You've come a long way, baby

In 1945, the room-sized ENIAC vacuum tube computer was first turned on, women began to smoke openly in public, and a US postal stamp cost three cents. And this was the US government's advice on healthy eating:



 

 

 

 

 

 

 

 

 

 

 

 

 

Green and yellow vegetables; oranges, tomatoes, grapefruit; potatoes and other vegetables and fruits; followed by milk and milk products; meat, poultry, fish, or eggs; bread, flour, and cereals, butter and fortified margarine.

In 2011, the computing power of the ENIAC can be performed by a microchip a few millimeters in width, smoking is now banned in public places, and a first class postage stamp has increased in price by 1466%. And this is the new USDA Food Plate for Americans:



 

 

 

 

 

Have we made any progress over the past 65 years? We certainly have in computing power and awareness of the adverse effects of smoking. But have US government agencies like the USDA kept up with nutritional advice? Compare the 2011 Food Plate with the dietary advice of 1945.

It looks to me like the USDA has not only failed to keep up with the evolution of nutritional thought, but has regressed to something close to advising Americans to go out and buy stocks on the eve of the 1929 depression. Most of us discuss issues like the genetic distortions introduced into wheat, corn, and soy; the dangers of fructose; exogenous glycoxidation and lipoxidation products yielded via high-temperature cooking; organic, free-range meats and the dangers of factory farming, etc. None of this, of course, fits the agenda of the USDA.

My advice: The USDA should stay out of the business of offering nutritional advice. They are very bad at it. They also have too many hidden motives to be a reliable source of unbiased information.

 

 

Fasting with green tea

I've been playing around with brief (18-24 hour) fasts with the use of green tea. Of the several variations on fasting, such as juice "fasts,"  I've been most impressed with the green tea experience.

While the weight loss effects of daily green tea consumption are modest, there seems to be a specific satiety effect that has now been demonstrated in multiple studies, such as this and this. In other words, green tea, through an uncertain mechanism, reduces hunger. The effect is not just due to volume, since the effect cannot be reproduced with hot water alone.

I therefore wondered whether green tea might be a useful beverage to consume during a fast, as it might take the "edge" off of hunger. While hunger during a fast in the wheat-free is far less than wheat-consuming humans, there is indeed an occasional twinge of hunger felt.

So I tried it, brewing a fresh 6-8 oz cup evert two hours or so. I brewed a pot in the morning while at home, followed by brewing single cups using my tea infuser at the office. Whenever I began to experience a hunger pang, I brewed another cup and sipped it. I was pleasantly surprised that hunger was considerably reduced. I sailed through my last 18 hours, for instance, effortlessly. The process was actually quite pleasant.

I brew loose Chinese bancha, sencha, and chunmee teas and Japanese gyokuro tea. Gyokuro is my favorite, but also the most expensive. Bancha is more affordable and I've used that most frequently.

If anyone else gives this a try, please report back your experience.

Dreamfields pasta is wheat

An active question on the blogosphere and elsewhere is whether Dreamfields pasta is truly low-carb. Dr. Andreas Eenfeldt of Diet Doctor detailed his high blood glucose experience with it. Jimmy Moore of Livin' La Vida Low Carb had a similar experience, observing virtually no difference when compared to conventional pasta.

The Dreamfields people make the claim that "Dreamfields' patent-pending recipe and manufacturing process protects all but 5 grams of the carbohydrates per serving from being digested and therefore lessens post-meal blood glucose rise as compared to traditional pasta." They call the modified carbohydrates "protected" carbs.



In other words, they are making the claim that they've somehow modified the amylopectin A and amylose molecules in durum wheat flour to inhibit conversion to glucose.

I'd like to add something to the conversation: Dreamfields pasta is wheat. It is a graphic demonstration that, no matter how you cut it, press it, sauce it up, "protect" it, it's all the same thing: wheat. (It reminds me of a bad girlfriend I had in my 20s: She'd put on makeup, a pretty dress, I'd take her out someplace nice . . . She was still an annoying person who whined about everything.)

Wheat is more than a carbohydrate. It is also a collection of over 1000 proteins, including gliadins, glutens, and glutenins. Gliadins, for instance, are degraded to polypeptide exorphins that underlie the addictive potential of wheat, as well as its withdrawal phenomenon on halting consumption. Gliadin-derived exorphins are also the triggers of auditory hallucinations and paranoid delusions in schizophrenia, as well as behavioral outbursts in children with ADHD and autism.

