Diet and exercise have quite different roles in health, but people often misunderstand them. The role of diet in health is to provide essential nutrients and energy to allow normal metabolic regulation. The role of exercise beyond daily activities is controversial, but it is known that too much exercise is detrimental to health because it is a form of stress. Therefore diet is directly related to health, but exercise is only tenuously related to it. Many assume that a poor diet can be compensated for by performing strenuous physical activity, but this is clearly not true as no essential components can be supplied by exercise. Many also assume that exercise can reverse weight gain caused by low quality diets, but again thus is not the case. The cornerstone to good health is a high quality diet in combination to minimal exposure to chronic stress. Exercise can facilitate health and is particularly beneficial to mental health. However, the amount of exercise required for health is probably no more than is required to perform normal daily tasks.
