Reputable sources for nutritional information charts include the U.S. Food and Drug Administration's labeling and nutrition webpage, the United States Department of Agriculture's Food-A-Pedia and the Calorie King's food database. For example, the FDA offers downloadable, printable posters of charts that contain nutrition information for raw fruits, vegetables and fish.
The USDA's Food-A-Pedia enables users to search by keyword through a database of over 8000 foods. It also allows users to compare two foods. Calorie King's database is organized by category but also allows for keyword searching. It contains a wide range of categories, including basic food groups such as "Grains & Flour" and "Eggs, Meats, Poultry, Seafoods," as well as special groupings, such as "Fast-Foods, Fair Foods, Eating Out, Restaurants," and "Alcoholic Beverages."