Wheat is a source of lectins that have the curious effect of "unlocking" the proteins of the intestinal lining, the oddly-named "zonulin" proteins, that protect you from ingested foreign molecules. Ingest wheat lectins and all manner of foreign molecules gain entry into your bloodstream. Cholera works by a similar mechanism. (How about a love story: Bread in the time of cholera?)

Glutens, of course, are responsible for triggering celiac disease, the devastating small intestinal disease that now afflicts 3 million Americans, although 2.7 million don't even know it. Glutens are also responsible for neurologic conditions like cerebellar ataxia, peripheral neuropathy, and dementia ("gluten encephalopathy") and the skin condition, dermatitis herpetiformis.

Then there are the conditions for which the active wheat components have not been identified, including acid reflux, irritable bowel syndrome, asthma (excepting "bakers' asthma), rheumatoid arthritis, edema and fluid retention, and a long list of skin conditions from alopecia to gangrene.

My point: Yeah, Dreamfields pastas, from these instructive experiences, acts a lot like conventional durum wheat pasta. But, even if Dreamfields or somebody else perfects the low-carb aspect of it, it's still wheat. Modern wheat is the genetically tarted-up version of Triticum aestivum, the product of genetic shenanigans from the 1960s and 1970s.

Bet you can't fast

People who continue to consume the world's most destructive grain, i.e., wheat, can rarely endure fasting--not eating for an extended period--except by mustering up monumental willpower. That's because wheat is a powerful appetite stimulant through its 2-hour cycle of exaggerated glycemia followed by a glucose low, along with its addictive exorphin effect. Wheat elimination is therefore an important first step towards allowing you to consider fasting.

Why fast? I regard fasting as among the most underappreciated and underutilized strategies for health.

In its purest form, fasting means eating nothing while maintaining hydration with water alone. (Inadequate hydration is the most common reason for failing, often experienced as nausea or lightheadedness.) You can fast for as briefly as 15 hours or as long as several weeks (though I tell people that any more than 5 days and supervision is required, as electrolyte distortions like dangerously low magnesium levels can develop).

Among its many physiological benefits, fasting can:

  • Reduce blood pressure. The blood pressure reducing effect can be so substantial that I usually have people hold some blood pressure medications, especially ACE inhibitors and ARB agents, during the fast since blood pressure will drop to normal even without the drugs. (A fascinating phenomenon all by itself.)

  • Reduce visceral fat, i.e., the fat that releases inflammatory mediators and generates resistance to insulin.

  • Reduce inflammatory measures

  • Reduce liver output of VLDL that cascades into reduced small LDL, improved HDL "architecture," and improved insulin responsiveness. (The opposite of fasting is "grazing," the ridiculous strategy advocated by many dietitians to control weight. Grazing, or eating small meals every two hours, is incredibly destructive for the opposite reason: flagrant provocation of VLDL production.)

  • Accelerate weight loss. One pound per day is typical.


Beyond this, fasting also achieves unique subjective benefits, including reduced appetite upon resumption of eating. You will find that as single boiled egg or a few slices of cucumber, for example, rapidly generate a feeling of fullness and satisfaction. Most people also experience greater appreciation of food--the sensory experience of eating is heightened and your sense of texture, flavors, sweetness, sourness, etc. are magnified.

After decades of the sense-deadening effects of processed foods--over-sugared, over-salted, reheated, dehydrated then just-add-water foods--fasting reawakens your appreciation for simple, real food. On breaking one of my fasts, I had a slice of green pepper. Despite its simplicity, it was a veritable feast of flavors and textures. Just a few more bites and I was full and satisfied.

Once you've fasted, I believe that you will see why it is often practiced as part of religious ritual. It has an almost spiritual effect.

Total cholesterol 220

Talking about total cholesterol is like wearing a tie-dyed t-shirt with the peace sign emblazoned on the front: So totally 60s and out of date.

But talk of total cholesterol somehow keeps on coming back. After I spend 45 minutes discussing a patient's lipoprotein patterns, for instance, they'll asking something like, "But what's my total cholesterol?"

To help put this ridiculous notion of total cholesterol to rest, let me paint several pictures of what total cholesterol can tell you. Let's start with a theoretical, but very common, total cholesterol value of 220 mg/dl. Recall that:

LDL cholesterol = total cholesterol - HDL cholesterol - triglycerides/5

Note that LDL cholesterol is nearly always a calculated value. (Yes, your doctor has been treating a calculated, what I call "fictitious," value.)

