Does milk help prevent fractures?
Milk is by most people believed to help support bone formation and reduce the risk for fractures, but is that true?
The following research investigated milk intake and the risk of mortality and fractures in women and men (Michaelsson K, et.al., 2014).
This study was done in Sweden and included 61,433 women and 45,339 men. The average follow up for the women was 20.1 year and for the men 11.2 years.
High milk intake was associated with higher mortality for both women and men, and with a higher fracture
incidence in women.
It’s common to recommend milk for teenagers to promote increased bone mass.
To determine whether milk consumption during teenage years influences the risk of hip fracture in older adults, the researchers of this study included both women and men and did 22 years of follow-up (Feskanich D, et.al., 2014).
After controlling for known risk factors and current milk consumption, each additional glass of milk per day during teenage years was associated with a significant 9% higher risk of hip fracture in men.
It was concluded that greater milk consumption during teenage years was not associated with a lower risk of hip fracture in older adults.
These studies were population studies using food frequency questionnaires which is not as accurate as double blinded research comparing 2 groups.
However, when the research includes large population groups and both show the same results, it’s worthwhile to pay attention to the results.
