Functional foods are foods that offer health benefits beyond their nutritional value. In addition to nutrient-rich ingredients like fruits and veggies, the category also includes foods fortified with vitamins, minerals, probiotics, and fiber. Functional foods are ingredients that offer health benefits that extend beyond their nutritional value. Some types contain supplements or other additional ingredients designed to improve health. The concept originated in Japan in the 1980s when government agencies started approving foods with proven benefits in an effort to better the health of the general population (1Trusted Source). Some examples include foods fortified with vitamins, minerals, probiotics, or fiber. Nutrient-rich ingredients like fruits, vegetables, nuts, seeds, and grains are often considered functional foods as well. Oats, for instance, contain a type of fiber called beta glucan, which has been shown to reduce inflammation, enhance immune function, and improve heart health (3Trusted Source). Similarly, fruits and vegetables are packed with antioxidants, which are beneficial compounds that help protect against disease (4Trusted Source).
