According to sources such as the National Osteoporosis Foundation and the National Institute of Arthritis and Musculoskeletal and Skin Diseases, Asian American women have a high risk for osteoporosis. One of the reasons cited is that 90-percent of Asian Americans are lactose intolerant, which often times leads to an inadequate consumption of calcium in the diet without dairy products. Not having enough calcium critically affects bone health and the foundation for building and maintaining a healthy skeleton. Conversely, getting enough calcium and vitamin D everyday reduces the risk for osteoporosis as well as frequent aerobic and muscle-training exercise and avoiding smoking and drinking.
