One cup of asparagus provides a staggering 110% of vitamin K needs (vital for bone health) and more than 60% of folate (a B vitamin key that's key to a healthy pregnancy) needs. This super veggie also supplies over 30% DV of copper, a mineral that plays an important role in protecting blood cells and other parts of the body. That's not all—asparagus also contains compounds called saponins, which have anti-inflammatory action! This means that microscopic damage that can occur in body cells is literally calmed down, which research shows lowers risk of blood vessel disease and damage to nerve fibers due to aging. - Dr. Liz Applegate
