Our kitchen sink is white. I'm not sure who picks out "standard" colors for such things as sinks, but I tell you, it's probably not someone who cooks healthy foods. Same goes for any clothing manufacturer who makes a kid's garment in white. Or, heck, one of my shirts, too.

What in the world, you say, does the color of your sink and your clothes have to do with healthy food? Well, I have this theory that if a food doesn't contain artificial colors and it stains permanently, it must be good for you. Let's put it to the test here.

Beets. The red ones get their crimson color from a phytochemical called betacyanin. This compound is also a powerful cancer-fighting agent.
