Nutritional needs depend on many parameters: gender, level of physical activity, age, weight and height.
With these data, food nutrients calculatorestimates your recommended daily nutrients intakes.
Important note : this is only an estimation! Please do not respect blindly the figures on this site, but rather consider them as a good rule of thumb.