Rearranging the equation:

Total cholesterol = LDL cholesterol + HDL cholesterol + Triglycerides/5

This relationship means that a great many variations are possible, all under total cholesterol = 220 mg/dl. For example:

LDL 95 mg/dl + HDL 105 mg/dl + Triglycerides 100 mg/dl

(a relatively low-risk pattern for heart disease)

LDL 160 mg/dl + HDL 50 mg/dl + Triglycerides 50 mg/dl

(an indeterminate risk pattern, potentially moderate risk)

LDL 120 mg/dl + HDL 30 mg/dl + Triglycerides 350 mg/dl

(a potentially high-risk pattern)

LDL 60 mg/dl + HDL 25 mg/dl + Triglycerides 675 mg/dl

(an indeterminate risk pattern)

 

That's just a sample of the incredible variation of patterns that can all fall under this simple observation, total cholesterol 220 mg/dl.

Total cholesterol is an outdated concept, one ready long ago for the junk heap of outdated ideas. It's time to throw total cholesterol out in the trash along with beliefs like high-fat intake causes diabetes, whole grains are healthy, and the tooth fairy will leave you money when you leave your molars under the pillow.

Scientists are freakin' liars

So says Tom Naughton, referring to the frequent misinterpretations or misrepresentations of data that characterize much medical research. Dr. Andreas Eenfeldt posted Tom Naughton's recent wonderfully engaging and hilarious talk from Jimmy Moore's Low-Carb Cruise on his Diet Doctor blog.

Comedian and blogger Tom Naughton, also the filmmaker of the movie Fat Head, has brought humor and personality into the low-carb movement. I told my wife to watch it and I could hear her laughing from 30 feet away while watching her laptop.

Dr. Eenfeldt is a sensation of sorts himself, making a big low-carb splash in Sweden. While I missed the cruise this year (due to time pressures), it's clear that Eenfeldt and Naughton have contributed substantially to helping people understand the nonsense that passes as dietary advice in the U.S. and the world.

I watched Naughton's talk while eating my three eggs scrambled with ricotta cheese. I almost spit my eggs out at the computer screen I was laughing so hard.

 

Tell me your wheat elimination story and receive a copy of my new book, Wheat Belly

I'm looking for interesting wheat-free experiences.

For the past year, I have been writing my new book, Wheat Belly . After many, many late nights and soccer games missed, it's now finished. The book will be out in fall, 2011, to be published by Rodale, the Prevention Magazine people.

Wheat Belly will provide, in excruciating detail, the discussion of how wheat was transformed from innocent wild grass to incredible genetically-altered Frankengrain and why it has become such a health nuisance.

I am looking for interesting stories of wheat elimination for the online and special editions of the book. If you have an interesting tale of wheat-elimination successes, woes, or drama, I'd like to hear about it. Even better, if you would agree to be interviewed by phone (not for live use, just for comments and detail), the editors at Rodale will help tell your story.

If we use your story, I will have a free copy of the new Wheat Belly sent to you when it becomes available.

Please post your story in the comments here. I will then need to obtain your contact info, which we will do privately.

 

Real men don't eat carbs

Real men don't eat carbs. At least they don't eat them without eventually paying the price.

How do carbohydrates, especially those contained in "healthy whole grains," impair maleness? Several ways:

--Consume carbohydrates, especially the exceptional glucose-increasing amylopectin A from wheat, and visceral fat grows. Visceral fat increases estrogen levels; estrogen, in effect, opposes the masculinizing effects of testosterone. Overweight males typically have low testosterone and high estrogen, a cause for depression, emotionality, weight gain, and low libido.

--Sugar-provoking carbohydrates like wheat cause visceral fat to accumulate which, in turn, triggers prolactin to be released. Increased prolactin in a male causes growth of breasts: "man boobs,""man cans," "moobs," etc. This is why male breast reduction surgery is booming at double-digit growth rates. In cities like LA, you can see billboards advertising male breast reduction surgery.

--Carbohydrates increase visceral fat that sets the stage for postprandial abnormalities, i.e., markedly increased and persistent lipoproteins, like chylomicron remnants and VLDL particles, that impair endothelial function literally within minutes to hours of ingestion. Impaired endothelial function underlies erectile dysfunction. This is why Internet spammers so enthusiastically send you offers for discounted Viagra.

--Carbohydrates increase blood sugar which provokes the process of glycation, glucose modification of proteins, that also contributes to endothelial dysfunction followed by erectile dysfunction.

