High blood pressure vanquished

Heart Scan Blog reader, Eric, related his blood pressure success story to me:

I'm 34 and have been battling chronic hypertension (systolic 150-200, depending on my anxiety levels) even with multiple prescriptions for over a decade now. I've seen four different cardiologists, all stumped as to what is causing my hypertension. First, they suspected coarctation of my aorta [a constriction in the aorta], but an angiogram determined blood pressure readings were the same on both sides of the narrowing.

The second angiogram performed last year to determine if my coarct had worsened determined that it had not, but that my aorta had calcium build up. The cardiologist was stumped because he told me he hasn't seen calcium in a patient so young. Needless to say, this scared me to death, with my wife being pregnant with our first child. I asked if it could be reversed and he didn't know so he sent me to get a Berkeley lab.

The Berkeley came back with LDL 91, HDL 41, Triglycerides 73, CRP 4.1, vit D 26. The doctors weren't very knowledgeable about explaining to me what these meant and how I could correct the low vit D and high CRP. They told me to follow the low-fat diet recommended by Berkeley. Well I've already tried the DASH diet and didn't like how I felt or my energy levels, so I didn't transition.

I was at a loss until I encountered your blog and it was truly a gift. It was a refreshing feeling to meet a knowledgeable Dr. who knew what I was going through and seems to truly care about reversing calcium in the heart (something I never got from my any of my cardiologists). With your blog I have an appointment to get a heart scan here in CO and take that number along with my Berkeley results and join Track Your Plaque.

For the past 2 weeks I've been following your advice by taking a D3+K2 supplement with Omega3 Fish oil and avoiding all grain, wheat, sugar and I'm already down 4lbs to 223.5lbs at 6'5" tall and my blood pressure readings have been 128/54 and 129/60 the past 2 days! With your help I may not have the dark future my father had: dead at 48 with a massive heart attack.

Stay on the look out because I look forward to telling you how I'm one of your top calcium losers!

Conventional medical care fails at so many levels for so many people. While Eric's doctors were busy contemplating the next angiogram, they were neglecting several crucial aspects of his health.

It's really not that tough. But it can mean doing the opposite of what conventional "wisdom" tell us.

DHEA and Lp(a)

DHEA supplementation is among my favorite ways to deal with the often-difficult lipoprotein(a), Lp(a).

DHEA is a testosterone-like adrenal hormone that declines with age, such that a typical 70-year old has blood levels around 10% that of a youthful person. DHEA is responsible for physical vigor, strength, libido, and stamina. It also keeps a lid on Lp(a).

While the effect is modest, DHEA is among the most consistent for obtaining reductions in Lp(a). A typical response would be a drop in Lp(a) from 200 nmol/L to 180 nmol/L, or 50 mg/dl to 42 mg/dl--not big responses, but very consistent responses. While there are plenty of non-responders to, say, testosterone (males), DHEA somehow escapes this inconsistency.

Rarely will DHEA be sufficient as a sole treatment for increased Lp(a), however. It is more helpful as an adjunct, e.g., to high-dose fish oil (now our number one strategy for Lp(a) control in the Track Your Plaque program), or niacin.

Because the "usual" 50 mg dose makes a lot of people bossy and aggressive, I now advise people to start with 10 mg. We then increase gradually over time to higher doses, provided the edginess and bossiness don't creep out.

The data documenting the Lp(a)-reducing effect of DHEA are limited, such as this University of Pennsylvania study, but in my real life experience in over 300 people with Lp(a), I can tell you it works.

And don't be scared by the horror stories of 10+ years ago when DHEA was thought to be a "fountain of youth," prompting some to take megadose DHEA of 1000-3000 mg per day. Like any hormone taken in supraphysiologic doses, weird stuff happens. In the case of DHEA, people become hyperaggressive, women grow mustaches and develop deep voices. DHEA doses used for Lp(a) are physiologic doses within the range ordinarily experienced by youthful humans.

No more cookies

Jeanne enjoyed her Christmas holidays. She especially liked sharing the cookies she made for her grandchildren, sneaking 2 or 3 every day over a couple of weeks. On top of this, she enjoyed the Christmas candy, egg nog, leftover stuffing and cranberry sauce, topped off with a night of nutritional debauchery on New Year's Eve.

Lipid panel in October:

Total cholesterol 146 mg/dl
LDL cholesterol 72 mg/dl
HDL cholesterol 64 mg/dl
Triglycerides 49 mg/dl

Lipid panel in early January:

Total cholesterol 229 mg/dl
LDL cholesterol 141 mg/dl
HDL cholesterol 59 mg/dl
Triglycerides 147 mg/dl


I call the holidays The Annual Wheat and Sugar Frenzy. It's the carbohydrates, especially those from products made of wheat and sucrose, that caused the marked shifts in Jeanne's lipid patterns. Let's take each parameter apart:

--Triglycerides go up due to de novo lipogenesis, liver conversion of carbohydrates into triglycerides. Triglycerides enter the bloodstream as VLDL particles which, in turn, interact with LDL and HDL.

