Eating tomatoes every day, with a spoonful of concentrated tomato puree added, protects the skin against UV light from the sun. The red pigment in tomatoes is called lycopene. Lycopene is a carotenoid antioxidant that may also have other health- promoting effects.
The pigments in the Colourful vegetables have great health benefits, so it is worth growing different coloured veg.
