Fancy a little flower with your tomatoes? Not flour, flower – as in snapdragons. Researchers found that by injecting genes from snapdragon flowers into normal red tomatoes, the latter produced an increased amount of the pigment anthocyanin. Besides adding deep reddish and bluish tonnes to fruits like cranberries and blackberries, anthocyanin is a potent anti-oxidant that shows promise in inhibiting the growth of cancer cells, easing the symptoms of diabetes and relieving a number of age-related illnesses. Should human trials pan out, you may be seeing healthy purple pizza on the menu some day!
