Con to the question "Is Drinking Milk Healthy for Humans?"
"The dairy industry has done a great job of convincing us that milk and dairy products are necessary for good health and it uses its formidable power to relentlessly reinforce this message. Starting in kindergarten, young children are told that milk builds strong bones and teeth. Biology students learn that milk and dairy are the default sources of calcium and vitamin D - usually with no mention of healthier and more environmentally friendly ways to get these vital nutrients. Later, you might hear how low-fat milk can help you lose weight or even prevent osteoporosis - despite all evidence pointing to the exact opposite...
If this sounds strange to you, it's because few people are willing to tell the truth about dairy. Think about it, there's nothing natural about consuming cow's milk. All mammals produce their own milk to nourish their young, but nature never intended human babies to consume milk that is supposed to be for young cows...
Most dairy cattle are injected with a cocktail of hormones to artificially increase milk production. One of these, IGF 1 (insulin-like growth factor 1), stimulates the rapid growth of calves (and humans) by boosting the division and multiplication of all cells - including abnormal ones. Perhaps not surprising that many studies have found a link between IGF 1 and various cancers.
I'm not saying everyone should eliminate all dairy products overnight, but these health factors, combined with the environmentally damaging nature of large-scale milk production, make it clear that cow's milk isn't the healthy food we were brought up to believe."
