A small pilot study at Tufts Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) raises the intriguing possibility that following a new behavioral weight-loss program for six months can in turn reprogram your brains food cravings.

The scans showed that it is possible to train the brain to reverse cravings and temptation for unhealthy food, replacing former cravings with temptation for healthy food.

If a little is good, most Americans are accustomed to thinking, more must be better and a lot must be better still. When it comes to vitamins and minerals, however, it is possible to get too much of a good thing-especially if some of your nutrients are coming from pills instead of food.Remember that most of your vitamin and mineral needs can be safely met by a thoughtful diet, cautions Irwin H. Rosenberg, MD, editor of the Tufts Health & Nutrition Letter. The use of so-called dietary supplements will always be associated with some degree of risk.

A new clinical trial and a review of the evidence both suggest eating tree nuts may help fight diabetes. Tree nuts include walnuts, hazelnuts, almonds, Brazil nuts, cashews, pecans, pine nuts, macadamias and pistachios. One study reported that pistachios improved markers of blood sugar and inflammation in people at risk for diabetes, while the second concluded that tree nuts of various types contribute to better glycemic control in patients already diagnosed with type 2 diabetes.

Products containing coconut, coconut oil and coconut milk are popping up everywhere, with marketers touting coconut as the latest superfood. But a recent warning letter from the US Food and Drug Administration cautions coconut boosters not to overreach. The FDA warned that coconut products cant be labeled as healthy if they contain more than 1 gram of saturated fat or more than 15% of calories come from saturated fat. Some have claimed that the saturated fat in coconut is different because its mostly lauric acid, which a few small studies suggest is metabolized differently than other saturated fats. But the FDA isnt buying that argument, noting that coconut products might contain as much as 16 grams of saturated fat per serving.

A new analysis of data from the Womens Health Initiative (WHI) shows that postmenopausal women who consume the most potassium in their diets are at lower risk of suffering a stroke. The association was strongest in women without hypertension. Although the WHI is an observational study, which cant prove cause and effect, scientists say it provides another reason to boost your potassium intake-especially given that most Americans fall far short of meeting recommended potassium requirements.

A recent headline-grabbing study seemed to settle the issue of low-carb versus low-fat diets definitively, reporting that a low-carb diet was not only more effective for weight loss, but also better for cardiovascular risk factors. In the yearlong study of 148 obese volunteers, those assigned to a low-carbohydrate regimen lost nearly eight pounds more and showed greater improvements in triglycerides, HDL cholesterol and a standard risk score for heart disease than a low-fat group. Both groups saw similar decreases in unhealthy LDL cholesterol. Researchers said the cardiovascular findings were notable because of concerns that low-carb diets might boost unhealthy cholesterol levels as dieters substitute fats for carbohydrates.

The ancient Egyptians were onto something when they paid their pyramid-building crews with onions, and placed onions in the tombs of their pharaohs. In the Biblical account of the Exodus, onions are among the Egyptian foods the children of Israel miss. In ancient Greece, Olympians prepared for the games by drinking onion juice and rubbing their bodies with onions.
