Margarine can actually make you angry – and should not be fed to school pupils, a new study has warned.
A chemical called ‘trans fatty acids’ – found in large quantities in margarine, and also in other fast foods – makes people aggressive and irritable.
Researchers studied 945 people with varying diets – and found those who ate large quantities of the chemical were consistently more aggressive.
The researchers warn that schools – and prisons – should look their menus to ensure diet isn’t playing a part in aggressive behaviour.
Dr Beatrice Golomb – a professor at the University of California and lead author of the paper for Plos ONE – said: ‘We found that greater trans fatty acids were associated with greater aggression.
‘High levels of the trans fatty acids were more consistently predictive of aggression and irritability.
‘This adds further rationale to recommendations to avoid eating trans fats – the detrimental effects of trans fats may extend beyond the person who consumes them to affect others.’
The chemicals are already known to be bad for health – and can cause efffects such as high cholesterol levels, insulin resistance, oxidation, inflammation, and cardiac problems.
Fast food chain McDonalds switched oil to cut down trans fats after a lengthy campaign.
McDonald’s changed to a new oil which halved the trans fatty acid levels in its french fries while increasing the amount of the more beneficial polyunsaturated fat
They questioned participants’ on life history of aggression, conflict tactics and self-rated impatience and irritabilty on an ‘overt aggression’ scale – tallying recent aggressive behaviour.
The results – adjusted for sex, age, education and use of alcohol or tobacco products – showed there was a link between those eating foods containing the chemicals, and heightened aggression.
