There's no magic bullet to ward off the effects that the years have on your mind, skin and body, but you can slow the hands of time by eating the right foods. Lack of exercise, smoking and a poor diet all contribute to aging prematurely, but these are all factors that you can control. Increase activity, stop smoking and eat a healthy diet, and you just may turn back the hands of time. Adding foods that are rich in antioxidants, particularly free radical-neutralizing phytonutrients, can reduce your risk of contracting age-related diseases such as cancer, Alzheimer's disease, heart disease and osteoporosis. Foods that reduce inflammation also go a long way in keeping the body young. Cold-water fish, such as salmon, and richly colored fruits and vegetables can work wonders.
