A vegetarian diet may lower your risk for urinary tract infections (UTIs), according to a study published in Scientific Reports. Researchers tracked UTI incidence rates for 9,724 vegetarian and nonvegetarian participants. Results showed a 16 percent decreased risk for UTIs among those following a vegetarian diet. Vegetarians, of course, do not consume poultry or pork, allowing them to avoid a strain of E. coli bacteria normally associated with UTIs. They also consume more fiber from plant-based foods that better regulate gut bacteria.
