Do we really need milk? (Part II)

After reading Do we really need milk? (Part I) and learning about some of the myths related to milk we now invite you to take a look at Part II.

Milk contains contaminants that range from pesticides to drugs.

Milk naturally contains hormones and growth factors produced within a cow’s body. In addition, synthetic hormones such as recombinant bovine growth hormone (rBGH) are commonly used in dairy cows to increase the production of milk.

Because treated cows are producing quantities of milk nature never intended, the end result can be mastitis, or inflammation of the mammary glands. Treatment of this condition requires the use of antibiotics, and antibiotic traces have occasionally been found in samples of milk and other dairy products.


Pesticides, polychlorinated biphenyls (PCBs), and dioxins are other examples of contaminants found in milk. These toxins do not readily leave the body and can eventually build to harmful levels that may affect the immune and reproductive systems. The central nervous system can also be affected. Moreover, PCBs and dioxins have also been linked to cancer.

Dairy is one of the most commonly reported food allergies [Source: Rona, Nowak-Wegrzyn]. Even when not seen as a specific allergy, milk is frequently not tolerated by the gastrointestinal tract [Source: Nowak-Wegrzyn]. This is a problem that can extend beyond lactose intolerance.

For many, milk can cause bloating, constipation and even reflux. Clinically, milk may also be linked to increased eczema, worsening sinus problems, migraine headaches and joint pain [Source: Grant]. Milk is considered a mucus-producing food and is clinically thought to aggravate congestion. One Johns Hopkins physician, Dr. Frank Oski, has even written a book that shares his experiences of decreased rates of strep throat infection once children removed milk from their diets [Source: Oski]. Often, these conditions resolve or improve when milk is removed or eliminated from the diet.

As you know from the previous post Do we really need milk? (Part I), Calcium deficiency should not be something to worry about if  your diet is rich on vegetables, fruits and seeds, like chia or sesame.
