Beets come in a variety of colors, including red, yellow, white, golden, and even rainbow color roots. The color of beets can be modified during cooking. Adding an acidic ingredient such as lemon juice or vinegar will brighten the color while an alkaline substance such as baking soda will often cause them to turn a deeper purple. Salt will blunt beets color, so add only at the end of cooking if needed. After cooking, the flesh of Chioggia beets turns completely pale pink. Despite the color, all beets are essentially the same when it comes to nutritional value and both add plenty of essential vitamins and minerals to your diet.
