Seniors have a particularly high risk of breaking bones because the natural growth of bone tissue slows with age. Without a proper diet, bones become brittle and less dense as we get older. To prevent osteoporosis, many doctors recommend that seniors ingest more calcium, which builds bone cells, and vitamin D, which aids in calcium absorption Consuming foods rich in calcium, vitamin D, and other nutrients preserves bone tissue. Adults over the age of 50 should get 1,200 milligrams of calcium and up to 600 international units of vitamin D each day. Eating a combination of the following foods provides the essential nutrients for bone health.
