[Labelling and composition of food, basic aspect in the update of the food composition tables].

Food and beverage composition tables are a crucial element for determining nutrient intakes from the dietary records of foods and beverages. Knowing their composition and how they are updated is an essential mechanism for reliably providing real data on these intakes, otherwise it could be the case that current food and beverage consumption would be reflected in nutrient conversion with information on ingredient composition and nutritional value from 5, 10, 15 or 20 years ago, with the resulting deviations in the interpretations, especially in macronutrients, from the existing reality.
