Are there any foods that don't do anything to your body?!
Answers: Like foods that aren't healthy or foods that are not bad for you they just don't do anything except fill you up a little bit.
No matter what, food has an impact in your body. Even celery and lettuce, which are primarily waterand contain very little beyond that, cause your body to burn more calories than you consume. there are plenty of empty calories out there that provide just a "filling up" effect without providing actual nutritional benefit.
No matter what you eat, it'll do something to your body, it just depends on the size of the food, like a little bit of carrots should do good, they definitely won't make a huge difference.
I agree that anything you ingest will have some sort of effect. Iceberg lettuce probably has the least amount of nutrients while still not being unhealthy for you.
