How can something have no calories? What does the body do with this calorie free food?
In: Biology
I’m not sure any food has actually 0 calories. A lot of vegetables like celery and arugula have very low <10 calories per cup. Despite the low calorie content, the body still has to break down a cup of arugula the same way it would a higher calorie food. It has to burn calories to extract the vitamins and minerals, digest, and pass it through the body. Even though the net calorie gain of eating a cup of arugula might be close to zero the body will still gain vitamin k, folate, etc
