Omega-3 fatty acids – found in foods like salmon, soybeans and tofu – may help in the prevention of some oral and skin cancers, according to a study in the journal Carcinogenesis.
Researchers at Queen Mary University in London cultivated several types of malignant oral and skin cancer cells in a laboratory and then added fatty acids into the cell cultures, monitoring the effects.
According to Kenneth Parkinson, head of the oral cancer research group at Queen Mary’s Institute of Dentistry, the results were promising.
“We found that the omega-3 fatty acid selectively inhibited the growth of the malignant and pre-malignant cells at doses which did not affect the normal cells,” Parkinson said. “Surprisingly, we discovered this was partly due to an over-stimulation of a key growth factor (epidermal growth factor) which triggered cell death. This is a novel mechanism of action of these fatty acids.”
