One Gallon of Milk + One Hour = Vomiting
There are basically four things in milk that are going to do you in as you attempt to drink a whole gallon in one hour.
1) The lactose: The problem with lactose is that your body can only process so much at a time. You need to have the enzyme lactase to deal with lactose. When you drink a full gallon of milk in an hour you burn through your available lactase and become lactose intolerant thus you throw up.
2) Calcium: The problem with calcium is that milk contains a lot of it around 300 mg per 8-ounce glass. A Tums chewable tablet for upset stomach contains about 200 mg of available calcium. So in chugging down a gallon of milk, it is like downing 25 Tums tablets at once. That obviously cannot be good for you. The acid balance gets messed up in your stomach and here comes the milk.
3) The casein: It also reacts with the acid in your stomach which turns to stringy curds, which is another reason to hurl.
4) PH levels: Drinking a gallon of milk will introduce large quantities of fat and protein. This will cause the normally low pH levels to rise and once again you induce vomiting.
But if you want to take the challenge to drink a gallon of milk in an hour go ahead but I’ll sit this one out, thanks.
