Main fuel source for the body.

60% of diet for Athletes

Simple: honey, candy, pop, sports drinks, fruit

Complex: breads, potatoes, bagels, cereals, beans, veggies, nuts, seeds, pasta

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

Saturated vs Unsaturated fats

Athletes should stick to

“healthy” unsaturated fats

WHAT AN ATHLETE’S PLATE SHOULD LOOK LIKE (BALANCED DIET)

During exercise <60 min

During exercise >60 min

MONITORING HYDRATION

“WUT”

W= Body Weight

U= Urine Color

T= Thirst

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

VITAMINS ATHLETES NEED CONT.

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

Pantothenic Acid: breakdown foods for usable energy

Poultry, seafood, nuts, seeds, avocados, whole grain

Biotin: energy productionNuts, eggs, soybeans, fish

D: hormone, not a vitamin; bone healthFortified milk and cereals, cod-liver oil, seafood, eggs, SUN!

MINERALS

functionShould get adequate amount

through a balanced diet

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.
