here is something, pretty long tho!!! According the Physicians Committee for Responsible Medicine (PCRM)  the public is not being informed about the dangers of dairy. Currently, there is little to go on with regards to product labelling. This has many concerned as studies are increasingly growing against the milk industry.
Risk for ovarian cancer with consumption of dairy begins with milk sugar lactose. The lactose is broken down into another sugar called galactose. Finally, the galactose is broken down further by enzymes. When it becomes impossible for the body's enzymes to break down galactose, the galactose then becomes a serious issue with a woman's reproductive organs. Mostly affecting the ovaries, the inability to break down galactose via the enzymes can lead to a higher risk of ovarian cancer. According to Harvard studies, eating low fat dairy products does not reduce this risk, as it solely revolves around the milk sugar itself.
Lactose is added to many products, so reading the labels is key. While not all in the list below are derived from milk sugars, note that the manufacture may have used these words/terms to describe another addictive. In any case, it is best to avoid them all together:
artificial b___ter flavour
dry milk solids
hydrolysed milk protein
sour cream solids
sour milk solids
whey protein concentrate
Note: Bacteria added to cottage cheeses and yogurt has been shown to increase the production of galactose from the lactose in the product leading to a higher risk of all cancers.
A study conducted by Chan JM, Stampfer MJ shows how dairy affects the prostrate. Men with the highest level of IGF-I had as much as four times the risk of cancer. 
Researchers at Harvard School of Public Health released a study in April 2000 showing how dairy affects the prostate. The dietary habits of 20,885 American physicians was examined closely over a 11 year span. The study concluded that those who consumed the most dairy had developed prostate cancer. A total of 1,012 physicians who consumed moderate to high amounts of dairy came up positive for the cancer. 
A publication in the American Journal of Clinical Nutrition says there is clear evidence to link dairy consumption to prostate cancer. Those who ate the most dairy products had 17% less vitamin D in their bloodstream than those who consumed the least. Vitamin D plays a protective role against prostate cancer which the body naturally produces on its own when exposed to sunlight.
Cholesterol and Saturated Fats
Saturated fats are labelled the "unhealthy" fats. They a__sist the body in producing more cholesterol, which causes a rise in blood cholesterol levels.
Cholesterol does not break down in the blood as quickly as sugar does. It is built with insoluble protein and fat particles called lipoproteins. Lipoproteins are distributed evenly throughout our body, but in excess they can pose a serious problem to our health.
When levels of lipoproteins are high, they cling to arterial walls. This contributes to a disease known as atherosclerosis. The hardening of the arteries restricts blood flow, forcing the heart to pump beyond its capicity to keep up.
Eventually, the arteries clot and can even rupture inside of the body leading to a heart attack or stroke.
What to avoid:
Animal fats: beef, pork, lamb, chicken, turkey, b___ter, and egg yolks are all saturated fats and should be avoided.
Processed foods: Labels showing "hydrogenation" or "partially hydrogenated".
Oil:: Coconut oil, palm, palm kernel, tropical oils, lard, beef tallow.
The National Cholesterol Education Program of the National Heart, Lung and Blood Inst_tute suggests that individuals seek a total blood cholesterol screening annually. The cholesterol is measured in milligrams per decilitre of blood (mg/dL). If you consume a lot of dairy, be aware of your risks.
The desirable level should be under 200 mg/dL, while the borderline ranges between 200 to 239 mg/dL. Those who are high risk have cholesterol levels 240 mg/dL and above.
Dairy products as well as meats are contributing factors to high cholesterol levels. Products labelled as "low fat" may reduce the risk to an extent - but the fat content alone is not the main reason to put your milk gla__s down.
According to the Centers for Disease Control (CDC), the 5th leading cause of death for Americans aged between 15-34 in the year 2000 was heart disease 
Although milk may contain several components that may actually help protect against heart disease, it has shown a consistent consumption of dairy in general may have serious implications to the heart.
