Sometimes, it doesn't take a major diet overhaul to get significant health benefits. Small changes can be helpful, too.
This seems to be the take-home message from a new study in JAMA Internal Medicine linking olive oil and nuts to improved survival from prostate cancer.
Researchers studied the fat intake of more than 4,500 men who had been diagnosed with non-metastatic prostate cancer (this is cancer that's still confined to the prostate gland and has not spread to another place in the body).

If you're looking for the definitive study that might persuade meat lovers to become vegetarians, this may not be it.
New research published in JAMA Internal Medicine finds that vegetarian diets are linked to a slightly lower risk of early death — about 12 percent lower over a period of about six years of follow-up. But the link to longevity was more significant in men compared with women.
A typical Swedish meal of fried herring and lingonberries includes some of the local ingredients of the healthy Nordic diet prescribed in a new study.
The Mediterranean diet has long been a darling of nutrition experts as a proven way to prevent some chronic diseases. Heavy on olive oil, vegetables, fruit, nuts and fish, the diet most recently has been shown to reduce the risk of heart attacks, strokes and dying compared with a typical low-fat diet.

For decades, scientists have believed our ancestors took up farming some 12,000 years ago because it was a more efficient way of getting food. But a growing body of research suggests that wasn't the case at all.
"We know that the first farmers were shorter, they were more prone to disease than the hunter-gatherers," says Samuel Bowles, the director of the Behavioral Sciences Program at the Santa Fe Institute in New Mexico, describing recent archaeological research.
