diseases of the blood and blood-forming organs, and the aforementioned +67 with myocardial infarction and coronary heart disease?

Carbohydrate-LDL double whammy

Carbohydrates in the diet trigger formation of small LDL particles. Because carbohydrates, such as products made from wheat, increase triglycerides and triglyceride-containing lipoproteins (chylomicrons, chylomicron remnants, VLDL, and IDL), LDL particles (NOT LDL cholesterol) become triglyceride-enriched. Triglyceride-enriched LDL particles are "remodeled" by the enzyme, hepatic lipase, into triglyceride-depleted, small LDL particles.

The list of reasons why small LDL particles are more atherogenic, i.e., plaque-causing, is long:

--Small LDL particles, being smaller, more readily penetrate the endothelial barrier of the arterial wall.
--Small LDL particles are more adherent to glycosaminoglycans in the artery wall.
--Small LDL particles are poorly taken up by the liver LDL receptor, but enthusiastically taken up by macrophage receptors of the sort in your artery walls.
--Because of their poor liver clearance, small LDL persists in the bloodstream far longer than large LDL.
--Small LDL particles are more oxidation-prone. Oxidized LDL are more likely to trigger inflammatory phenomena and be taken up by macrophages in the artery wall.

Let me add another reason why small LDL particles are more likely to cause plaque: They are more likely to undergo glycation. (More on glycation here.)

Glycation occurs when glucose (sugar) molecules in the blood or tissue modify proteins, usually irreversibly. Small LDL particles are uniquely glycation-prone. (This is likely due to a conformational change of the apoprotein B in the small LDL particle, exposing lysine residues along apo B that become glycated.)

Here's a great demonstration of this phenomenon by Younis et al:


"LDL3" is the small type. Note that small LDL particles are 4-5 times more glycated than large LDL. That's a big difference.

Once glycated, small LDL is especially resistant to being taken up by the liver. Like annoying in-laws, they hang around and hang around and . . . The longer they hang around, they more opportunity they have to contribute to plaque formation.

So, carbohydrates trigger formation of small LDL particles. Once formed, small LDL particles are glycated when blood sugar increases. While LDL can be glycated even when blood sugars are in the normal range (90 mg/dl or less), glycation goes berserk when blood sugars go higher, such as a blood sugar of 155 mg/dl after a bowl of steel-cut oatmeal.

To lose weight, prick your finger

We know that foods that trigger insulin lead to fat storage. Putting a stop to this process allows you to mobilize fat and lose weight. If you're starting out from scratch, rapid and dramatic weight loss can be experienced, as much as one pound per day.

So how can you stop triggering insulin?

The easiest way is to eliminate, or at least minimize, carbohydrates. My favorite method to restrict carbohydrates is to eliminate wheat and minimize exposure to other carbohydrates, such as oats, cornstarch, and sugars. All these foods, wheat products worst of all, cause blood sugar and insulin to skyrocket.

Another way is to check your blood sugar one hour after completing a meal and keep your after-eating, or "postprandial," blood sugar 100 mg/dl or less. Let's say you are going to eat stone ground oatmeal, for example. Blood sugar prior to eating is, say, 90 mg/dl. One hour after oatmeal it's 168 mg/dl--you know that this is going to trigger insulin and make you fat. Oatmeal should therefore be eliminated.

Keeping blood sugar to 100 mg/dl or less after eating teaches you how to avoid provocation of insulin. A shrinking tummy will follow.

To do this, you will need:

1) A glucose meter--My favorite is the One Touch Ultra Mini ($13.42 at Walmart). It's exceptionally easy to use and requires just a dot of blood. Drawback: Test strips are about $1 each. Accuchek Aviva is another good device. (We've had a lot of problems with Walgreen's brand device.)
2) Test strips--This is the costly part of the proposition. Purchased 25 or 50 at a time, they can cost from $0.50 to $1.00 a piece.
3) Lancets--These are the pins for the fingerstick device that comes with the glucose meter. A box should be just a few dollars.

