Dr. Surab Sethi, a gastroenterologist from California and a Harvard graduate, warned that one of the most commonly consumed fruits may be harmful to gastrointestinal health, the Mirror reported. 

In a video that has already been viewed more than 1.5 million times on Instagram, he ranks fruits from most beneficial to worst for the gut. According to him, blueberries are the best choice because they are rich in anthocyanins and soluble fiber, which nourish beneficial bacteria and reduce inflammation.

Kiwis, pomegranates, and apples also rank high on the list. Pears are also beneficial because they contain a lot of fiber and create a feeling of fullness, although in larger quantities they can cause gas.

Lower on the list are citrus fruits, melons, and grapes, the latter of which can even cause bloating and sharp spikes in blood sugar due to their high natural sugar content and low fiber content. 

According to Dr. Seti, the worst fruit for the intestines is overripe bananas. The reason is that their starch turns into simple sugars, which quickly raise blood sugar levels and provide almost no "fuel" for beneficial bacteria. This can lead to bloating and discomfort. The expert recommends eating slightly green bananas, as they contain resistant starch, which is fermented by gut microbes and forms short-chain fatty acids that are beneficial to the colon.

The UK's National Health Service (NHS) reminds us that it is important to consume at least five portions of fruit and vegetables a day, which can be fresh, frozen, dried, or canned. Regular consumption reduces the risk of heart disease, stroke, and certain types of cancer. | BGNES
