Meanwhile, our gatherer ancestors ate carbohydrates (polymers of glucose), which was also transported to the liver, via the glycolytic pathway, and broken down for energy. Any excess glucose stimulated the pancreas to release insulin, which transported glucose into peripheral fat tissue, and which also caused the liver to store glucose as glycogen (liver starch).
与此同时，我们的采集祖先吃的是碳水化合物（葡萄糖聚合物），它们也被送到肝脏，通过糖分分解路径分解为能量。多余的葡萄糖会刺激胰腺分泌胰岛素，胰岛素将葡萄糖变为周边脂肪组织，或让肝脏将葡萄糖储存为糖元（肝淀粉）。因此，他们的肝脏也很健康。
