University of California, San Diego researchers have provided the first evidence linking the consumption of trans fats with a range of adverse behaviors, ranging from impatience and irritability, to overt aggression. The findings, inPLoS ONE, may lend some scientific muscle to lawyers looking to employ Twinkie defensestrategies in the courtroom.
Dietary trans fatty acids (dTFAs) are products of hydrogenation, which makes unsaturated oils solid at room temperature. They are present at high levels in margarines, shortenings and prepared foods. Previous studies have identified their adverse effects on lipid levels, metabolic function, insulin resistance, oxidation, inflammation and cardiac health.
The new study of nearly 1,000 men and women was led by Beatrice Golomb and used baseline dietary information and behavioral assessments to analyze the relationship between dTFAs and aggression. She measured factors such as history of aggression, conflict tactics and self-rated impatience and irritability, as well as an “overt aggression” scale that tallied recent aggressive behaviors. The results were adjusted for sex, age, education and use of alcohol or tobacco.
If the association between trans fats and aggressive behavior does prove to be causal, Golomb suggests that schools and prisons might benefit from foodstuffs containing trans fats being removed from the menu.
