A newly published followup to findings from a study of the so-called Mediterranean diet adds to the evidence that such an eating pattern, especially when it includes nuts and olive oil, may help protect the aging brain. Results from a subgroup of the Spanish PREDIMED study showed that those assigned to a Mediterranean diet held steady in cognition while a control group declined. While previous observational studies have linked a traditional Mediterranean-style dietary pattern to cognitive protection, this is the first such evidence from a large randomized clinical trial.
Q. Is there a recommended ratio of omega-3 fatty acids to omega-6, which I read can cause inflammation?
Americans consume more than $7 billion a year worth of yogurt, with hundreds of new yogurt products introduced annually. In survey after survey, consumers say the healthfulness of yogurt is top among the reasons they eat it.
If you grew up thinking of nuts as a not-very-good-for-you indulgence, theres a growing pile of evidence that should change your mind about these healthy foods. For a long time, consumers thought that coffee raises blood pressure, eggs cause heart disease, chocolate is an unhealthy treat, and nuts make you fat, says Jeffrey Blumberg, PhD, director of Tufts HNRCA Antioxidants Research Laboratory. However, such conclusions were often based on very little science and several mistaken assumptions. The latest news in nuts rehabilitation comes from two studies spotlighting the heart-health benefits of almonds and peanuts.
With the domestic blueberry season about to begin, theres no better time to celebrate the bountiful health benefits of Americans second-favorite berry (after strawberries). New research has linked blueberry consumption to better blood pressure, and Tufts scientists continue to explore how blueberries protect the brain. More than three-dozen current clinical trials are testing blueberries possible benefits for vision, gout protection, arterial function, blood sugar and more.
Bugs Bunny, always depicted munching on a carrot, may have been onto something. Researchers have found that carrot consumption not only helps insure an adequate intake of a variety of important nutrients and fiber, but may also reduce your risk of chronic disease.
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.
Are organic fruits, vegetables and grains better for you? No one disputes that organic foods are lower in synthetic pesticides, though how important that is to your health remains controversial, as long as levels fall below EPA thresholds. But most studies have found little difference between organic and conventionally grown crops in nutritional value.
Proponents of resveratrol, the antioxidant compound found in red wine and grapes whose near-miraculous health claims have created a $30 billion supplement industry, must have felt a bit of whiplash lately. First, a new study of dietary intake of resveratrol in the Chianti wine-making region of Italy made headlines by reporting no correlation with longevity or lower risks of cancer or cardiovascular disease. Resveratrol Health Benefits a Myth?, one news article asked. Then, just three weeks later, another new study reported that resveratrol supplements improved memory in overweight older people-raising hopes once again.
A small clinical trial suggests that green tea could improve the connectivity between parts of the brain involved in tasks of working memory. You might think of working memory as the brains sticky notes, where bits of information are temporarily held for manipulation before forgetting or transferring to long-term memory.
