The next time you take the air down the produce gangway of your grocery shop , you may require to get to for scarlet Allium cepa if you are looking to fight off genus Cancer .
In the first study to examine how effective Ontario - grow onions are at killing Crab cell , U of G researchers have line up that not all onions are created adequate .
Researchers tested five onion types uprise in Ontario and discovered the Ruby Ring red onion smorgasbord come out on top .
Onions as a superfood are still not well known . But they contain one of the high concentration of quercetin , a type of flavonoid , and Ontario onions bluster particularly mellow levels of the compound compared to some percentage of the world .
The Guelph study revealed that the red Allium cepa not only has gamy levels of quercetin , but also high amounts of anthocyanin , which enrich the scavenge properties of quercetin mote , said Murayyan , field of study ’s hint source .
“ Anthocyanin is instrumental in provide colour to fruits and vegetables so it makes sense that the red onion , which are darkest in color , would have the most genus Cancer - fighting tycoon . ”
Published latterly in Food Research International , the study require placing colon malignant neoplastic disease cells in direct inter-group communication with quercetin educe from the five different onion plant varieties .
“ We found onions are excellent at kill cancer cells , ” articulate Murayyan . “ Onions actuate pathways that boost cancer cubicle to undergo cadre last . They advertise an unfavourable environment for genus Cancer cells and they disrupt communication between malignant neoplastic disease cells , which inhibits growth . ”
The investigator have also recently determined onion are good at killing breast Crab mobile phone .
“ The next step will be to test the veg ’s cancer - struggle powers in human trial run , ” said Murayyan .
These findings follow a recent study by the researchers on unexampled extraction technique that eliminates the use of chemical , making the quercetin found in onion more suited for use of goods and services .
Other descent methods habituate dissolvent that can get out a toxic remainder which is then ingested in food , read Neethirajan .
“ This new method that we tested to be efficient only use top-notch - heated up water in a pressurized container , ” he say . “ Developing a chemical substance - free origin method acting is authoritative because it means we can practice onion ’s cancer - fight properties in nutraceuticals and in pill material body . ”
While we can presently include this superfood in salad and on burgers as a preventative measure , the researcher expect onion extract will eventually be sum up to food production such as juice or baked goods and be sold in anovulant form as a eccentric of natural cancer treatment .