--LDL goes up because carbohydrate exposure increases VLDL, followed by conversion to LDL. The triglyceride-rich LDL created is converted to small LDL particles. Had we measured small LDL changes in Jeanne, we likely would have measured something like an increase (by NMR) from 800 nmol/L to 1600 nmol/L, a carbohydrate effect.

--The increased VLDL also makes HDL triglyceride-rich, cause more rapid degradation of HDL particles. (It also makes them smaller, like LDL.) Given sufficient time (a few more months), HDL would drop into the 40's.

--Total cholesterol changes reflect the composite of the above numbers. (Total cholesterol = LDL cholesterol + HDL cholesterol + Trig/5) (Note that, as HDL drops, so will total cholesterol; that's why this value is worthless and should be ignored.)

So don't be surprised by the above distortions after a period of carbohydrate indulgence. Although your unwitting primary care doc will see such changes as opportunity for Lipitor, it is nothing more than the cascade of effects from a carbohydrate-driven distortion of lipoproteins.

How to become diabetic in 5 easy steps

If you would like to become diabetic in as short a time as possible, or if you have someone you don't like--ex-spouse, nasty neighbor, cranky mother-in-law--whose health you'd like to booby trap, then here's an easy-to-follow 5-step plan to make you or your target diabetic.


1) Cut your fat and eat healthy, whole grains--Yes, reduce satiety-inducing foods and replace the calories with appetite-increasing foods, such as whole grain bread, that skyrocket blood sugar higher than a candy bar.

2) Consume one or more servings of juice or soda per day--The fructose from the sucrose or high-fructose corn syrup will grow visceral fat and cultivate resistance to insulin.

3) Follow the Institute of Medicine's advice on vitamin D--Take no more than 600 units vitamin D per day. This will allow abnormal levels of insulin resistance to persist, driving up blood sugar, grow visceral fat, and allow abnormal inflammatory phenomena to persist.

4) Have a bowl of oatmeal or oat cereal every morning--Because oat products skyrocket blood sugar, the repeated high sugars will damage the pancreatic beta cells ("glucose toxicity"), eventually impairing pancreatic insulin production. (Entice your target even further: "Would you like a little honey with your oatmeal?") To make your diabetes-creating breakfast concoction even more effective, make the oatmeal using bottled water. Many popular bottled waters, like Coca Cola's Dasani or Pepsi's Aquafina, are filtered waters. This means they are devoid of magnesium, a mineral important for regulating insulin responses.

5) Take a diuretic (like hydrochlorothiazide, or HCTZ) or beta blocker (like metoprolol or atenolol) for blood pressure--Likelihood of diabetes increases 30% with these common blood pressure agents.

There you have it! Perhaps we should assemble a convenient do-it-yourself-at-home diabetes kit to help, complete with several servings of whole grain bread, a big bottle of cranberry juice, some 600 unit vitamin D tablets, a container of Irish oatmeal, and some nice bottled water.

Restaurant eating: A fructose landmine

There is no remaining question that fructose is among the worst possible things humans can consume.

Followers of the Heart Scan Blog already know this, from conversations like The LDL-Fructose Disconnect, Where do you find fructose?, and Goodbye, fructose.

But fructose, usually as either high-fructose corn syrup (44%, 55%, occasionally higher percentage fructose) or sucrose (50% fructose), is ubiquitous. I've seen it in the most improbable places, including cole slaw, mustard, and dill pickles.

It's reasonably straightforward to avoid or minimize fructose exposure while eating at home, provided you check labels and focus on foods that don't require labels (like green peppers, salmon, and olive oil, i.e., unprocessed foods). But when you choose to eat at a restaurant, then all hell can break loose and fructose exposure can explode.

So what are some common and unsuspected fructose sources when eating at a restaurant?

Salad dressings--Dressings in all stripes and flavors are now made with high-fructose corn syrup and/or sucrose. This is especially true of low-fat, non-fat, or "lite" dressings, meaning oils have been replaced by high-fructose corn syrup. It can also be true of traditional non-low-fat dressings, too, since high-fructose corn syrup is just plain cheap.

Olive oil and vinegar are still your safest bets. I will often use salsa as a dressing, which works well.

Sauces and gravies--Not only can sauces be thickened with cornstarch, many pre-mixed sauces are also made with high-fructose corn syrup or sweetened with sucrose. Barbecue sauce is a particular landmine, since it is now a rare barbecue sauce not made with high-fructose corn syrup as the first or second ingredient. Sauces for dipping are nearly always high-fructose corn syrup-based.

