“Milks are such a good thing to drink, I wonder why Jason suffer from drinking it”. If you ever had this question, we will solve this for you before starting our topic of the day; the “Jason” here may have lactose intolerance.
What is lactose intolerance?
People with this find themselves unable to fully digest lactose, which is normally from dairy product.
What if they still want to eat dairy product?
Since the body cannot digest lactose like other people, undigested lactose will go into large intestine to interact with bacteria in large intestine. Then symptoms like bloating, diarrhea and gases will come.
Why people develop this?
Back when we are all baby, we can all digest milk, but the enzyme that digest lactose become turned off when we grow into adulthood. Mutation then happens on some human when they start to domesticate cows for milks and become able to digest lactose even if they are adult.
It is the science that enable we people to enjoy dairy products! We hope this article sparkles your mind for your good day!
