Simply enter a food by name or keywords (e.g. chicken breast, tomato soup) and click the GO button. The search results will be organized by category to simplify finding the item you are looking for.
Find foods by their calorie density. Calorie density is the amount of calories in one gram of the item. Items containing 0 calories will have the lowest density (e.g. diet drinks) and items that are very high in fat will have the highest density (e.g. lard).
Find foods by the ratio of calories derived from Carbohydrates, Protein and Fat. Just slide the bars between the three sections to customize the search. When you have the percentages lined up select GO!
