Cooking oils that include those most commonly used by Americans have been cited in two separate studies as having links to increased rates of cancer.
One study that sought to estimate the health risks from seed oils such as canola oil, corn oil and cottonseed oil, found that men on the low end of seed oil consumption had slower-growing prostate cancer than men at the high end of seed oil consumption, according to the U.K. Daily Mail.
Seed oils contain high amounts of omega-6 fats which some studies have said can be linked to cancer growth.
In contrast, omega-3 fats, found in fish, are generally thought to be healthier.
“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,” Dr. William Aronson, a professor of urology at UCLA, said.
Current medical orthodoxy says seed oils – consumed in moderation – are not a direct cause of cancer.
In the UCLA study, half of the 100 participants ate a diet low in omega-6 fats and high in omega-3 fats. The rest ate as they always had.
The study group ate fewer fried foods, chips
