Lots of people think they are lactose intolerant. And as it turns out, most of them are probably right because a vast majority of people over the age of two are legitimately lactose intolerant. Confused? we’ll walk you through it.
Lactose is a naturally occurring disaccharide (a fancy word for two sugars bonded together) made up of glucose and galactose.
Lactose needs to broken down by the enzyme lactase to be digested. When there isn’t enough lactase, a common syndrome known as “lactose intolerance,” bacteria in your gut try to ferment it, leading to some uncomfortable symptoms.
First off, how do you feel after drinking milk or eating a bowl of ice cream? Common symptoms include stomach ache, gas, diarrhea, a big, bloated belly, feeling uncomfortably full, abdominal cramps, nausea, vomiting, and in some, constipation.
Many people complain of discomfort after consuming milk products, and there’s a reason why. A vast majority of humans over the age of two are lactose-intolerant.
Yup, you read that right. It’s more unusual to be lactose-tolerant than lactose-intolerant.
Biologically, humans like all mammals are designed to consume milk from their mothers while they are young. Thus, they’re born with quite a bit of lactase, the enzyme that helps you digest it.
But as you get older, your body starts to produce less and less lactase, because, biologically, most mammals stop drinking milk and needing large amounts of lactose beyond infancy.
So once you pass the ripe age of two, 75% of people have way less lactose than you were born with because mother nature decided a long time ago you didn’t need it. Lactose intolerance is extremely common in Asian descent.
Lactose intolerance can cause diarrhea and serious stomach pain, so if you suffer from excessive runny stool, make sure you are hydrated and properly nourished, as diarrhea can make your body miss out on absorbing many of the things it needs.
That said, lactose intolerance is an intolerance, not an allergy, which is an important distinction. People with milk allergies can have life-threatening reactions to even trace amounts of dairy, and lactose-intolerance—while certainly uncomfortable—is not the same thing.
Most people who are lactose-intolerant can tolerate up to two servings of milk-products per day (even better if they’re spaced out) without too many issues, but everyone is different, and only you know your body best.
Just make sure that if you rely on dairy for calcium and vitamin D, you get these nutrients from other sources, like fortified non-dairy alternatives and cereals, or from certain fruits, vegetables, legumes, and tofu.
