Banana
One of the most widely eaten fruits in the world — sweet, portable, and rich in potassium.
What Bananas Provide
Bananas are best known for their potassium content and easy-to-digest carbohydrates. They also provide vitamin B6, vitamin C, magnesium, and fibre. The carbohydrate content is a mix of glucose, fructose, and starch — with the starch converting to sugar as the banana ripens (which is why greener bananas taste less sweet).
Nutrition Highlights
Potassium
One medium banana provides around 422 mg of potassium — about 9% of the daily value. Potassium is involved in muscle function, nerve signalling, and blood pressure regulation.
Vitamin B6
Bananas are one of the best natural sources of vitamin B6, providing about 25% of the daily value per medium banana. Vitamin B6 supports brain development, immune function, and the breakdown of proteins.
Fibre
Around 3 g of fibre per banana — mostly pectin, which can help with digestion and may support healthy blood sugar levels. Greener bananas have more resistant starch, which acts as a prebiotic.
Carbohydrates
About 27 g of carbs per medium banana. This makes bananas a practical pre-workout or post-workout snack, providing quick energy and small amounts of electrolytes.
How to Include Bananas in a Balanced Diet
- Sliced on oatmeal or yogurt for breakfast.
- As a pre-workout snack 30–60 minutes before training.
- Blended into smoothies with spinach and protein powder.
- Frozen and blended into a dairy-free 'nice cream'.
- Sliced with a spoon of peanut butter as a balanced snack.
Who Might Want to Watch Portions
Because bananas are relatively high in carbohydrates and natural sugars, people with diabetes or those following a very low-carb diet may want to be mindful of portions. Pairing a banana with protein or fat (yogurt, nuts, nut butter) slows the rise in blood sugar.
