Cancer patients who cut seed oil out of their diet may be able to slow their tumors, according to a new study.  

By studying 100 men with early-stage prostate cancer over one year, researchers found those who ate less foods with vegetable oil and more foods like salmon had slower growing cancer than people who ate a normal western diet. 

Seed oils - which include canola oil, corn oil and cottonseed oil - are high in omega-6 fats which some studies suggest may increase inflammation, making it easier for cancer to take over your system. 

By contrast, oils found in fish are high in omega-3 fats, which are thought to protect against inflammation and support the immune system. 

Dr William Aronson, a professor of urology at UCLA school of medicine who led the study, said: 'Our findings suggest that something as simple as adjusting your diet could potentially slow cancer growth and extend the time before more aggressive interventions are needed.'

The leading US medical bodies all say that seed oils are safe and are not linked to cancer or other diseases. 

But public opinion, partially lead by figures like Robert F Kennedy Jr, has been scrutinizing the popular ingredient, who say the oils are 'driving the obesity epidemic'. 

The new study comes just days after research from University of South Florida published earlier this week linked seed oils to the increase in colon cancer cases in young people.
