Heart disease reversal is getting easier and easier

I've recently observed that more and more of our patients on the Track Your Plaque program seem to be stopping or reducing their heart scan scores. And they're doing it faster, in less time, and with larger drops in score.

I'm not entirely sure why the sudden surge in success. However, I do wonder if adding therapeutic levels of vitamin D--at least in our generally sun-deprived Wisconsin participants--is responsible. However, we've also gotten a lot smarter on how to correct the parameters that seems to have outsized effects on plaque growth, especially small LDL.

Yesterday alone, we had two people we added to our list of successes. One, an attorney, stopped his score in one year, with no change (compared to the expected increase of 30%). Another, a woman from the northeast, dropped her score 10% in one year. Her story is remarkable for beginning at a score >1000. In general, the higher your starting score, the longer it takes to stop or reduce it.

These are just two examples. It seems to be happening at an accelerating pace.

I can only hope that our surge in success (not 100%--yet!) will continue. But, every week, we're adding more and more people to our list of success stories.

A used car lot on every street corner

Imagine that, every day, a parade of used-car salesmen knock on your front door to sell you a special "deal". Day in, day out they knock, expecting you to hear about their offers openly.

Is there any doubt about their intentions or motives? Of course not. They're just trying to profit from selling you a car.

That's how it is in a medical office nowadays. Drug representatives, 5, 6, or more each and every day, promoting drugs. Except that the profits from drugs are far greater than a used automobile, and there's a third party involved in the transaction: you.

Today, a pushy representative came to my office. My staff and I tried to tell him that I was not interested in speaking to him. But he proved such a nuisance that I finally came out to tell him that I objected to the idea of drug reps just hanging around trying to hawk their wares.

He blurted, "Doctor, do you have patients with angina? Our new drug, ranolazine, is perfect. Forget about nitroglycerin, beta blockers, and all that. Here's the latest study proving it's better." He tried to shove a reprint of the study at me.

Getting to the bottom line, I asked, "What does it cost the patient?"

"Well, the co-pay is between $40 and $60. We're not yet well covered by insurance, so it'll cost patients around $200 a month."

Need I say more? Here's a drug that does little more than help relieve anginal chest pains. It doesn't reverse coronary plaque. It won't avoid heart attack, death, or procedures. It just modestly cuts back on the frequency of chest pain. And all for the cost of a single heart scan--a heart scan that could have prevented the entire cascade of symptoms/procedures/medication/hospitalization etc.

Hospitals, drug companies, medical device manufacturers. They're all businesses that thrive on your doctor's failure to detect and control your coronary plaque. Sometimes, even your doctor is part of this conspiracy to squeeze dollars out of human disease. Don't fall for it.

Heart disease reversal at age 77

I met Agnes 18 months ago after she underwent a heart scan that revealed a scary score of over 1100. Although in her mid-70s, this was still a very high score. (Recall that a score this high carries a risk for heart attack and death of 25% per year.) Poor Agnes was a wreck over this unexpected result. "I can't sleep, I can't stop thinking about it!"

She'd undergone the scan because her 44-year old son had a heart scan score of 2200! Unfortunately, he ended up with a bypass operation for very severe disease.

Despite having been seeing a cardiologist in Boston for the last 8 years for a murmur, we uncovered multiple hidden lipoprotein patterns, many of which she shared with her son. Her most notable abnormalities were a low HDL and small LDL. Nearly 100% of all LDL particles were, in fact, small. This pattern also caused her LDL cholesterol to be underestimated by over 40%.

18 months on the Track Your Plaque program and Agnes came into town to get a repeat scan. Her score was 10.2% lower. She'd learned to live with the idea that she had hidden heart disease missed by her doctor and cardiologist for many years. But knowledge of the substantial reversal she'd achieved in the 18 months on the program gave Agnes tremendous peace of mind.

Agnes left the office with a big smile.

If you need a reason to quit smoking...

If you've read Track Your Plaque, you already know my feelings about smoking and coronary plaque. Smoke, and you will lose the battle for control over coronary plaque growth--it will grow and grow until catastrophe strikes.

