5 Foods That Fight UTIs

If you're susceptible to urinary tract infections (UTIs), you may want to tweak your diet. And yes, this goes way beyond drinking cranberry juice.
In a new study inThe Journal of Biological Chemistry, scientists from Washington University School of Medicine in St. Louis found that the foods we eat—or rather, the small molecules created when we digest food—as well as the acidity of our urine, influence how well bacteria can or cannot grow in our urinary tracts. And while conventional wisdom has held that more acidic urine is less hospitable to bacteria, this study turns that idea on its head. (Are your hormones throwing your body out of whack?

The Crazy Science Happening In Your Urethra
"We didn't set out to link diet to urinary tract infections at all," says study author Jeffrey Henderson, MD, PhD, assistant professor of medicine and molecular microbiology at the Washington University School of Medicine. "We were looking at immune response—how the body naturally fights infections." Their goal was to learn how the body kills a strain of bacteria calledEscherichia coli(E. coli), the most common cause of urinary tract infections (UTIs), since wide use of antibiotics is contributing to bacterial resistance. In the last 10 to 15 years alone, Henderson has seen a jump in UTIs that are resistant to antibiotics.

The team collected urine samples from healthy volunteers and cultured them with E. coli to see if there were differences in how well they tamped down bacteria. "Your body makes a protein calledsiderocalinthat is known to control bacterial growth, and it shows up in the urine of people with UTIs, like the body's first responders," Henderson explains. The researchers then looked to see if levels of this protein functioned differently across the individual urine samples—and indeed, there were surprisingly large differences.

Further sleuthing uncovered two main reasons why some people's urine showed greater bacteria-fighting power: (1) Certain compounds from their diet—either directly from the foods they eat or as byproducts of digestion—help siderocalin do its job, which is to deprive bacteria of iron, a mineral it needs to grow. "Siderocalin uses these dietary compounds as molecular grips to bind to iron and keep it away from the bacteria," Henderson says. "If you can keep iron away from the bacteria, you prevent it from growing." (2) Their urine had a higher pH, meaning it was closer to neutral, almost like water. According to Henderson, the protein binds to iron far more effectively when the urine is at a higher pH.

So What Should You Eat?
Which nutrients can help deploy the body's first responders to stop a urinary tract infection in its tracks? Henderson's research points to polyphenols, a type of antioxidant. And while generally antioxidants work by scavenging free radicals in the body to prevent them from causing cell damage, polyphenols work a different way here. They're actually converted in the gut into those dietary compounds that help bind iron in the urine, keeping it from fueling bacterial growth.

Here are the top sources of polyphenols that may help prevent your next urinary tract infection: unsweetened cranberry juice, blueberries or blueberry juice, coffee (decaf is fine), black tea, and dark chocolate.

You can also try unsweetened yogurt, which nourishes your beneficial gut bacteria so that they can help process the foods you eat into more of those bacteria-busting compounds.
What not to eat? Glad you asked. Foods and beverages that lower your urinary pH are going to work against you. That includes a diet high in animal protein, phosphoric-acid containing beverages, such as sodas, and large doses of vitamin C, which you might get from a supplement.  
You'll also want to avoid unnecessary antibiotics. "It may take down a component of your immune system, making you more likely to get an infection down the line," Henderson says.
