Fish oil in the news



Hooray for the New York Times. They ran an article pointing out the miserable and inexcusable failure of American physicians to use fish oil after heart attack.

“It is clearly recommended in international guidelines,” said Dr. Massimo Santini, the hospital’s chief of cardiology, who added that it would be considered tantamount to malpractice in Italy to omit the drug.

...in the United States, heart attack victims are not generally given omega-3 fatty acids, even as they are routinely offered more expensive and invasive treatments, like pills to lower cholesterol or implantable defibrillators. Prescription fish oil, sold under the brand name Omacor, is not even approved by the Food and Drug Administration for use in heart patients."

The article focuses on the use of fish oil only after heart attack and doesn't tackle the larger issue of how fish oil is crucial for coronary disease in general. Of course, the article doesn't address the extraordinary effects of fish oil on lipoproteins, particularly triglyceride-containing varieties like VLDL and the postprandial (after-eating) intermediate-density lipoprotein (IDL).

It also talks about prescription fish oil and just glosses over fish oil as a nutritional supplement. I know of few reasons to use the prescription form. More than 90% of the time, nutritional sources of fish oil do the trick. (That is, fish oil capsule supplements, not just eating fish which doesn't provide enough for coronary plaque reduction or control.)

Occasionally, I'll meet someone who has a severe hypertriglyceridemia (very high triglycerides), or is a Apo E 2/2 homozygote (very rare). These special instances may, indeed, do better using prescription fish oil, since it is more concentrated--one prescription capsule providing the same omega-3 fatty acid content as three conventional capsules (1000 mg fish oil, 300 mg EPA+DHA).


But for most of us, the standard fish oil supplement you buy at the health food store or department store does just fine. If you read about the impurity of fish oil supplements (likely prompted by the manufacturer of Omacor, prescription fish oil), refer to the studies by Consumer Reports and Consumer Labs, both of which found no mercury or pesticide residues in dozens of fish oil preparations tested.

Look on the bright side. The conversation is growing. Fish oil, whether prescription or my favorite, Sam's Club Members' Mark brand, is a fabulously effective supplement with benefits that, in nearly all cases, exceeds the benefits of drugs.

Fish oil is an absolute requirement for your Track Your Plaque program and for you to hope to achieve control or reduction of your heart scan score.

Nutritional approaches to homocysteine reduction


For an in-depth discussion of nutritional approaches to homocysteine reduction, see my new article, Nutritional Therapies for Managing Homocysteine , in the most recent issue of Life Extension magazine. You'll find it at:

http://www.lef.org/magazine/mag2006/oct2006_report_homocysteine_01.htm

The report contains a detailed discussion of how to use foods to control homocysteine levels. Though I'm not a homocysteine-crazed fanatic like Life Extension publisher, William Falloon, I still there's some interesting aspects of homocysteine metabolism that need to be explored. I also think there's some genuine benefit to reducing homocystine, preferably with foods, secondarily with supplements.

Also see our recent update on homocysteine on the www.cureality.com website at:
http://www.cureality.com/library/fl_01-006homocysteine.asp

In the update, we tried to make sense of what the new studies on homocysteine treatment, NORVIT and HOPE-2, tell us in light of all the other studies on homocysteine that preceded them.

The American Heart Association diet guarantees you get heart disease!

Perhaps I stated that too strongly.

But the fact remains: the diet advocated by the American Heart Association is awful. The foods endorsed by their approach have no place on a list of healthy foods. Yes, you will find vegetables and fruits, etc.. But you will also find that the 2006 American Heart Association Diet and Lifestyle Recommendations dance around the issue of what foods to avoid. There's no explicit mention of how, for instance, common foods like Shredded Wheat cereal, ketchup, low-fat salad dressings, etc, among thousands of others, should be avoided.

No matter how you time your meals, mix them, combine proteins, fats, and carbohydrates, etc., you simply cannot squeeze health out of products like breakfast cereals, instant mashed potatoes, dried soup mixes, wheat crackers, etc. Yet these are the sorts of foods that are implicitly allowable in the Heart Association's diet program.

You can obtain a little insight into the motivations behind the diet design by looking at the Heart Association's Annual Report list of major supporters:

--ACH Food Companies--maker of Mazola margarine and corn oil. A contributor of between $500,000 and $999,000 to the Heart Association.

--ConAgra Foods--You know them as Chef BoyArdee, Peter Pan peanut butter, Kid Cuisine (pizza, macaroni and cheese). ConAgra contributed between $500,000 and $999,000 to the Heart Association.

