Young women who eat a typical high protein Western diet need not worry that
their protein consumption will harm their bone health.
According to research published in the latest issue of the American Journal of
Clinical Nutrition, a higher intake of protein does not have a deleterious
effect on bone density in premenopausal women.
There’s conflicting evidence about the role protein plays in bone health,
Jeannette Beasley from the Group Health Research Institute in Seattle,
Washington and colleagues note in their report. Protein in the diet from animal
and vegetable sources is important to the development of strong bones. Yet, when
protein from animal sources is digested, chemicals known to lead to bone loss
are produced.
To see if there might be a tipping point at which the risks of a diet too high
in protein outweigh the benefits for bone health, Beasley’s team analyzed data
from two large studies that looked at diet, lifestyle, and bone density in 560
women aged 14 to 40.
