Why are so many people in the world unable to digest lactose?
In: Biology
So gran and poppa came from the old country. In the old country they used cows for many things, yes yes uncle explitive existed, but thats VERY not ok. One of those things was milk, you like mac and cheese right? Milk comes from cows and we use that to make dairy products. Because we have been eating cow juice for a long time our bodies became friends and thats why we arent lactose intolerant. No your friends who can’t eat dairy are not goblins from middle earth. Their gran and poppa just didn’t cheese when they were kids. What? Sure I think the popsicle tree should exist too. Remember to brush your back teeth. Where did your brother go!!?
Adult version: Cattle were domesticated draft animals in certain areas. Their milk was abundant in fat and protein, which are vital nutrients. The areas that had cattle used the cattle juice, it made them poo. After many years they got a fun happy friend in their tummy and didn’t poo anymore. The areas that didn’t have cattle did not consume cow juice and didn’t get the happy friend.
