On Medscape, a recent featured article reviewed a study of the effectiveness of some commonly recommended vaccines. The subjects of the study were children with frequent earaches and runny noses. The study looked at whether those kids were protected after they were vaccinated — 4 times! — for H. flu B (HiB) and pneumococcus. [...]

Shoot the Twinkie!

April 11th, 2009

Recently, there’s been a spate of articles (for instance, this one) claiming that for some, the “obsession” with consuming healthy food has increased our anxiety, pushing some of our kids into eating disorders, and generally taking the fun out of life. While I don’t doubt that a few people use dietary information to make [...]

A Generational Reset Button?

March 18th, 2009

Scientists are learning that a tremendous amount of inheritable information gets encoded into epigenetic “marks.” So far, these marks have shown up as tags on DNA itself, signposts in the protein superstructure, and even information contained in the way that the DNA-protein complex is folded differently into the nuclei of different cells. Environmental and [...]

The Four Food Groups

February 7th, 2009

When I was growing up — and I am probably dating myself here — we were taught that the key to healthy eating was knowing the four food groups — meats, grains, produce, and dairy, if I remember rightly.
We’ve evolved our understanding of nutrition, and the four food groups have long been replaced. Our behavior, [...]

New Hope for School Lunches

January 29th, 2009

The New York Times today carried an article by Tara Parker-Pope called “Obama’s New Chef Skewers School Lunches.” (http://well.blogs.nytimes.com/2009/01/29/new-white-house-chef-skewers-school-lunches/) She quotes extensively from an excellent address Sam Kass (the chef) gave last May. If you’re new to this issue, I recommend the article – actually a blog post — as a good place to [...]

The cost of fresh produce

January 28th, 2009

People tell me, “fruits and vegetables are SO expensive!” Well, yes, they are.
But for processed food, of fast food, of calorie-dense, low-nutrition food, the costs are higher than they appear. The damage to one’s immune system, the accelerated aging caused by oxidative stress, the daily low-level misery and fatigue, high blood pressure, diabetes, [...]

Carotenes and Vitamin A

January 25th, 2009

To feel reasonably sure that they have correctly lined up cause and effect, scientists need to reduce the number of variables in their studies.  In biochemical work, this generally means working each experiment with one nutrient at a time. It has proven to be a fallacy to take the results of these simple studies and [...]

Fructose is a Black Hat

January 25th, 2009

Probably you’ve seen the ad campaign that strives to make high-fructose corn syrup acceptable to the American public as just another sweetener. I’ve been wondering about that for some time. Recently my friend Dr. Deborah McKay, N.D. turned me on to some alarming articles linking increased fructose consumption with a host of [...]
