According to a study done by the Jaffe Food Allergy Institute, milk is one of the most commonly reported food allergy. For many, milk can cause bloating, constipation, migraines, joint pains, sinus problems and eczema. Milk is considered a mucus producing food and therefore is often linked to recurring ear infections or respiratory problems such as coughs, runny noses, etc. Pasteurized milk is perhaps one of the most nutritionally deficient beverages inappropriately labelled as a "perfect food." Pasteurization destroys enzymes, denatures fragile milk proteins, destroys vitamins C, B12 and B6, kills beneficial bacteria, promotes pathogens and is associated with allergies, increased tooth decay, colic in infants, growth problems in children, osteoporosis, arthritis, heart disease and cancer.
Milk affects hormone levels Milk and other dairy foods contain the hormone estrogen, which encourages tumour growth. Part of the problem is that cows in modern dairy farms are milked about 300 days per year. For much of that time, the cows are pregnant. The later in the pregnancy a cow is, the more hormones are present in the milk. Milk from a cow in the late stage of pregnancy contains up to 33 times as much of an estrogen compound, called estrone sulphate, than milk from a non-pregnant cow. Once in the body it is converted to estrone or estradiol (forms of estrogen).
According to a study undertaken by Ganmaa Davaasambuu, Ph.D., dairy accounts for 60 – 80 percent of estrogens consumed. This study found that a boy who drinks 300 ml of milk a day is calculated to take in 100 nanograms estrone sulphate. According to a Danish the daily production of estradiol in prepubertal boys is in the range of 40 to 10 nanograms. The amount of estrogen in milk does not only affect the hormone levels in boys but also girls. High amounts of estrogen can contribute to infertility, breast cancer and many other hormonal problems. Milk affects insulin levels Professor Loren Cordain, PhD, Department of Health and Exercise Science, Colorado State University, claims that cow’s milk causes a spike in insulin levels. He researched what happens to people’s bloodstream after drinking a glass of milk. He was amazed to find that a glass of milk had the same bad effect on insulin levels as eating a slice of white bread or a packet of M&Ms. Drinking that glass of milk sent insulin levels soaring. High insulin levels are associated with obesity, insulin resistance, diabetes, and cardiovascular disease. According to the Journal of the National Cancer Institute, high insulin levels raise the risk of breast cancer in postmenopausal women.
