A brand new research from the College of Waterloo makes use of mathematical modeling to look at how Vitamin C impacts chemical reactions within the digestive system which might be linked to most cancers improvement.
Over the past a number of a long time, North American diets have seen a gentle enhance in publicity to nitrates and nitrites: compounds present in cured meats in addition to vegetables and fruit grown utilizing polluted soil and water. Whereas nitrates and nitrites play essential roles in neurological and coronary heart well being, within the abdomen, they will endure a chemical response often known as “nitrosation” and kind chemical compounds that many scientists suspect enhance most cancers danger.
Since not less than the 90s, researchers have been learning the hyperlink between most cancers and these compounds, with conflicting outcomes. Our work means that the presence of dietary Vitamin C could assist clarify these inconsistencies.”

The staff constructed a mathematical mannequin of the salivary glands, abdomen, small gut and plasma, and simulated how nitrites and nitrates transfer by means of the physique and alter over time. Their mannequin demonstrated that when Vitamin C can be current in meals, equivalent to leafy greens like spinach, which include each Vitamin C and nitrate, it may lower most cancers danger.
The research additionally steered that taking Vitamin C dietary supplements after every meal may have a reasonable constructive impact in lowering the formation of nitrosation merchandise related to most cancers danger from dietary nitrites and nitrates, equivalent to these present in meals like bacon and salami.
The researchers hope these findings will help future diet analysis.
“This work gives a mechanistic roadmap for future medical and laboratory research by figuring out the important thing interacting drivers of those probably dangerous chemical reactions, together with nitrite publicity, antioxidant consumption, meal timing, gastric situations and oral microbiome exercise,” stated Dr. Anita Layton, professor of utilized arithmetic and Canada 150 researcher chair. “This mannequin might help researchers design extra focused experiments and interventions, specializing in when and in whom nitrosation is almost definitely to happen.”
The analysis, “Vitamin C as a nitrosation inhibitor: A modelling research throughout dietary patterns and water high quality,” seems within the Journal of Theoretical Biology.
