Foods can be further divided into up to eight groups, depending on how detailed we want to be. Because of this, national dietary recommendations may differ globally in terms of the foods consumed, but generally speak, nutrient requirements are very similar.
Therefore, Grain, dairy, vegetables, fruits, and proteins are thus important. Brussel sprouts or a salad, cantaloupe or strawberries, cheese, bread, milk, and trail mix are a few examples.
