Cows milk is nature’s perfect food for a baby cow just as human breast milk is nature’s perfect food for a human baby. Humans are the only species that drinks the milk of another species and continues to drink milk past infancy. And most adults in other parts of the world to do not consume much dairy. Continents with the lowest dairy consumption, ie. Asia and Africa, have the lowest rates of osteoporosis. And milk has never been shown to reduce fracture risk.
Many cows are given growth hormones and these get passed on to us when we consume their products (milk, cheese, yogurt, ice cream, and meat). You don’t have to be a genius to realize hat this cannot be healthy to consume. All I have to do is take a look at all the young girls who are reaching puberty at younger and younger ages, fully developed with their periods at ages where they shouldn't even have to think about that time of the month.
In order to keep milk production of milking cows at a high level, the cows are kept pregnant all the time. This is good for milk production and for keeping the cost of milk down, but bad for our health. A pregnant cow naturally has very high levels of estrogen, progestins, androgens, and other hormones, which get passed through to their milk. It is this high concentration of hormones that is troublesome.
If you do choose to drink milk, it really is worth it to pay the additional price for organic. At least with organic milk you can be assured that there are no added growth hormones and the cows are supposedly raised grass fed in open pastures as opposed to grain and protein fed in pens.
If you absolutely have to drink some milk, I suggest lowering your intake. I know it's really really difficult. I love ice cream, cheese and yogurt VERY MUCH and have a tendency to over do it sometimes. If I have yogurt as a snack during the day, then I will pass on the cheese in the evening during dinner. I don't know if I could ever not have dairy completely, but have reduced my intake by fifty percent during the last year. I also buy organic as much as possible.
Now if you want to really take a leap of faith I would suggest removing all dairy products from your diet for 30 days. On day 31 have a big glass of milk, a grilled cheese sandwich, a big bowl of ice cream, etc. Just load on the dairy and see how you feel. Many people who completely remove dairy for 30 days report a variety of symptoms strangely disappearing. Coughs, stomach distress, migraines, so it’s worth a try if you have health concerns that you can’t seem to shake.
