6. Have a glass of wine with dinner (just one)
One study found that women who had a glass of wine a day cut their risk of diabetes in half compared with teetotallers. (Not a wine lover? The same effect was found for beer.) But cork the wine once dinner is over. An Australian study found drinking a glass of wine immediately after eating can result in a sudden drop in the insulin in your blood, meaning the glucose from your meal hangs around longer, eventually damaging the arteries.
