Which of the following is an example of a nutraceutical?

A nutraceutical is a term used to describe food products that have health benefits beyond basic nutrition, often derived from natural sources. Herbs are a prime example of nutraceuticals because they contain bioactive compounds that can promote health and prevent disease. Many herbs have been found to have medicinal properties, such as antioxidant effects or anti-inflammatory benefits, which support their classification as nutraceuticals.

In contrast, while whole grains, meat, and dairy products are nutritious food sources, they are primarily considered sources of macronutrients (carbohydrates, proteins, and fats) and do not typically convey the additional health benefits associated with nutraceuticals. Whole grains offer fiber and essential nutrients, meat provides protein, and dairy products deliver calcium and vitamin D, but they do not share the specific health-enhancing properties linked to herbal compounds commonly recognized in the nutraceutical category.