No prescription is necessary, nor will insurance pay for your costs unless you're diabetic. To conserve test strips, use them only when a new, untested food or food combination is going to be consumed. If you had two scrambled eggs with green peppers, sundried tomatoes, and olive oil yesterday and had a one hour postprandial glucose of 97 mg/dl, no need to check blood sugar again if you are having the same meal again today.

Iodine update

As the iodine experience grows, I've made several unique observations.

Up to several times per day, I see people who are responding in some positive way to iodine supplementation. (See previous Heart Scan Blog posts about iodine: Iodine deficiency is REAL and The healthiest people are the most iodine deficient.)

Among the phenomena I've observed:

1) A free T4 thyroid hormone at the low end of normal, or even in the below normal range, along with a highish TSH (usually >1.5 mIU/L) are the most frequent patterns that signal iodine deficiency. Occasionally, a low free T3 value will also increase, though this is the least frequent development.

2) At a dose of 500 to 1000 mcg iodine per day, it requires anywhere from 3 to 6 months to obtain normalization of thyroid measures.

3) Reversal of small goiters also occurs over about 6 months.

4) Iodine intolerance is uncommon. If it occurs, using a low starting dose, e.g., 100-200 mcg per day, usually works. The dose can be increased gradually over the ensuing months.

5) Perceptible benefits of iodine occur only occasionally. The most common perceptible effects are increased energy and increased warmth, especially of the hands and feet.

6) Some people who have taken thyroid hormones for years will develop reduced need for their medication with iodine supplementation. In other words, their physician was inadvertently treating iodine deficiency with thyroid hormone replacement. Anyone already on any thyroid preparation(s), e.g., Synthroid, levothyroxine, Armour thyroid, Naturethroid, etc., should watch for signs of hyperthyroidism when iodine is added. But having your own thyroid gland make its own thyroid hormones is better and healthier than relying on the prescription agents. Just be sure to monitor your thyroid measures.

7) Iodine toxicity can occur--Two people in my clinic population developed iodine toxicity by taking 6000 mcg iodine per day for 6 or more months. (Both patients did it on their own based on something they read). Iodine toxicity is evidenced by shutting down your thyroid, i.e., marked increase in TSH, e.g., 15 mIU/L.


Most of the people in my clinic obtain their iodine from kelp tablets. Some use potassium iodine (KI) drops. A handful have used the high-potency Iodoral (12.5 mg or 12,500 mcg iodine per tablet); this was also the form that generated the toxic effects in the two females.

All in all, iodine deficiency is actually far more common than I ever suspected. Not everybody is iodine deficient. But a substantial minority of the Midwest population I see certainly are.
AGEing gracefully

AGEing gracefully

Advanced Glycation End-products, or AGEs, have the potential to change our entire conversation about diet.

AGEs come from two principal sources:

1) Endogenous--Glucose-protein interactions that arise from high blood glucose levels

2) Exogenous--From diet

The first is sensitive to glucose levels: the higher the glucose level, the greater the AGE formation. The second depends on the quantity of AGE in the food consumed.

A compelling body of evidence points towards AGEs as an agent of aging, as well as kidney dysfunction, dementia, and atherosclerosis. Some of the observations made include:

--If AGEs are infused into an experimental animal, it develops atherosclerosis, kidney disease, and other "diseases of senescence" within weeks to months.

--In endothelial cells (cells lining arteries), AGE induces expression of adhesion molecules and inflammatory signals. In fibroblasts, AGE provokes collagen production. In smooth muscle cells, AGE triggers migration and proliferation. In monocytes and macrophages, AGEs induce chemotaxis and release of inflammation mediators. In short, AGEs have been implicated in just about every step leading to atherosclerosis.

--In humans, greater quantities of AGEs are present in diabetics, pre-diabetics and people with insulin resistance. We all know that these people develop atherosclerosis, kidney disease, cataracts, and other conditions at an accelerated rate.

--Foods containing greater quantities of AGEs cause endothelial dysfunction, i.e., artery constriction via blockade of nitric oxide and other mechanisms.

