Eating flaxseed may halt prostate cancer growth
Flaxseed,, which is rich in omega 3-fatty acids and fibre-related compounds
known as lignans, may interrupt the chain of events that cause cells to divide
irregularly and become cancerous, suggest researchers from the Duke University
Medical Center in the United States.
\\\"Our previous studies in animals
and humans had shown a correlation between flaxseed supplementation and slowed
tumour growth, but the participants in those studies had taken flaxseed in conjunction
with a low-fat diet,\\\" said Wendy Demark-Wahnefried, a researcher in Duke\\\'s
School of Nursing and lead investigator on the study.
\\\"For this study,
we demonstrated that it is flaxseed that primarily offers the protective benefit,\\\"
The study involved men scheduled to undergo surgery for
the treatment of prostate cancer. The researchers gave them 30 grams of flaxseed
every day for an average of 30 days.
When the men\\\'s tumours were removed,
the researchers were able to determine how quickly the cancer cells had multiplied.
The men taking flaxseed, either alone or in conjunction with a low-fat
diet, were compared to men following just a low-fat diet, and men in a control
group, who did not alter or supplement their daily diet. Each group was made up
of about 40 participants.
Men in both of the flaxseed groups had the slowest
rate of tumour growth, according to the researchers.
The study was presented
at the annual meeting of the American Society of Clinical Oncology in Chicago
on Saturday. NutraIngredients.com has not seen the full results, and publication
status is unknown.
\\\"The results showed that the men who took just flaxseed
as well as those who took flaxseed combined with a low-fat diet did the best,
indicating that it is the flaxseed which is making the difference,\\\" Demark-Wahnefried
She suggested that as a source of omega-3 fatty acids, flaxseed may
alter how cancer cells lump together or cling to other body cells. It could therefore
help halt the cellular activity that leads to cancer growth.
lignans may have antiangiogenic properties, meaning they are able to choke off
a tumour\\\'s blood supply and stop it spreading, added the researchers.
took the flaxseed in a ground form to make it more digestible and mixed it in
drinks or sprinkled it on food such as yogurt.
The researchers now hope
to test the effectiveness of flaxseed supplementation in patients with recurrent
Over half a million news cases of prostate cancer are
diagnosed every year worldwide, and the cancer is the direct cause of over 200,000
deaths. Most worryingly, the incidence of the disease is increasing with a rise
of 1.7 per cent over 15 years.