--Archer Daniels Midland--Huge worldwide supplier of wheat flours, high-fructose corn syrup, and basic ingredients for manufacture of soft drinks, candies, and baked foods. ADM contributed between $1-4.9 million dollars to the American Heart Association.

Of course, the Heart Association provides many hugely positive services like funding research. But, on many official statements, you need to read between the lines. The Heart Association is funded by industry: medical device makers, drug makers, food manufacturers. Yes, some is contributed in the interest of health. But you can be sure that lots of money is also contributed in the hope of protecting specific commercial interests. Many of those decisions are made behind closed doors or on the golf course.

Be skeptical. Just because the Heart Association diet is a Casper Milquetoast version of a health program, it does not mean that you have to subscribe to their watered-down, politically correct, and downright useless nutrition recommendations.

I'm just right!

Ben is an energetic 45-year old entrepreneur. He started his own security alarm company and has, with tremendous hard work and long hours, built it into a successful local business. Despite his long hours, he found time to coach his son's football team and help with raising his 3 kids.

Ben's life took a detour when he had urgent bypass surgery at age 39. Just three years later, the chest pains and fatigue he'd experienced before bypass returned. Another heart catheterization revealed that all of his bypass grafts except one had closed. Three stents were implanted to salvage his original coronary arteries.

That's when I met Ben. Shockingly (perhaps I should know by now!), Ben was taking Lipitor and had been advised to follow a low-fat diet. That was the full extent of his heart disease prevention program. The burning question that I wanted answered was "Why did a 39-year old man have heart disease?".

Our analysis uncovered a smorgasbord of hidden patterns. You name it, Ben had it: postprandial (after-eating) patterns like IDL, low HDL, and, most notably, small LDL and lipoprotein(a). That's why Ben had heart disease as a 39-year old man--plain and simple.

We proceeded to correct all of his patterns. But the one aspect of his program that he struggled with: weight. At 5 ft 9 inches, Ben started at 285 lbs before bypass. He did manage to get to 270 after his surgery. I told him that, if he was going to get full control of his small LDL pattern, he needed to get to <210 lbs, perhaps even lower. Without substantial weight loss, he would never seize full control over coronary plaque.

Ben was satisfied that we had identified the hidden causes of his heart disease. But he remained skeptical that that magnitude of weight loss was necessary. Built like a football player, he looked stocky but not outright fat. He got down to 240 lbs but then he decided that he looked too skinny and just went right back up to 250-260 in weight.

At a weight of 250, this puts Ben's BMI (body mass index) at around 37, way over the cut-off of 30 for obesity. Now, the BMI can be misleading in people with larger frames and more muscle. But Ben undeniably had a generous abdomen, encasing the visceral fat that drives small LDL.

Unfortunately, Ben remained skeptical until I put three more stents into his right coronary artery last evening.

Small LDL is a powerful activator of lipoprotein(a). In other words, there's something peculiarly evil about the combination of small LDL and lipoprotein(a) that brings out the worst in both. You can't correct just one or the other. You've got to correct both. Don't learn this lesson the hard way.

I think (hope) that Ben is on track to get to around 200 lbs.

Prevention: Bad news in bits and pieces

Jan clearly did not want to talk about her heart scan. Her score of 502 came as a shock to her. After all, she'd survived breast cancer just a year earlier, having been through dozens of radiation treatments, chemotherapy, not the mention the emotional upheaval.

Now I was telling Jan that she had a very high heart scan score with a heart attack risk of 5% per year. Then we got to her lipoprotein patterns: Jan had several striking abnormalities, including a misleading LDL cholesterol that underestimated her true LDL by nearly 100% (LDL particle number), small LDL, and the dreaded lipoprotein(a).

"I can't handle this! Why did I get the stupid scan in the first place?!"

Giving her a chance to collect her emotions, I discussed how, even though this business can be frightening, it's far--FAR--better than the alternative: heart attack at 3 am, rush to the hospital, stents, bypass surgery, etc. Or, death for the >30% of people who don't make it to the hospital in time.

That's why I often tell people that prevention of disease is bad news in bits and pieces. But it's a lot more manageable this way. Coronary plaque is a controllable process. You don't have much control in the midst of a heart attack.

A second chance

Stewart had a CT heart scan in 2004. Score: 475.

