Dynamic duo

Some things just work better in pairs. Martin and Lewis, Hanz and Franz, Ramirez and Ortiz, Tom and Jerry -- all play very well off the other, creating a synergistic effect for laughs, baseball, and cartoon antics. But synergy of this kind can also be found in food; avocado and spinach seem to work better together than when eaten individually.

The high monounsaturated fat content in avocado helps you absorb more of the nutrients found in spinach when the two are eaten together. Specifically, you'll absorb about five times more lutein and 15 times more beta-carotene, making each of these healthy foods worth enjoying together.

For a tasty way to audition this healthy pair, try adding a half an avocado to the top of your next spinach salad.
