As we age, our bone density declines, making us prone to osteoporosis. Surprisingly, women are more prone to developing osteoporosis as compared to men due to thinner bones and a drop in the level of estrogen (a hormone that protects bones), which decreases when women reach menopause. It is important to add more calcium-rich food to the diet for better bone health. For women aged 50 and younger, the minimum daily calcium requirement is 1,000 milligrams (mg) a day, while for those over 50 it is 1,200 mg.
