The minimum required data is serving size, carbohydrates per serving, and the amount you want. You can enter other nutrients if you wish and save it to the user database. If you have multiple items for a meal, or have a recipe you want to enter, you can enter the ingredients to get the total carbohydrates. You can save this to the user database with any name you want. The recipe ingredients are shown at the bottom of the screen and saved with the item you save. You can use metric or English units and mix them in a recipe. Most items in the USDA database have weight and volume units as well as descriptions that are not units. A good example is Apples, raw, fuji, with skin which has two descriptions, 1 cup sliced and 1 large. If you select 1 cup sliced, the units will be cup so you can use a measuring cup or tablespoons or liters, while if you select 1 large, the units will be large. You could select 2 large for two apples or 0. 5 large for half an apple. For food items not in the database, you will have to search the manufacturers web site. If you expect to use this food item again, save the food item to the user database which is searched along with the USDA database. A cooking database was extracted from the USDA database and put at the beginning of the search so that if you search for salt, you will find Salt, table near the top of the screen instead of tens of screens later, since the word salt is in many descriptions. There is a miscellaneous database that includes food items and recipes that we have entered for our granddaughter. It does not have all the nutrients or show the recipe for all items.
