High cow’s milk intake is associated with increased risk for bone fractures and death, according to a new study in the British Medical Journal. Researchers followed 61,433 women and 45,339 men for more than 20 years and 11 years, respectively.
Among women, those who consumed three or more glasses of milk per day had a 60 percent increased risk for developing a hip fracture and a 16 percent increased risk for developing any bone fracture. These results are similar to previous studies showing no protective effect of increased milk consumption on fracture risk.
Additionally among women, for each glass of milk consumed, risk of dying from all causes increased by 15 percent, from heart disease by 15 percent, and from cancer by 7 percent. For the women who consumed three or more glasses of milk per day, compared with less than one glass, risk of dying increased by 93 percent. Men had a 10 percent increased risk of dying when consuming three or more glasses of milk per day, compared with less than one glass.
