Which of the following is NOT a source of vitamin D?

• A. Salt
• B. Sunlight
• C. Fatty fish
• D. Fortified milk

Answer: (A)

Vitamin D comes from two main avenues: your skin can synthesize it when exposed to sunlight, and certain foods provide it. Fatty fish is one of the natural dietary sources, and fortified milk (and other fortified foods) help people meet vitamin D needs. Salt, however, is not a source of vitamin D; it mainly supplies sodium and chloride, and sometimes iodine, but not the vitamin itself. So salt would not contribute to vitamin D status, whereas sun exposure and the listed dietary sources do.
