Bone mass inevitably decreases as we age, making us more susceptible to bone fractures and back pain. This is a condition known as osteoporosis, which over 10 million americans struggle with. Women are much more likely to develop osteoporosis, and having a family history also increases your likelihood. One of the biggest factors in this condition is lies in how much bone mass you had to begin with, which usually reaches its peak in your early twenties. Other risk factors include: lack of calcium and vitamin c, a high sodium intake, smoking, and an inactive lifestyle.
