The needs of people have always been the same. Calories ingested must equal the calories expended, or starvation sets in. Protein, carbohydrates, water, vitamins and minerals must be ingested on a regular basis. Different groups of people gather different foodstuffs to satisfy their need for calories based upon their geographic location, and the materials available for assimilation.
i dont know what you mean by different "groups" of people, but i do know that all people need the numerous vitamins, minerals, and nutrients for a body to thrive. There are, of course, the food groups, which include grains, dairy, veggitables, fruits, meats and poultry, and fats and oils, but it's not so much the food we need as what's in it. we need protein, for example, just like the alphabetical vitamins, iron, calcium. etc.
