What’s the best diet? The truth is, medical research supports a variety of eating patterns, each of which can be tailored to an individual’s health needs.

To help you build a strong foundation, here’s a list of whole foods to prioritize and foods to limit for overall health. Follow these simple guidelines, and you’ll be well on your way to feeling your best.
