Many calorie and nutrition lists are available on the Internet, including those at CalorieKing, the Agricultural Research Service of the U.S. Department of Agriculture, What's Cooking America and NHS Choices. Also available are calorie calculators which allow one to input amounts of food or ingredients to end up with a final calorie count.
CalorieKing provides calorie listings by food category, including such categories as alcohol, breakfast bars, snacks, desserts and dairy foods. In addition, the site offers calorie counters for many restaurants, fast food providers and other branded foods, including Olive Garden, Trader Joe's, Dairy Queen, Subway and Wendy's.
The U.S. Department of Agriculture's Agricultural Research Service provides calorie details for foods categorized by food group, including beef products, dairy products, fruits, nuts and seeds, and sausages and luncheon meats. In addition, they also provide calorie counts for Native American foods. To use the database, a visitor enters one or more terms, receiving a page that lists the search item’s nutritional information, including calories. For example, after a search for blue cheese, the nutritional values for blue cheese are delivered in several serving-size options, including values per 100 grams, per ounce, per cubic inch and per cup. When reading the table provided for blue cheese on the USDA website, the calories are listed under the Proximates section in the same line with energy and rendered in kcal units.
What's Cooking America offers a detailed calorie count chart in which foods are easily findable in alphabetical order. Their chart provides carbohydrate and fat gram counts for each food as well as calories.
The United Kingdom's NHS Choices website offers a searchable database of over 150,000 foods. The foods listed include brand name foods as well as raw ingredients. Each food listing includes fat grams as well as calories, and a built-in calculator allows a recalculation of calories when a serving size changes.
