This so-called “healthy” fat might be doing more harm than good

Researchers at the University of Oklahoma found that oleic acid, the main fat in extra-virgin olive oil, can significantly increase the creation of new fat cells in mice. This raises concerns that a diet high in oleic acid could lead to obesity and chronic diseases. While olive oil has been touted for its health benefits, the study highlights the importance of moderation and considering the context in which fats are consumed.

The study emphasizes the need to be mindful of the amount of oleic acid consumed, as well as the source and variety of fats in the diet. It suggests swapping some liquid oils for whole-food fats like avocados, nuts, and seeds to maintain a balanced fat intake. The findings also prompt a shift towards looking at the overall dietary pattern rather than focusing solely on single “healthy” fats.
