We might ask ourselves sometimes "How do I know if I am lactose intolerant?" or "What makes me lactose intolerant?"
There are different levels of lactose intolerance but the same principle applies to all: Your body is unable to digest lactose (a type of sugar mainly found in milk and dairy products).
Dairy products, like milk, contain lactose, which needs to be absorbed and used by the body. In order to do that lactose must be broken down into:
Galactose & Glucose
By an enzyme called LACTASE found in the intestine. Galactose and Glucose are then easily absorbed in your body and then turned into energy.
People who are lactose intolerant do not produce enough lactase to break down lactose. As a result, it sits in the intestine and instead gets broken down by bacteria causing gas, bloating, stomach cramps and diarrhea.