As always in the Track Your Plaque program, Stewart had his lipoproteins assessed. Among his patterns were LDL 157 mg/dl, severe small LDL, and the (post-prandial, or after-eating) IDL. Stewart was also "pre-diabetic" with a blood sugar of 123 mg/dl. Blood pressure was also a major issue. Although initially concerned, life and distractions got in the way, and Stewart's attentions drifted away.

Two years of a lackadaisical effort and Stewart's heart scan score was 600, a 26% increase. Not as bad as it could have been doing nothing (i.e., 30% per year), but still far from great. But, even with the increase in score, we still really didn't get Stewart's attention. He went about his business with a very lax dietary program, overindulging in breads, crackers, goodies, hot dogs, etc., and following a virtually non-existent exercise program except for playing golf once or twice a week.

Unfortunately, Stewart started having pains in his chest with very minimal efforts like climbing a single flight of stairs. His stress test proved abnormal. Stewart then received a stent in his left anterior descending coronary and another in his circumflex. His right coronary artery had a 40-50% blockage, close to requiring a stent.

I stressed to Stewart that this had been preventable. Should motivation remain unchanged, the next step would be bypass surgery.

I think I finally succeeded in getting Stewart's attention. He found the prospect of a bypass operation a lot more concrete than the idea of progression or regression of coronary plaque. So Stewart is being given a second chance. Unfortunately, we will no longer be able to track Stewart's plaque very effectively, since two of three arteries now contain stents, and only the right coronary remains scorable.

I hope Stewart succeeds. But I sure wish he had done this earlier. He had realistic hopes of never requiring stents or bypass surgery.

Learn from Stewart's mistakes. Attention to your program requires vigilance. You can't ignore the causes of your coronary plaque for any length of time without it catching up to you. But seize your first and best chance.

Are you a skinny fat person?

AT 186 lbs. and 5 feet 10 inches, Doug did not regard himself as overweight. Sure, he had a little extra "love handles", a small bulge in the belly and a waist of 34 inches. But he was by no means fat, particularly compared to most of his friends, neighbors, and co-workers, many of whom were 50-100 lbs heavier.

But examine Doug's lipoprotein patterns and, if you didn't know what he looked like, you'd guess that he's at least 50 lbs or more overweight. His prominent patterns included low HDL, small LDL, high triglycerides, the after-eating IDL, and borderline high blood sugar of 116 mg/dl. His blood pressure usually ranged around 138/82.

In other words, Doug is among the 5-10% of people who have most of the features of the so-called "metabolic syndrome", but don't look the part. They usually (though not always) have a modest excess of visceral abdominal fat. While some people have to be 100 lbs overweight before they express these patterns, someone like Doug could do it with minimal excess weight, sometimes as little as 5-10 lbs.

Several specific genetic patterns can account for this exagerrated sensitivity to weight, but the solutions remain much the same. Heightened sensitivity to processed carbohydrates, particularly those containing wheat, is commonly present. A sharp reduction in processed carbohydrates like breads, breakfast cereals, and pretzels yields a huge benefit. Reduction in weight, of course, can also yield marked improvement in these patterns. This means that Doug should consider achieving his truly ideal weight of <175 lbs and become a truly skinny skinny person. Though his patterns might not be fully corrected, he will see substantial improvement across the board.

These patterns are also potent triggers for coronary plaque growth. Correction of low HDL, small LDL, etc. is crucial if you are to seize hold of your heart scan score.

Heart disease "reversal" gives health a bad name

Put the search phrase "reverse heart disease" into your internet search engine, and you'll uncover an astonishing range of sites, all making extravagant promises.

The treatment programs offered range from the bizarre (colonic irrigation, magnetism, etc.), to centers using conventional approaches like statin drugs and low-fat diets, to sites that make lofty predictions with few unique tools (slash the fat and heart disease dissolves).

95% or more of the sites you turn up are clearly pandering to the unknowing, the unsophisticated, the hopeless, or other helpless niche groups. Homeopathic preparations, chelation, magnical combinations of herbals, you name it, you'll find it attached to claims for heart disease reversal.

I've seen people use many of these treatments. Is there any effect on the rate of increase of the heart scan score? Do they impact on the 30% per year expected rate of increase? Absolutely not.

Unfortunately, this gives anyone practicing truly effective methods to reverse coronary plaque a bad name. Just associating with this suspect group of "practitioners" can make us look bad--guilt by association.

