Document Summary

Tibetans have 15+ gene mutations for oxygen use compared to han. Helps them use smaller amounts of oxygen efficiently. Andean highlanders = more oxygen-carrying hemoglobin to their blood. These changes are irreversible based on where you grow up. Increased red blood cell (rbc) production to carry oxygen. Vasodilation does occur, but to carry oxygen to skin, not release heat. Balance of carbohydrates, fats, proteins, vitamins, and minerals. Kwashiorkor bloated stomach in children caused by lack of protein even when child consumes enough calories. Lactose = complex sugar found in milk and milk products. Most mammals stop producing lactase after they are weaned off breast milk. Lactase persistence allele = continued production of lactase. Most common in populations that domesticated dairy animals . North europe and some places in middle east and africa. Is a cultural construct, not a biological reality.
