Which organization recommends that people NOT use supplements to prevent chronic diseases?

• A. FDA.
• B. NIH.
• C. WHO.
• D. CDC.

Answer: (B)

The main idea is that for preventing chronic diseases, relying on dietary supplements isn’t supported by solid evidence. The NIH, especially through its Office of Dietary Supplements, emphasizes that supplements are not a substitute for a healthy diet and regular activity. Large studies haven’t shown consistent, general benefits from vitamins, minerals, or other supplements in preventing chronic diseases, and in some cases they may even cause harm. So the authoritative takeaway is to focus on proven lifestyle strategies and use supplements only for specific deficiencies or under medical guidance. Other organizations regulate safety and provide broad guidelines, but they don’t issue the same blanket stance as the NIH regarding disease prevention through supplements.
