The preponderance of articles and research on nutrition can be confusing. The active woman over 30 can enhance performance and health with a high-quality diet. Specific nutritional concerns for women after the college years, such as nutrient content, iron, calcium, vitamin supplementation, and caffeine are discussed. Evidence that processed foods and fast foods contain high percentages of fat are presented. Training and nutritional patterns of 47 women who participated in the Hogeye Marathon (Arkansas) indicated that most of these women exercised an average of 20 plus miles per week and consumed an average of 1,900 calories daily. Few, because they were regular exercisers, were overly concerned about their weight. Results indicated that most of the surveyed women consume quality diets designed to enhance their performance.