Nonetheless, this is not sufficiently motivating for some people.

If you need more motivation to quit smoking, just take a look at your heart scan sometime, accompanied by either one of the doctors or technicians at the scan center you choose. After you've had an opportunity to look at your coronary arteries, take a look at the lungs. The heart is in the middle and the lungs are the two large black areas on either side of the heart. (They're not really black; that's just the way the images are color-coded.)

Smokers will see large cavities in their lungs--literally, half-inch to one-inch wide holes that contain only air. Many of them. These represent remnants of lung tissue, digested away and now useless from the damage incurred through smoking.

Non-smokers should see uniform lung tissue without such cavities.

What surprised me early on in my heart scan experience was how little smoking exposure was required to generate these cavities. A 40-year old, for instance, who smoked a half-pack per day for 10 years would have them. Heavier smokers, of course, showed far more extensive cavities.

Officially, these cavities are called "emphysematous blebs", meaning the scars of the lung disease, emphysema.

When I've pointed out these cavities or emphysematous blebs to patients, 9 out of 10 times they immediately become non-smokers. Commonly, they'd exclaim, "I had no idea I was really damaging my lungs!" Most admitted that they were awaiting some bona fide evidence that they were truly doing some harm to their bodies. Well, that's it.

Give it a try if you're struggling.

Vitamin D for winter blues?

Winter is now over and spring is in the air, even in Wisconsin.

In this part of the country, winter blues are commonplace. Sometimes called Seasonal Affective Disorder (SAD) when it's severe enough to cause functional impairment, feelings of fatigue, lack of motivation, or the blues are very frequent when days are short and sunlight is in short supply.

I've been seeing many people in the last several weeks who were advised to add vitamin D to their program last fall. Christopher's experience was typical.

"You know, since you told me to take vitamin D, I didn't get sad and tired like I do every winter. This is the first time I can remember that happening. I didn't sleep as much and I didn't get that feeling of always being overwhelmed."

I've felt it myself this past winter. I think there's some real truth to this effect.

Dr. Bruce Hollis has published a small experience in treating people with SAD with vitamin D and showed measurable improvement in depression. (One recent study in older women failed to show any effect, however, when small doses of vitamin D of 800 units were administered. In my experience, this dose doesn't even come close to normalizing blood vitamin D levels.)

The best source for in-depth information on vitamin D is Dr. John Cannell's website, www.vitaminDcouncil.com. If you've read Dr. Cannell's discussion on the Track Your Plaque website, you know that he is an articulate spokesman for the benefits of vitamin D replacement. He also persuasively argues that vitamin D deficiency is rampant in northern climates and in people who don't get frequent sun exposure. Interestingly, we now have two studies of populations in Florida and one in Hawaii, both of which showed substantial percentages of people even in these tropical climates to be deficient in vitamin D (around 50% in Hawaii and 30% in Florida).

The dose we've used with much success is 2000 units per day in females, 3000 units per day in males. This yields normal blood levels of around 50 ng/dl in around 80-90% of people. Occasional people will require more, some less. The best way to do it is to check a baseline blood level and a level on therapy to determine the adequacy of your dose.

Dr. Cannell will tell you that it's very important to have your doctor check the right test: 25-OH-vitamin D3, not 1,25-diOH-vitamin D3. These are two very different tests of two different compounds.

In the Track Your Plaque program, we use vitamin D to reduce pre-diabetic tendencies, reduce blood pressure (vitamin D is an inhibitor of the pressure-raising hormone renin), shut down inflammation, and gain better control over coronary plaque (mechanism uncertain). In the process, you will sharply reduce risk of osteoporosis, colon and prostate cancer.

And maybe you'll be brighter when the winter blues come around again.

$4 per gallon gas is good for your health!

Gasoline is now approaching $4 per gallon in some parts of the U.S. But there's a silver lining in this dark cloud. In fact, I see this as a positive for your health.

How can higher gas prices possbily be good for health?

