title: Nutrition of the older athlete.
abstract: Nutritional needs and dietary goals of the older athlete involve meeting basic physiologic requirements of aging and exercise, promoting weight control, and incorporating guidelines for reducing the risk of chronic disease. Conservative dietary approaches to weight loss in the obese patient and a high-carbohydrate diet for maximum exercise performance are sound approaches, although diets often need to be individualized. Recent dietary recommendations to reduce fat and increase fiber can be applied without risk of compromising nutritional status for most patients. Guidance away from extremes in caloric restriction and in the distribution of calories may help to promote health and the maintenance of exercise activities. Although requirements for certain micronutrients are affected by aging, vitamin and mineral supplements are unlikely to be necessary for healthy adults and should meet basic criteria for safety if they are prescribed. Diet sources of calcium may require attention, although iron requirements are reduced among postmenopausal women when compared with younger athletes. Adequate fluid replacement is essential for athletes of all ages. For the older athlete who is competing in high-intensity endurance exercise, evidence for the usefulness of 4% to 10% carbohydrate-containing sports drinks exists. Little evidence supports the use of ergogenic aids, such as supplements and unusual food products. Resources and personalized guidance from a registered dietitian can be helpful for many older athletes.