Short of taking agents that block AGE activity, how can you minimize the absorption or production of AGEs? There are two general strategies:

1) Keep blood glucose low--The Whitehall study demonstrated increased cardiovascular mortality with a postprandial (actually 2-hour post- 50-gram glucose challenge) blood sugar of 83 mg/dl. Lower blood glucose, less glycation. Less carbohydrates in the diet, the lower the blood sugar, the less the glycation. Studies like Whitehall demonstrate that glycation begins with glucose values within the normal range. Thus, aging occurs even with normal glucose levels. It occurs faster with higher glucose levels.

2) Choose and prepare foods with lower AGE content. Food content of AGEs is a major determinant of blood AGE levels. Fats and meats are the primary dietary source of AGEs, particularly if cooked at high temperature (broiling, frying). While this does not mean that meats and fats need to be avoided, it can mean that limiting serving size of meats and fats, while being selective in how they are prepared, are important. This can mean cutting your meats in thinner slices or smaller pieces to permit faster cooking, eating rare when possible (not poultry, of course), avoiding cooking with sauces that contain sugar (which enhances AGE formation). Is this an argument in favor of sashimi?

Minimizing exposure to AGEs, endogenous or exogenous, has the potential to slow the aging process, or at least to lessen the likelihood of many of the phenomena of aging.

More on this to come.

    I'm more worried about endogenous AGEs; exogenous the evidence seems a bit more mixed.

    Are food advanced glycation end products toxic in biological systems?

    Chuyen NV, Arai H, Nakanishi T, Utsunomiya N.

    Japan Women's University, Department of Food and Nutrition, 2-8-1 Mejiro-dai, Bunkyo-ku, Tokyo 8681, Japan. nvc@fc.jwu.ac.jp
    Abstract

    Model food advanced glycation end products (AGEs) were prepared as glycated casein (GC) and glycated soy protein (GS) by the reaction of casein or soy protein with glucose at 50 degrees C, relative humidity 75% for seven days in a powder state. These browned proteins were used as materials for animal experiments. A mixture of 20% glycated proteins (GC:GS = 1:1) diet was fed to streptozotocin (STZ)-diabetic rats for 11 weeks. The results showed that: (1) fructoselysine was observed in the hepatic portal veins, arteries, and femoral veins of rats fed with glycated proteins after 2 h of feeding; (2) blood sugar of glycated protein-fed rats was lower than that of diabetic rats fed with intact protein, while HbA1C in blood and glucose in urine of both groups were similar; (3) lipid peroxidation status in serum, liver, and kidney of both groups was similar; (4) superoxide dismutase (SOD) and glutathione-S-transferase (GST) enzymatic activity in serum and liver of both groups were also similar; (5) there were no differences in degree of cataract formation and concentration of glucose, fructose, sorbitol, and lipid peroxide in the lenses of both groups. From the above results, it can be estimated that food AGEs are not toxic in biological systems, and reactive oxygen species increase in diabetic rats is not caused by glycated proteins but by other pathways.

    PMID: 16037268 [PubMed - indexed for MEDLINE]

    Unfortunately, starches have much lower AGE content. Any preparation of meat has large amounts, though still variable. This might be why high-carb diets work well for traditional societies where obesity is not common.

    Less carbs, less meats, less fats--sounds like you're just promoting calorie restriction since that doesn't leave much that you can eat in significant quantities.

  • Denny Barnes

    5/5/2010 12:16:33 PM |

    Looking forward to your future writings on AGEs. I hope you will talk about the role of fructose which can form ten times as many AGEs as glucose. Not all carbs are created equal. As a fellow T2 diabetic, I think we focus too much on blood glucose and miss the stealth carb -- frutose.  It is by far the most insidious.

    Forgive me for saying it, but I feel that the ghost of your vegetarian past still haunts your writing.  Yes, barbecued, fried and broiled meats can have way too much AGEs, especially if cooked with sweet sauces, but animal protein cooked with water has 1/10 as many AGEs. I am a happy carnivore who loves stewed meats and chicken and steamed fish.

