More evidence in favor of the Mediterranean diet as the healthiest around

We’ve known for years that the Mediterranean diet helps prolong life and prevent heart attacks, cancer, and strokes in folks who start out healthy.

What about patients with existing cardiovascular disease? I’m talking about history of heart attacks, strokes, angina, and coronary artery disease.

Yep. The Mediterranean diet helps them live longer, too.

Details of the study are at the American Journal of Clinical Nutrition. The research was done at Harvard.

QOTD: Mark Perry on Healthcare Reform

Stretch If You Want, But It Won’t Prevent Sports Injuries

This is a U.S. Army-style sit-up. I do sit-ups with my arms folded across my chest, hands on my shoulders

This is a U.S. Army-style sit-up. I do sit-ups with my arms folded across my chest, hands on my shoulders

I’ve thought that for awhile. Now I’ve got a scientific reference to back it up. Also from the abstract:

Strength training reduced sports injuries to less than 1/3 and overuse injuries could be almost halved.

NYT Reports High Rate of “Mislabelling” in the Herbal Supplement Industry

Around one-third of the popular supplements aren’t what they claim to be.

What's really in that herbal supplement bottle?

What’s really in that herbal supplement bottle?

I doubt the prescription pharmaceutical industry is anywhere near this bad. A quote of a quote:

“This suggests that the problems are widespread and that quality control for many companies, whether through ignorance, incompetence or dishonesty, is unacceptable,” said David Schardt, a senior nutritionist at the Center for Science in the Public Interest, an advocacy group. “Given these results, it’s hard to recommend any herbal supplements to consumers.”

If you know me, you know I don’t quote CSPI very often.

Taking Care of Your Gums May Help Your Heart

…according to an article at University Herald.

The idea is that nasty bacteria around your gums somehow cause arterial inflammation in your heart arteries, which could lead to heart attacks. I’ve written about this before.

A quote from the article:

The researchers followed 420 adults as part of the Oral Infections and Vascular Disease Epidemiology Study (INVEST), a randomly sampled prospective cohort of Northern Manhattan residents. Participants were examined for periodontal infection. Overall, 5,008 plaque samples were taken from several teeth, beneath the gum, and analyzed for 11 bacterial strains linked to periodontal disease and seven control bacteria. Fluid around the gums was sampled to assess levels of Interleukin-1β, a marker of inflammation. Atherosclerosis in both carotid arteries was measured using high-resolution ultrasound.

Over a median follow-up period of three years, the researchers found that improvement in periodontal health-health of the gums-and a reduction in the proportion of specific bacteria linked to periodontal disease correlated to a slower intima-medial thickness (IMT) progression, and worsening periodontal infections paralleled the progression of IMT. Results were adjusted for potential confounders such as body mass index, cholesterol levels, diabetes, and smoking status.

Thickening of the arterial lining is linked to higher rates of heart attack and stroke.

It remains to be seen whether alteration of gum bacteria and periodontal disease via oral self-care and dental care will reduce cardiovascular risk going forward. Stay tuned.
