I just received an RSS alert for the American Journal of Clinical Nutrition's latest articles. This upcoming issue is full of very interesting material:1. Dr. Neil D. Barnard reviews food consumption patterns in the US from 1909 to 2007 (1). This is something I've written about a number of times. The most notable change is that industrial seed oil use has increased by more than 3-fold in the last 40 years, and even more in the last 100 although he doesn't provide those numbers. Butter and lard use declined sharply. Meat...

New Review of Controlled Trials Replacing Saturated fat with Industrial Seed Oils
Posted by Admin in: Cardiovascular disease diet disease fats
Readers Stanley and JBG just informed me of a new review paper by Dr. Dariush Mozaffarian and colleagues. Dr. Mozaffarian is one of the Harvard epidemiologists responsible for the Nurse's Health study. The authors claim that overall, the controlled trials show that replacing saturated fat with polyunsaturated fat from industrial seed oils, but not carbohydrate or monounsaturated fat (as in olive oil), slightly reduces the risk of having a heart attack:These findings provide evidence that consuming PUFA in place of SFA reduces...

Fatty Liver: It's not Just for Grown-ups Anymore
Posted by Admin in: diet disease fats liver
The epidemic of non-alcoholic fatty liver disease (NAFLD) is one of my favorite topics on this blog, due to the liver's role as the body's metabolic "grand central station", as Dr. Philip Wood puts it. The liver plays a critical part in the regulation of sugar, insulin, and lipid levels in the blood. Many of the routine blood tests administered in the doctor's office (blood glucose, cholesterol, etc.) partially reflect liver function.NAFLD is an excessive accumulation of fat in the liver that impairs its function and can...

Vitamin D May Prevent Flu and Asthma
Posted by Admin in: fat-soluble vitamins infection
The AJCN just published a new controlled trial evaluating the effectiveness of vitamin D supplements on flu and asthma (1). Dr. Hiroyuki Ida's group gave Japanese schoolchildren (10 years average age) 1,200 IU of vitamin D3 or placebo per day from December through March. They found that children taking vitamin D had a significantly lower incidence of influenza A but not influenza B. These are two strains of flu that each accounted for roughly half the flu incidence in this population. Sadly, if you add the total flu incidence...

A False Dichotomy
Posted by Admin
In the discussion section of the last post, the eternal argument about non-industrial people arose: were their lives (a) "nasty, brutish and short" (Hobbes), or were they (b) "noble savages" (Shaftesbury) living in Eden? The former argument states that they had awful lives, and we should be glad we're living int he 21st century. The latter argument implies that we should emulate them as much as possible. Each side is bursting with anecdotes to support their position.Any time the discussion reaches this point, it stops providing...

The Paleolithic Mind
Posted by Admin in: Hadza meditation
I went to a meditation retreat this week with the Red Cedar Zen community in Bellingham. It was a good experience. Staring at a wall from 6 am to 9 pm for a few days gives you the opportunity to learn a few things about your mind. Some of these are things you already know on some level, but you just need to have them reinforced. For example, the weight of psychological stress that we carry in modern societies like the US. It's only when it goes away for a while that you can see how heavy it was.I'm totally ignorant of...

Book Review: S.P.E.E.D.
Posted by Admin in: exercise overweight
This book was sent to me by Matt Schoeneberger, who co-authored it with Jeff Thiboutot. Both have master's degrees in exercise science and health promotion. S.P.E.E.D. stands for Sleep, Psychology, Exercise, Environment and Diet. The authors have attempted to create a concise, comprehensive weight loss strategy based on what they feel is the most compelling scientific evidence available. It's subtitled "The Only Weight Loss Book Worth Reading". Despite the subtitle that's impossible to live up to, it was an interesting...
