A Gluten-free January

Are You Gluten Sensitive?Many people are totally unaware of the fact that they react poorly to gluten. Because they've been eating wheat, barley and/or rye products every day for virtually their entire lives, they don't know what their bodies feel like without gluten. In susceptible people, eating gluten is linked to a dizzying array of health problems that stem from an immune reaction to gliadins and other proteins in gluten (1). Are you a susceptible person? How do you know?The gold standard way to detect a gluten sensitivity...

Dairy Fat and Diabetes

IntroductionHaving access to embargoed news from the Annals of Internal Medicine is really fun. I get to report on important studies at the same time as the news media. But this week, I got my hands on a study that I'm not sure will be widely reported (Mozaffarian et al. Trans-palmitoleic Acid, Metabolic Risk Factors, and New-Onset Diabetes in US Adults. Ann Internal Med. 2010). Why? Because it suggests that dairy fat may protect against diabetes.The lead author is Dr. Dariush Mozaffarian, whose meta-analysis of diet-heart...

Potato Diet Interpretation

If you read my post on December 16th, you know that Chris Voigt saw remarkable fat loss and improvements in health markers as a result of two months of eating almost nothing but potatoes. This has left many people scratching their heads, because potatoes are not generally viewed as a healthy food. This is partially due to the fact that potatoes are very rich in carbohydrate, which also happens to be a quickly digested type, resulting in a high glycemic index. The glycemic index refers to the degree to which a particular...

Trouble With RSS Feed?

I've received several comments that my blog posts are no longer showing up in peoples' RSS feeds. I've gone into my settings, and the blog is still set to full feed mode, so I don't know why that would be. I'm trying to understand if the problem is widespread or only affects a few people. Please let me know in the comments section if new posts (since the potatoes and human health series) are not showing up in your reader. Also, please let me know if new posts are showing up. Thank...

Interview with Chris Voigt of 20 Potatoes a Day

IntroductionChris Voigt is the executive director of the Washington State Potato Commission, which supports and promotes the Washington state potato industry (1). On October 1st, Mr. Voigt began a two month, potato-only diet to raise awareness about the health properties of potatoes. It was partially in response to the recent decision by the federal WIC (Women, Infants and Children) low-income assistance program to remove potatoes from...

Dr. Mellanby's Tooth Decay Reversal Diet

I have a lot of admiration for Drs. Edward and May Mellanby. A husband-and-wife team, they discovered vitamin D, and determined that rickets is caused by poor calcium (or phosphorus) status, typically due to vitamin D deficiency. They believed that an ideal diet is omnivorous, based on whole foods, and offers an adequate supply of fat-soluble vitamins and easily absorbed minerals. They also felt that grain intake should be modest, as...

Interview with a Kitavan

Kitava is a Melanesian island that has maintained an almost entirely traditional, non-industrial diet until very recently. It was the subject of a study by Dr. Staffan Lindeberg and colleagues, which I have written about many times, in which they demonstrated that Kitavans have a very low (undetectable) rate of heart attack, stroke, diabetes and overweight. Dr. Lindeberg described their diet as consisting mostly of yam, sweet potato, taro, cassava, coconut, fruit, fish and vegetables. Over the seven days that Dr. Lindeberg...

Diet-Heart Controlled Trials: a New Literature Review

Many controlled studies have measured the cardiovascular effects of replacing animal ("saturated") fats with seed oils (predominantly the omega-6 polyunsaturated fat linoleic acid) in humans. A number of these studies recorded heart attacks and total mortality during the following 1-8 years. Several investigators have done meta-analyses (literature reviews) to try to tease out overall conclusions from these studies.I'm pleased to point out a new meta-analysis of these controlled trials by Dr. Christopher Ramsden and colleagues...

Choline and Fatty Liver

I've been writing about non-alcoholic fatty liver disorder (NAFLD) since the early days of this blog, because it's an alarmingly common disorder (roughly a quarter of Americans affected) that is typically undiagnosed. It often progresses into its more serious cousin non-alcoholic steatohepatitis (NASH), an inflammatory condition that causes liver damage and can progress to cancer. In a number of previous posts, I pinpointed excess sugar and seed oil consumption as culprits in NAFLD and NASH (1, 2, 3, 4, 5).Chris Masterjohn...

Glucose Tolerance in Non-industrial Cultures

BackgroundGlucose is the predominant blood sugar and one of the body's two main fuel sources (the other is fatty acids). Glucose, in one form or another, is also the main form of digestible dietary carbohydrate in nearly all human diets. Starch is made of long chains of glucose molecules, which are rapidly liberated and absorbed during digestion. Sucrose, or table sugar, is made of one glucose and one fructose molecule, which are separated...