Imagine this trend continues: Fuel prices climb higher and higher. Driving your car will become increasingly more costly. What will be the fall-out?

Well, there will be a number of implications. But among the developments will be a broad impetus towards rejecting fuel-based sources of transportation. This may come as a shock to you, but humans legs were meant for walking!

Remember way back when, Mom would say "We need some milk"? In 1953, you wouldn't get in your car and zip to and from the supermarket. Instead, you would walk a quarter-mile, half-mile or more to the store. And you would carry your bags back. You might walk a mile or two to school and back. In 2006, this seems incomprehensible.

Higher fuel prices will prompt a gradual return to 1953--As transportation costs climb, your town may try and make it easier to walk as an alternative means of getting places.
Imagine that it was easy to walk three blocks to the grocery store, produce stand, work or school, walk along pleasant paths on the weekend, stroll to the home of friends. Drive or walk? Leave the car in the garage and save you and your family hundreds of dollars a month in gas bills.

In a few years, given the current fuel cost trends, there won't be a choice. But it will be in your favor for health.

Another Ornish casualty

Barry's lipoproteins were nearly all corrected to perfection: LDL 64 mg, HDL 57 mg, triglycerides 45 mg. He was approaching the Track Your Plaque goal of 60/60/60, the levels we find tip the scales heavily in your favor for achieving plaque reversal.

But one problem still prominently persisted: small LDL. Of Barry's 64 mg of total LSL, 90% of his LDL were small.

Barry was already on niacin (Slo-Niacin; Upsher Smith)1000 mg per day and fish oil, 4000 mg per day, both of which contribute to correction of this pattern. He had added occasional raw almonds and oat bran to his daily habits, both of which also help suppress small LDL. "I thought you told me that small LDL should go away if I did all this!" he lamented in frustration.

We probed Barry's diet choices more closely. "I eat really healthy foods, just like an Ornish program." Uh oh.

"What do you mean?" I asked.

"For breakfast, I have two slices of whole wheat toast--no butter or margarine, of course! I'll have Shredded Wheat with skim milk. That's it. My typical lunch is low-fat turkey--no mayonnaise!--on whole wheat. I'll add some low-fat whole wheat crackers or pretzels. That's pretty much my habit."

"How about dinner?"

"Dinner varies a lot. I'll usually have a low-fat meat like chicken or turkey, never beef, a vegetable, and a potato. I love rolls but I try to make them whole wheat. I don't use gravy. I love ice cream, so I've been having low-fat frozen yogurt instead. I guess that's about it."

Barry had indeed been counseled on how we approach nutrition. We, of course, do not endorse the low-fat approach of the Ornish program. Low saturated and hydrogenated fat, yes, but not the super-strict low-fat, "all fat is bad" approach of Dr. Dean Ornish.

Barry's diet is typical of someone on a low-fat restriction. When I asked him why he was eating this way, he admitted that he'd seen Dr. Ornish on a TV program in which he persuasively proclaimed that he reversed heart disease in his patients over the past nearly 20 years using this low-fat approach.

That explained it. Barry's nearly pure carbohydrate diet was triggering high blood sugar responses after meals, causing his insulin to skyrocket and magnifying the small LDL pattern.

I advised Barry to dramatically reduce his carbohydates like breads, pretzels, low-fat yogurt, crackers, etc. Instead, he could increase his lean proteins like eggs, egg whites, Egg Beaters, raw nuts and seeds, low-fat (yes, low-fat!) dairy products like yogurt and cottage cheese (both high protein), and healthy oils.

I've seen this happen with many people over the years: A severe low-fat restriction becomes a high-carbohydate diet. It's not uncommon for many people to have more than 70% of calories from carbohydrates on these programs.

The low-fat approach worked in the era of high-fat diets in the 1980s. In 2006, where convenience foods made with carbohydrates, especially wheat, predominate and pack 80% of supermarket shelves, low-fat is now a distorted nutritional mistake that leads to problems like Barry's uncontrolled small LDL, and often pre-diabetic or overt diabetes.

