What About a Low-Carb Vegetarian Diet for Diabetes?

It works for David Mendosa, who’s been doing it for three years. He shares some ideas on how to do it at the link below. From the intro:

About nine years ago, I started to eat only food low in carbohydrates that don’t have a high glycemic index.  I knew that this was the only proven way to bring my blood glucose level down where I wanted it to be without using drugs or supplements. My most recent A1C test showed that my level is 5.1 percent, well within the range considered normal.

While continuing to eat this way, about three years ago I added the further restriction of eating no meat, fish, or seafood. This was a substantial shift in what I was eating, and I made it mainly because I don’t want to be intentionally responsible for the death of animals or other sentient beings. Only later did I begin to realize its health benefits.

David seems to adhere to the lacto-ovo strain of vegetarianism, rather than vegan or pesco-vegetarian. In other words, he’ll eat eggs and milk products but not fish. I suspect he eats under 40 grams/day of digestible carbohydrate.

Here are more of David’s ideas on implementation of a very low-carb vegetarian diet.

Can You Manage Your Type 2 Diabetes Without Drugs?

David Mendosa says you can. I’m not quite that optimistic, but probably a majority can, if they have the knowledge, discipline, and willpower. Here are some snippets from David’s blog:

You can use drugs to bring your A1C level down to normal. That’s a good thing. But this strategy does have its costs, and those costs aren’t just money out of your pocket or your checkbook. The worst of those costs are the potential side effects of the drugs.

***

But some of us think we have a safer strategy of managing our diabetes without drugs. Back in 2007 I joined this group with the encouragement of a good friend of mine who is a Certified Diabetes Educator. Before that, I had 14 years of experience taking a wide range of diabetes drugs, including two different sulfonylureas (Diaßeta and Amyrl), Glucophage (metformin), and Byetta. For the past six years I haven’t taking any diabetes drugs, and yet I keep my diabetes in control with an A1C level usually about 5.4.

I had to make three big changes in my life when I went off the diabetes drugs, and they are hard at first. But now they are a routine part of my life, and I would never go back to my old ways. The changes that I had to make are those that almost everyone who has diabetes has to make. In order of importance, I had (1) to lose weight, (2) eat fewer carbohydrates, and (3) exercise more.

Read the whole enchilada. It’s brief.

Is Your Blood Sugar Meter Accurate?

David Mendosa reviewed some reviews on home blood glucose monitor accuracy and reproducibility.  He was motivated by a recent review in Consumer Reports.  You’ll want to click through his links for details.  The last time I looked into this, I learned that a device could receive FDA approval if it could measure accuracy to within 20% of the actual blood sugar value as determined by a laboratory machine.  For a blood sugar of 200 mg/dl (11.1 mmol/l), the home device could give you a value anywhere between 160 and 240 mg/dl (8.9 to 13.3 mmol/l).  That doesn’t exactly inspire confidence, does it?

Dental Problems and Systemic Chronic Disease: A Carbohydrate Connection?

Perfect health on a carnivorous, low-carb diet

Perfect health on a carnivorous, low-carb diet

Dentists are considering a return to an old theory that dietary carbohydrates first cause dental diseases, then certain systemic chronic diseases, according to a review in the June 1, 2009, Journal of Dental Research. 

We’ve known for years that some dental and systemic diseases are associated with each other, both for individuals and populations.  For example, gingivitis and periodontal disease are associated with type 2 diabetes and coronary heart disease.  The exact nature of that association is not clear.  In the 1990s it seemed that infections – chlamydia, for example – might be the unifying link, but this has not been supported by subsequent research.     

The article is written by Dr. Philippe P. Hujoel, who has been active in dental research for decades and is affiliated with the University of Washington (Seattle).  He is no bomb-throwing, crazed, radical. 

The “old theory” to which I referred is the Cleave-Yudkin idea from the 1960s and ’70s that excessive intake of fermentable carbohydrates, in the absence of good dental care, leads both to certain dental diseases – caries (cavities), periodontal disease, certain oral cancers, and leukoplakia – and to some common systemic chronic non-communicable diseases such as coronary heart disease, type 2 diabetes, some cancers, and dementia.  In other words, dietary carbohydrates cause both dental and systemic diseases – not all cases of those diseases, of course, but some.   

Dr. Hujoel does not define “fermentable” carbohydrates in the article.  My American Heritage Dictionary defines fermentation as:

  1. the anaerobic conversion of sugar to carbon dioxide and alcohol by yeast
  2. any of a group of chemical reactions induced by living or nonliving ferments that split complex organic compunds into relatively simple substances

As reported in David Mendosa’s blog at MyDiabetesCentral.com, Dr. Hujoel said, “Non-fermentable carbohydrates are fibers.”  Dr. Hujoel also shared some personal tidbits there. 

In the context of excessive carbohydrate intake, the article frequently mentions sugar, refined carbs, and high-glycemic-index carbs.  Dental effects of excessive carb intake can appear within weeks or months, whereas the sysemtic effects may take decades. 

Hujoel compares and contrasts Ancel Keys’ Diet-Heart/Lipid Hypothesis with the Cleave-Yudkin Carbohydrate Theory.  In Dr. Hujoel’s view, the latest research data favor the Carbohydrate Theory as an explanation of many cases of the aforementioned dental and systemic chronic diseases.  If correct, the theory has important implications for prevention of dental and systemic diseases: namely, dietary carbohydrate restriction.

Adherents of the paleo diet and low-carb diets will love this article; it supports their choices.

I agree with Dr. Hujoel that we need a long-term prospective trial of serious low-carb eating versus the standard American high-carb diet.  Take 20,000 people, randomize them to one of the two diets, follow their dental and systemic health over 15-30 years, then compare the two groups.  Problem is, I’m not sure it can be done.  It’s hard enough for most people to follow a low-carb diet for four months.  And I’m asking for 30 years?!   

Dr. Hujoel writes:

Possibly, when it comes to fermentable carbohydrates, teeth would then become to the medical and dental professionals what they have always been for paleoanthropologists: “extremely informative about age, sex, diet, health.”

Dr. Hujoel mentioned a review of six studies that showed a 30% reduction in gingivitis score by following a diet moderately reduced in carbs.  He mentions the aphorism: “no carbohydrates, no caries.”  Anyone prone to dental caries or ongoing periodontal disease should do further research to see if switching to low-carb eating might improve the situation. 

Don’t be surprised if your dentist isn’t very familiar with the concept.  Has he ever mentioned it to you?
