Is milk from grass-fed cows more heart-healthy?

Heart Health, Nutritional Health
Reuters Health has a report I thought you might find interesting. It's based upon a new study answering the question, "If milk does the heart good, does it do the heart better if it comes from dairy cows grazed on grass instead of on feedlots?" The bottom line? Cow's milk from cows grazed on grass may actually be heart healthy. Earlier experiments have shown that cows on a diet of fresh grass produce milk with five times as much of an unsaturated fat called conjugated linoleic acid (CLA) than do cows fed processed grains. Studies in animals have suggested that CLAs can protect the heart, and help in weight loss.

Alternative Medicine, Cancer
The Los Angeles Times "Booster Shots" blog reports that shark cartilage may not benefit patients with lung cancer, according to a study published in the Journal of the National Cancer Institute.

Today I'm in Orlando, Florida, where I'll be speaking to the Florida Academy of Family Physicians on this exact issue. And, I find that most of my patients and most physicians are simply unaware of the danger. The New York Times is reporting, "Nearly all of the herbal dietary supplements tested in a Congressional investigation contained trace amounts of lead and other contaminants, and some supplement sellers made illegal claims that their products can cure cancer and other diseases, investigators found." Although the "levels of heavy metals – including mercury, cadmium and arsenic – did not exceed thresholds considered dangerous," almost half of them "contained pesticide residues that appeared to exceed legal limits." Notably, "Dr. Joshua M. Sharfstein, principal deputy commissioner of the Food and Drug Administration, said in an interview…
