Alopecia areata causes hair to fall out in big patches. The culprit is your own immune system, which attacks healthy hair follicles by mistake. In most cases, the damage isnât permanent. The missing locks should grow back in 6 months to a year. Some people lose all the hair on their scalp and body, but thatâs rare.
When it comes to building strong bones, there are two key nutrients: calcium and vitamin D. Calcium supports your bones and teeth structure, while vitamin D improves calcium absorption and bone growth.
Building a higher peak bone mass early in life helps prevent osteoporosis later in life. It is essential to eat enough calcium-rich foods and do regular physical activity (high impact or weight bearing) during the first twenty years of life to help achieve a healthy maximum bone density.
