Question

Which of the following statements are incorrect?

(i) Vitamin A helps to prevent night blindness.
(ii) Vitamin C prevents rickets.
(iii) Vitamin K helps in clotting of blood.
(iv) Iron helps to prevent goitre.
(v) Potassium helps to regulate fluid balance in our body.

Answer 1

• Vitamin C stops internal bleeding, prevents infections and strengthens blood vessels but it does not prevent rickets. Rickets can be prevented by supplying enough vitamin D to the body.
• Iron helps in transportation of oxygen to different parts of the body as it is a constituent of haemoglobin. It does not prevent goitre. Iodine helps prevent goitre.
