Not all, but most. I don't notice much of a difference with peppers or carrots, but strawberries especially are incredible when grown from a garden and pretty tasteless when bought from a store. Tomatoes don't have quite as significant of a difference, but they're still much better. I don't think I've ever gotten fresh beets from anywhere but a farmer's market or my garden, so I'm not sure about them.
