Don't pass on dairy

If you take your coffee black, you're pretty badass. It takes a certain type of person to chug that stuff down without some milk to take the edge off. However, unless you're getting your dairy from other sources, you may want to reconsider this decision and add a splash of milk to your java.

Harvard researchers found that women who consume little or no dairy as part of their daily diet are 11 percent more likely to develop high blood pressure than those who ate at least two daily servings. So, if you're still hellbent on taking your coffee black, try to include a half cup of low-fat cottage cheese or a cup of yogurt to your diet at least twice a day.

The research, published in a 2007 issue of Hypertension from the American Heart Association, is based on data from food questionnaires filled out by 4,797 participants in the National Heart, Lung, and Blood Institute's Family Heart Study, in association with the Harvard Medical School.
