Purple asparagus has an abundance of fiber, potassium, and vitamin B6. It has a sweeter flavor than its counterpart, green asparagus. There is little difference between both veggies. A serving of 90-gram asparagus provides over one-third of the folate your body needs. 

The B vitamins prevent anemia and promote a healthy heart. It contains thiamin and riboflavin, two compounds necessary for growth and development. Overall, asparagus is an excellent addition to meals because it promotes good health.
