A recent study from Weill Cornell Medicine suggests that consuming excessive cooking oil, particularly seed oils high in linoleic acid, may increase the risk of cancer. Linoleic acid, an omega-6 fatty acid, has been linked to an aggressive subtype of breast cancer known as triple-negative breast cancer (TNBC). While the findings do not call for a complete avoidance of seed oils, experts recommend moderation and selectivity, especially for high-risk individuals. To maintain overall health and reduce cancer risk, experts emphasize the importance of a balanced, whole-food diet.
