Alcohol Intake Lowers Risk of Heart Disease But … Increases Risk of Breast Cancer?

A study published this week in the Journal of the American Medical Association suggests that even moderate alcohol consumption — as little as one-half to one drink per day — increases a woman’s risk of breast cancer by about 15% [1]. Daily consumption of two or more drinks per day (where a “drink” contains about 14 grams of pure alcohol, and results are independent of the type of drink consumed) increases breast cancer risk by 50%. These results suggest a much stronger effect of low to moderate alcohol consumption on lifetime breast cancer risk than previous studies [2-4] have done.

Exercise Intensity, Not Quantity Reduces Risk of Death from Heart Disease

New research suggests that the intensity of exercise might be more important than the quantity in helping to prevent death from heart disease and other causes.

In a study presented last week at the European Society of Cardiology Congress 2011, scientists described new research that examined the relationship between exercise duration, exercise intensity, and total risk of death [1]. Lead researcher Peter Schnohr of Copenhagen, Denmark explained that both male and female cyclists had a decreased total risk of death if they cycled vigorously (by their own perception), but that cycling duration didn’t show a similar protective effect.
