Citrus fruit is also well-researched. The acidity of these fruits is considered to act beneficially on the digestive tract by lowering the pH and making it more acidic. It’s worth mentioning that, contrary to rumors, acidity is not a bad thing. It helps a balanced gut environment for beneficial bacteria in the gut.
Pineapple is a source of bromelain that proves to play a role in breaking down undigested food in the stomach, enhancing the overall removal of food remnants from the digestive tract (both stomach and gut).
Yellow citrus can also help lower the glycaemic load of starchy foods that reduce the impact of carbohydrates on blood sugar levels. Also, a flavonoid in citrus, called naringenin, seems to have antidiabetic activities. Other phytonutrients in citrus, including rutin, hesperidin, and nobiletin, help protect the stomach from gastric ulcers.
