Which of the following best describes fortified foods?

Fortified foods are best described as those that have been enhanced with additional nutrients. This fortification process usually involves adding vitamins, minerals, or other beneficial substances to the food product to improve its nutritional profile. The primary purpose of fortifying foods is to address nutrient deficiencies in the diet of the population, thus promoting better health and wellbeing. Common examples include cereals enriched with iron or milk fortified with vitamin D.

The other choices do not accurately represent fortified foods. Foods grown without pesticides refer to agricultural practices rather than nutrient content, while foods that contain no allergens focus on safety for individuals with allergies. Lastly, minimally processed foods pertain to the degree of processing rather than the nutrient enrichment that defines fortified foods. Overall, focusing on the enhancement of nutrient content is key to understanding what fortified foods are.
