Bananas are often known as the “energy fruit,” a quick fix before workouts or a handy breakfast snack. But according to Dr Tarang Krishna, their power goes far beyond energy. Eating just two bananas a day can actually protect the body against some life-threatening diseases, including stomach ulcers and even stomach cancer. It’s a simple fruit, often taken for granted, yet it carries a remarkable shield within.
A natural guard for the stomach
Dr Krishna highlights that bananas have natural compounds that strengthen the stomach’s protective lining. This lining acts as a barrier against acid and harmful bacteria. One such bacterium, Helicobacter pylori (H. pylori), is known to cause painful ulcers and, in the long run, can lead to stomach cancer. Regular banana intake helps reduce the activity of this bacterium, giving the gut a natural layer of defence.
The role of flavonoids and antioxidants
Bananas are rich in flavonoids and antioxidants, which work like tiny soldiers inside the body. These compounds fight inflammation and prevent oxidative damage, one of the key triggers of many chronic diseases. By neutralising harmful free radicals, bananas not only reduce gut irritation but also keep the internal tissues healthy and strong.

How bananas build a shield inside the body
Dr Krishna explains that bananas help stimulate the production of extra mucus in the stomach. This mucus acts like a soft, protective cushion that prevents acid from directly touching the stomach wall. It’s this very mechanism that allows bananas to calm ulcers and prevent them from worsening. Think of it as creating a safety cover inside the digestive system, all through a simple, natural food.
More than protection
Apart from guarding the gut, bananas are also excellent for maintaining smooth digestion. The fruit contains prebiotic fibres that help good bacteria flourish inside the intestines. This not only improves digestion but also strengthens overall immunity. The natural sugars in bananas release steady energy without causing sudden spikes in blood sugar, making it one of the most balanced fruits nature offers.
The simplest way to care for health
A banana might seem ordinary, but its health benefits are anything but. It’s inexpensive, easily available, and suits every age group. Whether blended into smoothies or eaten plain, it silently supports the body’s natural defence system, proving that sometimes, the most powerful health protectors come wrapped in simplicity.Disclaimer: This article is based on insights shared by medical experts and available scientific evidence.
