ABSTRACT
Food industries add other inorganic material to the organic food in order to increase some properties. The vast majority of those ingested particles are eliminated mixed with faeces, but part of them touch the walls of the stomach or of the intestines and stay there long enough to be captured by the tissue and, eventually, negotiate it. The main difference between ingested and inhaled particles is size. The pollution of the flour could have come from various, different sources: from environmental situations where the cereal had grown, from polluted soil or from processing residues, often caused by mechanical metal organs which are worn and whose residues inevitably end up in the flour. Animal physiology is very similar, not too rarely actually identical, to that of humans. The inevitable consequence is that, when those animals become our food, they introduce those pollutants into our body.
