Jul 13, 2018 · While some people like their bananas green, others love a mushy brown banana. But is there really a difference between the two? Surprisingly yes – and you could be picking the ripeness of the banana you eat based on your health.
You could eat unripened bananas or ripened bananas and get the benefits of either one. The only difference is that for Type 2 Diabetics and anyone trying to avoid excess sugar.

Green bananas are less sweet and contain less sugar than riper yellow bananas. They also have more resistant starch, which may benefit blood sugar management and your overall health.
Bananas are incredibly tasty and easy to eat. What’s more, they’re rich in many essential vitamins and minerals.
Bananas are typically harvested while they’re still green. This helps ensure they don’t get too ripe before you buy them.
That’s why you might see them in this color in the supermarket.
Besides being different in color, green and yellow bananas differ in several ways:
•Taste. Green bananas are less sweet. In fact, they can be a little bitter in taste.
•Texture. Green bananas are firmer than yellow bananas. Their texture has sometimes been described as waxy.
•Composition. Green bananas are higher in starches. As bananas ripen and turn yellow, the starches transform into sugars.
Unripe bananas contain mostly starch, which makes up 70–80% of their dry weight (1).
Much of that starch is resistant starch, which is not digested in the small intestine. For that reason, it’s often classified as dietary fiber.
However, bananas lose their starch as they ripen.
During ripening, the starch is converted into simple sugars (sucrose, glucose, and fructose). Interestingly, ripe bananas contain only 1% starch.
Green bananas are also a good source of pectin. This type of dietary fiber is found in fruits and helps them keep their structural form.
Pectin breaks down when a banana becomes overripe, which causes the fruit to become soft and mushy (2).
Green and yellow bananas are both good sources of many important nutrients.
Although the exact nutrient profile of green bananas is not available, they should contain the same micronutrients as when they are ripe.
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 DV
Green bananas are very filling, largely because of their high fiber content.
Fiber-rich foods provide bulk and can promote satiety, or fullness (6).
Both resistant starch and pectin — the types of fiber found in green bananas — have been linked to an increased feeling of fullness after meals (7, 8).
These types of fiber may also slow down the emptying of your stomach and lead you to eat less food (9, 10).
In turn, this may cause you to eat fewer calories. This could help with weight loss, if that’s your goal.
Summary
The nutrients in green bananas may also have a prebiotic effect.
Instead of being broken down in your intestine, resistant starch and pectin feed the friendly bacteria that reside in your gut.
The bacteria ferment these two types of fiber, producing butyrate and other beneficial short-chain fatty acids (11).
Short-chain fatty acids may help with various digestive complications (12, 13, 14).
In addition, some evidence suggests that they help protect against colon cancer, but more human studies are needed (15, 16).
Summary
Having high blood sugar levels is a major health concern.
If left untreated over time, it may lead to type 2 diabetes and raise the risk of other serious health problems.
Both the pectin and resistant starch in green bananas may help control blood sugar after meals (17, 18).
Unripe green bananas also rank low on the glycemic index, with a value of 30. Well-ripened bananas have a score of around 60 (19).
The glycemic index measures how quickly foods raise blood sugar levels after eating (20).
The scale runs from 0 to 100, and lower values are good for blood sugar control.
Green bananas are generally considered to be healthy. However, there have been some online reports of people experiencing discomfort after eating them.
This includes digestive symptoms like:
•bloating
•gas
•constipation
Additionally, you may want to be careful with green bananas if you’re allergic to latex.
Green bananas may provide some additional nutrients and benefits that yellow bananas do not.
They’re rich in resistant starch and pectin, which are filling, improve digestive health, and help lower blood sugar levels.
However, they are not as sweet as a ripe banana and the texture may not be as enjoyable if you like your bananas on the softer side.
Interestingly, the resistant starch and pectin gradually decrease as the banana ripens, so bananas that are yellow with a hint of green should still contain small amounts.
Jun 15, 2024 · Ripe bananas are a rich source of potassium and antioxidants, while unripe bananas boast higher levels of resistant starch, fiber, and certain vitamins. Ultimately, the choice between ripe and unripe bananas may come down to your personal preferences, dietary needs, and health goals.
Jul 30, 2019 · Underripe bananas are a great source of prebiotics for gut health and FODMAP friendly, while overripe ones contain the highest sugar and lowest fibre content but are rich in potassium, Vitamin B6, Vitamin C and Fibre, according to sports dietitian Ryan Pinto.

Oct 25, 2023 · Ripe vs. Overripe Bananas. The best stage of ripeness to eat bananas is the stage you enjoy the most, but there are also some nutritional differences that vary by ripeness. For example, green bananas (underripe) contain more resistant starch and fiber than riper bananas.
