Answers to Questions About Milk

After a review of 56 articles was published in the Journal Pediatrics (the voice of the American Academy of Pediatrics-See below) in March 2005, documenting that milk does not strengthen bones, stunned reporters in Salt Lake City took to the streets to interview people. Just about all the mothers with a mic in their face stated they didn't care and they would continue to give milk to their children. In my opinion, this signals that no amount of evidence will any time soon undo the perception that "milk does a body good." Nonetheless, here are some answers to posted responses and more references. But, the best is for you do do your own research. Don't take my word or anybody else's as the final arbiter.

Are there no nutritional benefits to milk?

There are many nutritional benefits to milk; it has many amino acids, sugars, vitamins and minerals. In fact, the most perfect food is milk, as long as it is our own mother's. The problem is the downside of milk. So, the cost-benefit analysis will depend on your own opinion and how much you love the taste.... and sugar. Milk is much like processed red meat. These foods are very nutritious, but, the incidence of health problems to both is well documented. In a pinch (famine, etc) we do well to eat both. But, as a daily food they are problematic.

Is the calcium or some other component of milk the cause of increased cancer risk?

No, it's the growth hormones, antibiotics and pesticides given to cows to increase yield and profits. In addition, milk from cows or any other non human species has insulin from those foreign species, which increases not only the risk of diabetes in humans, but also the risk of cancer, since insulin acts like growth hormone. The calcium in milk is the reason why the industry claims that milk strengthens bones. But, its acidity and inflammatory effects on the gut curtail the absorption of minerals, so the net result is a much lower rate of absorption of calcium, not enough to significantly strengthen bones.

Are all forms of milk equally bad for you (whole, 2%, skim)?

No. The more processed the milk is, the worse it is for us. Cottage cheese seems to be the worst. Taking out fat out of milk does help those who have cholesterol problems; however, many of those people need to also eliminate excessive sugar, which is a concern in milk, too (lactose.) I believe "sugarholics" are the ones who find it nearly impossible to give up milk, ice cream and cheese.

"Would soda be a preferred beverage to milk or is water the only acceptable beverage for a healthy diet?"

Soda is just as bad for different reason, but equally addicting, in my opinion. It is the millions of dollars in advertisement by the food industry that creates the unfortunate impression that beverages are limited to soda and milk. After discouraging processed fruit juices prepared with High Fructose Corn Syrup, I encourage my patients to drink pure, organic, refrigerated carrot juice, in addition to green tea, and Pom wonderful. Any fruit and veggies juice will do. If you have weight or metabolic problems, try to get used to diluting these juices with water. After losing the addicting taste of excessive sugar, people find that q combination of 1/3 juice and 2/3 water is an excellent treat and very nutritious. Isn't it amazing that our society feels that water is not good enough?

Even though half of children who develop milk allergy by 7 months of age develop tolerance by 2 years of age, those who are IgE positive tend to remain allergic longer. These children, by the time they turn 8.6 years old, have more asthma, rhinoconjunctivitis, atopic eczema, urticaria, and more allergies in general. This study included 6,209 children, 118 of which had their allergy to milk confirmed by an elimination challenge (J. Allergy and Clinical Immunology 2005;116:869.)

* 58 studies reviewed. Most of them found no relationship between dietary calcium intake, and measurement of bone health.

* Dairy consumption is among highest in the USA, yet, osteoporosis and fracture rates are also high.

* Animal protein, including milk, is associated with urinary calcium losses.

* Doubling protein intake in creases loss of calcium by %50.

* Physical activity in 12-18 year-olds strengthens bones more than calcium intake.

* “We found no evidence to support the notion that milk is a preferred source of calcium.

* The NIH does not say that milk is the preferred source of calcium. Only the industry interpreted it so.

* “Calcium in dairy products is not as well absorbed as that in many dark green leafy vegetables... Dairy products contain protein and sodium (the latter competeswith calcium), and some dairy products, especially processed cheeses, clearly increase the urinary excretion of calcium as a result of the increase sodium, sulphur containing amino acids, and phosphorus content. Although dairy products tend to contain more calcium I absolute amounts than calcium-rich plant foods, when absorption fraction is taken into account, the amount of plant food needed to get the same amount of absorbable calcium is modest. For example, one cup of cooked kale or turnip greens, 2 packets of instant oats, two thirds cup of tofu, or 1 2/3 cups of broccoli provide the same amount as 1 cup of milk, as would 1 cup of fortified orange juice, soy milk, or basic 4 cereal.”
