A variety of government-sponsored webpages include calorie charts or calorie trackers, such as the United States Department of Agriculture National Nutrient Database and Choose My Plate. The entries on these websites also include nutritional information such as fat content, nutrient content and fiber content.
The National Nutrient Database is a comprehensive list of foods and ingredients. It contains a list of over 8,000 different foods. Visitors can either scroll through the list, which is organized alphabetically by food group, or search for specific foods. By clicking on a food, visitors can pull up a full nutritional profile including calorie counts for specified amounts, vitamins, minerals, carbohydrates and fats, according to USDA.gov.
Choose My Plate is a website developed by the USDA Center for Nutrition Policy & Promotion. It not only gives information about the nutritional content of different foods, but also helps Americans make healthier food choices. It helps people build healthy meals by food group and includes plenty of information on daily nutritional recommendations and serving sizes. Website users can sign up to the website's SuperTracker feature for free to track their calories and activities and set personal goals.
A number of commercial websites also include calorie charts and trackers. For example, the NutritionData section of Self magazine's website includes nutrition and calorie facts for a large database of foods, a daily requirements calculator and a recipe analyzer tool.
