Bananas: Health Benefits Of Bananas To Human Body
Bananas are among the fruits that has many nutritious values.
Bananas are among the world’s most popular fruits.
Native to Southeast Asia, they are now grown in many warm parts of the world.
Bananas vary in color, size and shape.
The most common type is the Cavendish, which is a type of dessert banana. Green when unripe, it yellows as it matures.
Bananas contain a fair amount of fiber, as well as several antioxidants.
Contents of Bananas by percentages are:
Potassium: 9% of the RDI
Vitamin B6: 33% of the RDI
Vitamin C: 11% of the RDI
Magnesium: 8% of the RDI
Copper: 10% of the RDI
Manganese: 14% of the RDI
Net carbs: 24 grams
Fiber: 3.1 grams
Protein: 1.3 grams
Fat: 0.4 grams.
Each banana has only about 105 calories and consists almost exclusively of water and carbs. Bananas hold very little protein and almost no fat.
The carbs in green, unripe bananas consist mostly of starch and resistant starch, but as the banana ripens, the starch turns into sugar (glucose, fructose and sucrose).
They contain several essential nutrients and provide benefits for digestion, heart health and weight loss.
Aside from being very nutritious, they are also a highly convenient snack food.
Ever wondered what goodness is in a banana? Other than being rich in vitamin B6, bananas are a good source of vitamin C, dietary fibre and manganese. Bananas are also fat-free, cholesterol-free and virtually sodium-free. So what do these mean for your health?
Health benefits of bananas
1. Best sources of vitamin B6
Vitamin B6 from bananas is easily absorbed by your body and a medium-sized banana can provide about a quarter of your daily vitamin B6 needs.
Vitamin B6 helps your body:
produce red blood cells,
metabolise carbohydrates and fats, turning them into energy,
metabolise amino acids,
remove unwanted chemicals from your liver and kidneys, and
maintain a healthy nervous system.
Vitamin B6 is also good for pregnant women as it helps meet their baby’s development needs.
2. Moderation of blood sugar levels
Bananas are rich in pectin, a type of fiber that gives the flesh its spongy structural form.
Unripe bananas contain resistant starch, which acts like soluble fiber and escapes digestion.
Both pectin and resistant starch may moderate blood sugar levels after meals and reduce appetite by slowing the emptying of your stomach.
Furthermore, bananas also rank low to medium on the glycemic index (GI), which is a measure — from 0–100 — of how quickly foods increase blood sugar levels.
The GI value of unripe bananas is about 30, while ripe bananas rank at about 60.
This means that bananas should not cause major spikes in blood sugar levels in healthy individuals.
However, this may not apply to people with type 2 diabetes, who should probably avoid eating a lot of well-ripened bananas — and monitor their blood sugar carefully if they do.
3. Reduces the risk of developing Cancer
Laboratory investigations have suggested that lectin, a protein that occurs in bananas, may help prevent leukemia cells from growing.
Lectin acts as an antioxidant. Antioxidants help the body remove molecules known as free radicals. If too many free radicals build up, cell damage can occur, potentially leading to cancer.
In 2004, researchers noted that children who consumed bananas, orange juice, or both appeared to have a lower risk of developing leukemia.
The study authors suggested that this could be due to the vitamin C content, as this, too, has antioxidant properties.
4. Aid in digestion and reduce gastrointestinal problems.
A medium banana will provide about 10-12% of your daily fibre needs. Singapore’s Health Promotion Board recommends a daily dietary fibre intake of 20g for women and 26g for men.
Soluble and insoluble fibres play an important role in your health. Soluble fibre helps your body control your blood sugar level and get rid of fatty substances such as cholesterol. Insoluble fibre adds weight and softness to stools, making it easier for you to have regular bowel movements. This helps to keep your gut healthy and safe from harmful bacteria.
Bananas, especially newly-ripened ones, contain starch that does not digest (resistant starch) in your small intestine and is able to pass into the large intestine. Such bananas help you manage your weight better as you stay full for longer.
That said, bananas can help you beat gastrointestinal issues such as:
Constipation
Stomach ulcers
Heartburn.
5. Help to increase heart health
Potassium is a mineral that is essential for heart health — especially blood pressure control.
Despite its importance, few people get enough potassium in their diet.
Bananas are a great dietary source of potassium. One medium-sized banana (118 grams) contains 9% of the RDI.
A potassium-rich diet can help lower blood pressure, and people who eat plenty of potassium have up to a 27% lower risk of heart disease.
Furthermore, bananas contain a decent amount of magnesium, which is also important for heart health.
6. Powerhouse of Nutrients
Banana is a heavyweight when it comes to nutrition. It is loaded with essential vitamins and minerals such as potassium, calcium, manganese, magnesium, iron, folate, niacin, riboflavin, and B6. These all contribute to the proper functioning of the body and keeping you healthy.
7. Blood Pressure
It is a known fact that salt is the culprit when it comes to high blood pressure. Bananas have low salt content and high potassium content, and these properties contribute to making it an ideal for those undergoing this condition. But make sure you consult your nutritionist or doctor before you add it to your diet.
