While ripe, yellow bananas are a popular and convenient snack, their less celebrated green counterparts offer a unique set of nutritional benefits that can be particularly advantageous for weight loss and overall health. Often overlooked, green bananas boast a distinct nutritional profile that sets them apart from their sweeter, riper versions. This article delves into the science-backed reasons why incorporating green bananas into your diet could be a strategic move toward achieving your weight management goals, improving your metabolism, and enhancing your well-being.
Introduction: Beyond the Yellow Peel
Recently, a nutritionist shared a revelation: green bananas possess unique nutritional advantages absent in ripe bananas. While yellow bananas are beloved for their sweetness, green bananas offer a distinct suite of health benefits. Green bananas are typically harvested while they’re still green to ensure they don’t get too ripe before you buy them. That’s why you might see them in this color in the supermarket.
The Nutritional Powerhouse of Green Bananas
Both green and yellow bananas are nutritious, but the composition of carbs in a banana depends on how ripe it is. A yellow medium-size banana (118 grams) contains the following vitamins and minerals, and an unripe banana will likely have more fiber because of its high resistant starch content (5): Fiber: 3 grams Potassium: 9% of the daily value (DV) Vitamin B6: 25% of the DVVitamin C: 11% of the DVMagnesium: 7% of the DVCopper: 10% of the DVManganese: 14% of the DV. In addition, it has 105 calories. Of those, more than 90% come from carbs. Additionally, bananas are very low in fat and protein.
Key Benefits of Green Bananas for Weight Loss
1. Rich in Resistant Starch: A Game-Changer for Weight Management
Green bananas are rich in resistant starch, a type of carbohydrate that resists digestion in the small intestine and acts similarly to dietary fiber. Instead, it reaches the large intestine where it becomes a valuable food source for beneficial gut bacteria. This process not only promotes a healthier gut microbiome but also helps in increasing the feeling of fullness, which can be a game-changer in weight management.
How Resistant Starch Works
- Supports Digestive Health: Resistant starches act as a prebiotic, feeding beneficial gut bacteria and promoting the production of short-chain fatty acids like butyrate, which supports colon health.
- Helps Regulate Blood Sugar: By slowing digestion, resistant starch helps moderate blood sugar levels, reducing post-meal blood sugar spikes.
- Increases Fat Oxidation: The resistant starch in green bananas increases fat oxidation, meaning the body's ability to burn fat for energy. This metabolic boost can contribute to weight loss by utilising stored fat more efficiently, especially when combined with regular physical activity.
- Promotes Satiety: Some research has shown resistant starch helps increase feelings of satiety.
2. Pectin Power: Enhancing Fullness and Appetite Control
Green bananas are bursting with pectin, a kind of dietary fiber that enhances feelings of fullness. What that means? It can potentially help with appetite control and weight management. And similar to resistant starch, pectin may help stabilize blood sugar levels after meals. Pectin breaks down when a banana becomes overripe, which causes the fruit to become soft and mushy.

3. Lower Glycemic Index: Stabilizing Blood Sugar Levels
The glycemic index (GI) measures how quickly a food raises blood sugar levels. Green bananas have a low GI of around 30, making them a healthy choice for those monitoring their blood sugar. Meanwhile, ripe bananas have a GI of approximately 60. Low-GI foods like bananas may also help you feel full and keep blood sugar levels stable, which may lead to weight loss over time.
Green bananas are lower on the glycemic index scale than ripe bananas with a value of 30 compared to 51, compared to overripe bananas that are between 52 - 70. However, regular bananas can still be just fine to eat as part of a healthy diet, especially when you consider the glycemic load for individual bananas. A banana is right in the middle on the glycemic load scale, but it depends on the portion size. A small banana is around 11, closer to the low end of the scale. A very large banana can be closer to the high end, falling around 20.
4. Energy Boost Without the Sugar Spike
Unlike ripe bananas which are high in sugars, green bananas provide a more sustained release of energy due to their lower sugar content. The levels of fructose, glucose and total sugar show a large increase going from unripe to ripe bananas. This can be particularly beneficial for those looking to stabilise blood sugar levels and avoid the energy crashes associated with high-sugar foods. A steady energy supply can support an active lifestyle and enhance the effectiveness of workouts, further aiding in weight loss.
5. Metabolism Kickstart
The resistant starch in green bananas increases fat oxidation, meaning the body's ability to burn fat for energy. This metabolic boost can contribute to weight loss by utilising stored fat more efficiently, especially when combined with regular physical activity.
6. Nutrient Powerhouse
Green bananas are not only a good source of resistant starch but also pack a nutritional punch with essential vitamins and minerals, including vitamin C, potassium, and vitamin B6. These nutrients play crucial roles in maintaining overall health and can support the body's metabolic processes.

Additional Health Benefits of Green Bananas
Beyond weight loss, green bananas offer a spectrum of health benefits:
- Improves Digestive Health: Green bananas are loaded with resistant starch and dietary fibre, which act as prebiotics, feeding beneficial gut bacteria. This helps promote a healthy gut environment, supports better digestion, and reduces bloating and constipation.
- Regulates Blood Sugar Levels: Due to their low sugar content and high resistant starch, green bananas help slow down glucose absorption and prevent blood sugar spikes. This makes them an excellent option for diabetics or those at risk of insulin resistance.
- Boosts Heart Health: The high potassium content in green bananas helps regulate blood pressure by relaxing blood vessels and improving circulation. Their fibre also helps lower bad cholesterol (LDL), reducing the risk of heart disease and stroke. Additionally, their anti-inflammatory properties support overall cardiovascular health.
- Enhances Gut Health & Prevents Constipation: Green bananas contain pectin and resistant starch, both of which help promote a healthy gut lining. These compounds prevent constipation by improving stool consistency and making bowel movements easier. They also reduce symptoms of diarrhoea by absorbing excess water in the intestines.
- Improves Nutrient Absorption: The prebiotic properties of green bananas enhance the absorption of essential nutrients, particularly calcium and magnesium, which are vital for bone health. Consuming green bananas can be beneficial for stronger bones and reducing the risk of osteoporosis as you age.
- Supports a Healthy Metabolism: The resistant starch in green bananas promotes better fat oxidation, helping the body burn fat more efficiently. This supports a healthy metabolism and better energy production, which is beneficial for those trying to maintain an active lifestyle or lose weight.
- Prevents Stomach Ulcers: Green bananas contain natural compounds that strengthen the stomach lining, reducing acidity and the risk of developing ulcers. They also stimulate mucus production in the stomach, which acts as a protective barrier against acid damage.
- Enhances Mood and Brain Function: Green bananas are a good source of vitamin B6, which helps produce serotonin and dopamine which are neurotransmitters responsible for mood regulation. This means that adding green bananas to your diet can help reduce stress, anxiety, and depression while improving cognitive function.
- Strengthens the Immune System: Rich in vitamin C, antioxidants, and fibre, green bananas help strengthen immunity by supporting gut health and reducing inflammation. The prebiotic effect of resistant starch enhances the body's natural defence system, making it easier to fight infections and illnesses.
Incorporating Green Bananas into Your Diet
You may be wondering how to include green bananas into your daily diet, but incorporating them into your diet doesn't have to be a chore. They can be enjoyed in various ways, from blending them into smoothies to incorporating them into savoury dishes. Experimenting with different recipes can allow you to reap the benefits of green bananas while adding variety to your meals.
