I have been thinking and googling for a couple of days on a couple of questions:
Who was the first guy drank cow milk? When did that happen? What was the driven force?
The answer is: no one knows that so far! But whatever, I like to give my great honor to the cow milk discover man. He or she found an excellent, or to some point can’t be replaced, source of calcium and vitamin D for modern diet. There is no doubt that human civilization took place with dramatic changes of large discoveries, and with all the great changes human become more and more intelligent (to some extent we are over clear).
I have an imaginary scenario in my mind: before human began drinking cow milk, we depended on other foods (meat, veggies, grains), which can provide enough protein, fat, and sugar for our metabolic functions. Our ancestors might not get much vitamin D from the diet, but their bone were prone to be stronger–because they had a more active lifestyle with more sunlight exposure. Sunlight gave them the most vitamin D.
Well, some people have the idea that what their grandparent ate might be better than today’s common diet–since they can live healthily , we don’t need changes. Since human didn’t live with cow milk form the start, can our population live without cow milk now? Nope, unfortunately–since our life style had dramatic changes, we sit longer, we play less, we drive more, we walk less, we stay indoor more, we get less sunshine. Our bone and thus the whole body skeleton need the compensation from food.
Let’s drink the milk, exercise more, and go outside! Getting stronger bone helps you to enjoy your life–to be continue…
