"I know what I should
eat. I just don't do it." This is heard everyday by people struggling
to juggle work, workouts, family and friends, food and nutrition.
The trick is to grab the foods
that support your sports program and enhance your health. Food is the fuel
composed of important nutrients essential for maintaining optimal health
and top performance.
The six nutrients for health
are:
- Carbohydrate - this fuels your muscles and brain. They are
the primary energy source when you're exercising hard. You should get 60%
of your calories from carbohydrate-rich foods such as fruits, vegetables,
breads, and grains.
- Fats - this is a source of stored energy (calories)
that we burn primarily during low-level activity, such as reading and sleeping.
Vegetable fats are generally unsaturated and less harmful than animal fats,
which are saturated. You should limit your fat intake to about 25% of your
daily total calories.
- Protein - these are essential for building and repairing
muscles, red blood cells, hair, and other tissues, and for synthesizing
hormones. Protein is a source of calories and can be used for energy if
inadequate carbohydrates are available such as during a strict diet or
exhausting exercise. About 15% of your calories should come from protein-rich
foods such as fish, chicken, and dried beans.
- Vitamins - these are metabolic catalysts that regulate
the chemical reactions within the body. They are not a source of energy
(calories).
- Minerals - these combine in many ways to form structures
of the body and regulate body processes. Minerals do not provide energy.
- Water - an essential substance that makes up about
50 to 55 % of your weight. Water stabilizes body temperature, carries nutrients
to and waste away from cells, and is needed for cells to function. Water
does not provide energy.
The United States government
has established the Recommended Dietary Allowance (RDA) as a standard for
nutrient intake. These recommendations for vitamins and minerals meet or
exceed the needs of nearly all people, including athletes.
