Nutritional studies link Omega-3 to reduced aggression and validate rapeseed oil safety

Recent scientific and consumer studies have provided new insights into dietary components. A 2024 meta-analysis by researchers at the University of Pennsylvania, reviewing 29 randomized controlled studies involving 3,918 participants, found that Omega-3 fatty acids may have a short-term effect on reducing aggressive behavior. Depending on variables such as age, gender, and dosage, aggression levels decreased by up to 28 percent.

In separate consumer testing, Stiftung Warentest evaluated 24 rapeseed oil products to address social media claims linking the oil to cancer and inflammation. The investigation found high quality across the board, with 22 of the 24 products receiving a ‘good’ rating. No significant levels of pesticides, plasticizers, or mineral oil hydrocarbons were detected. Furthermore, erucic acid levels remained well below the European Union limit of 2 percent, with most products showing negligible amounts.
