Personally, I like drinking milk very much. When I was a child, I didn't have lactose intolerance. But when I grow up, sometimes my stomach hurts after drinking milk, so I summed up two small methods to deal with lactose intolerance. The first is to drink yogurt. There are more probiotics in yogurt, which promotes digestion in itself. The intestinal tract has stronger absorption capacity of yogurt, and it can also achieve the effect of supplementing protein, so I won't have a stomachache when I drink yogurt.
The second is to switch to low lactose milk or desensitized milk. Now all major milk brands have realized the shortage of products in this market, so all kinds of low-lactose and low-fat milk have also been listed. Pay attention to the lactose content when choosing milk, and those who drink low-lactose will not have symptoms of stomach discomfort.
