Fish oil supplements questioned
These pills are often seen as a way to increase heart-healthy omega-3 fatty acids, but this might not be the case, according to a recent study from UBC. In a study conducted on mice, UBC assistant professor of biology Sanjoy Ghosh found that mice which were already eating a diet including vegetable oil actually has less ability to repair cells in their gastrointestinal system when they were fed fish-oil supplements as well.
“Our hypothesis is that levels of omega 6 [fats found in vegetable-based oils] are so high in our bodies that any more unsaturated fatty acid — even omega 3, despite its health benefits — will actually contribute to the negative effects omega 6 PUFA have on the heart and gut,” Ghosh told The Vancouver Sun. “When there is too much [polyunsaturated fatty acid], the body doesn’t know what to do with it.”
Ghosh’s work was published in the British Journal of Nutrition.
