为什么有人吃豆类食品会胀气?

世事忙忙如水流,休将名利挂心头。粗茶淡饭随缘过,富贵荣华莫强求。

现代人都知道吃点五谷杂粮好,因为营养丰富,不是精加工的食品。从营养学角度来看,各种维生素和矿物质也多,还有一些蛋白质,而不是纯粹的淀粉,总的GI值较低。GI值较低的食品,对现代人控制的心血管疾病是非常有帮助的。

 

不过,有些人直接吃五谷杂粮会胀气。为什么?

 

原因很简单:因为生的豆类(或者一些谷物)含有蛋白酶抑制剂,蛋白酶抑制剂是一种蛋白质,也称抑肽酶。这种蛋白质进入肠胃,抑制了胃液或肠液中的蛋白酶活性,人体就会觉得胀气,因为我们吃进去的蛋白质无法被自己的酶消化分解。当然,另外补充消化酶就另当别论了。

 

解决办法:豆类(或者一些谷物)的种子经过水的浸泡后(种子的自然发芽过程,哟个凉水,不要用开水或凉开水),这些种子就会发芽。当豆类(或者一些谷物)的种子开始发芽后(一点点牙),蛋白酶抑制剂就被分解掉了。再用这样的种子做饭,我们就不会胀气了。

 

那么,豆类(或者一些谷物)的种子浸泡时间是多少呢?

 

荞麦、糙米、黑米,浸泡12小时-24小时;

 

绿豆1天;红豆2天,黑豆3天。

 

最后,给出低GI食品的搭配原则:

 

1,纯蔬菜;

2,蔬菜炒肉;

3,高GI+低GI(谷物+豆类)搭配,蛋白质互补;

4,油炒米饭+鸡蛋(扬州炒饭);

5,紫菜包饭;

6,香菇炒饭。
