However, if a banana is the only food you eat before several hours of work or study, you may become hungry again fairly quickly.
That’s because bananas contain mostly carbohydrates and relatively little protein or fat.
For Better Energy
Instead of eating a banana by itself, combine it with:
Oats
Cottage cheese
Greek yoghurt
Nut butter
Chia seeds
Mixed nuts
These foods help create a meal that digests more slowly and provides steadier energy.
Do Bananas Make You Sleepy?
One common myth is that bananas make people sleepy because they contain serotonin or tryptophan.
While bananas do contain small amounts of these compounds (or their precursors), the amounts found in a typical serving are not enough to make most people feel sleepy.
In fact, many athletes eat bananas before exercise because they provide easily digested carbohydrates that support physical activity.
If you personally feel relaxed after eating a banana, that’s perfectly normal—but it isn’t a universal effect.
