Hardly a day goes by without headlines touting the health benefits of a Mediterranean-style diet, which has been linked to lower risk of cardiovascular disease and possible brain protection. Now, a recent study suggests this style of eating may also help protect women against breast cancer.

Older adults whove been loading up on calcium - either in their diets or in supplement form - to protect their bones recently got a shock on the nightly news: Extra calcium, according to two new headline-making reviews published in BMJ, was not associated with meaningful benefits for improving bone density or reducing fracture risk.

You already know that fruits and vegetables are good for you - but did you know they might also be good for avoiding extra weight as you age?

A new long-term study from Sweden bolsters the evidence that the type of fats you consume is more important for your health than the total amount of fats in your diet.

Health outcomes were then tracked for an average of 14.5 years.

If you're planning to join the holiday travel crush - or already looking ahead to 2016 vacations - there's good news about your eating options en route. "I actually think that airport choices are beginning to improve a bit, both in terms of take-out and sit-down options," says Jeanne Goldberg, PhD, professor at Tufts' Friedman School and director of the Nutrition Communication Program.

Two of the nations leading nutrition experts have some advice for the federal government: Stop worrying about total fat. Nutrition research has shown that the emphasis on restricting total fat intake is outdated, yet these limits affect everything from Nutrition Facts labels to school lunches to supermarket products. In recent opinion pieces in JAMA and the New York Times, Dariush Mozaffarian, MD, DrPH, and David S. Ludwig, MD, PhD, argue, Its long past time for us to exonerate dietary fat.

Are you getting the minerals in your diet that you need to help reduce stroke risk? In a new look at data on more than 180,000 women in the Nurses Health Study, combined intake of magnesium, potassium and calcium was associated with lower stroke risk. Separately, participants with the highest intake of magnesium and potassium, but not calcium, were also at lower risk.
