Chances are, you zip in and out of the produce section after grabbing a few familiar staples: apples, cucumbers, broccoli, bananas. “We’re creatures of habit—if we like something, we tend to repeat buy,” says Frances Largeman-Roth, RDN, a nutrition expert and author of Everyday Snack Tray. “In the case of fruits and vegetables, we may avoid purchasing something new because we’ll likely have to spend time and energy learning how to make it.”
But incorporating some lesser-known produce into your diet will not only add excitement to your meals, it may also help you live longer. “A thriving gut microbiome relies on diversity, and incorporating a wide variety of produce in your diet is essential for optimal health,” says Largeman-Roth.
