Should we be drinking cow’s milk
Like all mammals, we drink breast milk when we’re born, It’s advised that human babies drink breast milk for up to six months to provide them with essential nutrients and help build their immune system. During these months our body produces an enzyme called lactase. Lactase helps to break down lactose, a sugar abundantly found in milk.
As we grow older, we start to produce less and less lactase. Why? Because we no longer need breast milk to survive because we’re now strong enough to get our nutrients from other foods, such as vegetables, fruit and meat. This is why you may start having issues digesting milk even later in life. Your body can gradually lose the ability to break down lactose properly. You can develop lactose intolerance or lactose maldigestion at any stage in your life you don’t have to be born with it.
Cows (and other mammals) are much like us. When calves are born, they suckle for seven to ten months. After this nursing period they eat grass to sustain them, and stop drinking milk altogether. Naturally, we should be doing the same. But we seem convinced that, after weaning, we need to continue drinking the milk of another animal to stay healthy. It seems a bit odd to me, and to many leading nutritionists it is becoming a clear danger area for health.
But Isn’t cows’ milk full of nutrients? Yes. It contains fat, sugar, protein and many important vitamins and minerals. However, most of the milk we drink is pasteurized, which means it’s heat-treated to kill possibly harmful bacteria. This process also kills a lot of the valuable vitamins, enzymes and other beneficial bacteria present in raw milk. We then often take out most of the fat to make skimmed milk, which removes many fat-soluble vitamins such as vitamin D.
