Green bananas are packed with fibre, pre-biotics, and probiotics, all of which help with digestion. For people with digestive conditions like irritable bowel syndrome, eating foods that aid digestion may be particularly important. In terms of taste, green bananas are a little less sweet than their yellow counterpart. Regarding texture, they have been described as a little waxy whilst composition wise, green bananas are higher in starch. Green bananas contain a high amount of resistant starch and pectin, which have been linked to several health benefits. As bananas ripen, most of the starches are turned into sugar.
