Next time you have a meal, look at your plate -- what colors do you see? If it's mostly white and brown then your diet might be colorblind!

In order to have a healthy diet you need foods from all the food groups, and that means a colorful plate. Just eating meat and potatoes won't provide you with the essential vitamins and minerals you need to stay in your best health -- you need to add in colorful fruits and vegetables!

If you want a balanced diet, here are some colors you might want to see next time you look down at your plate:

Green

Green-colored foods like peas, kale, spinach, honeydew melons, kiwifruit, dark leafy lettuces and leafy greens contain lutein, which helps maintain good vision and can help reduce the risk of macular degeneration and cataracts.

Another green group includes broccoli, cabbage, bok choy, Swiss chard, Brussels sprouts, rutabaga, turnips, cauliflower, and watercress. These foods contain indoles, which can help reduce the risks of cancer and reduce tumor growth in cancer patients.