Whenever someone claims to have the secret of heart disease reversal, I ask "Can you prove it?" Show me some evidence. It doesn't necessarily have to be $30 million drug company sponsored study, but some evidence of effectiveness should be available. The only thing we should take on faith is our religion, not our health care.

Our growing number of people who have, indeed, reversed their heart scan scores--reversed heart disease--to me is persuasive evidence of the value of the Track Your Plaque approach. Not foolproof, not 100%, but the best damned approach I'm aware of, by a long shot.

Trans fats to be banned

Sometimes good may come from legislation.

The City of New York is contemplating a ban on trans-fat use by restaurants, bakeries, and other food establishments in preparation of their foods. (Trans-fats are also known as hydrogenated fats.)

At this point, I believe it's unclear, should this pass, what the response will be. If food preparers turn to butter, that's not much better. (Don't get fooled by the non-sensical argument of which is better, butter or margarine--they're both terrible.) Subtracting hydrogenated fats will no doubt cause major disruption of food preparation habits. It may even increase the cost of food slightly.



I believe that the true positive effect of this situation, however, will be the tremendously heightened awareness it will raise in the public, both in New York and elsewhere, on just how bad and pervasive trans-fats are. It may increase awareness that foods like donuts and pastries are not just about excessive quantities of sugars, but also trans-fat content.

If you're already a Track Your Plaque follower, you already know that the easiest way to dodge trans-fats in your diet is to minimize your use of processed foods--the cellophane-wrapped, pulverized, dried, just-add-water, microwavable and ready-to-eat foods that line supermarket shelves. Trans-fats are purely man-made. You won't find them--not a stitch--in green peppers, lettuce, olive oil, almonds. . .unprocessed foods. Watch for an in-depth report on trans-fats on the Track Your Plaque website in which we will detail the scientific evidence behind this movement, how to recognize when foods contain trans-fats, etc.

Back to basics!

Harold is energetic and highly motivated. His heart scan score of 997 really threw him for a loop: his view of himself as a healthy, slender, 58-year old clearly needed revision.

So Harold set himself on a quest to find new ways to help him deal with his heart disease risk. He enrolled in the Track Your Plaque program. Unfortunately, he skimmed through the information but didn't really put much of it to use.

Instead, he wanted the "secret" information that other people didn't know about, "insider" information that couldn't be found in magazines, wasn't know by doctors.

He'd read that hawthorne was useful for opening coronary arteries, so he bought hawthorne at the health food store. He read that coenzyme Q10 was a little know way to strengthen the heart, so he added that. A Chinese doctor in town was advertising chelation therapy that "dissolved plaque". He subscribed to a once-a-week intravenous infusion at the doctor's holistic clinic of Eastern medicine. He'd heard that testosterone opened up arteries, so he purchased a preparation of chrysin, horny goat weed, yohimbine, and saw palmetto. He was suspicious of many conventional medicines, but he didn't want to ignore his LDL cholesterol of 172 mg/dl. So he added guggulipid and a combination cholesterol-reducing product that contained about 10 ingredients.

Harold pursued his quest, often adding new agents that came with promising stories. One year later, Harold eagerly got another heart scan, certain that his extraordinary efforts were sure to yield a dramatic drop in his heart scan score. The score: 1372, a 37% increase.

Harold was therefore several thousand dollars poorer and several steps closer to taking the plunge, allowing a potentially fatal disease to cut his life short.

The message: There's no need to re-invent the wheel. There are no top-secret ways to reverse atherosclerotic plaque.


Don't neglect the basics. You can't do calculus until you learn how to add, subtract, and divide. From a heart scan score reducing perspective, achieving 60-60-60 in basic lipids, normalizing blood pressure and blood sugar, identifying any hidden lipoprotein patterns like small LDL and Lp(a), losing weight to your ideal weight, taking fish oil, normalizing vitamin D blood levels to 50-70 ng/ml--these are the necessary prerequisites to achieve control over your coronary plaque and stop the increase in your heart scan score.

You don't need to waste your time with the rants of some supplement-hawker eager to sell you the next cure for heart disease. I'm often amazed at the number of people who do so yet have never even taken care of someone with heart disease. Would you allow someone to try and repair your car if they've never actually laid their hands on an engine before? Then why would you entrust such a person with your health?

The Track Your Plaque approach is not fool-proof, but it's the best there is by a long shot.

Calling all super-duper weight losers!






Have you lost at least 1/2 your weight, e.g., 300 lbs down to 150 lbs? If you have, I have a major national magazine editor looking to talk to you.