    Then there's ketosis which stimulates something called chaperone-mediated autophagy (CMA). This process is basically the recycling of junk protein. AGEs would constitute such junk. So it's not only a question of low blood glucose but of ketosis as well. Incidentally, if one eats only meat or very little carbs, then he will be in ketosis most of the time. In that sense, it doesn't matter how much AGEs come from this diet since the same diet would provide the recyclers as well. Here's the post by Eades on the subject:

    Supporting your point regarding endogenous AGEing, there is also reliable evidence that blood glucose control before age 55 may increase your chances of living beyond 90:

    http://healthcorrelator.blogspot.com/2010/04/blood-glucose-control-before-age-55-may.html

    However, I am yet to see reliable evidence that significant damage can be caused by ingested AGEs through cooked meat and fat (e.g., resulting from Maillard reactions).

    I don't doubt that injecting AGEs into model animals, particularly rodents, will lead to problems. But human digestion in a healthy person (e.g., no leaky gut) is another story. Moreover, cooked meat is denatured and thus rendered more easily digestible.

    Thanks for the post Dr. Davis!

    I would love to get info on what happens to the body as you are lowering your blood sugar via diet.  I have been using a monitor and feel my best at around 85 but at times crave sugar pretty bad and have energy spikes and dips.  I exercise too, so curious how this factors in?

  • Apra -- The Shaman

    5/5/2010 3:42:07 PM |

    I agree with Yoyo.  It seems to me this could be another red herring, like the dietary cholesterol nonsense.  Until they can tease apart whether the issue is due to dietary AGEs of the stuff produced from hyperglycemia then I don't necessarily see any reason to jump on an anti-meat bandwagon.

    Still, if you're truly concerned, invest in some Sous Vide equipment and cook your meat at low temperatures and don't finish it with a nice sear.

    I just read the Whitehall study, it really didn't show that CHD mortality increases from 83 mg/dL.  That's based on their mathematical extrapolation, which didn't fit the actual data very well at the lower range of blood glucose.  According to the data itself, CHD risk didn't begin increasing until 5.7 mmol/L, or 102 mg/dL.  

    That makes sense because 83 mg/dL is totally normal fasting glucose.

    2 things might help AGE's.
    I read that Carnosine which is a combo of 2 amino acids helps prevent glycation and many anti-aging experts recommend this supplement.
    Metformin reduces glucose production in the liver, reduces glucose absorption in the intestines and increases tissue sensitivity to actual glucose in the blood.
    Also may decrease cancer risk
    I have started these supplements in hopes of combating AGE's

    Another way to cook meat quickly is by using a pressure cooker. The 1.5-pound roast I'm having for dinner was done in 20 minutes--15 probably would have been fine. The package called for roasting it for four hours in the oven.

    A fasting glucose of 80-109 mg/dl was optimal for CVD and overall mortality in this paper.

    I've heard that Benfotiamine (200mg twice/day) is a potent AGE inhibitor.  I haven't been able to find much study on humans that backs up that claim though.

    Forgive my extreme ingnorance in this area, but how do meat and fats contain AGEs?

    A grilled steak? An egg fried in coconut oil? Where is the source of glucose here?

    "Fats and meats are the primary dietary source of AGEs..." I'm sorry, but this makes no sense to me... that fats and meats will increase blood sugar levels. My understanding to this point is that carbs are the cause, while good saturated fats and protein stabilize blood sugar levels.

    May I offer a little anecdotal evidence? After hearing a researcher from Australia's Baker Heart Institute describe how a low exogenous AGE diet appeared to reverse the complications of Type II Diabetes - although not Diabetic, I was intrigued enough to devise my own low-AGE regime.

    During the subsequent 5 months, with no attempt to restrict calories, I have lost nearly 15 kg, have had my total Cholesterol drop from 5.9 to 4.6, blood pressure drop from 128/88 to 110/62. Part of my strategy has been to avoid all sugars, including most fructose sources, in the interest of limiting endogenous AGE formation.

