The nutritional elements appropriate for contemporary humans reflect genetically determined biochemical and physiological factors, which have evolved over hundreds of millions of years. Stone Age humans, however, derived nearly all of their nutrients from just two of the four major food groups we select from today.
适合当代人类的营养元素反映了由基因决定的生物化学和生理因素，这些因素已经进化了数亿年。然而，石器时代的人类几乎所有的营养都仅来自于我们如今从四大食物类别中选择的两类。
