What are Superfoods? The term superfoods entered the language in the 1990s to denote foods packed with nutrients that supposedly have health-giving properties. Some are exotic, such as alfalfa, spirulina and wheatgrass, and some prosaic such as broccoli, beans and beetroot.
At a very basic level, superfoods are said to be rich in particular nutrients. This could be an antioxidant, thought to ward off cancer; a healthy fat, thought to prevent heart disease; fibre, thought to prevent diabetes and digestive problems; or phytochemicals, the chemicals in plants responsible for deep colours and smells, which can have numerous benefits to health.
