How Phytochemicals Work


Phytochemical Reference Table

­Each different colored vegetable or fruit contains certain types of phyt­ochemicals. If you're looking for a particular vegetable that isn't here, look up a similarly colored food -- chances are, it contains the same types of phytochemical. For instance, kale has the same types of phytochemicals as broccoli.
