Here on SBM we have frequently had cause to criticize the media for poor science reporting and for spreading misinformation. Among many other individual offenders, we have criticized Dr. Oz for promoting alternative medicine on his TV show and gullibly promoting guests who pretend to talk to the dead and pretend to heal people with carnival sideshow tricks. We tend to be negative and critical because somebody has to do it, but it’s not pleasant. For once, I have some good things to say.
The September 12 issue of TIME magazine was a Special Nutrition Issue. The cover featured pictures of food and the title “What to Eat Now: Uncovering the Myths about Food by Dr. Oz.” It devotes 7 pages to an article by him entitled “The Oz Diet: No more myths. No more fads. What you should eat — and why.” This is followed by a 5 page article by John Cloud “Nutrition in a Pill? I took 3000 supplements over five months. Here’s what happened.” Both articles have a rational, science-based perspective without any intrusions of woo-woo.
Oz on What to Eat
Oz acknowledges that the science of nutrition is not simple and that much of what we once believed has been discarded in the face of new knowledge. He debunks a number of popular misconceptions about diet. Most of what he says is consistent with scientific evidence and with mainstream diet advice. Read more »

In 1994 Congress (pushed by Senators Harkin and Hatch) passed DSHEA (the Dietary Supplement Health and Education Act). As regular readers of SBM know, we are not generally happy about this law, which essentially deregulated the supplement industry. Under DSHEA supplements, a category which specifically was defined to include herbals, are regulated more like food than like medicinals.
Since then the flood-gates opened, and there has been open competition in the marketplace for supplement products. This has not resulted, I would argue, in better products – only in slicker and more deceptive claims. What research we have into popular herbals and supplements shows that they are generally worthless (except for targeted vitamin supplementation, which was already part of science-based medicine, and remains so).
A company can essentially put a random combination of plants and vitamins into a pill or liquid and then make whatever health claims they wish for their product, as long as they stay within the “structure-function” guidelines. This means they Read more »

The Mediterranean diet has a new competitor, the spicy diet. Antioxidant spices may reduce the triglyceride response of a high-fat meal by 30% compared to the same meal without them, concluded a study.
The antioxidant potential of spices stems from their phenolic compounds, the authors wrote. Also, some spices increase the blood plasma concentrations of others, and spices are typically eaten as blends, making them good targets to study. Turmeric, cinnamon, rosemary, oregano, black pepper, cloves, garlic powder and paprika were on the short list that researchers examined.
The study compared results in Read more »

There’s a strong association between daily servings of red meat, especially processed meat, and a nearly 20% increased risk of type 2 diabetes, researchers found.
Replacing red meat with healthier proteins, such as low-fat dairy, nuts, or whole grains, can significantly lower the risk, according to a study was published online at the American Journal of Clinical Nutrition.
Researchers reviewed questionnaire responses from 37,083 men followed for 20 years in the Health Professionals Follow-Up Study, from 79,570 women followed for 28 years in the Nurses’ Health Study I, and from 87,504 women followed for 14 years in the Nurses’ Health Study II. Diet was assessed by validated food-frequency questionnaires, and data were updated every four years. Diabetes was confirmed Read more »

Attention, pregnant women! The foods you eat now might influence your babies’ palates after they are born. New research published in the journal Pediatrics, shows that the fetus actually drinks amniotic fluid in the womb. The amniotic fluid is flavored by the foods the mother has recently eaten and flavors can be transmitted to the amniotic fluid and mother’s milk.
It makes sense that as the baby is developing, memories are being created by a sense of taste. Could what a mother eats influence food preferences and odor preferences for life? Researchers fed babies cereal flavored with carrot juice vs. water. They showed that babies who experienced daily carrots in amniotic fluid or mother’s milk ate more carrot-flavored cereal and made less negative faces when eating it.
Julie Mennella studies taste in infants at the Monell Chemical Senses Center (Philadelphia) and she says Read more »