"More patients who had suffered a myocardial infarction had elevated levels of antibodies against milk proteins than was found in a comparable group of patients without coronary heart disease." 
Saturated fats consumed in excess increases cardiovascular disease. The amount of cholesterol found in foods is not as relevant as the amount of saturated fat.
Fatty acids from the dairy has been known to acc_mulate in blood vessels and in and surrounding tissue of vital organs. Such an invasion often leads to complications such as tumours, cysts, atherosclerotic plaque and arterial disease.
You have heard it said many times that milk builds strong bones. Yet surprisingly, osteoporosis is more prevalent in countries where dairy is part of the dietary culture.
Absence of dairy products can be noted in East and South Asia (except in India where dairy is used in moderate amounts). The plant-based, dairy-free diets have been a__sociated with low incidence of osteoporosis in Asia while the Western countries that a__sume dairy is beneficial to the prevention of osteoporosis see a disturbing rise in ailments.
Ways to help decrease the risk of osteoporosis :
eliminate animal fats
reduce sodium from the diet
exercise regularly. Light weights are shown to help keep bones healthy.
choose calcium rich foods such as dark leafy vegetables
find a qualified nutritionist
Keep in mind that not all nutritionists believe dairy is bad for you. Be sure to let her/him know of your special requirements so that they are better able to a__sist you.
Parkinson's disease is characterised by the degeneration of dopamine-producing neurons in the brain. Symptoms include tremor, muscle rigidity and movement problems. The cause of PD is still unclear, but it is thought likely to be a combination of ageing, environmental factors, and genetics.
A study headed by Dr. Honglei Chen of the Harvard School of Public Health in Boston, Ma__sachusetts, investigated the a__sociation of dairy intake and onset of PD in two groups of 47,331 men and 88,563 women. The study ran from 1980s to 1998, where 210 men and 184 women developed PD. It was also noted that They said 53% of stomach cancer patients and 55% of oesophageal cancer patients ate either the high-meat or high-milk diets. 
Allergic Reactions - Adults
Of all food allergies, dairy tops the list of most frequent cases. The proteins found in bovine milk, may trigger varied reactions. The most obvious reaction surrounds respiratory problems.
Casein and whey are the two main triggers to the allergic reactions. When milk is left to sour and solidify, curd is formed which called casein. The softer the cheese created, the less casein. The bulky, hard cheeses contain concentrated amounts of this protein.
The water left over after draining the casein is called whey. In whey, two proteins are identified as allergy causing - alpha-lactalbumin and beta-lactaglobulin.
A Milk allergy typically makes itself known in the early stages of infancy. Although it is estimated that 2 to 3% of infants are allergic to milk, most end up outgrowing it in their first few years of life. A certain percenatge unfortunately are never able to overcome the allergy and are thus unable to consume any dairy.
Respiratory Complications - Children
Glazed look in the eyes
Non-responsive to verbal commands
Bed wetting without obvious cause
As with any food allergy, age does not necessarily discriminate. An adult who never had a problem with drinking milk can suddenly find herself or himself in the throws of allergic reaction. Some symptoms mild - to the point where it is never properly diagnosed. Meanwhile others suffer immediate reactions that are too hard to ignore.
Shortness of breath
In addition to the respiratory reaction to milk allergy, skin reactions and digestive problems can point an individual or trained allergist into the right direction.
With skin reactions, one may notice dark circles under the eyes or even "black eyes", an isolated or generalised rash, hives, and swelling in or more areas such as the tongue, lips, throat, face or eyelids.
With digestive system reactions, look out for abdominal cramping, bloating, a "full" feeling, nausea or vomiting, or persistant gas.
There are quite a few great alternatives to dairy one can look into such as soy milk and rice and almond milk. Provided you do not have an allergy to these three alternatives, you will find them natural, nutritious and versatile with many of your recipes.
