Eat the rainbow. It is incredible to see the wide variety of colors of various fruits and vegetables available when we have become accustomed to just one, maybe two, in the supermarket.
Carrots come in reds, yellows, purples, whites, and oranges. These were all selectively bred from mutations of wild varieties over thousands of years. However, we predominantly see orange carrots, which rose to popularity when the Dutch started selectively breeding the orange mutations in the 1500s. They were favored for their sweetness and lack of stain that some purple varieties had, and have become the standard varieties we see today.
These different colors have different vitamins and antioxidants for our health, like beta carotene and anthocyanins. Beyond the health benefits and nuanced flavor that a lot of these different colored vegetable varieties offer, they are also just fun. People enjoy the novelty of seeing and tasting the different colors when we have become so accustomed to the standard supermarket varieties.
