Who Brought Us Cow Milk?

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…

Eat your Green Vegetables–To Enjoy the World!

There is an old probe from China says “Eye is the window of your soul.” That’s true and our eyes actually do a lot of things for us every day. For an average adult having a job, ideally he or she can get 8 hours sleep–and that is the only time your eye literally get rest. Our eyes are so precious. Every time I watched movies about blind people, I would imagined what my world will be if I lose my eye sight–I lose the beautiful landscape, I lose the ability to seeing my toots, and I lose my ability to live well.

Age-related Macular Degeneration (AMD) is the leading cause of visual loss for people older than 60. Plus, so far there is no cure for this disease. It is a very common eye disease in older population. For people age from 80-89, 35% of them have AMD. This disease is caused by over exposure of oxidative stress since our eye has very high consumption of oxygen to keep functioning.

For everybody else who still want to enjoy the beautiful world even when we are old, what can we do? –Don’t forget a golden truth: Prevention is better than cure. Though we can’t treat the illness so far, we can definitely prevent it. Fortunately, scientists found out the prevention can be easily done by something you have been encouraged to do for a long time–eat more of the green leafy vegetables!

Naitonal Institute of Health conducted a “Age-Related Eye Disease Study” to test certain the effect of certain nutrients for preventing AMD. They chose vitamin C and E, β-carotene, zinc, copper, lutein and zeaxanthin for the trial and found that all the nutrients can to some extent contribute to prevent the AMD, especially for lutein and zeaxanthin. The risk of getting AMD is 57% lower in the group who took lutein and zeaxanthin compared to the control group (not taking any extra nutrients).

Lutein and zeaxanthin are antioxidants naturally mainly found in green leafy vegetables. Basically, for vegetables, the more you eat, the more health benefits you can get. And here is a list of vegetables rich in lutein and zeaxanthin:

Well, before reading this article, you might have been encouraged to eat more cups of vegetable because it is good for your heart, your weight control, your blood pressure or other things. If you didn’t make up your mind to start to do so, treasure your ability to see all the beauties in the world and do something for it!
