While cranberries aren't the most popular fruit in the produce section of the market, this tart berry packs plenty of nutritional power in a tiny package. Cranberries contain fiber and proanthocyanidins (PACs), a chemical compound that gives cranberries their bright red color. PACs are also associated with certain health benefits. For instance, eating cranberries may improve your body's ability to help fight certain infections and inflammation.

Including cranberries in your diet is a tasty way to get more fruit and boost nutrient intake. The 2020-2025 US Dietary Guidelines for Americans suggest that you consume two cups of fruit per day. The guidelines clearly recommend getting more whole fruit as often as possible. Eating whole or dried cranberries can help you reach that goal.

Health Benefits of Cranberries

There is substantial research investigating the potential health benefits of cranberries. But some of the research involves cranberry extract or cranberry juice, so it is unclear whether or not consuming whole cranberries can provide these benefits and if so, in what amount. So far, this is what we know about the potential impact of including cranberries or cranberry products in your diet.

Helps Increase Antioxidant Intake

Research on both American and European whole cranberries has shown the fruit is an important source of antioxidants. These antioxidant compounds can help prevent or reduce oxidative damage to your body's cells. Oxidative damage can occur when you are exposed to free radicals from sources such as cigarette smoke or air pollution.

While research on antixodants is ongoing, health experts believe that oxidative damage may play a role in a diseases such as cancer, cardiovascular disease, or diabetes. Increasing your intake of anti-oxidant rich foods may help you to lower your risk for these conditions.

May Help Prevent UTIs

UTIs or urinary tract infections are one of the most common bacterial infections in women. According to the U.S. Department of Health and Human Services, more than half of women will have at least one UTI at some point in their lives. The painful condition can cause symptoms such as lower abdominal pain and a burning sensation when you urinate.

Cranberries have long been considered a prevention method for UTIs. There isn't conclusive research to help us know for sure if the fruit can provide this benefit, but there is some evidence to support its use.

The PACs in cranberries help prevent bacteria from sticking to cell walls, and this helps the body fight infections. While there isn't significant research linking whole cranberries to infection prevention, plenty of research supports the use of cranberry juice and cranberry supplements to help reduce the risk of recurrent urinary tract infections (UTIs) in women.

May Support Gut Health

Emerging research shows that PACs in cranberries help maintain healthy gut bacteria, which can help the body manage inflammation, which is linked to certain chronic diseases such as heart disease and type 2 diabetes. Cranberries contain fiber which can help improve digestion and may help keep good bacteria in your gut.

Some evidence shows that the fiber and other healthful parts of cranberries have prebiotic effects on gut bacteria that may be important for helping the body manage inflammation in the intestinal tract. Fruit intake can increase the number and variety of gut bacteria, which is shown to lower your risk of type 2 diabetes.

May Help Prevent Cavities

Some studies have shown an association between cranberry extracts and better dental health. Specifically, research suggests that the polyphenols in the fruit may have the potential to help prevent dental caries, also known as tooth decay or cavities.

For this reason, the American Dental Association includes cranberries in their list of foods which might be able to prevent dental disease. They also include foods such as dairy products, apples, and tea. But the organization also notes that more research is needed to fully understand the link between these foods and better dental health.
