No matter how much banana a person consumes, the probability of gaining weight and becoming obese is comparatively low.

We usually don’t get enough fibers through our daily diets. Fiber is of utmost importance for food to travel properly in the digestive tract. Since bananas are a high source of dietary fibers, it improves bowel movements to a great extent.

Consuming a few bananas is much better than taking laxatives to cure constipation. Bananas are also rich in FOS (fructo-oligosaccharides), this feeds the helpful bacteria which lives in our digestive tracts. This bacteria is known to absorb all the nutrients efficiently.

Cures heartburn

Bananas are great for curing heartburns as they relieve pain by enhancing the protective mucucs layer and balancing the stomach’s PH. The fiber content present in bananas also makes the food move to the digestive tract much faster, thus preventing an acid reflux.

Cures Ulcers

Consuming bananas regularly can also help to protect the stomach against ulcers. Continuously eating banana for a long period of time thickens the mucus barriers inside the stomach. This instead prevents damage from hydrochloric acid. Bananas also contains protease inhibitors which helps to reduce bacteria that causes stomach ulcers. Studies have shown that maximum number of people with healthy digestion regularly consumed banana.

Creating haemoglobin

Since bananas are a good source of vitamin B6, it creates abundant amount of haemoglobin for healthy blood supply in the body. Vitamin B6 is also involved in producing antibodies, breaking down and synthesizing amino acids, maintaining blood sugar levels, etc. These help in creating a strong immune response in the body. Bananas can certainly be a great substitute of Vitamin pills.

Skin conditions

Beauty has become very important in today’s world. We all want to achieve flawless and healthy skin, thankfully bananas can help to achieve this. Banana peels are very helpful in treating skin conditions such as acne and psoriasis. Rubbing the banana peel on the affected area helps release a lot of fatty acids from the peel which helps to relieve skin conditions and also moisturises the skin from within. Banana peels have also been helpful in removing warts since ages.

Reduces stress

Bananas contain amino acid tryptophan which the body converts into serotonin right after consumption. Serotonin helps to regulate sleep patterns, reduces stress, improves mood and increases happiness levels. Banana is not the highest source of serotonin but it helps to improve your mood to a great extent. This is the reason why we observe people snacking on a banana while feeling too stressed out during work.
