大豆的蛋白质含量高达35%-40%,1公斤大豆的蛋白质相当于2公斤瘦肉或3公斤鸡蛋或12公斤牛奶的蛋白质含量。尤其有益的是,大豆不含胆固醇,对于大脑极为有益。研究表明,大豆经水泡、磨碎,充分加热制成豆浆后,营养吸收率高达90%,豆浆以其均衡的营养成分、细腻的口感、食用方便一直受到中国人的喜爱,并逐渐被世界上越来越多的人所推崇。豆浆好喝,但一定要煮熟,豆浆中含有胰蛋白酶等抗营养因子,需经加热至100℃以后才能被破坏,在加热不彻底时会使人出现恶心、呕吐、腹泻等症状。有些人把豆浆加热至80-90℃,看到泡沫上涌就误以为已经煮沸,其实这是豆浆的有机物质受热膨胀形成气泡造成的上冒现象,并非沸腾,
Soybean protein content of up to 35% -40%, 1 kg of soy protein equivalent to 2 kg of lean meat or 3 kg of egg or 12 kg of milk protein content. Particularly beneficial is that soy is cholesterol-free and extremely beneficial to the brain.
