Question

which statement is not true of vitamin e?
o a. vitamin e deficiency can cause hemolytic anemia in premature infants.
o b. dietary vitamin e requirements increase with increasing intakes of polyunsaturated fats.
o c. vitamin e is the most toxic of all the vitamins.
o d. vitamin e is easily destroyed by heat and exposure to air.

Explanation:

• Option a: Vitamin E deficiency can cause hemolytic anemia in premature infants, this is a known fact.
• Option b: As polyunsaturated fats are prone to oxidation, more vitamin E (an antioxidant) is needed when their intake increases, so this is true.
• Option c: Vitamin E is relatively non - toxic compared to other vitamins (e.g., vitamin A can be highly toxic in excess), so stating it is the most toxic of all vitamins is false.
• Option d: Vitamin E is sensitive to heat and air, which can cause its degradation, so this is true.

Answer:

c. Vitamin E is the most toxic of all the vitamins.