Should you take Plavix?

A question I get fairly frequently nowadays is, "Should I take Plavix?"

For the few of you who've managed to miss the mass advertising campaign for this drug on TV, USA Today, etc., Plavix is a platelet-blocking drug, known chemically as clopidogrel, that "thins" the blood and helps prevent blood clot formation in coronary arteries and carotid arteries, thus potentially reducing heart attack and stroke risk.

What if you have a heart scan score of, say, 450--should you take Plavix?

In general, no. First of all, aspirin and Plavix (generally taken together, since the effect of Plavix is incremental to that of aspirin) only block blood clot formation. They have no effect whatsoever on the rate of plaque growth. Aspirin and Plavix will neither slow it or increase it.

What they do is when a plaque ruptures like a little volcano and exposes its internal contents (inflammatory cells, fat, etc.--like a raw wound), a blood clot forms on top of the ruptured surface. If the clot is big enough, it can occlude the vessel and causes heart attack. Or, if it's a carotid artery, debris from the clot can break off and find its way headward to the artery controlling your speech or memory center. Aspirin and Plavix simply help inhibit clot formation once a plaque ruptures. That's it.

Interestingly, if you view any of Sanofi Aventis' commercials for Plavix, you'd think they came up with a cure for heart disease. It ain't true.

When is Plavix helpful? It's clearly an advantage after someone receives a coronary stent, drug-coated or uncoated;, after coronary bypass, particularly if certain metal punch devices are used to create the grafts in the aorta; and during and after heart attack. These are all situations in which blood clot formation is a forceful process. Blocking it helps.

In general, in asymptomatic people with positive heart scan scores at any level, we do not recommend taking Plavix. The Plavix people are extremely aggressive pushing their drug (hang around any medical office and see!) and, I believe, have gone overboard in promoting its benefits. Rarely, in someone with a very high heart scan score, say 2000 or more, we'll use Plavix for a period of a few months until lipids/lipoproteins and other risk measures are addressed, just as an added safety measure. But, in general, the great majority of people with some heart scan score or another do not receive it and I don't believe that they should.

As always, look beyond the marketing. The purpose of marketing is to increase profits, not to educate.

Dr. Ornish goofed

"I don't think I need the Track Your Plaque program. I've been doing the Ornish program, so I think that my plaque has already regressed."

So proclaimed Bruce, a recent patient I saw in consultation. Having suffered a heart attack three years earlier, he was thoroughly convinced that he was now cured following the Ornish program.


Indeed, back in the 1980s, many of us existed on greasy, high-fat diets of cheeseburgers, French fries, fried chicken, plenty of butter or margarine, mayonnaise, and the like.

Along came Dr. Dean Ornish, who wrote a book called "Dr. Dean Ornish's Program for Reversing Heart Disease: The Only System Scientifically Proven to Reverse Heart Disease Without Drugs or Surgery". This book struck a chord during this era and has been a hot-seller ever since it was published.

Does it work? In my experience, no, it does not.

Dr. Ornish claimed that sharply curtailing fat intake reverses heart disease. Closer to the truth is that, in people who start with high fat intakes, a low-fat restriction is indeed an improvement. This will lead to a modest improvement in blood flow in the coronary arteries due to a phenomenon called "endothelial dysfunction." This means that arteries will dilate modestly when specific changes are made. Thus, you will see minimal improvements in the measures he used (stress testing with nuclear imaging.)

What it does not mean is that plaque has regressed, certainly not "reversed".

In fact, our experience (over 10 years ago, when we first used the Ornish approach) was that the majaority of people did worse on this low-fat program: HDL dropped, triglycerides increased, blood sugar increased, inflammatory measures like C-reactive protein increased. Some people even magnified diabetic or pre-diabetic patterns.

It's almost certain that Bruce has not reversed his coronary plaque. In fact, I would bet that his plaque has grown substantially. Bruce started three years earlier from a diet high in unhealthy fats. If the expected rate of coronary plaque growth is 30% per year, perhaps he slowed it--to 20% or so. Since he didn't have a heart scan score at the time of his heart attack, we'll never know if he truly did reduce the quantity of coronary plaque he had.

