As stated, calcium is a threshold nutrient; therefore, the
increase in bone mass from an adequate intake of calcium
will give greatest effi ciency in bone metabolism when other
nutrients are coparticipants.
The contribution of these nutrients may come from fruit
and vegetable consumption, as there is a positive correlation
between these and bone mass in girls and in boys, at
prepubescent and adolescent ages [40,102], and in adults
[103,104]. However, much controversy exists on this matter
because no relationship has been reported in other studies
[105].
