Banana for depression

Banana for immunity

Bananas are a powerhouse of nutrients. They contain vitamin B6, vitamin C, potassium, iron, fibre and magnesium. Intake of a banana ensures 25% of the recommended daily allowance (RDA) of vitamin B6. Vitamin B6 serves as an immunity booster and is essential for producing red blood cells and antibodies. It also helps in the metabolism of fats. It shields and safeguards against infectious diseases. An average sized banana makes up for 15% of the RDA of the strongest antioxidant, vitamin C.

Banana controls cholesterol levels

Banana has been blessed with a tremendous potential to lower the blood cholesterol. The cholesterol-lowering effect is due to the dietary fibre component in banana and this remains constant during its ripening, which serves best for the purpose. Bananas are a good source of dietary fibre which helps in controlling the LDL or bad cholesterol.

Banana for hangovers

Banana for blood pressure

Bananas are very rich in potassium which is important for maintaining normal blood pressure and heart function. Potassium also helps the body to maintain the normal fluid and electrolyte balance of cells. 350 mg of potassium can be obtained from a medium-sized banana. Scientists have also reported that the natural compounds in bananas act like anti-hypertensive drugs. Studies showed that people who consumed 2 bananas daily for a week recorded a 10% fall in blood pressure.

Banana for babies

Mothers can trust bananas as they are the best solid food for their infants. A mashed ripe banana is a very simple and healthy baby food. Bananas are digested and do not easily cause any allergic reactions in the stomach. They are a major part of the diet known as BRAT diet, recommended for children who are recovering from gastrointestinal problems, especially diarrhoea. Recent research shows that a higher consumption of bananas may protect children against wheezing.

Banana is good for kidneys

Bananas, being enriched with potassium, promote the overall functional efficiency of the kidneys. Normal intake of potassium in the diet ensures that there is no excretion of calcium in the urine and subsequently there is a lesser risk of developing kidney stones. Interestingly, women who consume at least 2.5 servings of fruits and vegetables per month were found to be at a 40% lesser risk of developing kidney cancer. Women who prefer eating bananas at least four to six times a week reduce the risk of developing the disease to almost 50% as compared to those who do not.

Banana for Alzheimer's disease

The researchers of the Cornell University found out that banana extracts prevent neurotoxicity.  Fruits such as apples, bananas, and oranges contain phenolic phytochemicals. These results showed that if these fruits are included in our daily diet with other fruits, they protect the neurons from stress-induced oxidative neurotoxicity. This may play a pivotal role in diminishing the risk of neurodegenerative disorders like the Alzheimer’s disease.

Banana for acidity

Bananas have been known for their antacid effect since very long. Such an effective antacid ability helps to protect against stomach ulcers and ulcer damage as well. A flavonoid, a plant product which is not useful for the plant but for humans, is present in banana, which is known as leucocyanidin. This substance helps in increasing the thickness of the inner membrane of the stomach, which is the sticky mucous membrane. As acidity is related to the sudden occurrence of heartburn, bananas are a potential treatment to get rid of it. Interestingly, in the recent studies, suppressed acid secretion was noticed by the simple mixture of banana and milk.

Banana regulates bowel movement

Banana fruit is rich in non-digestible fibres (like cellulose, alpha-glucans and hemicellulose). Such fibre helps in restoring normal bowel or the digestive activity, thus helping with both constipation and diarrhoea. It works by normalizing the colon’s ability to absorb large amounts of water for regular bowel movements. Bananas are useful due to their richness in pectin. Pectin is a good water-absorbent and this also gives them the ability to produce bulk.

Banana for a healthy gut

Bananas are an exceptionally rich source of a carbohydrate known as fructooligosaccharide. This compound provides nourishment to the friendly bacterium in the colon of the stomach. These beneficial bacteria excel in producing vitamins and digestive enzymes which improve the stomach’s ability to absorb nutrients and compounds, which in turn, safeguard us against unfriendly microbes. When fructooligosaccharides are fermented by such protective bacteria, not only the numbers of probiotic bacteria increase, but it also increases the body’s ability to absorb calcium, an important mineral for our bones.

Banana for a healthy heart

A decrease in potassium level in the body could lead to an increased risk of stroke. A recent clinical study conducted on 5600 people over 65 years of age revealed that those who had a low intake of potassium were at a 50% more risk of developing a stroke. The risk of stroke may be lowered by consuming potassium-rich foods like bananas, but more studies still need to be done to confirm this.

Furthermore, banana is a storehouse of antioxidants. These are active compounds that fight free radical damage and decrease oxidative stress on heart muscles. This helps in preventing cardiovascular diseases and keeping your heart functioning to the optimum.

Banana for instant energy

Sucrose, fructose and glucose, the three sugars present in the banana are combined with fibre to give instant energy to us. So, have a banana whenever you are tired to boost your energy. In fact, bananas are the first choice of athletes because of their high energy giving capability.

Symptoms like wheezing, coughing, itchy throat, runny nose and watery eyes are common with such an allergy.
  2. Migraine headaches
    Banana and alcohol is not a very wise combination because when they are consumed together, they can aggravate migraine headaches.

Like any eatable, banana also has its side effects; it all depends on us and how we consume it.
