  • Carbohydrates: 23g
  • Dietary fibre: 4.62g

  • Niacin: 0.665mg
  • Pantothenic acid: 0.334mg
  • Pyridoxine: 0.367mg

Note: This is the nutritional value for 100 grams of banana. It is not the recommended amount for consumption. One to two medium-size bananas per day (each banana is approx. 30 grams) is considered a moderate intake for most healthy people. 

Does Regularly Eating Banana Increase Weight?

One of the reasons people believe that eating bananas cause weight gain is because they contain sugar. The sugar in bananas is naturally occurring, meaning it won’t be readily absorbed. As a result, it does not cause blood sugar spikes or weight gain, unlike added sugars. This is keeping in mind a moderate intake of the fruit.

Bananas, on their own, are calorie-dense. You need to be concerned about weight gain if you consume many bananas daily. However, this goes for any food. If you consume food in large quantities, you’re more likely to consume more calories than you burn and possibly gain weight from that. Consuming one banana a day is an excellent addition to a healthy weight management plan. 

Are Bananas Good for Weight Loss?

Bananas can help you lose weight, making them one of the best weight loss-friendly foods. Greener, less ripe bananas have a higher level of starch — particularly resistant starch. The gut-healthy prebiotic resistant starch is digested more slowly and helps you feel fuller. Therefore, it makes you eat less in your next meal, ultimately supporting your weight loss journey. 

In addition, a study shows that fibre-like properties of resistant starch increase the thermic effect of food. The thermic effect of food refers to the energy required for the digestion of food. As a result, an increased thermic rate boosts total calorie or energy expenditure. Therefore, high-calorie use tends to promote weight loss. The resistant starch in bananas is promoted as a “weight loss wonder food” due to its ability to reduce fat storage. The resistant starch has a positive impact on insulin resistance. Meaning it improves insulin sensitivity, which helps the body process glucose more efficiently, reducing weight. 

Bananas are sweet enough to be a healthy dessert. You can add them to your diet as a suitable replacement for fattening sweets and desserts. Eating a banana with a protein source like almonds and peanut butter keeps your sugar cravings satiated and prevents overeating.  , Furthermore, bananas are a more nutrient-dense option than calorie-dense snacks. 

The Fibre in Bananas and Weight Loss

A study shows that dietary fibre intake paired with a calorie-restricted diet promotes weight loss For example, a medium-sized banana contains about 3 grams of fibre. The healthy fibre dose keeps you full and stabilises blood sugar making banana an excellent food for weight loss. Moreover, eating a high fibre level may cut the risk of gaining weight by up to 30%. 

The fibre in bananas stays in your gastrointestinal tract for more extended periods because it’s difficult for your body to break them down. As a result, it reduces appetite and increases the feeling of fullness post eating bananas, leading to weight loss by curbing overeating. 

Other Health Benefits of Banana

1. Memory Preservation and Mood Enhancement

According to research, bananas include tryptophan, an amino acid that enhances a person’s ability to memorise and remember things while also regulating mood. 

2. Immunity Booster

Bananas contain several nutrients, including antioxidants that help in improving overall health. In addition, it includes a good amount of vitamin B6, vitamin C, magnesium, and vitamin A that benefit immune functions. 

3. A Fibre-Rich Feast

It’s no secret that getting enough fibre in your diet is beneficial. Soluble fibre makes up most of a banana’s fibre. As a result, it can aid in the control of cholesterol and blood pressure.

4. Aids Digestive Health

Banana provides several health benefits, including improved digestion, because it contains a high level of dietary fibre. Prebiotic-resistant starch is a form of fibre found in unripe bananas. Research says prebiotics make it through your large intestine, where they feed and nourish the good bacteria in your gut. In addition, the fruit increases bloat-fighting bacteria in the stomach, and its high potassium content can help diminish the retention of fluids. 

5. Perfect Food for Toddlers

Bananas are  an excellent solid meal for newborns to start.  mashed bananas can be a highly nutritious and esaily digestable infant food. 

6. Restores Regular Bowel Activity

Bananas are high in non-digestible fibres like cellulose, hemicellulose, and alpha-glucans. It aids the restoration of normal bowel function and relieves from both constipation and diarrhoea. It generally depends on how ripe the banana is. Further, it restores colon function by allowing it to absorb a considerable amount of water, allowing for regular bowel movements. They have a bulk-producing potential because of their high pectin content and water-absorbent.

7. Bananas Help with Iron Deficiency

A study shows that green, raw bananas (plantain-0.75mg/100g according to USDA) contain more iron than ripe bananas. In addition, cooked bananas have a higher iron level (0.53mg/100g) than raw bananas (0.33mg/100g). The banana is a possible carrier for iron fortification because it is one of the most commonly produced fruits—iron and vitamin B6 aid in preventing anaemia by making enough red blood cells.
