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.
In recent years, functional foods have gained popularity within health and wellness circles. Also known as nutraceuticals, functional foods are highly nutritious and associated with a number of powerful health benefits. For example, they may protect against disease, prevent nutrient deficiencies, and promote proper growth and development.
They promote optimal health and help reduce the risk of disease. Functional foods can be natural or processed foods that are fortified with essential nutrients or contain bioactive compounds.