But when I met him on his Ornish program, Bruce showed disturbing patterns that included an HDL cholesterol of 38 mg, 70% of all LDL particles were small, triglycerides measured 209 mg, and C-reactive protein was high at 2.8 mg/l. In other words, Bruce's plaque causes were far from corrected. Perhaps they were worse.

The Ornish program, despite it's ambitious claims, has outlived its usefulness. In 2006, it is an antiquated relic of a time past when lifestyle habits and technology were different.

Warning: This product may contain wheat!

Jerry experienced a peculiar sensation in his chest one evening while watching TV with his wife and kids. He squirmed in his chair and experienced a little breathelessness. But he kept it to himself and didn't say anything to his wife.

Fortunately, the feeling passed. But it concerned Jerry enough that he called a local heart scan center and scheduled a CT heart scan.* Minutes later, Jerry had a heart scan score of 112. At 46 years old, this placed him in the 90th percentile compared to other men in his age group.

Jerry came to my office for consultation. Among the first steps we took was to perform lipoprotein testing. Jerry showed striking abnormalities that included an HDL cholesterol of 38 mg, triglycerides of 210 mg, an unimpressive LDL of 133 mg but comprised of 99% small LDL, and excessive IDL (meaning that he was unable to clear dietary fats after eating).

At 5 feet 10 inches, Jerry weighed 190 lbs. He showed a slight excess bulge at the tummy, but hardly obese.

Jerry's history was remarkable, however, for the amount of carbohydrates he ate. "I'm addicted to bread. I love it! If I smell a loaf of fresh baked bread, I sometimes eat the whole loaf!"

Jerry also admitted to over-indulging in bagels (whole wheat), pretzels, low-fat snack chips, Raisin Bran cereal, Cheerios, and noodles. In fact, many days he'd have 5 or 6 servings of any of these foods. He also complained of an extraordinary amount of bowel gas and cramping. "Sometimes, I'm afraid to go to a group function. I might embarass myself."

I suggested an experiment: For a 4 week period, completely eliminate wheat-containing products--breads, pretzels, breakfast cereals, pasta, etc. In their place, increase intake of protein foods like eggs, raw almonds and walnuts, low-fat yogurt, cottage cheese, chicken, fish, and use healthy oils (olive, canola, grapeseed, flaxseed) more liberally.

Just four weeks later, Jerry came to the office a new man: 8 lbs lighter, brighter, with bursts of energy he hadn't had in years. And no gas!

Lesson: Wheat-based carbohydrates can be the culprit behind many lipoprotein patterns, especially low HDL, high triglycerides, small LDL, and others. Wheat can also be responsible for a myriad of abdominal symptoms, even joint pains and rashes. In its most extreme form, it's called "celiac disease". But experiences like Jerry's are quite common--not as obvious and dramatic as full-blown celliac disease, but smouldering and destructive, nonetheless.

Track Your Plaque expert, Dr. Loren Cordain of Colorado State University, tells us that, in his reconstruction of the history of human illness, there was an extraodinary surge in disease just about the time when humans began cultivating wheat around 8000 B.C. (Track Your Plaque members: Read Dr. Cordain's fascinating interview at http://www.cureality.com/library/fl_04-005cordaininterview.asp.)

Do you need to eliminate wheat products entirely from your diet? It's something to think about, particularly if you share any of the difficulties that Jerry had.


*In general, I do not recommend heart scanning as a self-prescribed tool for chest pain or other symptoms. Symptoms should always be discussed with your doctor.
Diabetes from fruit

Diabetes from fruit

Mitch sat in my office, looking much the same as he had on prior visits.

At 5 ft 7 inches, he weighed a comfortable 159 lb, though he did have a small visible "paunch" above his beltline.

I had been seeing Mitch for his heart scan score of 1157 caused by low HDL of 38 mg/dl, severe small LDL (87% of total LDL), and lipoprotein (a).

