In a study led by Dr Carlos Ibarren, a researcher with Kaiser Permanente in Oakland, tests carried out on 3581 urban adults showed that an increased consumption of fish high in omega-3 fatty acids was an independent predictor of a lower scoring in measurements of hostility, including cynicism and mistrust of others, anger and aggression.
The results of the tests, which were performed on adults aged 18-30, were adjusted to allow for the impact of factors such as age, gender, race, education, smoking, alcohol intake and weight. They were published in the January issue of the European Journal of Clinical Nutrition.
These heart-healthy omega-3 fatty acids are found in oily fish such as salmon, mackerel and tuna.
