It’s hard to believe that milk, which enjoys an almost sacred status in Indian culture, can be harmful for us. The reason is that it’s not the food that Nature intended for us. Milk is the food that every mammal produces for its infant and each animal produces the perfect formula for her species. But animal milk is not suitable for human beings at all! If you put petrol in a car that runs on diesel you will have problems even if petrol is perfectly good fuel.
