Don't you mean Mental or Emotional Trauma? Being scared doesn't make it physical.
And yea, I kinda have to agree with Ilikeanime, but with the explanation being gourmet cells, it only makes me crave a proper explanation of what Gourmet Cells are and what can they fully do, as the author doesn't do enough to go over them, despite Gourmet Cells being the main power source the characters use. Guess the monkey dance or that shitty Food Honor is more important?
