This myth has gained traction online, but it doesn’t hold up under scientific scrutiny. Much of the fear stems from ignorance about fats and inflammation. The claim is that seed oils are dangerous because they contain omega-6 fatty acids, which are said to “cause inflammation.” This is an oversimplification. Omega-6 fats are essential fats—our bodies need them to function. An extreme overload of omega-6 compared to omega-3 will promote inflammation, but this never happens in human diets. Decades of research show that normal consumption of omega-6 fats does not increase inflammation or disease risk in humans. In fact, replacing animal fats with seed oils is known to have several beneficial effects.
