I will be arguing that consuming dairy products is bad for your health. Con will be arguing that either dairy is entirely good for your health or that its benefits outweigh its health risk.

Round 1: Acceptance

Round 2: Opening Arguements

Round 3: Rebuttals/ Defence of Arguements

Thanks for accepting the debate. I look forward to a good response! I will list the problems with dairy below in no particular order.

Lactose Intolerance

Dairy is comprised primarily of fats, carbohydrates, proteins, and water. One of these primary carbohydrates is lactose. As infants, mammals can process the lactose using an enzyme secreted from their intestinal villi called lactase. This breaks the lactose down into two simple sugars: glucose and galactose.


Most people in the world (approx. 65%) have a drastically reduced ability to digest lactose after infancy, and increasingly so as the get older, resulting in the condition known as lactose intolerance. Mammals normally have a decrease in the gene expression which results in lactase production after infancy, as this enzyme is no longer required to digest mother's milk http://www.google.com...). Some people groups, such as those of European decent, have inherited a change in a regulatory element which regulates this gene expression, allowing for sustained production of lactase in their small intestine (http://ghr.nlm.nih.gov...). For much of the world, lactose will cause gastrointestinal problems (http://www.medbio.info...). For this reason alone, dairy is bad for the health of at least 65% of the world.



Cardiovascular Disease


Saturated fat is well known to be correlated with cardiovascular diseases (http://www.plosmedicine.org...). Dairy products are typically rife with saturated fat which raise the level of LDL (bad) cholesterol in your blood resulting in an increased risk for cardiovascular disease (http://www.heart.org...).



Cancer


Dairy consumption is strongly correlated with prostate cancer. While several mechanisms are possible, the correlation remains clear (http://www.pcrm.org...).


"Consumption of dairy products has also been linked to higher risk for various cancers, especially to cancers of the reproductive system. Most significantly, dairy product consumption has been linked to increased risk for prostate and breast cancers.



The danger of dairy product consumption as it relates to prostate and breast cancers is most likely related to increases in insulin-like growth factor (IGF-1), which is found in cow’s milk. Consumption of milk and dairy products on a regular basis has been shown to increase circulating levels of IGF-1.Perhaps the most convincing association between IGF-1 levels and cancer risk is seen in studies of prostate cancer. Case-control studies in diverse populations have shown a strong and consistent association between serum IGF-1 concentrations and prostate cancer risk. One study showed that men with the highest levels of IGF-1 had more than four times the risk of prostate cancer, compared with those who had the lowest levels. In the Physicians Health Study, tracking 21,660 participants for 28 years, researchers found an increased risk of prostate cancer for those who consumed ≥2.5 servings of dairy products per day as compared with those who consumed ≤0.5 servings a day. This study, which is supported by other findings,also shows that prostate cancer risk was elevated with increased consumption of low-fat milk, suggesting that too much dairy calcium, and not just the fat associated with dairy products, could be a potential threat to prostate health.



In addition to increased levels of IGF-1, estrogen metabolites are considered risk factors for cancers of the reproductive system, including cancers of the breasts, ovaries, and prostate. These metabolites can affect cellular proliferation such that cells grow rapidly and aberrantly, which can lead to cancer growth. Consumption of milk and dairy products contributes to the majority (60-70 percent) of estrogen intake in the human diet.



In a large study including 1,893 women from the Life After Cancer Epidemiology Study who had been diagnosed with early-stage invasive breast cancer, higher amounts of high-fat dairy product consumption were associated with higher mortality rates. As little as 0.5 servings a day increased risk significantly. This is probably due to the fact that estrogenic hormones reside primarily in fat, making the concern most pronounced for consumption of high-fat dairy products.



The consumption of dairy products may also contribute to development of ovarian cancer. The relation between dairy products and ovarian cancer may be caused by the breakdown of the milk sugar lactose into galactose, a sugar which may be toxic to ovarian cells. In a study conducted in Sweden, consumption of lactose and dairy products was positively linked to ovarian cancer. A similar study, the Iowa Women’s Health Study, found that women who consumed more than one glass of milk per day had a 73 percent greater chance of developing ovarian cancer than women who drank less than one glass per day" (http://www.pcrm.org...).





While this surely is not an exhaustive list of potential healthhazards faced by those who consume dairy, what I have included so far should be adequate for this debate's discussion.

Since my opponent forfeited, I'll try to give two possible arguments for the health benefits of dairy and rebut them.

Dairy is High in Calcium

". . .animal protein, including that from dairy products, may leach more calcium from the bones than is ingested, said Campbell, professor of nutritional biochemistry at Cornell and director of the Cornell-China-Oxford Project, the most comprehensive project on diet and disease ever conducted. 'This phenomenon could explain why Americans, who ingest much higher levels of calcium, have much higher rates of osteoporosis and hip fractures compared with many Chinese and other Asians who consume few dairy products and ingest low amounts of calcium,' Campbell said. Hip fractures in the United States, for example, are approximately five times more frequent than in China. . .increased levels of animal-based proteins, including protein from dairy products, 'almost certainly contribute to a significant loss of bone calcium while vegetable-based diets clearly protect against bone loss,' Campbell reported. This view is consistent with evidence comparing bone fracture rates among different countries, which shows that countries having the highest calcium intakes also have the highest fracture rates. It is also consistent with other studies on nutritionally rich 'Western' diets and 'Western' diseases showing that low-calcium, vegetarian diets are associated with increased bone density; that casein, milk's principal protein, is a well-established contributor to high blood cholesterol in the Western world; and that casein significantly enhances the development of tumor growth in experimental animals" (http://www.news.cornell.edu...).

Not only is the calcium component of dairy undermined by its casein component, which causes a loss of calcium from the bones, especially over long term consumption, but the risk factors associated with dairy, such as high blood cholesterol, far outweigh the benefits (https://www.drmcdougall.com...). There are plenty of safe, healthy sources of calcium in the plant kingdom: broccoli, kale, spinach, bok choy, soybeans, okra, watercress, and the list goes on.

Dairy is High in Vitamin D

Since I have already pointed out a few risk factors with dairy consumption, it should be obvious that one vitamin component does not outweigh the health risks associated with dairy. Almond and soy milk tend to be fortified with both calcium and vitamin D; they're a great alternative to dairy. Certain mushrooms such as portabella and maitake have more than five times as much vitamin D than a cup of cow's milk. Juices and cereals also tend to be fortified with vitamin D. It should be pointed out that vitamin D is produced naturally in the skin when exposed to sunlight and is a much more efficient source as 15-30 minutes of exposure to the arms and legs can give you more than six times as much vitamin D than an 8oz glass of milk (http://www.sunshinevitamin.org...). You would have to drink six glasses of milk, or 48 ounces, to get the daily recommended amount of vitamin D as proper sun exposure would give you (approx. 600IU)! And consider that 4,000IU is considered a safe upper-limit for adults (http://ods.od.nih.gov...).

Milk is definitely not a healthy source of calcium and vitamin D. Here is a letter by Dr. Robert M. Kradjian warning people about the health risks associated with dairy that the prospective reader may be interested in (http://www.notmilk.com...).

I'll be debating that the benefits of dairy overweigh the negatives :)
