Roger is a starting guard on his college basketball team. He is a leader on his team, stays after practice to work on his shots, and is busy with academic and community life on campus. Because of his hectic schedule, he has little time for meal planning, grocery shopping, and food preparation. Dinner is usually consumed at the athletic training table during the week, and the rest of his meals are consumed either at home or at local restaurants. A 3-day food record kept by Roger recently was analyzed using a nutrition software program. The analysis revealed he is not meeting his estimated needs for Vitamin A, C, D, and B12--in fact, they were relatively low. Please explain to Roger how his low intake of Vitamin A, C, D and B12 may affect his athletic performance and overall health. 2. Provide recommendations to improve his dietary intake of Vitamins A, C, D and B12.
