Have you ever experienced a reeeeaaally bad stomach ache after consuming a glass of milk thinking that “here’s to more rounds of toilet :(“ There are a few reasons as to why some people are unable to consume dairy milk. And one of the reasons is being (i) lactose intolerant.
Lactose intolerance (also known as lactase deficiency)is the inability to breakdown lactose which could normally be found in dairy products such as milk and cheese. Lactose is a sugar compound which is made out of glucose and galactose. It also makes up of around 3-8% of milk. Hence, they are unable to consume animal milk such as goat milk, cow’s milk, sheep’s milk etc.
People who are lactose intolerant have an insufficient amount of lactase in their small intestinesto digest the lactose. Therefore, the undigested lactose will move to the large intestine instead and is mixed with its own bacteria that would result in bloating, diarrhea and gas.
There are a few symptoms which indicates that you are suffering from lactose intolerance:
Another reason would be that person is(ii) allergic to dairy products or is a (iii) vegan.
People who are allergic to dairyshould stay awayfromlactose-free dairy products. While dairy-free products also means that it is lactose free, lactose-free products may not necessarily be dairy-free.
This is because lactose-free and non-dairy products contains milk proteinsuch as whey and casein which is unsuitable for those who are allergic to milk. Hence,dairy-free products are a better option for those who are allergic to milk as theydo not contain milk protein.
However, for vegans, it is advisable for them to consume dairy-free products instead since dairy is obtained from animals. Do be more alert about the labelings on the dairy products to ensure that you are buying the correct item.
