Orange and yellow fruits such as the carrots and corns are good for our vision. White fruits are good for the immune system and prevent cell inflamation. Blue fruits protect us afrom harmful UV rays and purple fruits slow down the aging process. The colours of the fruits are due to the pigments and these contain phytonutrients which incidentally has high levels of antioxidants. Yes, I suppose you can judge a fruit by its colour!
