13 Signs Your Body is Deficient in Nutrients

We evolved eating meat, organs, fat, brain, and marrow — the most nutrient-dense foods available. Why this matters: Animal foods provided high energy dense nutrition, fueling brain growth Access to fat and marrow supported larger brains, strength, and survival Less digestion, more usable energy = evolutionary advantage Our biology still reflects this: Stomach acid (pH ~1–2) — similar to carnivores and scavengers Long small intestine — optimized for absorbing fat and protein Short large intestine
