How do you fatten a cow? Feed it grains… How do you fatten a human? Feed it grains.
Grains include everything from wheat and barley to corn, oats, rice, rye, and sorghum. Despite what conventional wisdom tells you, grains are far less nutritious than vegetables, fruit, nuts, seeds, and animal foods.
Do whole grains contain nutrients like the high-carb propagandists proclaim? Technically, yes, grains contain some nutrients. But due to the presence of anti-nutrients and enzyme inhibitors, your body cannot adequately absorb them, rendering them essentially useless. So no, grains do not contain bioavailable nutrition like vegetables and fruits do.
