Not only are colorful vegetables a bright addition to your vegetable garden, different colors often signal added health benefits. Eating a variety of colorful foods means you’ll eat a broad range of phytochemicals and phytonutrients, which are “beneficial substances produced by plants” that help reduce your risk of cancer and heart disease.  Here are a few nutritional highlights for some of the colorful vegetables on our list: --Vitamin A: Eat one sweet potato or one cup of kale (or swiss chard) for a full day’s worth of vitamin A. --Vitamin C: A single cup of cooked tomatoes will fulfill nearly 100% of your daily vitamin C requirements. --Antioxidants: Vegetables are rich in antioxidants such as carotenoids and lycopene that may have positive effects on human health. --Finally, fresh, colorful vegetables that you grow yourself just taste better.