If you have gone wheat-free and/or followed the dietary advice offered here in The Heart Scan Blog or through the Track Your Plaque program and would be willing to share your story, please let me know by commenting below. While losing half your body weight is not necessarily a requirement for health, it makes an incredibly inspiring story for others.

If we use your story, I will set aside a copy of my soon-to-be-released book, Wheat Belly.

Lp(a): Be patient with fish oil

High-dose omega-3 fatty acids from fish oil has become the number one strategy for reduction of lipoprotein(a), Lp(a), in the Track Your Plaque program for gaining control over coronary plaque and heart disease risk.

The original observations made in Tanzanian Bantus in the Lugalawa Study by Marcovina et al first suggested that higher dietary exposure to fish and perhaps omega-3 fatty acids from fish were associated with 40% lower levels of Lp(a). Interestingly, higher omega-3 exposure was also associated with having the longer apo(a) "tails" on Lp(a) molecules, a characteristic associated with more benign, less aggressive plaque-causing behavior.

Of course, the 600+ fish- consuming Bantus in the study consumed fish over a lifetime, from infancy on up through adulthood. So what is the time course of response if us non-Bantus take higher doses of fish oil to reduce Lp(a)?

We have been applying this approach in the Track Your Plaque program and in my office practice for the past few years. To my surprise, the majority of people taking 6000 mg per day of omega-3 fatty acids, EPA and DHA, will drop Lp(a) after one year.  Some have required two years.  Therefore checking Lp(a) after, say, 3 or 6 months, is nearly useless. (An early response does, however, appear to predict a very vigorous 1-2 year response.)

I'm sure that there is an insightful lesson to be learned from the incredibly slow response, but I don't currently know what it is.  But this strategy has become so powerful, despite its slow nature, that it has allowed many people to back down on niacin.

Baby your pancreas

There it is, sitting quietly tucked under your diaphragm, nestled beneath layers of stomach and intestines, doing its job of monitoring blood sugar, producing insulin, and secreting the digestive enzymes that allow you to convert a fried egg, tomato, or dill pickle into the components that compose you.

But, if you've lived the life of most Americans, your pancreas has had a hard life. Starting as a child, it was forced into the equivalent of hard labor by your eating carbohydrate-rich foods like Lucky Charms, Cocoa Puffs, Hoho's, Ding Dongs, Scooter Pies, and macaroni and cheese. Into adolescent years and college, it was whipped into subservient labor with pizza, beer, pretzels, and ramen noodles. As an adult, the USDA, Surgeon General's office and other assorted purveyors of nutritional advice urged us to cut our fat, cholesterol, and eat more "healthy whole grains"; you complied, exposing your overworked pancreas to keep up its relentless work pace, spewing out insulin to accommodate the endless flow of carbohydrate-rich foods.

So here we are, middle aged or so, with pancreases that are beaten, worn, hobbling around with a walker, heaving and gasping due to having lost 50% or more of its insulin-producing beta cells. If continued to be forced to work overtime, it will fail, breathing its last breath as you and your doctor come to its rescue with metformin, Actos, Januvia, shots of Byetta, and eventually insulin, all aimed at corralling the blood sugar that your failed pancreas was meant to contain.

What if you don't want to rescue your flagging pancreas with drugs? What if you want to salvage your poor, wrinkled, exhausted pancreas, eaking out whatever is left out of the few beta cells you have left?

Well, then, baby your pancreas. If this were a car with 90,000 miles on it, but you want it to last 100,000, then change the oil frequently, keep it tuned, and otherwise baby your car, not subjecting it to extremes and neglect to accelerate its demise. Same with your pancreas: Allow it to rest, not subjecting it to the extremes of insulin production required by carbohydrate consumption. Don't expose it to foods like wheat flour, cornstarch, oats, rice starch, potatoes, and sucrose that demand overtime and hard labor out of your poor pancreas. Go after the foods that allow your pancreas to sleep through a meal like eggs, spinach, cucumbers, olive oil, and walnuts. Give your pancreas a nice back massage and steer clear of "healthy whole grains," the nutritional equivalent of a 26-mile marathon. Pay your pancreas a compliment or two and allow it to have occasional vacations with a brief fast.

Bread equals sugar

Bread, gluten-free or gluten-containing, in terms of carbohydrate content, is equivalent to sugar.

