Because of our busy every day, then we rarely take the time to exercise. Though exercise is an important factor to make our bones strong, even exceeding the benefits we derive from consuming calcium.
Indeed, this study is mainly aimed at teenage girls and women, because of the risk of osteoporosis or brittle bones more often experienced by women, especially after menopause. It is due to decreased estrogen.
Bone mass continued to be built until reaching the age of 20-25 years, most built in the early and mid-teens. And after that, no more bone mass is built, instead gradually decreases with increasing age. And decreases rapidly at menopause. So to build strong bones during adolescence, will prevent us from having osteoporosis in the elderly.
Calcium is very important for bone health, but if it is not accompanied with the sport has only little effect on bone strength. The recommended intake for adolescent girls according to the Journal of Pediatrics, is equal to 1,300 mg per day.
