Yes. Milk is unhealthy. As babies, milk is very vital to our health but as we get older we stop producing enzymes to help digest milk. This is why a lot of people are lactose intolerant. To some degree almost every one is because our babies aren’t designed to consume milk as adults. Milk causes inflammation and produces mucus in the body. Although it is high in calcium and protein (which is good), it also causes distress throughout your body. Try drinking coconut or almond milk instead! Both of these have more calcium and vitamins then milk.
Conclusion: Our bodies weren’t designed to drink milk past our infant stage. It causes inflammation and many people are lactose intolerant.
