A new study finds both low and high intensity workouts help with weight-loss, but only high intensity workouts also help fight diabetes. Canadian researchers divided 300 obese people into two groups – one did short, high-impact exercise five times a week, the other did less strenuous physical activity. All participants showed smaller waistlines, but only the high intensity group also lowered their glucose levels. SOURCE – Annals of Internal Medicine/

Breast density
Many women don’t know enough about breast density, according to a new report from the Mayo Clinic. Increased breast density is linked to a higher risk of breast cancer and can make it more difficult to spot cancers in mammograms. But according to the study, only about half of women surveyed knew that breast density affects breast cancer detection and that it’s related to cancer risk.

Coffee
There’s more evidence drinking coffee can help your heart. Research in the British Medical Journal shows people who drank 3 to 5 cups of coffee a day had less calcium build-up around their arteries than people who drank fewer than 3 cups a day. Calcium build up increases the risk of blood clots . But too much coffee isn’t good either. People who drank more than 5 cups had the highest levels of calcium build-up. SOURCE – BMJ/MedDay/CBS