Real men therefore avoid carbs.

Insulin secretagogue

Insulin secretagogue

Dairy products have the peculiar property of triggering pancreatic release of insulin. The research group at Lund University in Sweden have contributed the most to documenting this phenomenon:




Mean (±SEM) incremental changes (?) in serum insulin in response to equal amounts of carbohydrate from a white-wheat-bread reference meal (x) and test meals of whey (?), milk (?), cheese (?), cod (?), gluten-low (?), and gluten-high (?) meals. From Nilsson 2004.

Note that it is the area under the curve (AUC), not the peak value, that assumes greatest importance.

Dairy products, especially milk, whey, and yogurt, are insulin secretagogues: they stimulate pancreatic release of insulin. The effect is likely due to amino acids and/or polypeptides in dairy products. (The effect is less prominent with cheese. Also see this study.)

By conventional wisdom, this may be a good thing, since the excess insulin will blunt the glucose rise after consumption. However, in my book, this is not such a good thing, since most of us have tired, beaten, overworked pancreatic beta cells from our decades of carbohydrate overconsumption. I fear that the effect of dairy products just take us a bit closer to beta cell failure: diabetes.

Good news: The effect is least with cheese.

    Dr Davis, interesting study. But both links go to the same study, Nilsson 2004, shouldn't the second link go to second study?

    Hi, Prague-

    Absolutely right. Thanks for catching that.

    Actually, both observations were best made in the same study. While the effect of milk on insulin secretion is firm, the question of cheese has not been as well explored. There's also the possibility that, because cheese is like wine in that there are thousands of variations (organism chosen for fermentation, fat content, etc.), there might even be variation from cheese to cheese.

    How can you have a test meal of cod which contains the same carbohydrate count as a reference bread meal when cod has no carbohydrates?

  • praguestepchild

    3/14/2011 5:32:53 PM |

    But I'm not sure why they used reconstituted milk. Why not normal (3.5%) milk, or perhaps normal and skim? They do say, "Interestingly, there is epidemiologic evidence suggesting that overweight subjects with a high intake of milk and dairy products are at a lower risk of developing diseases related to the insulin resistance syndrome" Perhaps because the SFA content?

    I know that a tall glass of milk can surprisingly jack up blood sugar, and they say that "The insulin response to milk products does not relate solely on the lactose component." Interesting. Still, much better a glass of milk than a glass of apple juice.

    Hi, Stephen--

    Yes, crucial distinction. To my knowledge, that has not been done, though I would fully expect that there is no effect.

    Hi, Brent--

    The cod must have been breaded. The cod they used was purchased in a grocery store.

  • Might-o'chondri-AL

    3/15/2011 12:00:55 AM |

    It would be interesting to see how different sources of milk influence insulin secretion. Aside from the distinct breeds of cattle many pastoralists use goat & sheep; plowmen milk  buffalo and some artic milking of reindeer (it takes 2 people, one to hold the horns).

    My dairy consumption is in the form of Kefir "Quark". This is cultured milk that is then drained of it's whey. In the Mediterranean & Mid-east regions they use yogurt "quark"; but named differently by each culture in their own vernacular. In India it would be "curd", and usually from water buffalo milk.

    "Quark" is a fermentation process byproduct and the minerals in milk are lost (soluble) in the whey. In other words, there is minimal calcium in "quark".(A few Posts back readers may recall Doc restricting calcium for reducing aortic calcification. Elsewhere, some men may recall having seen prostate studies suggesting excess calcium is not ideal.)

    Don't forget "Butter and Insulin".

    It was one of Dr. Davis' more controversial blog posts, especially among us butter lovers...

    I'm also not quite so eager to throw out my whey protein and BCAA supplements either. Not when they provide the most bio-available protein that has long been proven to be beneficial for human muscle synthesis.  Why eliminate a dietary source that can help tip the balance toward a favorable muscle to fat composition ratio?... that in turn actually improves fat metabolism and insulin sensitivity?

  • Might-o'chondri-AL

    3/15/2011 8:55:39 AM |

    Study used 28 gr. spray dried whey (among other items) that was reconstituted in 550 gr. water. It showed that whey had fastest uptake of insulin-otrophic (secretagogue) amino acids (namely leucine, valine, isoleucine, lysine and theonine).

    Compared over 1.5 hours to same gr. weight of white bread (studies reference food) whey's insulin reaction was 90% greater. It's blood glucose however rose notably less than the reference food's blood sugar did.

