That looks like one of those click-bait posts that cuts off the claim. 😄
There isn’t one single thing bananas “increase” dramatically, but here are the common claims people usually mean—and what’s actually true:
- Energy 🍌 – Somewhat true. Bananas have carbs and natural sugars, so they can give a quick energy boost.
- Potassium levels – True, but not extreme. Bananas contain potassium, though foods like potatoes, beans, and spinach have as much or more.
- Mood / happiness – Overstated. They contain vitamin B6 and tryptophan, which help normal brain function, but they don’t magically boost serotonin.
- Weight gain – Mostly false. A medium banana is ~105 calories; weight gain depends on total diet, not bananas alone.
- Digestion / gut health – Somewhat true. They have fiber and resistant starch (especially when less ripe), which can help digestion.
If you want, tell me what the post claimed it increases, and I can tell you whether that specific claim is true, exaggerated, or flat-out false.
