Exercise improves cardiovascular health, lowers blood pressure, helps control body weight and contributes to a healthy immune system. Aim for at least 150 minutes of moderate exercise each week, or 30 minutes a day for 5 days a week. Remember that some activity each day is much better than none.

Adequate nutrition can supply the recommended intake of vitamins and minerals, but some people may benefit from supplementation.
