Why Milk or not?

Except for animals under human influence and Western gulls who steal milk from lactating seals, humans are the only known species that drinks the breast milk of another species, and the only known species that continues to drink breast milk into adulthood.

Don’t We Need Milk?

Milk from a cow is as necessary as milk from a pig or a horse or a giraffe. Human breast milk is the perfect food for human babies, while cow’s milk is the perfect food for baby cows. Cow’s milk naturally contains the large amount of hormones and protein needed to turn a 80-pound calf into a 1,000 pound cow in one year. That amount of protein and hormones is not only unnecessary but unhealthy for humans. Because they occur naturally, these hormones are even found in organically produced milk.

The American Dietetic Association supports a dairy-free, vegan diet:

It is the position of the American Dietetic Association that appropriately planned vegetarian diets, including total vegetarian or vegan diets, are healthful, nutritionally adequate, and may provide health benefits in the prevention and treatment of certain diseases.
Besides containing saturated fats, cholesterol, hormones and too much protein, milk is also linked to testicular cancer, breast cancer, and prostate cancer.

Fat, Cholesterol and Protein

Many dairy products tend to be high in saturated fats and cholesterol, which have been linked to heart disease. The American Dietetic Association states:

Features of a vegetarian diet that may reduce risk of chronic disease include lower intakes of saturated fat and cholesterol and higher intakes of fruits, vegetables, whole grains, nuts, soy products, fiber, and phytochemicals.
Milk protein is also a concern, and the protein in milk has been linked coronary deaths and to hardened, narrowed arteries.

Hormones, and Cancer

In 2006, a researcher from the Harvard School of Public Health found a strong link between dairy consumption and hormone-dependent cancers – testes, breast, and prostate. Scientist/physician Ganmaa Davaasambuu believes that the naturally occurring hormones in a pregnant cow’s milk increase the risks for these types of cancer. Milk from cows contains “considerable amounts of female sex hormones,” accounting for 60-80% of estrogens consumed by humans. Although the research focused on dairy, Ganmaa’s findings implicated a variety of animal products, as well as dairy:

Butter, meat, eggs, milk, and cheese are implicated in higher rates of hormone-dependent cancers in general, she said. Breast cancer has been linked particularly to consumption of milk and cheese.
Ganmaa’s findings are not unique. According to dietician George Eisman, in the US, one in six men gets prostate cancer. Only one in 200,000 men gets prostate cancer in China, where dairy is not regularly consumed. Also according to Eisman, breast cancer is highest in the countries with the highest dairy consumption. A study in England found that even within England, the counties with the highest dairy consumption had the highest rates of breast cancer. Eisman states that consuming dairy is “the most abnormal, crazy thing that we do.”

Contaminants in Milk

Contaminants in milk are another serious concern. American milk is banned in the European Union because of added recombinant bovine growth hormone (rBGH). When administered to cows, rBGH causes the cows to produce up to 20% more milk, but also causes the cows to produce more Insulin-like Growth Factor 1 (IGF-1). According to the Organic Consumers Association, some of the rBGH given to cows ends up in the milk. The Cancer Prevention Coalition (CPC) states:

It is highly likely that IGF-1 promotes transformation of normal breast cells to breast cancers. In addition, IGF-1 maintains the malignancy of human breast cancer cells, including their invasiveness and ability to spread to distant organs.
RBGH also increases the risk of mastitis, which sometimes leads to pus, bacteria and blood getting into the milk. Federal law in the US allows up to 50 million pus cells per cup of milk.

If rBGH is so dangerous and is banned in the EU, why is it legal in the US? The CPC believes that, “Monsanto Co., the manufacturer of rBGH, has influenced U. S. product safety laws permitting the sale of unlabeled rBGH milk.”

Another contaminant found in cow’s milk is pesticide residues. Residues are fat soluble, which means they become concentrated in the milk and tissues of animals.

What About Calcium?

While cow’s milk is high in calcium, it is also high in protein. Excess protein in our diets causes calcium to leach out of our bones. Dr. Kerrie Saunders states, “North America has one of the highest consumptions of dairy products, and also the highest incidence of osteoporosis.“ To combat osteoporosis, Saunders recommends exercise and “beans and greens” for a source of calcium that is not excessively high in protein. Ganmaa also recommends getting calcium from green leafy vegetables.

Furthermore, calcium intake may be less important for bone health than we’ve been led to believe. A study by researchers from the Harvard School of Public Health published in 1997 found that increased consumption of milk and other calcium-rich foods by adult women did not reduce the risk of osteoporotic bone fractures. Calcium retention is also important for preventing osteoporosis. Sodium, smoking, caffeine and physical inactivity can all cause us to lose calcium.

Lactose Intolerance
Lactose intolerance is common among many populations, affecting approximately 95 percent of Asian Americans, 74 percent of Native Americans, 70 percent of African Americans, 53 percent of Mexican Americans, and 15 percent of Caucasians. Symptoms, which include gastrointestinal distress, diarrhea, and flatulence, occur because these individuals do not have the enzyme lactase that digests the milk sugar lactose. For those who can digest lactose, its breakdown products are two simple sugars: glucose and galactose. Nursing children have active enzymes that break down galactose. As we age, many of us lose much of this capacity. Babies and small children can be allergic to milk, and experience symptoms including ear infections, skin rashes, and digestive problems..

While animal rights advocates are vegan for ethical reasons, it’s important to know that cow’s milk is not necessary for human health and foregoing dairy or reducing intake appears to have a lot of health benefits.!

    I had an older share widget, dont know where that went:)

  3. oh and do let me know if there are certain things u want to write about.

    The scare and torture tactic doesnt seem to work to get people to read and make diet changes. so i am writing about nutrition and health effects now.:)
