Gallbladder disease, in which stones are found in the gallbladder, is the most common disorder of the biliary system.
Although in most cases it is asymptomatic, it still remains one of the most common ailments affecting emergency-room patients who complain of symptoms such as acute epigastric/right flank pain, nausea, and vomiting.
For these reasons, it is important to implement preventive habits in our lifestyles, specially food habits as they may both avert or significantly mitigate the course of the already present disease.
Banana is one such food that you can keep in your daily food chart to help with gallbladder stone prevention, and during gallstones conditions or even after removal.
Why Banana Good In Gallstones Conditions?
Since in about 90 – 95% of cases gallstones are made out of cholesterol, it is no wonder that diet may turn out to be crucial in this condition.
Indeed, multiple studies show that a healthily balanced diet that is plentiful in fruits and vegetables as well as low in red meat and high-fat products is inversely proportional to the risk of developing gallbladder disease. [1,2,5]
Moreover, in those with ongoing condition, it notably reduces the risk of acquiring gallstones that require surgery.
Similarly, other particular nutrients including fibre, magnesium and antioxidants confirmedly provide a protective effect. 
Because of such information, bananas have been examined more closely in relation to gallstone disease. Luckily for their fans, the fruits can be immensely beneficial when struggling with gallbladder stones.
First and foremost, bananas are extraordinarily rich in fibre, a known protective nutrient. [3,4] Besides, they contain magnesium, and numerous antioxidants including flavonoids and carotenoids.
The only thing one may be concerned about when eating bananas while having gallbladder stones is their sugar content.
Although its absorption in the gut is vastly buffered by the abundance of fibre, one banana still contains about 12 g or 0.42 oz of sugar.
Simultaneously, research shows that high consumption of simple sugars can drastically increase one’s cholesterol levels due to a promoted insulin response. 
It is estimated that intake of 40 g per day doubles the risk of symptomatic gallstones.
Because of the above reasons, it is not only perfectly healthy but also recommended to eat bananas for gallbladder stones conditions, or even prevention – just eat them reasonably as an addition to a healthy diet; one banana a day will suffice.
If you are wondering which type of banana is the best, go for the less ripe ones. Ripe bananas contain more simple sugars and therefore stimulate insulin more intensely.
At the same time, bananas are a perfect food to eat when having undergone cholecystectomy (gallbladder removal) or gallstone removal.
In both cases, a low-fat diet full of easily digestible carbohydrates and fibre is advised and may even decrease the risk of acquiring post-surgery symptoms like diarrhea, nausea, or bloating.
