Research Backs Blueberries Heart Benefits

Blueberries have earned their reputation as a superfruit in part because of their high content of antioxidant polyphenols. (In fact, of course, theres no such thing as a superfruit-all fruits have some super qualities.) New research put those polyphe-nols to the test against metabolic syndrome, a complex of conditions, including central obesity (high waist-hip ratio), high blood pressure, high serum cholesterol and insulin resistance, that increases the risk of heart disease and diabetes.

Vitamin D Might Help Ward Off Diabetes

The so-called sunshine vitamin, proven to be important in bone health, has lately been linked to possible benefits against a wide range of diseases.

Low in B Vitamins? Depression May Be Lurking

Previous studies have suggested that B vitamins might help protect against depression, but these were mostly snapshots at a single point in time. Now a new study connects B-vitamin intake among 3,503 seniors, initially free of depression, over a span of 12 years: For every 10-milligram increase in daily vitamin B6, risk of developing depression declined by 2%. The same was true for every additional 10 micrograms of vitamin B12.
