Buy Xenical online - Health Eating Index
August 1, 2009 – 2:41 pmNutrition plays a vital role in the prevention of chronic diseases such as
coronary heart disease, hypertension, and diabetes. The Healthy Eating
Index (HEI) is a measure of the overall quality of an individual’s diet. It was
developed by the U.S. Department of Agriculture (USDA) to assess how
well American diets comply with the 2000 Dietary Guidelines for Americans
and the Food Guide Pyramid.
The HEI measures the intake of ten dietary components to provide a
single score out of a possible 100 points. A diet with a score greater than
80 is considered “good,” one with a score of 51-80 is considered “fair,” and
one with a score of less than 51 is considered “poor.” Each component con-
tributes equally to the overall score.
Components 1–5 assess how well an individual’s diet complies with the
Food Guide Pyramid serving recommendations for the Grain, Vegetable,
Fruit, Milk, and Meat Groups. Recommended servings for each food group
are calculated based on diets containing 1,600, 2,200, and 2,800 calories
per day. Components 1–5 have a maximum of 50 points, with 10 coming
from each food group. A score of zero is assigned to a group if no items
from that category are consumed. Intermediate scores are calculated pro-
portionately to the number of servings consumed
Component 6 assesses total fat consumption as a percentage of total
caloric intake.
Component 7 assesses saturated fat consumption as a percentage of to-
tal caloric intake.
Component 8 assesses total cholesterol intake. It is recommended that
individuals consume no more than 300 milligrams of cholesterol daily.
Component 9 assesses total sodium intake. Individuals should ideally
consume no more than 2,400 milligrams of sodium daily
Component 10 assesses variety in the diet. While there is agreement
that individuals should eat a variety of foods daily, there is no consensus of
how to measure variety.
