Improves bone health

Collard greens are high in calcium and vitamin K, both of which are beneficial to bone health. In fact, 1 cup (170 grams) of these cooked greens has 27% of the daily need for calcium and 883 percent of the daily value for vitamin K. Almost bulk of the calcium in your body is stored in your bones and teeth, where it helps to sustain their structure and function.

If you don't receive enough calcium for an extended length of time, your bones may begin to deteriorate, making them thinner and more prone to fractures. This occurs because your body need the stored calcium for other vital processes such as nerve communication and muscular action. Calcium supplementation is very crucial for older persons, particularly postmenopausal women. It can assist to slow the natural aging process of bone loss.

Meanwhile, vitamin K stimulates the activity of proteins that support bone health and metabolism. Many older and recent observational studies, for example, believe that a lack of vitamin K may be associated with an increased risk of bone fractures. However, controlled investigations have proven inconclusive, suggesting that additional study is required.