Autism and Schizophrenia
According to a November 2002 lawsuit filed in New Zealand's High Court, Fonterra tried to suppress a research campaign that linked milk with autism in children. Fonterra is considered a dairy giant in NZ. Once known as NZ's Dairy Board, Fonterra produces for brands such as Bega, Mainland, Peters, and Tip Top.
The research itself relates to a protein in A1 milk, which is the most commonly produced milk in Australia. The protein beta casein A1 is also a risk factor for childhood diabetes and coronary heart disease.
The autism research had been in the public domain even before the 1999 publication of two key animal studies which indicated cases of autism and schizophrenia may be linked to an individual's inability to properly break down a protein found in milk.
A University of Florida physiologist, Robert Cade, said the digestive problem might actually lead to the disorder's symptoms. When not broken down, the milk protein produced exorphins, morphine-like compounds that are then taken up by areas of the brain known to be involved in autism and schizophrenia, where they cause cells to dysfunction.
Dr. Cade said a high proportion of autistic and schizophrenic children studied had as much as one hundred times the normal levels of the milk protein in their blood and urine. However, when the children were put on a dairy-free diet, at least eight out of ten showed no signs of autism or schizophrenia.
During the laboratory studies conducted on animals, researchers injected rats with the protein beta casomorphin 7 (BCM-7) one of the key const_tuents of milk and the part that co-agulates to make cheese.
Beta casomorphin 7 had taken up by thirty-two different areas of the brain, which included sections responsible for vision, hearing and communication. This, researchers say, explains the hallucinations, autism and schizophrenia symptoms.
Normally proteins are digested by enzymes in the intestines being broken down into these units. However, if for some reason, this digestion is incomplete, short chains of these amino-acids which are known as peptides will result. It is proposed that these peptides may be biologically active and could result in the symptoms which we see in autism. 
BCM-7 is also the common denominator concerning the infant formula known as Pregestimil. Research has shown that Pregestimil, a hypo-allergenic formula, was shown to produce a high level of diabetes in rats in the Food and Diabetes Trial carried out by Professor Bob Elliott.
What is A1 and A2 Milk?
The are six major proteins found in cow's milk. Four are "casein" proteins and the other two are "whey" proteins. The caseins usually make up about 80% of the protein in cow's milk.
One of the major caseins is beta-casein. There are different b-casein types, but the most common are beta-casein A1 and beta-casein A2.
Certain breeds of cows produce mostly A1 milk, whereas other breeds, such as Guernseys, and also sheep and goats, produce mostly A2 milk. The milk produced in Australia and New Zealand is normally a mix of A1 and A2 milks.
Milk has been reported to trigger Ulcerative Colitis, and people with UC were found to have anti-bodies to milk in their blood, a possible sign of allergy. 
Researchers convinced that Multiple Sclerosis is an auto-immune disease have now made a definite connection between MS and dairy consumption.
Roughly 300,000 american men and women are stricken with MS annually. The highest numbers of anywhere in the world. Again, the west consumes the most dairy in the world. Eskimos and Bantus (50 million individuals living in East Africa) have the fewest incidence of MS cases.
Two-thirds of MS victims are women which can be directly linked to those who consume a greatest amount of dairy.  Completely eliminating all dairy from one's diet can significantly reduce MS symptoms and even MS itself. 
In a very detailed study published in the journal Neuro-epidemiology explained the a__sociated between dairy and an increased liklihood of MS. 
According to Dr. McDougall, Among patients whose saturated fat intake was 17 grams or less daily, the death rate over a 35-year-period was 31 percentclose to normal. The death rate was 21 percent for the patients who kept to that low level of fat consumption and who started the diet within three years of diagnosis of the disease. On the other hand, patients consuming more than 25 grams of saturated fat daily had a death rate of 79 percent over the period of the study; nearly half of those deaths were directly due to MS. 
What Consumers Want
American consumers have indicated overwhelmingly that they do not want milk that contains genetically-engineered hormones, and that they want milk labelled so they can make an informed choice in the grocery store. 
