Not all type of stomach discomfort after meal are due to food poisoning. Have you ever suffer diarrhoea after enjoying foods with added cream? Do you ever wonder, why....
Milk contains lactose, which requires the help of lactase(an enzyme) to break it down into simple units for absorption. However, not everyone has the ability to produce the enzyme-lactase.
Drinking milk is a behavior that only became common in humans at a later stage of evolution. Therefore, the genes for lactase production capacity are unevenly distributed among the world population. Most people (especially Asians) have a rapid decline in lactase production capacity after infancy. Therefore, adult with lower ability to produce lactase, may suffer from stomach discomfort after consume diary products. Without lactase, lactose cannot be broken down into glucose and galactose. Undigested lactose will enter the large intestine and be fermented by bacteria resides in the large intestine. The fermentation process will release gas and generates acid. Gas induces bloating while acid irritates the intestines, causing cramps and diarrhoea (see Figure 5).
Fibre optimal contains lactase that helps break down lactose. It reduces the risk of bloating, cramps and diarrhoea.
用膳以后肚子痛,一定是食物中毒吗?不全是哦.你曾因食用添加了奶油的食物而腹泻吗?对一些人来说,在烹饪过程中加入牛奶可能导致膳后肚子痛.这是为什么呢?
牛奶中含有乳糖,需要乳糖酶的帮助,把它分解成简单的单位,然后吸收.然而,并不是每个人都有生产乳糖的能力.
喝牛奶是一种行为,人类在进化较晚的时期,喝牛奶才变得普遍.因此,乳糖酶生产能力的基因,在世界人口中分布不均。大多数的人(尤其是亚洲人),在婴儿期后,乳糖酶生产能力会迅速下降.因此一些成年人,因为没有乳糖酶,食用含有乳糖的产品后,乳糖不能分解成葡萄糖和半乳糖.未消化的乳糖将会进入大肠,被大肠细菌发酵。发酵过程将释放气体和酸。气体会引起腹胀,酸会刺激肠道,引起痉挛和腹泻(参考图5)。
Fibre optimal包含乳糖酶有助于乳糖分解,减少一些成年人在食用含有乳糖的产品后会腹胀、痉挛和腹泻的风险.