Two slices of store-bought whole grain bread, such as the gluten-free bread I discussed in my last post, equals 5- 6 teaspoons of table sugar:








 

 

 

 

 

 

 

 

Some breads can contain up to twice this quantity, i.e., 10-12 teaspoons equivalent readily-digestible carbohydrate.

Gluten-free carbohydrate mania

Here's a typical gluten-free product, a whole grain bread mix. "Whole grain," of course, suggests high-fiber, high nutrient composition, and health.



 

 

 

 

 

 

 

 

What's it made of? Here's the ingredient list:
Cornstarch, Tapioca Starch, Whole Grain Sorghum Flour, Whole Grain Teff Flour, Whole Grain Amaranth Flour, Soy Fiber, Xanthan Gum, Soy Protein, Natural Cocoa and Ascorbic Acid

In other words, carbohydrate, carbohydrate, carbohydrate, carbohydrate and some other stuff. It means that a sandwich with two slices of bread provides around 42 grams net carbohydrates, enough to send your blood sugar skyward, not to mention trigger visceral fat formation, glycation, small LDL particles and triglycerides.

Take a look at the ingredients and nutrition facts on the label of any number of gluten-free products and you will see the same thing. Many also have proud low-fat claims.

This is how far wrong the gluten-free world has drifted: Trade the lack of gluten for a host of unhealthy effects.

Gluten-free is going DOWN

The majority of gluten-free foods are junk foods.

People with celiac disease experience intestinal destruction and a multitude of other inflammatory conditions due to an immune response gone haywire. The disease  is debilitating and can be fatal unless all gliadin/gluten sources are eliminated, such as wheat, barley, and rye.

A gluten-free food industry to provide foods minus gliadin/gluten has emerged, now large enough to become an important economic force. Even some Big Food companies are getting into the act, like Kraft, that now lists foods they consider gluten-free.

So we have gluten-free breads, cupcakes, scones, pretzels, breakfast cereals, crackers, bagels, muffins, pancake mixes and on and on. All are made with ingredients like brown rice flour, cornstarch, tapioca starch, and potato starch. Occasionally, they are made with amaranth, teff, or quinoa, other less popular, but gluten-free, grains.

Problem: These gluten-free ingredients, while lacking gliadin and gluten, make you fat and diabetic. They increase visceral fat, cause blood sugar to skyrocket higher than nearly all other foods (even higher than wheat, which is already pretty bad), trigger formation of small LDL and triglycerides, and are responsible for exaggerated postprandial (after-eating) lipoprotein distortions. They cause heart disease, cataracts, arthritis, and a wide range of other conditions, all driven by the extreme levels of glycation they generate.

Eliminating all things wheat from the diet is one of the most powerful health strategies I have ever witnessed. But replacing lost wheat with manufactured gluten-free foods is little better than replacing your poppyseed muffin with a bowl of jelly beans.

Whenever we've relied on the food industry to supply a solution, they've managed to bungle it. Saturated fat was replaced with hydrogenated fat and polyunsaturates; sucrose replaced with high-fructose corn syrup. Now, they are replacing wheat gluten-containing foods with junk carbohydrates.

For this reason, I am bringing out a line of recipes and foods that will be wheat gliadin/gluten-free, do NOT contain the junk carbohydrates that gluten-free foods are made of, and are genuinely healthy. They are tasty, to boot.

The gluten-free industry needs to smarten up. Having a following that is free of cramps and diarrhea but are obese, diabetic, and hobbling on arthritic knees and hips is good for nobody.

Medicine ain't what it used to be

The practice of medicine ain't what it used to be.

For instance:

White coats are out-of-date--Not only do they serve as filthy reservoirs of microorganisms (since they hang unwashed after repeated use week after week), they only serve to distance the practitioner from the patient, an outdated notion that should join electroshock therapy to treat homosexuality and other "disorders" in the museum of outdated medical practices.

Normal cholesterol panel . . . no heart disease?

I often hear this comment: "I have a normal cholesterol panel. So I have low risk for heart disease, right?"

While there's a germ of truth in the statement, there are many exceptions. Having "normal" cholesterol values is far from a guarantee that you won't drop over at your daughter's wedding or find yourself lying on a gurney at your nearest profit-center-for-health, aka hospital, heading for the cath lab.

Statistically, large populations do indeed show fewer heart attacks at the lower end of the curve for low total and  LDL cholesterol and the higher end of HDL. But that's on a population basis. When applied to a specific individual, population observations can fall apart. Heart attack can occur at the low risk end of the curve; no heart attack can occur at the high risk end of the curve.

