Do superfoods really exist?
A so-called ‘superfood’ has no scientific definition and the word is little more than a marketing fad. Fruit and vegetables rich in antioxidants, like blueberries, kiwi fruit and goji berries, often top the superfood list. Antioxidants, such as vitamins A, C and E, are billed as being able to fight havoc-wreaking free radicals, helping to prevent cancer. But evidence for dietary antioxidants’ effectiveness is sparse, with some studies suggesting that digestion destroys much of the antioxidant power of berries. Plus, the antioxidant concentrations needed would require you to consume vast quantities of your selected superfoods. However, the foods are all healthy and will enrich a balanced diet. ED