Part of Mitch's therapeutic program was elimination of wheat, cornstarch, and sugars, the three most flagrant triggers of small LDL particles, and weighing his diet in favor of oils and fats to reduce Lp(a). However, Mitch somehow failed to follow our restriction on fruit, which we limit to no more than two 4 oz servings per day, preferably berries. He thought we said "Eat all the fruit you want." And so he did.

Mitch had a banana, orange, and blueberries for breakfast. For lunch, along with some tuna or soup, he'd typically have half a melon, a pear, and red grapes. For snacks, he'd have an apple or nectarine. After dinner, it wasn't unusual for Mitch to have another piece of fruit for dessert.

Up until Mitch's last visit, he'd had blood glucose levels of 100-112 mg/dl, above normal and reflecting mild insulin resistance and pre-diabetes. Today, on his unlimited fruit diet, his blood sugar: 166 mg/dl--well into diabetes territory.

I helped Mitch understand the principles of our diet better and advised him to reduce his fruit intake to no more than the 2 small servings per day, as well as sticking to our "no wheat, no cornstarch, no sugar" principles.

While fruit is certainly better than, say, a half-cup of gummy bears (84.06 g carbohydrates, 50.12 g sugars), fruit is unavoidably high in carbohydrates and sugars.

Take a look at the carbohydrate content of some common fruits:

Apple, 1 medium (2-3/4" dia)
19.06 g carbohydrate (14.34 g sugar)

Banana, 1 medium (7" to 7-7/8" long)
26.95 g carbohydrate (14.43 g sugar)

Grapes, 1 cup
27.33 g carbohydrate (23.37 g sugar)

Pear, 1 medium
25.66 g carbohydrate (16.27 g sugar)

Source: USDA Food and Nutrient Database

Fruit has many healthy components, of course, such as fiber, flavonoids, and vitamin C. But it also comes with plenty of sugar. This is especially true of modern fruit, the sort that has been cultivated, hybridized, fertilized, gassed, etc. for size and sugar content.

When you hear such conventional advice like "eat plenty of fruits and vegetables," you should hear instead: "eat plenty of vegetables. Eat a small quantity of fruit."

    I agree. No matter how many times I attempt to make fruit a regular part of my diet, it always has a negative impact. At first I feel it as tooth pain. Then it seems to awaken a demon of sugar cravings.

    Getting fruit out of my diet, and more importantly - juice and refined sugar, has had the greatest impact on not only my health, but the health of my girlfriend and family members as well.  There's a huge difference between a little sugar and no sugar.

    But it has nothing to do with the carbohydrate content. Currently I'm eating at least 200 grams of starch per day, and am far healthier doing so than I was on a low-carb, high-fat diet. Have had fasting blood sugars dip all the way down to 67 on such fare.  

    One thing is for sure though. The fructose/fat combo. will give you the greatest chance to add body fat and raise your blood sugars of any other combination.  Tougher to do with fruit, but very easy to do chugging juice or soda with a mixed meal.  Like Richard J. Johnson, fructose researcher says, it is both a quantity and a speed of ingestion issue (speed of fructose ingestion that is, not of blood sugar rise, which is less significant).

    I do miss my fruits. The glucometer came in handy in helping me figure out how much fruit I could eat - 1/4 of an apple, 1-2 grapes, a couple of berries....that is it. Funny thing happened when I gave up high carb foods: vegetable started tasting sweeter.

    Dr. Richard Bernstein, who wrote Diabetes Solution, says he does not recommend any fruit and he has not eaten fruit in 40 years. He says one can get the same nutrients found in fruits from the low carb vegetables he recommends.

    The odd thing about fructose is that it does NOT increase blood sugar like glucose, sucrose, or more "complex" carbohydrates, but exerts a substantial delayed effect on insulin resistance, increased triglycerides, and postprandial abnormalities.

