Grains vs Milk

"It's also important to consider the big picture when judging the suitability of various foods. It helps to tell stories about the food we eat, to think about narratives. Grains aren't just little morsels of protein, carbs, and fiber bred for our enjoyment. They are baby plant eggs. Those macronutrients are there to sustain the seed's growth and those micronutrients are there to protect it. They are the plant's lifeline to immortality. They are literally shaped by the hand of evolution to survive and ravage the digestive tract of the poor sap that swallows them and discourage further consumption. Grain is only food because we deemed it so. Dairy? Dairy is objectively, absolutely food. Its fat, protein, and carbs are there to be consumed, albeit by young cows, sheep, and goats. It's meant to spur growth, to pack on muscle and fat and weight. And yeah, eating dairy protein causes an insulin spike, but that can be useful if you know what you're doing." -- http://www.marksdailyapple.com/dairy-insulin/
