Which nutrient, converted by the body into Vitamin A, is essential for maintaining healthy vision and supporting the integrity of mucous membranes?
Answer
Beta-carotene
The nutritional benefit concerning vision provided by scallions comes specifically from Vitamin A. However, scallions do not contain Vitamin A directly in its final form, but rather contain beta-carotene. Beta-carotene is a provitamin that the human body possesses the enzymatic pathways to convert into active Vitamin A. This resulting Vitamin A is crucial not only for vision, especially in low-light conditions, but also for supporting the structural integrity of mucous membranes, which act as a primary physical defense barrier for immune function throughout the body.
