A Good Nights Sleep Boosts Your Healthy Diet and Lifestyle

Getting a good nights sleep is good for more than just feeling perkier the next morning. Studies have shown that adequate sleep contributes to healthier blood pressure, cholesterol and triglyceride levels. On the other hand, people who fall short in sleep hours are more likely to be overweight or obese and to be diagnosed with hypertension.

Green Tea Protects Brain Cells

A flurry of new studies is raising hope that green tea may someday be a potent weapon in the fight against Alzheimers disease and other forms of dementia.

Dehydration Affects Your Mood

Dehydration has long been known to compromise physical performance. Now, a new Tufts study provides insight into the effects of mild dehydration on young athletes, and possibly into the lives of people too busy to consume enough water daily. About 30 male and female Tufts students were assigned to either a dehydration group not given fluids during athletics, or a control group that was given water. Participants weighed in before and after athletics to assess body water loss. After athletic activity, participants underwent cognitive tests, which included short-term memory and mood scales.

Ginkgo Strikes Out Against Cognitive Decline

New results from the largest-ever clinical trial of ginkgo biloba add to the mounting evidence that Americans who spend $250 million annually on the herbal supplement are probably wasting their money: Researchers conducting the Ginkgo Evaluation of Memory (GEM) study report that twice-daily doses of 120 milligrams of ginkgo extract did no better than a placebo in slowing older adults rate of cognitive decline. Earlier GEM findings had debunked ginkgos purported protective benefit against Alzheimers and overall dementia, as well as most cardiovascular benefits (see the February 2010 Healthletter).

Trans Fats Tied to Depression Risk

Could trans fats be making you blue-and not just because of their dangerous effects on your heart health? A new Spanish study of more than 12,000 men and women reports that those consuming the highest level of trans fats were 48% more likely to suffer from depression. People consuming the most healthy poly- and monounsaturated fats, on the other hand, saw a lower incidence of depression
