How Do You Find the Nutritional Values of Different Foods?


Quick Answer

Find nutritional values for any packaged food sold in the United States by looking at the Nutrition Facts box on its label; for fresh or non-packaged foods, websites such as CalorieKing.com and the U.S. Department of Agriculture's National Nutrient Database for Standard Reference are good places to check. These websites give information about the vitamins, minerals, fats, carbohydrates and other elements in most foods.

For packaged foods, the Nutrition Facts box on the label tells you how many servings are in the package, what size each serving is and how many calories are in each serving. Information about how many calories are derived from fat is provided as well as the total fat content and data about levels of saturated and trans fat in the food. Next in the list are the food's carbohydrate, sodium, fiber, sugar and protein content. The bottom of the box has a listing of the daily percentages of vitamins A and C, calcium and iron contained in the food.

Fresh and non-packaged foods are not labeled with a Nutrition Facts box, but it is still easy to learn about their nutritional value. On the USDA National Nutrient Database for Standard Reference website, begin by clicking on the Start Your Search Here button. Next, enter the name of the food you want to learn about, and select it from the drop-down menu that appears. You can then indicate the portion size you want to know about and view detailed data on the food. You can also browse categories of food instead of searching for one item in particular.