    I'd like to understand better the way insulin "spikes" have beneficial functions in non-diabetics. It seems to me that there may be times of day (circadian) when elevated insulin serves a signalling purpose; late night in front of the TV seems unlikely. Anybody?

  • Terry

    3/15/2011 4:10:25 PM |

    Someone please correct me if I am mistaken - but I think that what this boils down to is the amount of lactose in a particular dairy product and would that not explain the difference between, for example, the effects of milk v.s cheese?

  • Might-o'chondri-AL

    3/15/2011 7:02:59 PM |

    Hi Terry,
    Cheese doesn't have the whey any more; it gets drained off. The whey proteins are the insulin spiker (Doc's post is on how insulin reacts). Milk's lactose (milk sugar) apparently has more to do with the way blood glucose (sugar)reacts to milk, irregardless of the milk still containing it's whey.

  • Karn

    3/16/2011 1:14:36 AM |

    Did anyone actually read the study.  The cod was not breaded, they added lactose to each product to bring the carb count up to 25g, including the cod.

    Also, yogurt is not mentioned at all in this study, so not sure why you are lumping it in here.

    It would be difficult to design a diet using the II of these two papers, because their insulin index (II) is based on equal carb portions. Some foods do not have much carbs, so they add carb (lactose) to them.  A better table for a variety of foods is given in this  paper * where II is calculated based on equal calorie portions, so we know the weight of each portion (from Table 2).  In this paper the values for GI (glucose index) and II are (from Table 4)

    So the whey protein isolate (100%) protein that I add to my morning smoothie is causing an insulin spike?

    Bodybuilders favor whey protein for its insulin spiking properties. Their idea that the insuin drives creatine and amino acids to muscle tissue Ne c'est pas?

    Could they be engaging in diabetogenic behavior?

    Hi Terry,
    Greek yogurt is reduced whey (they drain some off); that's how they make it thicker.
    Yogurt's carb level is less than milk because the fermentation bacteria mainly fed on the milk sugar(lactose).

    We are left to conclude that with dairy you look bad on paper but turn out to look pretty darn good in real life.  Especially considering that overweight would be associated with higher risk of insulin resistance syndrome indicating, potentially, that dairy actually has a powerful protective effect.

    Is it not possible whey's sustained insulin response indicates it is part of a feed back loop? For active people (ex: body builders, herdsmen) the dynamic is more valuable than for the sedentary; modern sedentary lifestyle & insulin spike are a different dynamic.  

    Many crucial cells must get their glucose diffused to the extra-cellular spaces; blood doesn't get to touch every cell.
    Insulin "spike" and steady reign may be evolutionary to give crucial cells chance to sip some glucose. The spike is a signal
    there's plenty for every cell; it prevents first come first served cells from going into overdrive and pulling in all the blood glucose.

    "By conventional wisdom, this may be a good thing, but not in my book."

    Well dear doctor we are all entitled to opinions, but in this particular case your book needs revision:

    A population-based prospective study (CARDIA) revealed that dairy consumption was inversely associated with the incidence of all components of the insulin resistance syndrome (IRS) among overweight individuals (BMI>=25kg/m2).

    *** Each daily occasion of dairy consumption was associated with 21% lower odds of IRS. ***

    These associations were similar for blacks and whites and for men and women.


    If you believe this to wrong, please direct us to what bases your conclusion.

    Hi Annon.,
    ? Insulin resistance decreased by dairy in what form; ie:
    hard cheese (essentially no whey), klabbered (yogurt/kefir) with bacteria, fluid w/or w/o "x" % milk fat ...? My reply to you on "Smoothies" thread got lost, so am pleased you posted again here.

    BMI is a ratio of proportionality to the persons height. A tall and thin individual can score a higher BMI than a short and fat one. BMI doesn't tell ratio of lean:fat in our body mass.

    One day I'd like to see all studies use their subject's "Ponderal" proportion. This is the individual weight (in kilograms) divided by their height cubed (in meters).

    It is superior for assesing what's happening with obesity. The "ponderal" change will reflect basal inflammation and can be cross-referenced to previous C Reactive Protein measurements to track if any complication are occuring.

    Is there a home insulin meter, like the home glucose meter? It would help a lot.

    We tend to over think things latching on to this isolated nutrient or that. Your overall diet is what counts. People have been drinking milk/yoghurt/kefir and eating cheese for thousands of years. Dairy is a pretty damned good food (especially cheese).

    It seems to me that Weston Price (the man and organization) has it just about right.
