Which of the following is the best source of dietary vitamin B12?
a. Fruit
b. Green vegetables
c. Meat
d. Legumes
ANS: C
Meat provides the best source of vitamin B12; meat byproducts such as milk and eggs are sources other than meat. Plants have no need for this vitamin, and so it is not available in green vegetables, legumes, or fruit. Thus it is possible, over time, for a true dietary deficiency to develop for a strict vegetarian (i.e., vegan).
