The sentence “Did you know that eating bananas increases …” is incomplete in English, just like in Swedish.
It literally translates to:
“Did you know that eating bananas increases …”
But it doesn’t say what is being increased, so the meaning is unfinished.
If this came from a viral post, it’s probably trying to claim something like:
- energy
- potassium levels
- serotonin / mood
- weight gain
- digestion
If you share the rest of the sentence, I can translate it fully and also explain whether the claim is accurate or exaggerated.
