The Milk Myth or “It’s part of my culture.” Milk has something for everybody. There is one thing dairy products have more than any other food I can think of: contamination. John McDougall, MD Some extras you can get from milk... • • • • • • Digestion trouble • Low blood levels of: – Calcium Higher cholesterol – Manganese Allergies – Magnesium Lactose intolerance – Zinc Bacterial growth – Iron Bowel disorders – Copper Type I Diabetes factors: Early dietary exposure to cow’s milk Short duration of breast feeding High milk intake after age 9, or at diabetes onset Recent infection Attending day care before age 3 The enemy is us?! There is a 17-amino acid peptide chain commonly found in the insulin-producing beta cells of the pancreas. There is a 17-amino acid peptide chain commonly found in cow’s milk. Both are nearly identical. Children with IDDM had elevated serum concentrations of antibodies against bovine whey protein. Mice, milk, and me Diabetes does not occur in diabetes-prone rodents reared on a diet free of cow’s milk for the first two or three months of life, indicating that cow’s milk protein can trigger the disease. New England Journal of Medicine 1992 The Milk/Allergy Connection • • • • • • Constipation Eczema Dermatitis Vomiting Headaches Psychological problems • Retarded growth • Fatigue • Bed-wetting An estimated 50 million Americans experience intestinal discomfort after consuming dairy products. Symptoms include bloating, stomach pain, cramps, gas, diarrhea. Postgraduate Medicine 1994 Colic About 20% of babies suffer from colic, or abdominal cramping and gas. Milk proteins may be one of the leading causes of this digestive disorder.

Digestive Diseases and Sciences 1982 The Pharyngitis Connection Any time a patient of mine is found to have streptococcal pharyngitis or pyoderma, we can establish by history that he has ingested milk protein within five days...

The Protein Connection Osteoporosis is caused by a number of things, one of the most important things being too much dietary protein! American Journal of Clinical Nutrition 1974 Journal of Nutrition 1981 Science 1986 Causes of Osteoporosis • High protein diet - over 50 gm. protein/day gives negative calcium balance. American men and women both take more than 50. • • • • Tobacco use - 1% loss/year Coffee use (1 cup) - 1.4% loss/year Deficiency of zinc, fluoride, magnesium High phosphorus intake: Soft drinks Milk Red meats Yeast Processed meats Processed cheese Baking powder Instant soups #1 A Protein-rich diet Women average: 90-130 grams Men average: 110-180 grams Protein burdens the kidneys causing heavy calcium losses Less than 50 grams protein produces positive calcium balance More than 50 grams or protein produces a negative calcium balance Causes of Osteoporosis High Phosphorous Intake Soft drinks Red Meats Instant soups Processed meats Baking powder Processed cheese Milk Brewer’s Yeast Detergents Other Lifestyle Factors Birth control pills Aluminum antacids Thyroid supplement Smoking Alcohol Tetracycline Alum Steroids High fat diet High Intake of Low Intake of Sodium, Vitamin A, Vitamin D Zinc, Fluoride To Control Salt Intake... • • • • • • Avoid Canned vegetables Bakery goods Processed meats Use no: Dairy products Salt in preparing food Salt at the table Mother’s milk 350 mg/l Cow’s milk 1500 mg/l Result: A therapeutic low-salt diet (approximately 1 gram) Magnesium Functions • • • • Constituent of bones and teeth Reduces muscular sensitivity - tremors Enzyme cofactor Prevention of disease – – – – – Osteoporosis Hypertension Cancer High blood cholesterol Heart and artery disease Requirement: 300-500 mg. per day • Nuts, seeds • Grains oats corn barley wheat rice rye • Legumes - peanuts, peas, beans • Carob • Fresh vegetables - beets, greens, squash, green vegetables • Fruits How much calcium is really needed?

Low Absorption of Calcium From Milk • Only 25% of dairy calcium is absorbed by the body. • Human milk with less than half the calcium is better absorbed. • Kale, greens, or sesame seeds are better sources for the same reason It’s the Law! U.S Public Health Service regulation: “Milk, after pasteuration, should contain no more than 20,000 bacteria per millileter of milk and no more than 10 coliform bacteria per each milliliter.”
