Top 10 Pro & Con Arguments
Is drinking milk healthy for humans?






1. Doctor's Advice on Milk

"Milk is one-stop shopping for nutrition. It contains nearly all the basic nutrients that a growing child needs: fats, carbohydrates, proteins, vitamins and minerals (except iron). While it is true that most of the nutrients in milk can be gotten easily from other sources, such as vegetables, legumes, and seafood, milk puts them all together in a convenient package. Realistically, children eat or drink dairy products in greater amounts and more consistently than other foods. While whole milk is not the only way to get calcium in a child's diet, it's the most practical way."

Bill Sears, MD
Associate Clinical Professor of Pediatrics at the University of California Irvine

"There was a time when it [milk] was considered very desirable, but research has forced us to rethink this recommendation... Dairy products contribute to a surprising number of health problems. They can impair a child's ability to absorb iron and in very small children can even cause subtle blood loss from the digestive tract. Combined with the fact that milk has virtually no iron of its own, the result is an increased risk of iron deficiency."

2. Milk and Heart Disease

"The men with the greater consumption of milk experienced a reduction in the risk of ischaemic [inadequate blood flow] stroke and a possible reduction in ischaemic heart disease risk. Explanations of these results other than a beneficial effect of milk would seem to be unlikely. The present perception of milk as harmful, in increasing cardiovascular risk, should be challenged and every effort should be made to restore it to its rightful place in a healthy diet."

Peter Elwood, MD
Professor of Epidemiology at Cardiff University
"Milk Consumption, Stroke, and Heart Attack Risk: Evidence from the Caerphilly Cohort of Older Men,"
Journal of Epidemiology and Community Health
2005


"Several studies have been published showing a high positive correlation between milk consumption in different countries and rates of death a few years later from CHD [Coronary Heart Disease]. One investigation showed that countries which reduced milk consumption later had reduced rates of CHD death, while the only country studied which increased its milk consumption [Portugal] had an increased rate of CHD death."

3. Milk and Lactose Intolerance

"Individuals vary in their degree of lactose intolerance, but even children and teenagers with primary lactose intolerance can usually consume 8 to 12 ounces (1 to 1.5 cups) of milk without experiencing symptoms.

Although the degree of lactose intolerance varies, most people with lactose intolerance do not require a completely lactose free diet. Milk and milk products should not be completely eliminated because they provide key nutrients such as calcium, vitamins A and D, riboflavin, and phosphorus."

National Institute of Child Health and Human Development
"Lactose Intolerance: Information For Health Care Providers"
Jan. 2006


"Studies have suggested that some of the nutritional benefits of milk may be lost when a lactase-deficient [lactose intolerant] individual consumes milk. Not only does this person fail to receive the calories normally supplied by the undigested carbohydrates; resultant diarrhea may lead to loss of protein as well.

Two studies were conducted in groups of children with 'recurrent abdominal pain of childhood,' one study preformed in Boston and the other in San Francisco, came to a similar conclusion. The conclusion was that about one-third of such children had their symptoms on the basis of lactose intolerance. The simple solution was to remove all milk and milk-containing foods from the diet."

4. Milk and Cancer

"This is the first clinical trial to show that boosting vitamin D status can affect the overall risk for cancer - a proposition that has tremendous public health potential.

By choosing vitamin-D rich foods like milk and taking a supplement Americans can help improve their vitamin D levels and potentially impact their cancer risk."

Joan Lappe, PhD
Director of Clinical and Pediatric Studies at Creighton University
"Vitamin D and Calcium Supplementation Reduces Cancer Risk: Results of a Randomized Trial,"
American Journal of Clinical Nutrition June 2007


"One reason milk consumption may lead to cancer risk is insulin-like growth factor, IGF-1 (not to be confused with bovine growth hormone, rBGH). Milk contains IGF-1 for good reason: milk is designed for babies, and IGF-1 helps us grow. IGF-1 affects growth, as well as other functions, and is normally found in our blood. Higher levels of IGF-1, however, appear to stimulate cancer cells."

5. Milk and Bone Health

"Findings from ongoing studies indicate that four to five servings/day of calcium-rich foods such as milk and other dairy products are needed to optimize peak bone mass during adolescence. Osteoporosis is a pediatric disease with geriatric consequences. With low calcium intake levels during important bone growth periods, today's youth faces a serious public health problem in the future."

Connie M. Weaver, PhD

"Bone Health Hazards: The Make-It-Or-Break-It Teenage Years" (in "Calcium Summit II: Agenda for Action,"
on the National Dairy Council website
Jan. 2002


"There is much debate over whether long-term consumption of dairy products helps bones at all. A good deal of evidence suggests that it does not. Several studies of teenagers have found that their adult bone health is related to their physical activity level earlier in life, but not to the amount of milk or calcium they consumed. Milk consumption is apparently no help later in life either."

