Collard greens are a member of the Brassica genus of plants, just like broccoli, cabbage, and kale. Just like other Brassicas, collard greens are packed with nutrition and provide many health benefits when eaten regularly as part of a healthy diet.
 
Collard greens are rich in potassium, which is important for regulating your heartbeat, helping your muscles contract, and balancing out the effect of salt on your body. 
 
Collard greens also have a low glycemic index rating, which means they won’t cause your blood sugar to spike after eating.
