What are Functional Foods?

What are functional foods?

Functional foods are defined as foods that have disease-preventing or health-promoting benefits in addition to their nutritive value. These additional benefits extend further than just macronutrients like protein, fat, and carbs. They also include beneficial compounds like omega-3s, antioxidants, and specific beneficial compounds. The term was initially coined in 1984 in Japan to describe a “tertiary function” in food, coming behind primary general nutrition and secondary taste preferences. Functional foods are all around us and contribute to our health every day. It should be noted that while functional foods can not single-handedly cure or prevent illness on their own, they are beneficial when included in a balanced, healthy diet. Positive lifestyle choices, such as regular exercise, proper sleep, and stress management also play a role. 

Different Types of Functional Foods

Tropical fruits are loaded with nutrients for overall good health.

There are many different types of functional foods from different sources. There are foods that have been enriched, meaning nutrients that were lost during food processing have been added back in. Fortified foods contain a new nutrient that is not naturally found in the food, but has been added in. Take vitamin D in milk, for example. Some foods have been altered (i.e. reducing the fat content in skim milk, or low-fat peanut butter) or enhanced (eggs that have more omega-3 because the chickens have more omega-3’s in their feed). And then, there are foods that are not altered and are labeled as functional when naturally grown. Each of these categories is described as functional because they offer nutrients that are beneficial to our health. However, in this article, we’ll be focusing on the naturally occurring functional foods for all-around good health.

Fungi include yeasts, molds, and mushrooms. This food group may have antioxidant, antitumor and antimicrobial properties. Interestingly enough, mushroom proteins are complete proteins, meaning they contain all nine essential amino acids that you require from food. Try adding some mushrooms or other types of fungi, like nutritional yeast to your next meal. Molds found in cheeses are also good options!


Seafood is a super healthy functional food.

Seafood contains so many fantastic nutrients like lean protein, beneficial omega-3s, and special minerals like zinc and selenium that are important for fertility and skin health. Different types of seafood include fish and shellfish. No matter what the source, these ocean-based foods may reduce risk of cardiovascular disease and even improve brain and eye function.

Avocado and coconut are excellent sources of healthy fats, great for skin and hair health. 


Tea is one of the best functional foods!
