Както се посочва в самото проучване, не само желязото, използвано в хранителните добавки, може да е опасно. Желязото, използвано в хранителните продукти, е също толкова опасно и може да има още по-голямо въздействие, тъй като почти всички хора ежедневно консумират храни от търговската мрежа, докато много по-малко хора консумират добавки с желязо. Фактът, че дори много ниски количества желязо в хранителните добавки са канцерогенни, категорично потвърждава твърденията на Peat, че освен малките деца, повечето други хора трябва да стоят настрана от добавките с желязо. За съжаление, поради повсеместното обогатяване с желязо в търговската преработка на храни, става почти невъзможно да се избегне допълнителното желязо, без да се стигне до орторексия. По този начин използването на аспирин или витамин Е няколко пъти седмично може да бъде по-практичен подход за намаляване на претоварването с желязо.

“…The scientists — led by Nathalie Scheers, an assistant professor at the Chalmers University of Technology — explain that their research was prompted by older studies that showed that two compounds, called ferric citrate and ferric EDTA, promote tumors in mice. But, these previous studies did not reveal “whether all forms of ‘bioavailable’ iron exacerbate gut cancer cells,” or whether different forms of iron display the same mechanism. So, in the new study, Scheers and colleagues examined the effect of these two compounds on the growth of human colorectal cancer cells. Additionally, they tested another widely available iron compound called ferrous sulfate. In their experiment, the researchers used levels of the compounds that might realistically be found in the gastrointestinal tract after taking the supplement. To their knowledge, Scheers and colleagues are the first to study the effect of these compounds on human cells. The researchers published their findings in the journal Oncotarget.”

“…The study revealed that even in low amounts, both ferric citrate and ferric EDTA raised cellular levels of a cancer biomarker called amphiregulin and its receptor. By contrast, ferrous sulfate had no such effect on the cells. “[S]pecific iron compounds affect cell signaling differently, and some may increase the risk of colon cancer advancement in an amphiregulin-dependent fashion,” the authors write. Scheers comments on the findings, saying, “We can conclude that ferric citrate and ferric EDTA might be carcinogenicas they both increase the formation of amphiregulin, a known cancer marker most often associated with long-term cancer with poor prognosis.”
