"This new method that we tested to be effective only uses super-heated water in a pressurised container," he said."Developing a chemical-free extraction method is important because it means we can use onions cancer-fighting properties in nutraceuticals and in pill form," he added.Onions activate pathways that encourage cancer cells to undergo cell death.These findings follow a recent study by the researchers on new extraction technique that eliminates the use of chemicals, making the quercetin found in onions more suitable for consumption."We found onions are excellent at killing cancer cells," said Abdulmonem Murayyan, post doctoral student at University of Guelph.Toronto: Eating red onions may help fight cancer, say scientists including one of Indian origin, paving the way for a natural pill that can treat the deadly disease They contain one of the highest concentrations of quercetin, a type of flavonoid, they said.The study was published in the journal Food Research International.
Onions as a superfood are still not well known.The team found that red onions not only have high levels of quercetin, but also high amounts of anthocyanin, which enriches the scavenging properties of quercetin molecules."The next step will be to test the vegetables cancer- fighting powers in human trials," said Murayyan.Other extraction methods use solvents that can leave a toxic residue which is then ingested in food, said Suresh Neethirajan, professor at University of Guelph.The team tested five onion types grown in Ontario and discovered that the Ruby Ring onion variety - that has hard, firm, tall globe-shaped bulbs with dark red colour features - has the strongest cancer-fighting power. They promote an unfavourable environment for cancer cells and disrupt communication between cancer them, which inhibits growth, researchers from University of Guelph in Canada said.While we can currently include this superfood in salads and on burgers as a preventative measure, the researchers expect onion extract will eventually be added to food products such as juice or baked goods and be sold in pill form as a type of natural Red onion head Wholesale cancer treatment.
