     Is dairy products healthy for us?                                                                               

      The industry tells us that we need dairy for protien and calcium and is said to be a energy rich food.

    What kind of protein is in milk?                                                                                

      Casein (from Latin caseus "cheese") is the most predominant phosphoprotein found in milk and cheese. When coagulated with rennet, casein is sometimes called paracasein. British terminology, on the other hand, uses the term caseinogen for the uncoagulated protein and casein for the coagulated protein. As it exists in milk, it is a salt of calcium.

      Casein is not coagulated by heat. It is precipitated by acids and by rennet enzymes, a proteolytic enzyme typically obtained from the stomachs of calves. The enzyme trypsin can hydrolyze off a phosphate-containing peptone.

      Casein consists of a fairly high number of proline peptides, which do not interact. There are also no disulphide bridges. As a result, it has relatively little secondary structure or tertiary structure. Because of this, it cannot denature. It is relatively hydrophobic, making it poorly soluble in water. It is found in milk as a suspension of particles called casein micelles which show some resemblance with surfactant-type micellae in a sense that the hydrophilic parts reside at the surface. The caseins in the micelles are held together by calcium ions and hydrophobic interactions.

      The isoelectric point of casein is 4.6. The purified protein is water insoluble. While it is also insoluble in neutral salt solutions, it is readily dispersible in dilute alkalis and in salt solutions such as sodium oxalate and sodium acetate.

    NOTE: In other words Casein is species specific. Casein is very compact and needs a special enzime to brake it up for digestion. Cows have this enzime called "rennet." Cows produce this rennet on the outter lining of the stomach.

    Lets compare the protein in milk in different species

      "Of all mammals, human milk has the lowest protein content and the lowest ratio of casein to whey."

        Proceedings of the Society for Experimental Biology and Medicine 1990: 193; 143

    NOTE: If more protein is good for us according to this chart we should be drinking rats milk.

      Question? Is a cow more concernd in rapid brain growth or muscle mass? Well, according to the chart cow's want muscle mass. The cow produces more protein and grows in weight in less time.

      Question? Is a human more concernd in rapid brain growth or muscle mass? Again according to the chart brain development. A human produces less protein and low casein. Mothers breast milk is perfict for brain development.

      Question? Is the brain made of protein or fatty tissues? Its made up of fat molicules. Studies have shown that kids that drink milk products have a lesser IQ than a kid that drinks breast milk. So why does the schools serve milk!

     What do the Pediatricians think?                                                                                

      "We should strive to use foods... that meet the nutrient needs of the older infant..., yet avoid toxicity. Cow milk simply does not meet this standard of quality."

        Journal of Pediatrics Gastroenterology and Nutrition 1993; 16 (1):2

      "Babies who are fed whole cow's milk during the second six months of life may experience a 30% increase in intestinal blood loss and a significant loss of iron in their stools."

        Pediatrics 1992; 89 (6): 1105-1109

           Question? Why do the infant bleed from milk? Again, it's from the protein. It's very hard to digest and is very                     irritating to the gut.

    NOTE: As you can see protein is just one of the problems in milk. The best solution is Mothers Milk, yes it has casein but it is in low quantity and the breast of the mother produces the right amount of enzymes for the baby to digest it.

     What about adults that drink milk?                                                                            

      "Adults who consume large quantities of milk, who have high lactase activity, suffer repeated small galactose challenges, accumulation of galactitol in the lens, and a greater likehood of developing senile cataracts."

        Postgraduate Medicine 1994; 95 (1):115

     Whats wrong with dairy products?                                                                            

    According to the Physicians Committee for  Responsible Medicine Washington, DC

    1: Fat and Cholesterol:

      Dairy products contribute cholesterol and fat to one's diet, Comparing the cardiovascular status of ovo-lacto-vegetarians and vegans has proven that while both are healthier than meat-eaters, vegans have better cardiovascular status that vegetarians who consume dairy products.

        JAMA 1983;234 (10):1337; Am J Clin Nutr 1989;50:280-87.

      Milk fat has been identified as a (cholesterol- elevating) fat because it contains cholesterol and is primarily saturated.

        Journal of Dairy Science 1991;74(11): 4002-4012

    2: Iron Deficiency:

      Insulin-dependent diabetes (Type I or childhood-onset) is linked to dairy products

        Am J Clin Nutr 1990;51:489-91

    3: Ovarian Cancer:

      A Harvard study found that when dairy product consumption exceeds the enzymes' capacity to break down galactose, there is a high build-up of galactose in the blood, which may affect a woman's ovaries

        Lancet 1989;2:66-71

    4: Diabetes

      Cow's milk linked to diabetes supported: LONDON (Reuter)--

        New evidence published Friday adds weight to a controversial theory that feeding cows' milk to babies may cause them to develop diabetes in later life, the Lancet medical journal said... (CNN June 1999)

      "Drinking cow's milk may weaken immune function in children and lead to problems with recurring infections.

        Nature 1978; 272 (5654): 632

      "A young age at introduction of dairy products and high milk consumption during childhood may increase the child's risk of developing juvenile diabetes.

