Fix Your Diet: Visit MyPyramid.gov

United States Department of Agriculture (USDA) provides a useful website
MyPyramid.gov where you will be able to know the amount of each food
group you need daily. You need to enter your information like age, sex,
activity level etc and you will be able to find out and receive a customized
food guide.

You can receive an estimate of what and how much you need to eat and a
detailed assessment of your food intake and physical activity level. This
also will help you make smart choices from every food group, find your
balance between food and physical activity, and get the most nutrition out
of your calories.

The above-mentioned website is managed by the Center for Nutrition
Policy and Promotion, an organization of the U.S. Department of
Agriculture which was established in 1994 to improve the nutrition and
well-being of Americans. Toward this goal, the Center focuses its efforts
on two primary objectives—
1. Advance and promote dietary guidance for all Americans, and
2. Conduct applied research and analyses in nutrition and consumer
economics.

The Center's core products to support its objectives are the following:
Dietary Guidelines for Americans, MyPyramid Food Guidance System,
Healthy Eating Index, U.S. Food Plans, Nutrient Content of the U.S. Food
Supply, Expenditures on Children by Families.
