Is Sugar Toxic?

This NYT Magazine article by Gary Taubes is an excellent read.  It begins by examining Robert Lustig’s accusations that sugar is a toxic poison, but goes on to ask some very important questions about the relationship between sugar, high fructose corn syrup, and obesity, diabetes and cancer. Much needed research may not be forthcoming, however.

As Lustig points out, sugar and high-fructose corn syrup are certainly not “acute toxins” of the kind the F.D.A. typically regulates and the effects of which can be studied over the course of days or months. The question is whether they’re “chronic toxins,” which means “not toxic after one meal, but after 1,000 meals.” This means that what Tappy calls “intervention studies” have to go on for significantly longer than 1,000 meals to be meaningful.

At the moment, the National Institutes of Health are supporting surprisingly few clinical trials related to sugar and high-fructose corn syrup in the U.S. All are small, and none will last more than a few months.

Butter, red meat not so bad for you after all?

Based on dietary recommendations that were introduced in the US (1977) and in the UK (1983) to (1) reduce overall fat consumption to 30% of total energy intake and (2) reduce saturated fat consumption to 10% of total energy intake, we all jumped on the bandwagon and nixed butter, meat, dairy and cheese, replacing them in our diet with an overabundance of carbohydrates, a practice Nina Teicholz, author of The Big Fat Surprise, says contributed to our current problems with obesity and related health problems.

To support this view, a new report published in the online journal BMJ Open Heart calls that long-standing advice into question. Researchers reviewed and analyzed the clinical trials that were originally used back in the 1970s and 80s as the basis for warnings about dietary fat, and they found that the evidence just didn’t add up.

The Diet-Heart Myth: Cholesterol and Saturated Fat Are Not the Enemy

Four part article by Chris Kresser (Let’s Take Back Your Health) examining the truths and lies about cholesterol, saturated fat and cardiovascular disease.

Cardiovascular disease is one of the most misdiagnosed and mistreated conditions in medicine. We’ve learned a tremendous amount about what causes heart disease over the past decade, but the medical establishment is still operating on outdated science from 40-50 years ago.

In this 4-part series, I’m going to debunk 3 common myths about heart disease:

  1. Eating cholesterol and saturated fat raises cholesterol levels in the blood.
  2. High cholesterol in the blood is the cause of heart disease.
  3. Statins save lives in healthy people without heart disease.
