Final answer:
Athletes, particularly female and young athletes, need to increase their intake of iron to increase red blood cell production. Option b is correct.
Step-by-step explanation:
Athletes, particularly female and young athletes, need to increase their intake of Iron to increase red blood cell production. Iron is an essential mineral that is crucial for the formation of hemoglobin, which carries oxygen in the blood.
When athletes engage in intense physical activity, their red blood cell count can decrease due to increased oxygen needs. Therefore, increasing iron intake helps to support the production of new red blood cells, improving oxygen delivery to the muscles.
Foods rich in iron include red meat, poultry, fish, leafy green vegetables, and fortified cereals. Additionally, combining iron-rich foods with sources of vitamin C, such as citrus fruits or bell peppers, can enhance iron absorption.