  • Simon

    2/2/2010 4:17:57 PM |

    Dr. Davis (and Matt for that matter),

    Would you suggest, if someone is fairly carbohydrate tolerant, that they actually eat there carbohydrates from properly prepared non glutenous grains or starchy vegetables rather than exceed two servings of fruit a day? Rice and quinoa etc have not gotten such a great rap, as they are not as nutritionally dense, but it seems that in light of what we know about fructose they may just be better none the less.

    Best,

    Interesting story, very interesting. Many of us have heard the concerns raised by the high-fructose corn syrup on heart disease and diabetes but this is the first Ive seen or at least grabbed my attention on the subject.
    Just wondering if he had any daily exercise routine to increase insulin sensitivity and ward off the blood sugar problems.
    I wholeheartedly agree with limiting fruit, although I must admit I had a half of cup of gummi bears last night (but heck, I did 2.5 hours @ 15% grade,3.5 mph yesterday) so I didnt feel like fighting the craving too much Smile
    Normally high protein to aid in recovery from strengthtraining portion of my routine but on rare occasions...
    Anyways, I would think this couldve been avoided with exercise on Mitch's part and he could get away with going bananas with the bananas.
    So what's the plan now? Give him some metformin and tell him to walk an hour a day?

    Stumbled upon this blog last night, great what Ive read so far, I think I was researching how many calories are used vs. how many are excreted in feces and your almond post came up. I bookmarked your blog.
    Cheers

    I would be curious to hear if we have any understanding of the mechanism that induced your patient's change in blood sugar. As you point out, fructose does not raise blood glucose.  If that's the case, and if wheat -- which he cut out -- does raise blood glucose, how would eating more fruit do more damage to insulin response and fasting glucose levels than the wheat that was eliminated?

    This is very interesting!

    Hear, hear!  I used to be a fruit junkie; it seemed like a healthy way to satisfy my perpetual cravings for sugar.  When I switched to a paleo diet, my consumption of fruit gradually declined.  Now I'd prefer brussels spouts braised in cream to a banana, hands down.  Anything more than a small serving or two of berries per week seems excessive.

    Nature's junkfood, indeed!

    Europeans have had fruit as a part of their diet for quite a long time.  In winter they might have only had preserves or maybe no fruit at all, but when it was available, I'm sure they gorged on it and did not suffer from diabetes because of it.  Perhaps something, like Vitamin D deficiency, as you have mentioned before, could lead to his insulin resistance and inability to tolerate too much fruit?

    I am an ex-fruit junkie as well. For the first time in the last 5 yrs, I'm finally losing fat. I used to eat fruit everyday 2-4 servings. Now I eat 2-4 servings a week. I pick the lower sugar ones now too.

    My husband is diabetic and I've successfully got him and our sons off of sugar(I just refused to buy any more). But I do buy fruit and honey, for the kids. But my husband continues to use both! I hope I can twist his arm into reading this post. If he would just check his blood sugar levels more consistently I'm sure he could still eat a little fruit. His favorite starch is potatoes, baked potatoes, which don't effect his sugar levels as much. I'm trying to use the potatoes to get him off the breads.

    Dr. Davis, If I may ask, what types of seeds do you consume?

    I considered sunflower or pumpkin seeds, but was put off my their omega 6 profile. Would eating either type of seeds negatively affect one's w3-w6 ratio?

    What about avocados, tomatoes, olives and lemons?

    All great. While I don't think that we should weigh our diets in favor of polyunsaturates (omega-6), I believe that seeds, on the whole, are beneficial, as are avocados, olives, etc.

    Hi
    I've read in some places that a glucose spike after an intense workout is ok and that it helps build muscle.
    What's your opinion on this?

    Mitch messed things up completely regarding your fruit instructions. Do you think that he may have messed up anything else in his diet?

    People who follow Doug Graham's 80-10-10 (carbs-fat-protein) predominantly fruitarian diet claim it's an ideal diet and that all that sugar isn't a problem as long as fat intake is very low. Is there any science to back that up?

    While it's interesting to read various point's of view of the percieved 'dangers of fruit' I also am noticing that there is very little in this article and it's associated comments that is anything more than opinion or worse yet, other people's opinions.

