Question

who will get the most benefit from a vitamin b₁₂ supplement?

a. reproductive-age females who eat meat, fish, and vegetables every day
b. someone who eats little or no animal proteins
c. someone who consumes too many calories
d. men who eat fish, meat, and vegetables every day

Explanation:

Vitamin \( B_{12} \) is mainly found in animal - based products like meat, fish, dairy, etc. Option A: Reproductive - age females who eat meat, fish, and vegetables every day are getting \( B_{12} \) from meat and fish, so they don't need a supplement. Option B: Someone who eats little or no animal proteins has a low intake of \( B_{12} \) from diet, so a \( B_{12} \) supplement will be beneficial. Option C: Consuming too many calories is related to energy intake and not directly to \( B_{12} \) deficiency, so a \( B_{12} \) supplement won't be of most benefit here. Option D: Men who eat fish, meat, and vegetables every day are getting \( B_{12} \) from fish and meat, so they don't need a supplement.

Answer:

B. Someone who eats little or no animal proteins
