Matti Narkia on 25 Nov 09Plant-animal subsistence ratios and macronutrient energy estimations in worldwide hunter-gatherer diets. Cordain L, Miller JB, Eaton SB, Mann N, Holt SH, Speth JD. Am J Clin Nutr. 2000 Mar;71(3):682-92. PMID: 10702160 Our analysis showed that whenever and wherever it was ecologically possible, hunter-gatherers consumed high amounts (45-65% of energy) of animal food. Most (73%) of the worldwide hunter-gatherer societies derived >50% (> or =56-65% of energy) of their subsistence from animal foods, whereas only 14% of these societies derived >50% (> or =56-65% of energy) of their subsistence from gathered plant foods. This high reliance on animal-based foods coupled with the relatively low carbohydrate content of wild plant foods produces universally characteristic macronutrient consumption ratios in which protein is elevated (19-35% of energy) at the expense of carbohydrates (22-40% of energy).
