A compound found in grapes and red wine has been seen to help with age-related health concerns, a new Harvard study has found. When studied on lab mice, the compound, known as resveratrol provided heart benefits, enabling stronger bones and preventing eye cataracts; researchers said on Thursday.

David Sinclair of Harvard Medical School and Rafael de Cabo of the National Institute on Aging placed 1-year-old mice on low-calorie diets and high-calorie diets along with low or high resveratrol doses. The higher resveratrol and higher-calorie diets had similar effects to low-calorie diets and low-resveratrol diets in terms of health benefits

A new study has linked low levels of high density lipoproteins (HDL) or the good cholesterol in middle age to the risk of memory loss that can lead to dementia later in life.

Researchers at University College London and the French National Institute for Health and Medical Research (the French equivalent of the U.S. National Institutes of health) conducted by Dr. Archana Singh-Manoux measured good HDL cholesterol levels of 3,673 55-year-old British civil servants and asked them to memorize 20 words as part of short-term memory test

Watermelon rinds could be the new natural aphrodisiac, new research has shown. Researchers from Texas A&M's Fruit and Vegetable Improvement Center say the fruit's rind can have a Viagra-like effect.
