IS ALL MILK THE SAME?
Then there is the matter of where we get our milk. We have settled on the cow because of its docile nature, its size, and its abundant milk supply. Somehow this choice seems 'normal' and blessed by nature, our culture, and our customs. But is it natural? Is it wise to drink the milk of another species of mammal?
Consider for a moment, if it was possible, to drink the milk of a mammal other than a cow, let's say a rat. Or perhaps the milk of a dog would be more to your liking. Possibly some horse milk or cat milk. Do you get the idea? Well, I'm not serious about this, except to suggest that human milk is for humans calves, cats' milk is for kittens, and so forth. Clearly, this is the way nature intends it. Just use your own good judgement on this one.
Milk is not just milk.
The milk of every species of mammal is unique and specifically tailored to the requirements of that animal. For example, cows' milk is very much richer in protein than human milk. Three to four times as much. It has five to seven times the mineral content. However, it is markedly deficient in essential fatty acids when compared to human mothers' milk. Mothers' milk has six to ten times as much of the essential fatty acids, especially linoleic acid. (Incidentally, skimmed cow's milk has no linoleic acid). It simply is not designed for humans.
Food is not just food, and milk is not just milk. It is not only the proper amount of food but the proper qualitative composition that is critical for the very best in health and growth. Biochemists and physiologists -and rarely medical doctors - are gradually learning that foods contain the crucial elements that allow a particular species to develop its unique specializations.
Clearly, our specialization is for advanced neurological development and delicate neuromuscular control. We do not have much need of massive skeletal growth or huge muscle groups as does a calf. Think of the difference between the demands made on the human hand and the demands on a cow's hoof. Human new-borns specifically need critical material for their brains, spinal cord and nerves.
Can mother's milk increase intelligence? It seems that it can. In a remarkable study published in Lancet during 1992 (Vol. 339, p. 261-4), a group of British workers randomly placed premature infants into two groups. One group received a proper formula, the other group received human breast milk. Both fluids were given by stomach tube. These children were followed up for over 10 years. In intelligence testing, the human milk children averaged 10 IQ points higher! Well, why not? Why wouldn't the correct building blocks for the rapidly maturing and growing brain have a positive effect?
In the American Journal of Clinical Nutrition (1982) Ralph Holman described an infant who developed profound neurological disease while being nourished by intravenous fluids only. The fluids used contained only linoleic acid - just one of the essential fatty acids. When the other, alpha linoleic acid, was added to the intravenous fluids the neurological disorders cleared.
In the same journal five years later Bjerve, Mostad and Thoresen, working in Norway found exactly the same problem in adult patients on long term gastric tube feeding.
In 1930 Dr. G.O. Burr in Minnesota working with rats found that linoleic acid deficiencies created a deficiency syndrome. Why is this mentioned? In the early 1960s pediatricians found skin lesions in children fed formulas without the same linoleic acid. Remembering the research, the addition of the acid to the formula cured the problem. Essential fatty acids are just that and cows' milk is markedly deficient in these when compared to human milk.
WELL, AT LEAST COW'S MILK IS PURE
Or is it? Fifty years ago an average cow produced 2,000 pounds of milk per year. Today the top producers give 50,000 pounds! How was this accomplished? Drugs, antibiotics, hormones, forced feeding plans and specialized breeding; that's how.
The latest high-tech onslaught on the poor cow is bovine growth hormone or BGH. This genetically engineered drug is supposed to stimulate milk production but, according to Monsanto, the hormone's manufacturer, does not affect the milk or meat. There are three other manufacturers: Upjohn, Eli Lilly, and American Cyanamid Company. Obviously, there have been no long-term studies on the hormone's effect on the humans drinking the milk. Other countries have banned BGH because of safety concerns. One of the problems with adding molecules to a milk cows' body is that the molecules usually come out in the milk. I don't know how you feel, but I don't want to experiment with the ingestion of a growth hormone. A related problem is that it causes a marked increase (50 to 70 per cent) in mastitis. This, then, requires antibiotic therapy, and the residues of the antibiotics appear in the milk. It seems that the public is uneasy about this product and in one survey 43 per cent felt that growth hormone treated milk represented a health risk. A vice president for public policy at Monsanto was opposed to labelling for that reason, and because the labelling would create an 'artificial distinction'. The country is awash with milk as it is, we produce more milk than we can consume. Let's not create storage costs and further taxpayer burdens, because the law requires the USDA to buy any surplus of butter, cheese, or non-fat dry milk at a support price set by Congress! In fiscal 1991, the USDA spent $757 million on surplus butter, and one billion dollars a year on average for price supports during the 1980s (Consumer Reports, May 1992: 330-32).
Any lactating mammal excretes toxins through her milk. This includes antibiotics, pesticides, chemicals and hormones. Also, all cows' milk contains blood! The inspectors are simply asked to keep it under certain limits. You may be horrified to learn that the USDA allows milk to contain from one to one and a half million white blood cells per millilitre. (That's only 1/30 of an ounce). If you don't already know this, I'm sorry to tell you that another way to describe white cells where they don't belong would be to call them pus cells. To get to the point, is milk pure or is it a chemical, biological, and bacterial cocktail? Finally, will the Food and Drug Administration (FDA) protect you? The United States General Accounting Office (GAO) tells us that the FDA and the individual States are failing to protect the public from drug residues in milk. Authorities test for only 4 of the 82 drugs in dairy cows.
As you can imagine, the Milk Industry Foundation's spokesman claims it's perfectly safe. Jerome Kozak says, "I still think that milk is the safest product we have."
Other, perhaps less biased observers, have found the following: 38% of milk samples in 10 cities were contaminated with sulfa drugs or other antibiotics. (This from the Centre for Science in the Public Interest and The Wall Street Journal, Dec. 29, 1989).. A similar study in Washington, DC found a 20 percent contamination rate (Nutrition Action Healthletter, April 1990).
What's going on here? When the FDA tested milk, they found few problems. However, they used very lax standards. When they used the same criteria, the FDA data showed 51 percent of the milk samples showed drug traces.
Let's focus in on this because it's critical to our understanding of the apparent discrepancies. The FDA uses a disk-assay method that can detect only 2 of the 30 or so drugs found in milk. Also, the test detects only at the relatively high level. A more powerful test called the 'Charm II test' can detect drugs down to 5 parts per billion.
One nasty subject must be discussed. It seems that cows are forever getting infections around the udder that require ointments and antibiotics. An article from France tells us that when a cow receives penicillin, that penicillin appears in the milk for from 4 to 7 milkings. Another study from the University of of Nevada, Reno tells of cells in 'mastic milk', milk from cows with infected udders. An elaborate analysis of the cell fragments, employing cell cultures, flow cytometric analysis , and a great deal of high tech stuff. Do you know what the conclusion was? If the cow has mastitis, there is pus in the milk. Sorry, it's in the study, all concealed with language such as "macrophages containing many vacuoles and phagocytosed particles," etc.
