Probiotics are all the rage among health nuts, but one can only eat so much yogurt. To get more of the good-for-you gut bacteria, try a tangy summer side of fermented pickled vegetables. "Fermented veggies promote healthy microorganisms in your gut that aid digestion and boost your immune system," says Frank Lipman, MD, of Eleven Eleven Wellness Center in New York City. And that helps prevent a surplus of bad bacteria that can lead to inflammation, obesity, and other chronic diseases that start in your gut, he says. Probiotics may prevent food allergies and obesity, too, by changing how our gut filters allergens and molecules that create inflammation. Sounds good to us—and so does this yummy pickled beets and cauliflower recipe! The fermentation process takes several weeks, so plan in advance.
