Bananas contain fiber, potassium and antioxidants, all of which have been linked to various health benefits. According to research and a liver specialist, the fruit can be part of a diet that supports liver health, although overall eating habits remain the most important factor, reports Parade.
One in four Americans has MASLD
Around 25% of people in the United States are living with metabolic dysfunction associated steatotic liver disease, or MASLD, a condition previously known as nonalcoholic fatty liver disease.
Diet quality plays a major role
According to gastroenterologist and hepatologist Dr. Qin Rao, overall dietary habits play an important role in liver health and the risk of liver disease.
Fruits and vegetables are linked to lower risk
A 2024 analysis found that a higher intake of fruits and vegetables was associated with a lower risk of MASLD.

Research findings are not entirely consistent
A 2022 study found that participants with MASLD who consumed at least four servings of fruit per day had a higher BMI after six months than those who ate less fruit.
Fiber may benefit the liver
Dr. Rao explains that fiber can support liver health by improving blood sugar control, helping maintain a healthy weight and reducing fat accumulation in the liver.
Studies point to benefits of higher fiber intake
Research published in 2023 found an association between higher fiber consumption and a lower risk of MASLD.
The gut and liver are closely connected
Blood from the intestines flows directly to the liver, meaning that conditions in the gut can influence liver function and overall liver health.

Bananas may support beneficial gut bacteria
The fiber found in bananas can help nourish beneficial bacteria in the gut, which Dr. Rao says may indirectly benefit the liver.
Potassium may also play a role
Bananas are a well known source of potassium. According to Dr. Rao, some studies have linked higher potassium intake with a lower risk of fatty liver disease and liver scarring.
Antioxidants help protect the body's cells
Bananas contain antioxidants that help protect against oxidative stress, a process associated with inflammation and liver damage.
Natural sugar is different from added sugar
Although bananas contain natural sugars, Dr. Rao emphasizes that the fruit also provides fiber, vitamins and antioxidants that influence how sugar is absorbed by the body.