    If you were stuck on a deserted island, you would be eating whatever you could get your hands BUT you would be eating foods as nature intended them.  Coconut, seafood, wild game, and if you were lucky enough fruits, berries etc.

    Keep it natural.  If you can't find it nature, don't eat it.  Most people frown on fruit while still consuming a diet high in refined white flours, sugars, salts and more recently soy foods.  It is these foods that are destabilising your body's response to insulin spikes.

    Mitch did not have the problems because of the fruit, but because of the fat in the diet.
    Fat blocks insulin from working. If you eat diet high in sugars, as most of us do, you have to limit your fat to less than 10% of your calorie intake.

    I believe the answers are so simple, but we are not seeing. Just look at the animals - they are either meat eaters or plant eaters. If there is any "cross over", it is very limited, e.g. eating an insect with a plant.

    We are really not supposed to mix these foods a lot, but we all do.

    When you hear such conventional advice like "eat plenty of fruits and vegetables," you should hear instead: "eat plenty of vegetables. Eat a small quantity of fruit."  AND IN "IF YOU STILL EAT >10% FAT".  By now you know its the fat that makes you insulin resistant.  If you eat low fat and you still have issues, it ain't dietary diabetes.  Please get the facts correct.

    Mitch had a banana, orange, and blueberries for breakfast. For lunch, along with some tuna or soup, he'd typically have half a melon, a pear, and red grapes. For snacks, he'd have an apple or nectarine. After dinner, it wasn't unusual for Mitch to have another piece of fruit for dessert.

    It sounds like you're creating problems yourself by trying to solve this issue instead of looking at why their is a problem in the first place.

    The diabetic patients are always wary of eating fruits as they contain sugar.They are always avoiding them...how sad that they can not derive the benefits of vitamins which they need ion the body.

    People with diabetes can eat any kind of fruit, regardless of the sugar content. Everyone is encouraged to eat at least five portions of fruit and vegetables every day. Spreading the fruit you eat through the day will avoid a sudden rise in blood glucose levels.Generic Actos is the right cure if one is suffering from diabetes.
    All fruit and vegetables are extremely good for you. They are high in fibre, low in fat and packed with vitamins and minerals. Research has shown that eating more can reduce the risk of coronary heart disease, some cancers and some gut problems. So i think don't avoid fruits, and if you blame fruits then you must have to blame the rest of your diet. Well is a coke is good for your health then?lols.. What you say?

    The odd thing about fructose is that it does NOT increase blood sugar like glucose, sucrose, or more "complex" carbohydrates, but exerts a substantial delayed effect on insulin resistance, increased triglycerides, and postprandial abnormalities.

    Would some of you commenters like to go to the vegan "all fruit diet" boards and kindly comment?  You seem way more informed about the medical / dietary science behind fruit than those folks.  They''re under the impression that the reason blood sugars rise from eating fruit is b/c you''re combining it with protein/fat meals.  They say ... fat clogs insulin receptors (I''m not making this up) ... so, eating fruit with fat just causes blood sugar levels to rise and requires more insulin to get produced to get it under control.  There''s a current trend for vegans to try this Hippocrates diet or 80-10-10 diet, 80% carbs, 10% prot, 10% fat.  Eating raw is good, if it''s raw veggies, +fish proteins and fat.  But, most vegans don''t do the strict healthy stuff, instead opting for the tastiest stuff: fruit.  So, some go on these nothing-but-fruit diets, eg: 30 bananas a day.  They binge eat on fruit until they''re bloated, then wash-rinse-repeat several times a day.  Some folks have high insulin sensitivity, so they can get away with it.  But, others don''t seem to understand that just b/c it works for someone else doesn''t mean it''ll work for you.  All the sugars get burned up, then they get moody when they have a crash and have to force-feed more fruit into their system.  I just get a kick out of reading their forums, where folks seem to have this bizarre pseudo-science mentality vs. folks here that seem to have actually read and understood actual science about diet & nutrition.
