More evidence that coffee - once thought of as bad for you - is not only safe in typical amounts but might actually help protect your health comes from a new study of colorectal cancer risk. Researchers compared 5,145 patients who had been diagnosed with colorectal cancer within the past six months with a control group of 4,097 men and women with no history of the cancer. Drinking one or two cups of coffee a day was associated with a 26% lower risk of developing colorectal cancer, with risk dropping even more as consumption increased.
Two new studies provide important evidence of how physical activity might reduce the risk of Alzheimer's disease and other forms of cognitive decline. One study reported that participants who were most active showed the least decline - the equivalent of 10 years of mental aging. In a second study, the most active older adults were found to have the largest volume of gray matter in brain regions typically affected most by Alzheimer's.
Continuing to exercise as you age really can make a difference. Researchers reported in the journal Circulation that even people in their 70s have much lower risk of stroke and heart attack with regular moderate exercise such as walking.
Every cell in your body needs water to function. Water transports nutrients and oxygen throughout the body, and carries away waste materials. Water makes up most of your body, ranging from about 75% of body weight in infancy to 55% of body weight at older ages. Your brain and heart are almost three-quarters water, your muscles and kidneys are almost 80% water, and even your bones are about 30% water.
The number of Americans newly diagnosed with diabetes fell for the fifth straight year in 2014, according to new data from the Centers for Disease Control and Prevention.
Science continues to prove Hippocrates right when he said, "Walking is man's best medicine." If youre beginning to lag on your New Year's resolutions, or that Fitbit you got for Christmas is gathering dust, a trio of recent studies provide incentive to get up off the couch and lace up those walking shoes.
That extra cup of coffee is not only safe for most people, but might actually reduce your risk of dying prematurely from heart disease and several other causes.
The good news is you might live longer than you expect. The bad news is that such inaccurate estimates could cause you to skip lifestyle changes that can make your remaining years healthier and more independent.
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.
As a regular reader of this newsletter, you know to pay attention when a five-year clinical trial with more than 3,000 participants reports no benefits from omega-3 supplements against cognitive decline. Such a study - one of the largest and longest of its kind - would seem to slam the door on hopes for brain benefits of fish-oil pills. But before you go searching for the receipt on the last batch of omega-3 supplements you bought, Tufts experts have a couple of caveats.
