Overall, bananas contain more calories, but hold very little proteins and no fat, each banana has about 89 calories and, while orange contains 47 calories and almost no fat.
The amount of food energy in each banana is 371 KJ per 100g, while in each orange is 197 KJ per 100g.

Depending on growing conditions the acidity of fruits can change.On average, oranges have a pH of between 3 and 4.
The acidity of oranges depends on the region in which they are grown ․ The acidity of foods can also be portrayed by the potential renal acid load (PRAL), which shows the acid production of the food, inside the organism. Bananas have a pH of about 5, making them a mildly acidic food, however, orange's acidity is higher .
Bananas and oranges are both used in different diets. They both are middle calories fruits but hold very little proteins and no fat. Although eating bananas can’t directly lead to weight loss, in this case, some of the components of these fruits can help reduce bloating and replace processed sugars.

In general, like every citrus fruit, oranges may have a role in preventing certain cancers. Oranges contain both colored and colorless carotenes such as phytoene and phytofluene, as well as different groups of xanthophylls, such as monohydroxy carotenoids. Carotenoids of citrus fruits have been associated with a decreased risk of cancers, specifically in the digestive and upper respiratory tract. 
Some studies suggest that the role of bananas in the fight against cancer has not been established, and some studies emphasize the positive effects of bananas. Nevertheless a Swedish study found that women who ate four to six bananas a week cut in half their risk of developing kidney cancer.
Bananas may help prevent kidney cancer because of their high levels of antioxidant phenolic compounds .
