New research on a sialic acid sugar N-glycolylneuraminic acid (Neu5Gc) indicates that we should modify our diets to avoid cancer and systemic inflammation. Earlier research found high levels of Neu5Gc in cancer tissue. High sensitivity LC mass spectrometry recently made measurements of this sugar in particular organs possible.
Human sialic acid (Neu5Ac) differs from Neu5Gc by only one oxygen atom, and our bodies fail to recognize it as alien. When we consume it, it becomes part of our cell membranes and then triggers an immune response and inflammation. It accumulates especially in cells lining the intestines and blood vessels, as well as in breasts, ovaries, uterus, the prostate and our pancreas. If we happen to consume the toxic varieties of E. Coli, these molecules act as toxin binding sites.
Researchers created mice which mimicked this human response, and found diets high in Neu5Gc linked to systemic inflammation, liver tumors and liver cancer.
Red meat including beef, pork, and lamb are high in Neu5Gc, especially their organ meats. Caviar is high, as well as cheese. There was “very little” in cows milk. Poultry, seafood, vegetables and fruit were free.
Based on this new data, the American Institute for Cancer Research advises we eat no more than 18 ounces of cooked red meat a week. [emphasis mine]