    BTW, I am 60 years (suddenly) young.

    Humans have been cooking meats, at least, 100,000 years before the invention of agriculture. The fact that it is so ubiquitous suggests that we are quite adapted to this even without thinner slices or smaller portions.

    Marinating meat with acid (vinegar) before grilling greatly reduces the maillard reaction and the formation of AGEs in meat.

    As we learn more about food, we learn more about the downsides: fish have mercury, meat has AGE's, carbs increase insulin sensitivity, etc. If you ask an expert what to eat, each one gives you a different answer.  How can we tell truth from belief?

    At what point is research like this going to limit the use of sugary glazes and marinades in meats and restaurant foods?

    Could adding spices and herbs reduce the bad effects of cooked meat. The study is small and funded by McCormick. Simple Addition to Meat Helps

    Just discovered this blog so forgive me if this has already been covered.  What about Neu5Gc?  Some recommend all mammal products be avoided as they all contain this substance and it sets up an inflammatory process in the body as humans do not have Neu5Gc and recognize it as foreign.  I  have recently been poking around at eating better (not that my past was bad!) and I have never been so confused in my entire life!!! Everyone has their own opinion and most of it is contradictory. High carb, low carb, no meat, more meat, more fish, all whole grains.  It's like a crap shoot.

    I don't have access to the original study, but the best one i could find has the food levels of AGEs reproduced with some comments at this gentleman's blog: http://inhumanexperiment.blogspot.com/2009/09/age-content-of-foods.html

    meat, even with low heat low pH preparations, seems to be high. eggs and legumes are low for their protein content.

    Yoyo, Joel--

    Much of the work on the AGE content of food, its absorption, and its consequences have been generated by Dr. Helen Vlassara's group in New York. The Japanese group Yoyo cites has, indeed, found some conflicting observations.

    I do not think that we can construct an "AGE-free" diet nor lifestyle, nor are the data on AGE-blockers sufficiently solid to justify taking them, in my view.

    However, this is such a fascinating line of research that I think it's worth being aware of and discussing.

    Bruce--

    Fascinating experience!

    How did you handle the AGE in meats issue?

    Marianne--

    Sorry, no insights into Neu5Gc.

    As I mentioned in the post, this is not a "no meat" comment. It is simply discussing the fascinating observations made by Helen Vlassara's group that, when taken as a whole, fit like a perfect puzzle piece into the question of why people with high blood sugars, e.g., diabetics and pre-diabetics, develop all the undesirable health effects they do.

    May I add a few more comments?

    Regarding meat, I have been eating normal and even generous portions - but I purchased a steamer and slow cooker to keep the cooking temps as low as possible. There is a limit in how far you can lower exogenous AGEs unless you adopt an extreme Raw regime.

    Then, your body will still produce its baseline of indogenous AGEs. I eat virtually zero sugar except for a minimal amount of fruit - usually 2 servings or 3 per day at most.

    We're really talking about a low Maillard Reaction Products diet, then I think. AGEs are many in type and the chemistry is complex. But there is good and growing evidence that the overall mix of MRPs are toxic. One study I read stated that lowering the exogenous AGE load by 40% reduces the circulating AGEs  by 60% and at this level, the body's own ability to scavenge out these compounds recovers.

    This suggests to me that we can tolerate MRPs up to a certain level, but the western diet is increasingly loading with these compounds. I wonder if this provides a (at least) partial explanation of the obestity epidemic.

    Food has been plentiful and cheap for at least 3 generations now, yet obesity is 'exploding' at the same time that the food industry is in an 'arms race' to heighten the marketability of their products.

    I wonder how calorie restriction affects AGEs.  Is this possibly how CR influences longevity?

    Hi Dr Davis
    I've hear from some diabetics how honey doesn't seem to affect them that bad.
    I looked arround and found some studies showing that honey after eaten for a while lowers blood sugar levels improiving liver function.
    Was wondering if you have an opinion related to honey

    So don't eat meat or carbs.  Good advice.