First of all, to me a "normal" lipid panel is not adhering to the lax notion of "normal" specified in the lab's "reference range" drawn from population observations. Most labs, for instance, specify that an HDL cholesterol of 40 mg/dl or more and triglycerides of 150 mg/dl or less are in the normal ranges. However, heart disease can readily occur with normal values of, say, an HDL of 48 mg/dl and triglycerides of 125 mg/dl, both of which allow substantial small oxidation-prone LDL particles to develop. So "normal" may not be ideal or desirable. Look at any study comparing people with heart disease vs. those without, for instance: Typical HDLs in people with heart attacks are around 46 mg/dl, while HDLs in people without heart attacks typically average 48 mg/dl--there is nearly perfect overlap in the distribution curves.

There are also causes for heart disease that are not revealed by the lipid values. Lipoprotein(a), or Lp(a), is among the most important exceptions: You can have a heart attack, stroke, three stents or bypass surgery at age 40 even with spectacular lipid values if you have this genetically-determined condition. And it's not rare, since 11% of the population express it. How about people with the apo E2 genetic variation? These people tend to have normal fasting cholesterol values (if they have only one copy of E2, not two) but have extravagant abnormalities after they eat that contribute to risk. You won't know this from a standard cholesterol panel.

Vitamin D deficiency can be suggested by low HDL and omega-3 fatty acid deficiency suggested by higher triglycerides, but deficiencies of both can exist in severe degrees even with reasonably favorable ranges for both lipid values. Despite the recent inane comments by the Institute of Medicine committee, from what I've witnessed from replacing vitamin D to achieve serum 25-hydroxy vitamin D levels of 60-70 ng/ml, vitamin D deficiency is among the most powerful and correctable causes of heart disease I've ever seen. And, while greater quantities of omega-3 fatty acids from fish oil are associated with lower triglycerides, they are even better at reducing postprandial phenomena, i.e., the after-eating flood of lipoproteins like VLDL and chylomicron remnants, that underlie formation of much atherosclerotic plaque--but not revealed by fasting lipids.

I view standard cholesterol panels as the 1963 version of heart disease prediction. We've come a long way since then and we now have far better tools for prediction of heart attack. Yet the majority of physicians and the public still follow the outdated notion that a cholesterol panel is sufficient to predict your heart's future. Nostalgic, quaint perhaps, but as outdated as transistor radios and prime time acts on the Ed Sullivan show.

 

Idiot farm

The notion of genetic modification of foods and livestock is a contentious issue. The purposeful insertion or deletion of a gene into a plant or animal's genome to yield specific traits, such as herbicide resistance, nutritional composition, or size, prompted the Codex Alimentarius Commission, an international effort to regulate the safety of foods, to issue guidelines concerning genetically-modified foods.

The committee is aware of the concept of unintended effects, i.e., effects that were not part of the original gene insertion or deletion design. In their report, last updated in 2009, they state that:

Unintended effects can result from the random insertion of DNA sequences into the plant genome, which may cause disruption or silencing of existing genes, activation of silent genes, or modifications in the expression of existing genes. Unintended effects may also result in the formation of new or changed patterns of metabolites. For example, the expression of enzymes at high levels may give rise to secondary biochemical effects or changes in the regulation of metabolic pathways and/or altered levels of metabolites.

They make the point that food crops generated using techniques without genetic modification are released into the food supply without safety testing:

New varieties of corn, soybean, potatoes and other common food plants are evaluated by breeders for agronomic and phenotypic characteristics, but generally, foods derived from such new plant varieties are not subjected to the rigorous and extensive food safety testing procedures, including studies in animals, that are typical of chemicals, such as food additives or pesticide residues, that may be present in food.

In other words, conventional plant breeding techniques, such as hybridization, backcrossing, and introgression, practices that include crossing parental plants with their progeny over and over again or crossing a plant with an unrelated plant, yield unique plants that are not subject to any regulation. This means that unintended effects that arise are often not identified or tested. Plant geneticists know that, when one plant is crossed with another, approximately 5% of the genes in the offspring are unique to that plant and not present in either parent. It means that offspring may express new characteristics, such as unique gliadin or gluten proteins in wheat, not expressed in either parent and with new immunological potential in consuming humans.

