Lactose Intolerance

Did you know that roughly 65-percent of people throughout the world are lactose intolerant to some degree? People may even become more lactose intolerant with age, especially if they are not eating dairy products that often. Lactose, a type of sugar, will then be difficult for the body to breakdown, and this can cause gas, bloating, indigestion, burping, diarrhea or constipation, nausea, cramping, and so on after consumption.


The reason lactose becomes more challenging for the body to digest is either a shortage of an enzyme called lactase, which is produced in the small intestine, or malabsorption of lactose, caused by undigested lactose getting taken into the colon. Those who are lactose intolerant should avoid dairy products that are not lactose-free. You can find lactose-free milks and cheeses in the grocery store, or you can switch to a non-dairy alternative.
