谷类里第三要提的是白薯、红薯、山药和土豆等。为什么?原来它“三吸收”:吸收水分,吸收脂肪和糖类,吸收毒素。吸收水分,润滑肠道,不易得直肠癌、结肠癌;吸收脂肪和糖类,不易得糖尿病;吸收毒素,不易发生胃肠道炎症。我在美国也调查了,美国吃薯类是把它做成各种糕点,吃得也不少。希望大家多吃薯类,主食中能搭配薯类。
谷类里面还有燕麦,国外早就知道,中国很多人不知道。你要是血压高,一定要吃燕麦,燕麦粥、燕麦片,因为它能降血脂、降血压。
最后要提的是小米。我们是小米加步枪打的胜仗啊!我回国后问:“为什么咱们现在不吃小米了呢?”很多人跟我说什么:“那玩意不是坐月子吃的吗?”你说糟糕不糟糕?实际上《本草纲目》已经说明白了,小米能除湿、健脾、镇静、安眠。有这么大好处你不吃!
Basically, the most healthy way of eating is to be as close to the diet of human as hunters and gatherers of 10,000 years ago. The modern diet based on farming and has only been around for a few thousands of years -- a short time in human evolution.
So what is the diet of hunters and gatherers like? lots of fruits, vegetables, nuts, lean meat, eggs, fish, (there was no fat pig then!), and little salt (salt was scarce!)
