It is implied in the passage that bone density ----.
A low calcium intake during the growing years limits the
bones' ability to achieve an optimal mass and density.
Most people achieve a peak bone mass by about age
30, and dense bones protect against age-related bone
loss and fracture. Starting before the age of 40, all adults
lose bone as they grow older. When bone loss reaches
the point at which bones fracture under common,
everyday stresses, the condition is known as
osteoporosis. Today, worldwide, this is one of the most
prevalent diseases of aging. For instance, in the US, it
afflicts more than 25 million people, mostly older women.
Unlike many diseases that make themselves known
through symptoms such as pain, shortness of breath,
skin lesions, tiredness, and the like, osteoporosis is silent.
The body sends no signals saying bone loss is
occurring. Blood samples offer no clues because blood
calcium remains normal regardless of bone content, and
measures of bone density are rarely taken. However,
there are various strategies to protect against bone loss,
and eating calcium-rich foods is only one of them.