6. Milk and Weight Loss

"Mounting research indicates that consuming more calcium in the diet - particularly from calcium-rich dairy foods - can speed up weight loss and reduce body fat, particularly abdominal fat. Consuming dairy products appears to help prevent body weight and fat gain in children and adults, Caucasians and African-Americans, males and females. In addition, dairy foods have proven to be more effective than calcium alone in moderating body weight/fat gain and accelerating weight/fat loss...

The mix of essential nutrients in dairy foods, including calcium and protein, appears to speed up metabolism and improve the body's ability to burn fat, especially abdominal fat."

"Nearly half of American women say that they have heard that dairy foods help people lose weight. If only there were sufficient evidence to back up the claim...

There's no evidence to support the milk industry's claim that 'more than a dozen research studies now support the finding that drinking 24 ounces of milk every 24 hours will help people lose more weight than just reducing their caloric intake.' None of Zemel's [a leading advocate of the theory that milk consumption helps with weightloss] studies instructed people to drink 24 ounces of milk a day. And MilkPEP, the industry's non-profit Milk Processors Education Program couldn't point us to a single study in which people did."

7. Synthetic Hormones in Milk

"FDA [Food and Drug Administration] is concerned that the term 'rbST-free' [synthetic bovine growth hormone free] may imply a compositional difference between milk from treated and untreated cows rather than a difference in the way the milk is produced... Such unqualified statements may imply that milk from untreated cows is safer or of higher quality than milk from treated cows. Such an implication would be false and misleading.

There is currently no way to differentiate analytically between naturally occurring bST and recombinant bST in milk, nor are there any measurable compositional differences between milk from cows that receive supplemental bST and milk from cows that do not."

Food and Drug Administration
"Interim Guidance on the Voluntary Labeling of Milk and Milk Products From Cows That Have Not Been Treated With Recombinant Bovine Somatotropin,"
Feb. 14, 1994


"It is well known that rBGH [synthetic bovine growth hormone] increases levels of another growth hormone, IGF-1, which is identical in cows and humans. At elevated levels, IGF-1 is known to increase cancer rates in humans.

Most of the industrialized nations of the world, including Canada, Australia, New Zealand, Japan and all 25 nations of the European Union, have disallowed the use of rBGH, based primarily on human and animal health concerns. The Codex Alimentarius, the U.N.'s main food safety body, has concluded there is NO consensus that rBGH is safe for human consumption."

8. Flavored Milk in Schools

"Unflavored milk is lower in sugar than flavored milk. However, given the importance of calcium, vitamin D and other key ingredients in the diet of children and adolescents, flavored milks could be a nice alternative since the contribution of added sugars to the overall diet of young children is minimal."

American Academy of Pediatrics
"Clearing Up Confusion on Role of Dairy in Children's Diets"
AAP News
June 2000



"Flavored milks are not a particularly healthy beverage option for children or teens. As with unflavored cow's milk, flavored cow's milk is a significant source of fat, saturated fat, and cholesterol in children's diets. The naturally occurring sugar in cow's milk is lactose, a type of sugar that is not well-digested by many children after about age 4. Flavored milks also have sugar added, often to the point where, ounce for ounce, they contain the same amount of total sugar as soda."

9. Conventional Non-Organic Milk

"There is no difference between organic and regular milk. Both contain the same unique package of nutrients that makes dairy products an important part of a healthy diet. An 8-ounce serving of organic or regular milk offers the same amount of nine essential nutrients, including calcium, vitamin D and potassium...

Strict government standards ensure that regular milk is just as pure, safe, and nutritious as organic milk..."

"Organically reared cows, which eat high levels of fresh grass, clover pasture and grass cover silage, produced milk which is on average 50% higher in vitamin E (alpha tocopherol), 75% higher in beta carotene (which our bodies convert to vitamin A) and two to three times higher in the antioxidants lutein and zeaxanthine than non-organic milk... In addition, we found higher levels of omega 3 essential fatty acids."

10. Pasteurized vs. Raw Milk

"Although some people claim that 'raw' milk possesses positive nutritional and health-promoting attributes, these claims have not been scientifically substantiated. USDA, FDA, Centers for Disease Control [and Prevention] and many other scientific authorities recommend against consumption of 'raw' milk. 'Raw' milk can contain a variety of microorganisms that can be harmful and even fatal to people - including bacteria campylobacter, Escherichia, listeria, salmonella, yersinia and brucella. Pasteurization, however, destroys any harmful microorganisms and renders milk safe for everyone to consume."

Washington Dairy Products Commission

"What Is Milk?,"
havemilk.com Apr. 4, 2007


"While it is certainly possible to become sick from drinking contaminated raw milk, it is also possible to become sick from almost any food source. But it seems that raw milk has been unfairly singled out as a risk, when only a very small risk exists...

Raw milk is an outstanding source of nutrients including beneficial bacteria such as lactobacillus acidophilus, vitamins and enzymes, and it is, in my estimation, the finest source of calcium available...People who have been allergic to pasteurized milk for many years can typically tolerate and even thrive on raw milk."
