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. Milk also 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 than milk.
Conclusion: Our bodies weren’t designed to drink milk past our infant stage. It causes inflammation and many people are lactose intolerant.
