Which essential mineral, vital for oxygen transport via red blood cells, is present in black beans?
Answer
Iron
Iron is classified as an essential micronutrient crucial for systemic health, particularly within the circulatory system. Its primary function involves being a fundamental component of hemoglobin within red blood cells. Hemoglobin is the specific protein responsible for binding to oxygen molecules in the lungs and efficiently transporting that oxygen to tissues and organs throughout the entire body. While black beans also contain other vital minerals like Magnesium, Manganese, and Folate, Iron fulfills the specific role described concerning oxygen transport.
