PROTEIN QUALITY
Are bananas a good source of protein?
No. Bananas contain some protein, but the amount is too small for them to function as a meaningful protein source.
A medium banana provides only about 1.3 g of protein.
Bananas can still fit well in a high-protein meal when paired with foods such as yogurt, milk, cottage cheese, peanut butter or protein powder.
PUT IT IN CONTEXT
How many bananas would provide 20–30 g of protein?
~25 g protein
about 19–20 medium bananas~25 g protein
~30 g protein
about 23–24 medium bananas~30 g protein
Those numbers are intentionally impractical: they show why bananas should not be treated as a primary protein food.
