Not Medical Advice: While there are no reports that drinking 8 glasses of milk in 3 minutes could kill you, we do not recommend it, as there are reports that someone died from drinking too much water too quickly.
In 2007, a 28-year-old California woman died hours after competing in a radio station on-air water-drinking contest. After drinking six liters of water in three hours in the "Hold Your Wee for a Wii" (Nintendo game console) contest, Jennifer vomited, went home with a splitting headache, and died from a condition called water intoxication.
Water intoxication is an extreme hyponatremia (dilution of the blood caused by drinking too much water) that can ultimately cause coma and death.
As reported by The Telegraph in 2014, drinking three glasses of milk doubles the risk of early death and does not prevent broken bones.
The research that was published in the British Medical Journal suggests that it does little to strengthen bones and can double the risk of an early death.
A study that tracked 61,000 women and 45,000 men for 20 years found there was no reduction in broken bones for those who consumed the most milk.
For women it was associated with an increased chance of suffering a fracture.
Those who drank three glasses or more a day (680ml) were twice as likely to die early than those who consumed less than one.
The study’s lead author, Professor Karl Michaelsson, of Uppsala University in Sweden, said: “Our results may question the validity of recommendations to consume high amounts of milk to prevent fragility fractures. A higher consumption of milk in women and men is not accompanied by a lower risk of fracture and instead may be associated with a higher rate of death.”
Another milk risk, according to an article of SFGate, a Harvard School of Public Health study, reported in the October 2001 issue of "The American Journal of Clinical Nutrition," examined evidence suggesting that men who consumed more than 2.5 servings of dairy products per day had an increased risk of developing prostate cancer compared to men who consumed less than a half-serving of dairy per day. Men with the higher intake had a 32 percent higher risk of developing prostate cancer. A meta-analysis of available studies conducted by Tufts University and published in the December 2005 issue of the "Journal of the National Cancer Institute" reported similar findings, although the risk reported was small.
Adults don't need to drink any milk to keep your bones strong. While you do need calcium, vitamin D and other minerals to help maintain bone density and prevent osteoporosis, you can meet these needs with other foods or dietary supplements. If you like milk, however, several glasses a day can meet your needs.
Milk serves as an excellent source of calcium, with around 300 milligrams per 8-ounce glass. To meet dietary calcium requirements, women need 1,000 milligrams per day between ages 19 and 50 and 1,200 milligrams after age 51, according to the federal Office of Dietary Supplements. Drinking three to four glasses of milk would meet your calcium needs. For men, 1,000 milligrams between age 19 and 70 and 1,200 milligrams thereafter provides the calcium needed.
While calcium makes your bones strong, it takes an adequate amount of vitamin D for your body to absorb it. If you don't get enough vitamin D, you can eat large amounts of calcium and still lose bone density. Most commercially-produced milk in the United States is fortified with vitamin D, to ensure that you will absorb the calcium you get from milk. An 8-ounce serving of milk supplies around 30 percent of your daily vitamin D needs, or between 115 and 124 milligrams of vitamin D. Three glasses of milk per day would meet your vitamin D needs.
For those who don't like milk or can't drink it due to lactose intolerance or allergy, you can choose from a variety of foods -- dairy and nondairy -- to help meet your nutritional needs and keep your bones strong.
Yogurt contains more calcium per serving than milk but typically isn't fortified with vitamin D.
Different types of cheese, such as cheddar and mozzarella, also equal milk in calcium content.
Fish, including salmon or sardines canned with bones, can help meet both your calcium and vitamin D needs without milk.
If you follow a vegan diet and don't consume dairy, tofu, fortified cereals and vegetables such as kale, turnip greens and bok choy can help you meet you calcium needs. Fortified cereals often contain both calcium and vitamin D.
