WHICH IS BETTER FOR ATHLETES?
COMPLEX CARBOHYDRATES
Consist of a chemical structure that is made up of three or more sugars
Rich in fiber, vitamins and minerals
Act as the body's fuel, and they contribute significantly to energy production
Should be consumed before a practice or game
PROTEIN
Made up of amino acids
Body uses amino acids to form new
tissues and repair damaged tissues
Younger athletes need it more than older to promote growth
Last source of energy used by the body
Meat, beans, nuts, dairy products, fish, eggs
FATS
A NECESSARY COMPONENT OF A HEALTY DIET
Helps cells function properly
Required for metabolism of some vitamins
Helps to maintain a normal body shape

VITAMINS
Substances that help the body perform specific functions (help regulate metabolic processes)
Should be able to meet vitamin needs through a healthy, well balanced diet
Supplements available
VITAMINS ATHLETES NEED
B1 (Thiamine): breaks down carbs and proteins for energy
Whole and enriched grains, fortified cereals
B2 (Riboflavin): energy production, red blood cell formation
Almonds, milk, yogurt, wheat germ, fortified breads and cereals
Niacin: supports anaerobic and aerobic performance
Meat, fish, poultry, peanuts, peanut butter and enriched grain products

B6: production of energy and hemoglobinMeat, fish, poultry, eggs, beans, whole grains, seeds and oysters
B12: red blood cell formationONLY ANIMAL PRODUCTS: seafood, meats, milk and cheese, eggs, fortified breakfast cereals
Folate: cell production and heart healthEnriched grains, dark leafy greens, whole-grain breads and cereals, citrus fruits
VITAMINS ATHLETES NEED CONT.
C: protecting from infection, produce collagenCitrus fruits, strawberries, sweet peppers, tomatoes, broccoli and potatoes

SPORTS MED NUTRITION PROJECT
For this project you will be assigned to a popular supplement or herb to research. You should research what the product claims to do, what are the benefits of the product, what are the risks/side effects and how can this be found naturally. You will then create a poster (provided by Mrs. Brown) and present your findings to the class. You will work with a partner.
