Coffee Drinkers Have Clearer Arteries

Drinking three to five cups a day linked to lower risk of arterial plaque.

July 2015 - Scientists may now better understand at least one way in which coffee could help to protect against cardiovascular disease. A large new Korean study reports that people drinking three to five cups of coffee daily were 41% less likely to show signs of coronary artery calcium than non-coffee drinkers. This calcification is an early indicator of the artery-clogging plaques (atherosclerosis) that cause coronary artery disease, which afflicts nearly 16 million Americans.

Lowest Colorectal Cancer Risk: Vegetarian Diet Plus Fish

Pescovegetarians at even lower risk in new study than vegans.

Eating a more plant-based diet could reduce your risk of colorectal cancer—and especially so if it includes regular consumption of fish. Surprisingly, the latest findings from the Adventist Health Study-2 report that pescovegetarians—people who are otherwise vegetarians but also eat fish at least once a month—were at the lowest risk of such cancers. Adding fish to a vegetarian diet was associated with less risk than any other type of vegetarian diet, including a vegan regimen.

Should You Eat Like a Caveman?

The latest nutrition fad goes back to the Stone Age. Is the Paleo diet a good idea?

Not since the TV-cartoon heyday of Fred Flintsone’s “modern Stone Age family” have cavemen been so in vogue. The Paleo Diet, a book by Loren Cordain, PhD, has been a bestseller since it was first published in 2002, and it has spawned a pile of cookbooks and a glossy magazine devoted to “modern day primal living.” A Google search for “Paleo diet” retrieves 7.7 million hits. Actor Chris Pratt credits the Paleo diet for getting him in shape to star as the buff hero in the Guardians of the Galaxy movie.

How Much Exercise Is Enough?

Two new studies seek the sweet spot for activity and intensity.

Nobody questions the health benefits of even just a little exercise, but you may wonder about what might be called the “Goldilocks” question: How much physical activity is “just right”? And is it possible to get too much or to overdo the intensity? Two large new studies, both published in JAMA Internal Medicine, attempt to answer such questions and identify the “sweet spot” of the ideal amount of exercise.

New Evidence Your Heart Loves Nuts

New Evidence Your Heart Loves Nuts

Two new studies strengthen the scientific link between nut consumption and better cardiovascular health.

If you grew up thinking of nuts as a not-very-good-for-you indulgence, there’s 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.

Are You Keeping Your Brain in Shape?

Staying active may help protect your brains motor functions.

Physical activity helps preserve mobility and motor skills as you age—and not just by keeping your muscles in shape. A new study suggests that activity also maintains mobility by protecting your brain. Even in people with signs of brain aging called white matter hyperintensities (WMH) associated with movement issues, being more active seemed to allow the brain to compensate.
