What are functional foods?

Functional foods are defined as foods that provide health benefits beyond basic nutrition, which is exactly why the second option is correct. These foods can have specific components that contribute to improved health or a reduced risk of diseases. For instance, foods enriched with omega-3 fatty acids, probiotics, or certain antioxidants can enhance overall wellness and support bodily functions in ways that standard nutrient profiles do not.

In contrast, the other options lack the comprehensive health-related context that defines functional foods. Foods that are solely for taste do not necessarily offer health benefits; they might prioritize flavor without any nutritional advantage. Foods that are only high in calories might contribute to energy intake but can lack essential nutrients or health benefits. Similarly, foods that lack nutritional value do not support health and wellness at all, making them the antithesis of what functional foods represent.
