question 47
which of the following statements about antioxidants is false?
a vitamins e, c and carotenoids have antioxidant properties.
b antioxidant supplements are proven to reduce the risk of cancer and cardiovascular disease
c antioxidants scavenge free radicals to minimize oxidative damage.
d none of these statements are false.

Explanation:

• Option A: Vitamins E, C, and carotenoids do have antioxidant properties. This is a well - known fact in nutrition and biochemistry.
• Option B: Antioxidant supplements have not been "proven" to reduce the risk of cancer and cardiovascular disease. While there is some research suggesting potential benefits, large - scale, well - controlled clinical trials have not consistently shown a definitive reduction in these risks.
• Option C: Free radicals are unstable molecules with unpaired electrons that can cause oxidative damage to DNA, RNA, lipids, and proteins. Antioxidants can scavenge these free radicals to minimize oxidative damage.

Answer:

B. Antioxidant supplements are proven to reduce the risk of cancer and cardiovascular disease.
