Medicine can surely help you, but simply put, your body is your primary disease fighter. If you want it to work well, you have to feed it well. Your body needs the right amount of nutrients and vitamins from your diet, which is 100% under your control. According to a study down in Glasgow University of Sweden, obese men have a "60% increased risk of dying from a heart attack than non-obese middle-aged men," demonstrating just one of the many examples of how healthy living can greatly decrease risks of fatal heart conditions and other diseases.
