Lesson 3 Nutrition for Individual Needs Does it seem to you that everyone has a different idea about proper nutrition? Eating too many carbohydrates is bad for you. Eating meat is unhealthy. In truth, proper nutrition depends on the individual. Lesson 3 Lesson Objectives In this lesson, you will learn to: • Assess the specific nutritional needs of different groups • Describe the proper nutrition for pregnant women, mothers, babies, and young children • Demonstrate health-promoting behavior that will enhance and maintain wellness Lesson 3 Performance Nutrition The Training Diet • The best eating plan for athletes is one that is balanced, moderate, and varied. • Active individuals need to eat more calories from nutrientdense foods to maintain their weight and energy levels when training. Lesson Performance Nutrition 3 Hydration Your body naturally loses fluids through: Electrolytes • Perspiration • Breathing Sodium • Waste elimination Chloride Potassium These fluids must be replaced to avoid dehydration and heatstroke. Becoming dehydrated can lead to an imbalance of electrolytes. Lesson 3 Performance Nutrition Rehydration • Rehydration is important after physical activity and competition. • You must take in as much water and electrolytes as you lose. • Drink 16 ounces of fluid for every pound of body weight lost through sweat. Lesson 3 Performance Nutrition Making Weight When competing in specific weight classes in sports such as boxing or wrestling, always compete at a weight that’s right for you. Losing Weight Athletes should follow a sensible plan and try to lose only one-half pound to one pound each week. Gaining Weight A slow, steady weight gain of no more than one to two pounds per week is recommended. Lesson Performance Nutrition 3 Eating Before Competition Eat three to four hours before competition. Choose a meal that’s high in carbohydrates and low in fat and protein. Drink plenty of water before, during, and after competing. Lesson 3 Vegetarianism Benefits of Vegetarianism People become vegetarians for health reasons, religious or cultural reasons, and environmental reasons. Vegetarians reduce their risk of cardiovascular disease and some cancers by: • Cutting out the saturated fats and cholesterol found in many animal products. • Consuming more fruits, vegetables, and whole grains. Lesson 3 Vegetarianism Meeting Nutrient Needs Vegetarians need to eat: • A variety of incomplete proteins. • Adequate amounts of iron, zinc, and B vitamins. • Adequate amounts of various nutrient-dense foods. Because vegans consume no meat or dairy products, they must obtain vitamin D, vitamin B12, and calcium from other sources. Lesson 3 Dietary Supplements Why Do People Take Supplements? • Eating healthful meals and snacks based on the Food Guide Pyramid can provide you with all the nutrients your body needs. • A health care provider may recommend a dietary supplement to people with certain lifestyles or medical conditions. • Dietary supplements may contain vitamins, minerals, fiber, protein, or herbs. • Supplements can be in pill, capsule, powder, or liquid form. Lesson 3 Dietary Supplements Risks of Dietary Supplements • Taking a megadose can be dangerous. • Claims of herbal supplements, often sold as “natural” nutrition aids, are not based on conclusive scientific evidence. • The Center for Food Safety and Applied Nutrition (CFSAN) of the U.S. FDA alerts consumers to potentially dangerous dietary supplements. • Some herbal supplements known to have dangerous side effects include ephedra, lobelia, yohimbe, and chaparral.
