You have probably seen the advertisements with celebrities sporting milk mustaches. If so, you are familiar with the slogan, “Milk, it does a body good!” But, is milk really good for you? While proponents tout that drinking milk is the best and most efficient way to increase consumption of calcium, this claim is simply not true.
Many sources of calcium
It is true, however, that calcium should be consumed daily. It is essential to good health, particularly for your bones and teeth. Calcium is used for treatment and prevention of bone conditions such as osteoporosis (porous and weak bones due to low bone density), rickets (softening of bones in children) and osteomalacia (softening of bones with pain). Calcium can also protect major organs such as your heart. But, milk is not the only viable source of calcium. In fact, calcium can be found in a plethora of plant sources such as spinach, kale, broccoli, and cabbage. Robert Heaney, M.D., Professor of Medicine at the Osteoporosis Research Center at Creighton University School of Medicine reported, “The sheer quantity of calcium in dairy products certainly makes them attractive sources, but they have no monopoly on calcium. There`s no reason in the world why you couldn`t get an adequate intake from a vegetable source.”

Unfortunately, the typical American diet provides far less than the optimum level of calcium needed per day. Meaning, unless you consume a large amount of green vegetables on a daily basis, you will likely not be able to maintain the adequate supply of calcium that your body needs. Therefore, many individuals benefit from taking a calcium supplement.
You might be asking yourself, if calcium is so great, what’s wrong with drinking milk? The drawback is – when you drink cow’s milk, you usually get more than you bargained for. That’s because cow’s milk is loaded with a lot more than calcium. According to the Journal of Agricultural and Food Chemistry, the contents of each glass of milk can contain up to 20 different chemical agents including a variety of pharmaceutical drugs and growth promoters. Milk is often laden with hormones, antibiotics, pesticides, herbicides, bacteria, and environmental pollutants (organophosphates).
Milk then and now
In today’s world of “most meat for your money”, cows are raised on industrial farm factories called CAFOs (Concentrated Animal Feedlot Operations). On these CAFOs, cows are fed non-organic grains sprayed with pesticides and herbicides. They are also provided hormones to increase their growth rate. Specifically, dairy cows are supplied hormones called genetically-engineered recombinant bovine growth hormone (rBHG) to increase milk production. And sadly, over a dozen antimicrobials are approved for farm animal growth promotion in the US. These include antibiotics that are utilized for treating human disease, such as penicillin, tetracycline, and erythromycin. Truth be told, approximately 70% of the antibiotics produced by pharmaceutical companies today are actually used in animals. Thus, it’s best to leave the cow’s milk for baby cows.
