Eating Red Onions Help Kill Cancerous Tumours As Onions Prevent Growth Of Cancer Cells – New Study Tweet


– Health Talk: Eating Red Onions
Help Kill Cancerous Tumours As Onions Prevent
Growth Of Cancer Cells
A new research has confirmed that eating red
onion, a common, vegetable used in cooking
around the world, may help to fight cancer.
According to the study, which was presented at
the ‘Food Research International’ forum, the tasty
vegetable is full of powerful compounds that help
to kill tumours.
One type of the red onion known as anthocyanins,
which was responsible for its dark colouring, were
believed to be inhibiting the spread of the disease.
A flavonoid called quercetin, one of the
compounds, had the same effects by shrinking the
size of cancerous masses, medical experts had
affirmed.
According to Canadian scientists, any type of
onion, regardless of its colour, may help to destroy
cancer. Cancer is a group of diseases involving
abnormal cell growth with the potential to invade or
spread to other parts of the body.
Not all tumors are cancerous; benign tumours do
not spread to other parts of the body.
Study author, Abdulmonem Murayyan, of the
University of Guelph, Canada, said: “We found
onions are excellent at killing cancer cells.
“Onions activate pathways that encourage cancer
cells to undergo cell death.
“They promote an unfavourable environment for
cancer cells and they disrupt communication
between cancer cells, which inhibits growth.”
Similarly, “the red onions, which are darkest in
colour, have the most cancer-fighting power.” For
the new study, the researchers placed colon cancer
cells in direct contact with quercetin extracted from
five different onion varieties.
The Ruby Ring onion was found to be the most
potent. During recent studies, the researchers also
determined that onions were effective at killing
breast cancer cells.
The researchers said: “It was found that extracts
from certain types of onions could kill bowel
cancer cells in a laboratory, but that doesn’t mean
the same would happen in a person’s body, which
was much more complex.
“If scientists can tease out which molecules in
onions have these apparently beneficial effects,
then perhaps they could be investigated as a
potential drug in the future.
The scientists were now aiming to test the
vegetable’s cancer-fighting properties in human
trial in the coming years. Onions were known to
contain one of the highest concentrations of
quercetin in the vegetable world.