Wisconsin, the leading dairy-producing US state, conducted a survey asking 1,000 people if they would prefer dairy products announce if the synthetic hormone called Recombinant Bovine Growth Hormone (rBGH) has been added. Over 75% said they would be willing to pay extra for the labelling to avoid consuming the hormone unknowingly. 
Insulin-like Growth Factor (IGF-I)
Insulin-like Growth Factor (IGF-I) is a genetically engineered hormone produced by Monsanto Company, a leader in the agrichemical industry.
Cow's milk increases our cancer risk due to an rise of a compound called insulin-like growth factor (IGF-I) in our bloodstream. The IGF-I becomes a problem in those who consume dairy products such as milk, cheese, yogurt, b___ter and ice cream on a daily basis.
IGF-1 may promote the growth and invasiveness of cancer by creating a "apoptosis". Apoptosis is when the natural self-destruction of cancer cells is suddenly inhibited from following its course.
What happens to the cows?
Although Posilac serves its purpose by increasing the production of milk, it also causes the cow to suffer uterine disorders, bacterial infections, mast_tus, and it promotes cyst growth on the ovaries.
When a cow is suffering from a bacterial infection of the udders, pus forms. This pus along with blood is sucked into the machinery along with the milk. The contaminated the milk supply and is packaged, processed and delivered to the market for retail sale.
Along with the mishandling of milking, it should be noted that cows are kept pregnant constantly to create a steady business with the veal industry. Cows are artificially inseminated, by what the industry coined the "rape rack", given a series of anti-biotics and hormones to maintain the pregnancy.
All male calves are sold quickly as they hold little value to the dairy famers. They are carefully put away and sold quicky to veal farmers where they are slaughtered.
The female calves remain on the farms to be raised until maturity where they will be used for milk production and breeding. Cows normally have a life expectancy of between 27-30 years but due to mistreatement, most never make it to 5 years old.
What The Dairy Market Isn't Telling You
Substantial evidence indicates that milk from rBGH-treated cows are very likely to include pus production from the cow's udders into the product, tumour-promoting chemical called IGF-I is more present in the dairy, which has been implicated in cancers of the colon, smooth muscle, and b___st and further anti-biotic use to treat the infection.
According to the Consumers Union, it is estimated that rBGH will cost the American taxpayer upwards of $200 million or more annually.
People should not confuse the benefits of calcium with dairy. The dairy industry has stressed the benefits of calcium, but not dairy itself. Dairy is big business so it would be in the industry's best interest to keep the fallacies alive.
The Food and Drug Adminstration (FDA) and Monsanto joined forces to implement a system that would produce more milk by using hormones that are banned in all other parts of the world.
The USDA convinces the American public to drink more milk while it openly subsidises large dairy farms and federally mandates dairy consumption for all schools. The U.S. government spends billions to purchase unused milk and dairy products, one of the biggest forms of subsidies.
Marketing alone went upwards of $200 million last year and the price is steadily rising. A drop in the bucket for what consumers purchase annually, leaving the government with a chunk of profit.
In The Media
University of Tennessee Research Presented at the 1999 North American a__sociation for the Study of Obesity (NAASO) Annual Meeting in November of 2002 is convinced that a diet high in calcium from low fat dairy foods, such as milk, yogurt and cheese, has been found to help control body fat.
As the news streams out among the public on the dangers of dairy, there is a race to prove the findings wrong. By giving false hope to those who are overweight or obese, it will cause further medical disasters and is considered irresponsible by most.
Finally for those who believe that dairy is a factor in weight loss, keep in mind that the study is promoted by the National Dairy Council's Nutrition and Health News Bureau. 
PS my ex was a nutrtionist, studied like a nerdddd on nutrition and he wouldn't touch dairy at all. my doctor also told me that dairy isn't very healthy for women as once thought. showed me a chart from a study a friend of his was participating in that showed the acidity level of bovine milk in the blood, which were compared to bone density levels in women over the span of 18 months. i was sold.