Ketchup--Yup. Good old ketchup even is now made with high-fructose corn syrup. In fact, you should be suspicious of any condiment.

Highball, Bloody Mary, Margarita, Daiquiri, beer--Even the before-dinner or dinner drink can have plenty of fructose, particularly if a mix is used to make it. While Blood Marys seem the most benign of all, adorned with celery, pickle, and olive, just take a look at the ingredient label on the mix used: high-fructose corn syrup.

Fructose is a stealth poison: It doesn't immediately increase blood sugar; it doesn't trigger any perceptible effect like increased energy or sleepiness. But it is responsible for an incredible amount of the health struggles in the U.S., from obesity, to diabetes, to hyperlipidemias and heart disease, to arthritis, to cataracts.

A glycation rock and a hard place

Advanced Glycation End-products, or AGEs, the stuff of aging that mucks up brains, kidneys, and arteries, develop via two different routes: endogenous (from within the body) and exogenous (from outside the body).

Endogenous AGEs develop via glycation. Glycation of proteins in the body occurs when there are glucose excursions above normal. For instance, a blood glucose of 150 mg/dl after your bowl of stone-ground oatmeal causes glycation of proteins left and right, from the proteins in the lens of your eyes (cataracts), to the proteins in your kidneys (proteinuria and kidney dysfunction), to skin cells (wrinkles), to cartilage (brittle cartilage followed by arthritis), to LDL particles, especially small LDL particles (atherosclerosis).

At what blood sugar level does glycation occur? It occurs even at "normal" glucose levels below 100 mg/dl (with measurable long-term cardiovascular effects as low as 83 mg/dl). In other words, some level of glycation proceeds even at blood glucose levels regarded as normal.

There's nothing we can do about the low-level of glycation that occurs at low blood sugar levels of, say, 90 mg/dl or less. However, we can indeed do a lot to not allow glycation to proceed more rapidly, as it inevitably will at blood sugar levels higher than 90 mg/dl.

How do you keep blood sugars below 90 mg/dl to prevent excessive glycation? Avoid or minimize the foods that cause such rises in blood sugar: carbohydrates.

What food increases blood sugar higher than nearly all other known foods? Wheat.

Is einkorn the answer?

People ask: "What if I would like a piece of bread or other baked product just once in a while? What is safe?"

Eli Rogosa, Director of The Heritage Wheat Conservancy, believes that a return to the wheat of our ancestors in the Fertile Crescent, circa 10,000 years ago, is the answer.

Former science teacher, now organic farmer, farm researcher, and advocate of sustainable agriculture, Eli has been reviving "heritage" crops farmed under organic conditions, some of her research USDA-funded.

In particular, Eli has been cultivating original 14-chromosome ("diploid") einkorn wheat. Although einkorn contains gluten (in lesser quantities despite the higher total protein content), the group of proteins that trigger the immune abnormalities of celiac disease and other immune phenomena, Eli tells me that she has witnessed many people with a variety of wheat intolerances, including celiac disease, tolerate foods made with einkorn wheat. (The variety of glutens in einkorn differ from the glutens of the dwarf mutant that now dominate supermarket shelves.)

Eli travels to Israel every year, returning with "heritage" seeds for wheat and other crops. She formerly worked in the Israel GenBank as Director of the Ancient Wheat Program. She has written a brochure that describes her einkorn wheat.

Eli sent me 2 lb of her einkorn grain that nutritionist, Margaret Pfeiffer, and I ground into bread. Our experience is detailed here. My subsequent blood sugar misadventure, comparing einkorn bread to conventional organic whole wheat bread is detailed here, followed by the odd neurologic effects I experienced here.

Anyone else wishing to try this little ancient wheat experiment with einkorn can also obtain either the unground grain or ground flour through Eli's website, www.growseed.org. Most recently, einkorn pasta is being retailed under the Jovial brand at Whole Foods Market.

If anyone else makes bread or any other food with Eli's einkorn wheat, please let me know:

1) Your blood sugar response (before and 1 hour after consumption)
2) Whether you experienced any evidence of wheat intolerance similar to what you experienced with conventional wheat, e.g., rash, acid reflux, gas and cramping, moodiness, asthma, etc.

But remember: Wheat effects or no, einkorn is still a grain. My belief is that humans do best with little or no grain. The einkorn experience is an effort to identify reasonable compromises so that you and I can have a piece of birthday cake once a year without getting sick.

Genetic incompatibility

Peter has lipoprotein(a), or Lp(a), a genetic pattern shared by 11% of Americans.

