Growth and development
Asparagus plays an essential role in foetal growth and development, during gestation, infancy and childhood. because it is rich in folate, otherwise known as vitamin B9.
Reduces the risk of depression

Amount of fibre present in asparagus also lowers the incidence and complexities during constipation, and gives a feeling of fullness which can lead to reduced appetite and therefore decrease the risk of weight gain.
The levels of potassium in asparagus reduces the incidence of heart diseases, as the American Heart association recommends people to reduce the consumption of sodium and increase the amount of potassium consumption from food.
Promotes bone health
Asparagus also helps to prevent osteoporosis, as it provides half the amount of the daily requirement of vitamin K, which is an important vitamin that has a role in the maintenance of healthy bones.
Vitamin K also works with potassium, magnesium, zinc, and phosphorus all of which have their own significant and very important role in bone health, and in increasing bone mineral density.