        Diabetologia 1994; 37 (4): 381-387

     Why does milk cause diabetes?                                                                                 

    Diabetes is linked back to casein. Casein is very poorly digested. Which means it is broken into little bitty chunks and some of those pieces land up in your blood streem. At this point your bodys defense system picks up an abnormal protein. It so happens that the casein in cow's milk has the same amino-acid sequence in the molecule as the Beta cells to the pancreas in humans. Now your body is developing anti-bodies to destroy the abnormal protein and in the process destroying the Beta-cells in the pancreas , causing the pancreas to fail and as a result you get diabetes type one.

      Quote:"Early cow milk exposure may increase juvenile diabetes risk by about 1.5 times. "

        Diabetes Care 1994; 17 (1):13

    5) Cataracts:

      Cataracts are also linked to dairy products. The galactose also appears to damage the lens of the eye, leading to cataracts.

        Digestive Disease and Science 1982;27:257-64

    6) Lactose Intolerance:

    7) Food Allergies:

      Milk is one of the most common food allergies.

    8) Toxins:

      Like other products from animals, breast secretions contain frequent contaminants, from pesticides to drugs. About a third of all milk products are contaminated with antibiotics traces.

     How is Lactose broken down?                                                                                  

    Remember what Postgraduate Medicine said about Galactose:

      "Adults who consume large quantities of milk, who have high lactase activity, suffer repeated small galactose challenges, accumulation of galactitol in the lens, and a greater likehood of developing senile cataracts."

       

    9) Osteoporosis:

      Kolata G. How important is dietary calcium in preventing osteoporosis?

        Science 1986;233:519-20.

    10) Colic:

      One out of every five babies suffer from colic. Pediatricians learned long ago that cow's milk was often the reason. We now know that breast-feeding mothers can have colicky babies if the mothers are consuming cow's milk.

        PEDIATRICS 1991;87(4):439-444

     Is animal protein good for us?                                                                                  

    Lets find out:

      Osteoporosis is caused by a number of things, one of the most important thing being too much dietary protein!

        American Journal of Clinical Nutrition 1974; 27 (9): 916-925. Journal of Nutrition 1981; 111 (3) 545-552, 553-562. Science 1986; 233 (4763): 519-520

      A high ratio of dietary animal to vegetable protein increases the rate of bone loss and the risk of fracture in postmenopausal women.

        Selmeyer et al. 2001. AJCN 73 (1):118-122

      "Women in the highest quintile of ratio of animal to vegetable protein intake (>3.17) had nearly 4 - fold greater risk of frature compared with women with low ratios, independent of other risk factors, including age, calcium intake, weight, estrogen use, smoking status, alcohol use and total protein intake."

        LEUKEMIA

         

      Bovine leukemia virus (BLV) antibodies were present in 59% of newborn calves tested.

        Canadian Journal of Comparative Medicin 1979; 43 (2): 173-179

      Human T-cells leukemia virus can be transmitted from humans to animals. Such results suggest that a milk-borne infection being transmitted from a mother to her baby is very plausible. wheather it can pass from a cow to a human is being studied.

        Japanese Journal. of Cancer Research 1985: 76 (6): 481-487

      Iowa (a dairy state) has higher rates than the national average for human leukemias.

        American Journal of Epidemiology 1980; 112 (1): 80-92

      Pennsylvania veterinarians have been able to grow BLV in human cell in the laboratory. A 1980 study shows an increase in human leukemia in areas with high levels of bovine leukemia.

        Science 1981; 213 (4511: 1014-1016

      Cows infected with BLV had "significantly greater milk production" than their non-BLV infected herdmates, which could mean that more BLV-tainted milk is being produced than previously estimated.

        Proceedings of the National Academy of Science of USA 1989; 86(3): 993-996

    NOTE: Which cow do you think the farmers going to choose? The cow that produces the most milk.

      These data confirms the presence of BLV in milk and identify the potential for lactogenic (milk) transmission of the virus.

        American Journal of Veterinary Research 1995:36 (4): 445-449

        OTHER DISEASES

         

      Many diseases such as tuberculosis, brucellosis, diphtheria, scarlet fever, Q-fever, and gastroenteritis are transmissable by milk products.

        Journal of Dairy Science 1988; 71: 2809-2816

      Milk is an excellent vehicle of infection because its fat content protects pathogens from gastric acid, and, being fluid, it has a relatively short gastric transit time.

        Journal of the American Medical Association 1984; 252: 2048-2052

    NOTE: Now do you think milk or animal protein is good for you? still not convinced, because its pasteurised

      Listeria organisms excreted in cow's milk escaped pasteurisation, grew well at refrigeration tempertures, and were ingested (by consumers).

        New England Journal of Medicine 1985; 312 (7): 439

      These results support the hypothesis that human listeriosis can be a foodborne disease and raised questions about the ability of pasteurization to eradicate a large inoculum of listeria from contaminated raw milk.

        New England Journal of Medicine 1985; 312 (7): 404

                  High Infant Death Rates from Cow's Milk

               

      Improved medical treatments have changed this picture and currently the death rates are similar for breast and cow's milk formula fed infants except in lower socioeconomic groups and unsanitary conditions.

        Nelson Textbook of Pediatrics -14th Edition, 1992 p.116-117

      Even in our era of antibiotics in the USA, infants fed formula or cow's milk are 80% more likely to develop diarrhea and 70% more likely to develop ear infections when compared to breast fed infants.

        Scariati. PD et al Pediatrics 1997 June;99 (6):e5.
