People with type 2 diabetes get an earful of grim lectures about their health prospects and endure much hardship to manage their condition well. But new research offers a rare reward to those who do: A glass of wine every day not only won't hurt - it may actually improve cardiac health, help manage cholesterol, and foster better sleep.

The new study, published in the Annals of Internal Medicine, found that compared to a nightly glass of mineral water, a single glass of wine - red or white - offered those with well-managed type 2 diabetes some benefits. After two years, those who drank a glass of white wine nightly improved their triglyceride levels compared with those who had water or red wine.

But red wine's benefits were far more numerous and more pronounced than those of white. Among them: a nearly 10 percent increase in HDL ("good") cholesterol and improved levels of APOA1, a measure of lipid metabolism. - Los Angeles Times