Dr. James Maryanski, the FDA's Biotechnology Coordinator, stated during Congressional testimony in 1999 that:

The new gene splicing techniques are being used to achieve many of the same goals and improvements that plant breeders have sought through conventional methods. Today's techniques are different from their predecessors in two significant ways. First, they can be used with greater precision and allow for more complete characterization and, therefore, greater predictability about the qualities of the new variety. These techniques give scientists the ability to isolate genes and to introduce new traits into foods without simultaneously introducing many other undesirable traits, as may occur with traditional breeding. [Emphasis mine.]

Efforts by the Codex Alimentarius and FDA are meant to control the introduction and specify safety testing procedures for genetically modified foods. But both organizations have publicly stated that there is another larger problem that has not been addressed that predates genetic modification. In other words, conventional methods like hybridization techniques, the crossing of different strains of a crop or crossing two dissimilar plants (e.g., wheat with a wild grass) have been practiced for decades before genetic modification became possible. And it is still going on.

In other words, the potential hazards of hybridization, often taken to extremes, have essentially been ignored. Hybridized plants are introduced into the food supply with no question of human safety. While hybridization can yield what appear to be benign foods, such as the tangelo, a hybrid of tangerines and grapefruit, it can also yield plants containing extensive unintended effects. It means that unique immunological sequences can be generated. It might be a unique gliadin sequence in wheat or a unique lectin sequence in beans. None are tested prior to selling to humans. So the world frets over the potential dangers of genetic modification while, all along, the much larger hazard of hybridization techniques have been--and still are--going on.

Imagine we applied the hybridization techniques applied by plant geneticists to humans, mating an uncle with his niece, then having the uncle mate again with the offspring, repeating it over and over until some trait was fully expressed. Such extensive inbreeding was practiced in the 19th century German village of Dilsberg, what Mark Twain described as "a thriving and diligent idiot factory."

Eat triglycerides

Dietary fats, from olive oil to cocoa butter to beef tallow, are made of triglycerides.

Triglycerides are simply three ("tri-") fatty acids attached to a glycerol backbone. Glycerol is a simple 3-carbon molecule that readily binds fatty acids. Fatty acids, of course, can be saturated, polyunsaturated, and monounsaturated.

Once ingested, the action of the pancreatic enzyme, pancreatic lipase, along with bile acids secreted by the gallbladder, remove triglycerides from glycerol. Triglycerides pass through the intestinal wall and are "repackaged" into large complex triglyceride-rich (about 90% triglycerides) molecules called chylomicrons, which then pass into the lymphatic system, then to the bloodstream. The liver takes up chylomicrons, removes triglycerides which are then repackaged into triglyceride-rich very low-density lipoproteins (VLDL).

So eating triglycerides increases blood levels of triglycerides, repackaged as chylomicrons and VLDL.

Many physicians are frightened of dietary triglycerides, i.e, fats, for fear it will increase blood levels of triglycerides. It's true: Consuming triglycerides does indeed increase blood levels of triglycerides--but only a little bit. Following a fat-rich meal of, say, a 3-egg omelet with 2 tablespoons of olive oil and 2 oz whole milk mozzarella cheese (total 55 grams triglycerides), blood triglycerides will increase modestly. A typical response would be an increase from 60 mg/dl to 80 mg/dl--an increase, but quite small.

Counterintuitively, it's the foods that convert to triglycerides in the liver that send triglycerides up, not 20 mg/dl, but 200, 400, or 1000 mg/dl or more. What foods convert to triglycerides in the liver? Carbohydrates.

After swallowing a piece of multigrain bread, for instance, carbohydrates are released by salivary and gastric amylase, yielding glucose molecules. Glucose is rapidly absorbed through the intestinal tract and into the liver. The liver is magnificently efficient at storing carbohydrate calories by converting them to the body's principal currency of energy, triglycerides, via the process of de novo lipogenesis, the alchemy of converting glucose into triglycerides for storage. The effect is not immediate; it may require many hours for the liver to do its thing, increasing blood triglycerides many hours after the carbohydrate meal.

This explains why people who follow low-fat diets typically have high triglyceride levels--despite limited ingestion of triglycerides. When I cut my calories from fat to 10% or less--a very strict low-fat diet--my triglycerides are 350 mg/dl. When I slash my carbohydrates to 40-50 grams per day but ingest unlimited triglycerides like olive oil, raw nuts, whole milk cheese, fish oil and fish, etc., my triglycerides are 50 mg/dl.

Don't be afraid of triglycerides. But be very careful with the foods that convert to triglycerides: carbohydrates.
