As a consequence, people today have widely varying nutrient requirements, especially with regard to macronutrients (minerals) – the proteins, carbohydrates, and fats and oils that are the fundamental “building blocks,” that is, the compounds most essential to life.

For example, many people native to and who currently inhabit tropical or equatorial regions have strong hereditary need for diets high in carbohydrates such as vegetables, fruits, grains and legumes. These foods provide the kind of body fuel that is most compatible with the unique body chemistry of people who are genetically programmed to lead active lifestyles in warm and humid regions of the world. Their systems are simply not designed to process or utilize large quantities of animal protein and fat.

Conversely, people native to and from cold, harsh northern climates are not genetically equipped to survive on light vegetarian food. They tend to burn body fuel quickly, so that they need heavier foods to sustain themselves. For example the Inuit (Eskimo) can easily digest and assimilate large quantities of heavy protein and fat – the very type of foods that would overwhelm the digestive tracts of people from, say the Mediterranean basin.

The bottom line is that a diet considered healthful in one part of the world is frequently disastrous for people elsewhere in the world.

Note: a very comprehensive questionnaire sorts out and identifies 3 basic types; protein dominanat, carbohydate dominant and balanced. Clinically one has yet to find a more program with better outcomes for the patient
