People who find themselves feeling consistently irritable and aggressive could be consuming too much dietary trans fatty acid (dTFA). This is the finding of a new study at the University of California, San Diego School of Medicine In a study of nearly 1,000 men and women in the US, it was found that dTFA cause adverse behaviours. Previous research has shown that excessive amounts of dTFA can effect lipid levels, metabolic function, insulin resistance, and cardiac health. However, this is the first study to link the acids to behavioural complications, using dietary information and psychological assessments. Dr Beatrice Golomb, leader of the research, commented: "If the association between trans fats and aggressive behaviour proves to be causal, this adds further rationale to recommendations to avoid eating trans fats, or including them in foods provided at institutions like schools and prisons." Some of the most common foods containing dTFA are margarine, packaged cake mix, and frozen meals. Find the nearest Barchester care home.
