In the FAO (Food Agriculture Organization) web site: Nutrition and consumer protection (1) there are several recommended web sites about software food information , in one of them we can make calculations nutritional. You can access via the link: Self nutrition data (2).
We can calculate our BMI and know the calories and nutrients that give us the food and even recipes for food.
