Question

Quizplus · Accepted Answer

Calcium-fortified orange juice is the best example of a functional food because it has been enhanced with a nutrient (calcium) that provides a health benefit beyond its basic nutrition. Tomatoes and oatmeal are healthy foods, but they are not necessarily functional foods. White bread, on the other hand, lacks many important nutrients, and does not provide any additional health benefits beyond basic nutrition.
