Saturated fatty acids: an impact on the brain and behaviour
Excessive consumption of saturated fatty acids would have an impact on behavior, as well as brain function. Overconsumption of fat is already recognized for itsharmful effects on metabolism, as well as the cardiovascular system. In this recent Canadian study published in the journal Neuropsychopharmacology(1), scientists explain that saturated fatty acids can alsoalter brain function, as well as behaviour.
Consequences on dopaminergic function
The Université de Montréal researchers conducted their study on three groups of rats. Each group consumed a different diet for eight weeks, namely, low in fat, high in monounsaturated fatty acids based on olive oil, as well as rich in saturated fatty acids including palm oil.
At the end of the eight weeks, the rats maintained an almost identical weight, regardless of the diet consumed. However, differences emerged regarding behaviour within each group. The scientists explain that rats that consumed the palm oil diet displayed less effective dopaminergic function than the other groups.
Specifically, dopamine represents an important neurotransmitter involved in communication between different “dopaminergic” neurons playing a role in alertness and pleasure sensations.
An impact on eating habits
The conclusions of the study lead scientists to determine a hypothesis: the overconsumption of saturated fatswould encourage eating in greater quantities and especially more fat. Unsaturated fatty acids would help reduce the sensations of pleasure related to the meal, which would directly influence eating habits.
What’s more, this impact on dopaminergic function only affects saturated fatty acids, such as palm oil, says lead study author Stephanie Fulton.
Indeed, the various tests carried out have shown that this decrease does not concern the diet based on unsaturated fats, such as olive oil.
Be aware that saturated fatty acids are mainly found in animal fats, such as butter, cream or cheese, as well as in vegetable oils, such as palm oil.
These fatty acids, consumed as part of a balanced diet are harmless. However, an excesspromotes the risk of the onset of serious diseases, such as cardiovascular diseases.