It means that Peter inherited a gene that codes for a protein, called apoprotein(a), that attaches to LDL particles, forming the combined particle Lp(a). It also means that his overall pattern responds well to a high-fat, high-protein, low-carbohydrate diet: The small LDL particles that accompany Lp(a) over 90% of the time are reduced, Lp(a) itself is modestly reduced, other abnormalities like high triglycerides (that facilitate Lp(a)'s adverse effects) are corrected. Small LDL particles are, by the way, part of the genetic "package" of Lp(a) in most carriers.

Peter also has another gene for Apo E4, another genetically-determined pattern shared by 19% of Americans. (Another 2% of Americans have two "doses" of Apo E4, i.e., they are homozygotes for E4.) This means that the Apo E protein, normally responsible for liver uptake and disposal of lipoproteins (especially VLDL), is defective. In people with Apo E4, the higher the fat intake, the more LDL particles accumulate. (The explanation for this effect is not entirely clear, but it may represent excessive defective Apo E-enriched VLDL that competes with LDL for liver uptake.) People with Apo E4 therefore drop LDL (and LDL particle number and apoprotein B) with reductions in fat intake.

This is a genetic rock-and-a-hard-place, or what I call a genetic incompatibility. If Peter increases fat and reduces carbohydrates to reduce Lp(a)/small LDL, then LDL measures like LDL particle number, apoprotein B, and LDL cholesterol will increase. Paradoxically, sometimes small LDL particles will even increase in some genetically predisposed people.

If Peter decreases fat and increases carbohydrates, LDL particle number, apoprotein B, and LDL cholesterol will decrease, but the proportion of small LDL will increase and Lp(a) may increase.

Thankfully, such "genetic incompatibilities" are uncommon. In my large practice, for instance, I have about 5 such people.

The message: If you witness paradoxic responses that don't make sense or follow the usual pattern, e.g., reductions in LDL particle number, apoprotein B, and small LDL with reductions in their dietary triggers (i.e., carbohydrates, especially wheat), then consider a competing genetic trait such as Apo E4.

The folly of an RDA for vitamin D

Tom is a 50-year old, 198-lb white male. At the start, his 25-hydroxy vitamin D level was 28.8 ng/ml in July. Tom supplements vitamin D, 2000 units per day, in gelcap form. Six months later in January (winter), Tom's 25-hydroxy vitamin D level: 67.4 ng/ml.

Jerry is another 50-year old white male with similar build and weight. Jerry's starting summer 25-hydroxy vitamin D level: 26.4 ng/ml. Jerry takes 12,000 units vitamin D per day, also in gelcap form. In winter, six months later, Jerry's 25-hydroxy vitamin D level: 63.2 ng/ml.

Two men, similar builds, similar body weight, both Caucasian, similar starting levels of 25-hydroxy vitamin D. Yet they have markedly different needs for vitamin D dose to achieve a similar level of 25-hydroxy vitamin D. Why?

It's unlikely to be due to variation in vitamin D supplement preparations, since I monitor vitamin D levels at least every 6 months and, even with changes in preparations, dose needs remain fairly constant.

The differences in this situation are likely genetically-determined. To my knowledge, however, the precise means by which genetic variation accounts for it has not been worked out.

This highlights the folly of specifying a one-size-fits-all Recommended Daily Allowance (RDA) for vitamin D. The variation in need can be incredible. While needs are partly determined by body size and proportion body fat (the bigger you are, the more you need), I've also seen 105 lb women require 14,000 units and 320-lb men require 1000 units to achieve the same level of 25-hydroxy vitamin D.

An RDA for everyone? Ridiculous. Vitamin D is an individual issue that must be addressed on a person-by-person basis.

Heart scan: Standard of care?

If coronary disease is easy to detect by measuring coronary calcium, shouldn't this represent the standard of care?

In other words, if you've been seeing your doctor and he/she has been monitoring cholesterol levels and, inevitably, talks about statin drugs, then you have a heart attack, unstable angina, or die--yet never knew you had heart disease--isn't this negligence?

Coronary calcium, and thereby coronary atherosclerotic plaque, are markers for the disease itself. Unlike cholesterol, high blood pressure, etc., that represent risk factors for coronary atherosclerotic plaque, coronary calcium is a measure of total plaque: "soft" elements like lipid collections, necrotic tissue, fibrous tissue, as well as "hard" elements like calcium. Because calcium occupies 20% of total atherosclerotic plaque volume, it can be used as an indirect "dipstick" for total plaque.

So why isn't an unexpected heart attack, hospitalization for unstable heart symptions, emergency bypass, etc., not regarded as potential malpractice? These are not benign events, but potentially life-threatening.
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

    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.

    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.

    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.
