Dairy products can cause health issues for individuals who have lactose intolance or a milk allgergy . Some dairy products such as blue cheese may become contaminated with the fungus aspergillus fumigatus during ripening, which can trigger asthma and other respiratory problems in susceptible individuals. Dairy products if consumed after the expiry date can cause serious heart problems.
Physicians and nutritional biochemist T,Colin Campbell, argue that high animal fat and protein diets, such as the standard American Diet, are detrimental to health, and that a low-fat vegan diet can both prevent and reverse degenerative diseases such as coronary artery disease and diabetes.A 2006 study by Barnard found that in people with type 2 diabetes, a low-fat vegan diet reduced weight, total cholesterol, and LDL cholesterol, and did so to a greater extent than the diet prescribed by the American Diabetes Association.Various scientists and physicians have noted that there may be a link between dairy consumption and some cancers such as breast and prostate cancer.
Cows produce milk for the same reason that humans do: to nourish their young. In order to force the animals to continue giving milk,factory Framing operators typically impregnate them using artificial insemination every year. Calves are taken from their mothers within a day of being born—males are destined for veal crates or barren lots where they will be fattened for beef, and females are sentenced to the same fate as their mothers.
After their calves are taken away from them, mother cows are hooked up, several times a day, to milking machines. These cows are genetically manipulated, artificially inseminated, and often drugged to force them to produce about four and a half times as much milk as they naturally would to feed their calves.
Animals are often dosed with bovine growth hormone(BGH), which contributes to a painful inflammation of the udder known as “mastitis.” (BGH is used widely in the U.S. but has been banned in Europe and Canada because of concerns over human health and animal welfare.)According to the industry’s own figures, between 30 and 50 percent of dairy cows suffer from mastitis, an extremely painful condition.
A cow’s natural lifespan is about 25 years, but cows used by the dairy industry are killed after only four or five years. An industry study reports that by the time they are killed, nearly 40 percent of dairy cows are lame because of the intensive confinement, the filth, and the strain of being almost constantly pregnant and giving milk. Dairy cows’ bodies are turned into soup, companion animal food, or low-grade hamburger meat because their bodies are too “spent” to be used for anything else.
