Milk might not be so good for your bones after all

Drink lots of milk to strengthen your bones and boost your health, doctors say.
But a study in The British Medical Journal says Swedes with a high intake of cow’s milk died younger – and women suffered more fractures.

The findings warrant questions about recommendations for milk consumption, although further research is needed, its authors said, as the association may be purely coincidental.
A Swedish team used data taken from 61,000 women aged 39-74, monitored them for about 20 years, as well as 45,000 men aged 45-79 who they followed for 11 years.
The volunteers gave details about diet and lifestyle, body weight, smoking habits, exercise frequency, education level and marital status.
By the end of this long study period, 25,500 of the group had died and 22,000 had suffered a fracture.
Higher milk intake was not accompanied by a lower risk of fractures but “may be associated with a higher rate of death”, the study said.
Among the women, 180 per 1,000 in the group which drank three glasses of milk or more a day died during a 10-year period, compared to the group average, independent of milk consumption, of 126 per 1,000.
Among those who drank a glass or less per day, the rate was 110 per 1,000, co-author Karl Michaelsson of Uppsala University told AFP.
The figures for hip fracture was 42 out of 1,000 women who drank a lot of milk, 35 per 1,000 on average, and 31 per 1,000 of women who drank the least milk.
“Women who consumed three glasses or more per day had a 90 per cent higher risk of death, 60 per cent higher risk of hip fracture and 15 per cent higher risk of any fracture compared to those who drank less than a glass,” said Michaelsson.
For men, the difference in death rate was less pronounced: 207 per 1,000 among the three-glasses-a-day group over 10 years, 189 per 1,000 on average, and 182 per 1,000 among low consumers. There was no difference in fracture rates.
“The higher risk of mortality was evident with all types of milk: full-fat, half-fat and skimmed milk,” Michaelsson added – and started from a daily intake of about two glasses of milk.
