Omega-3 fatty acid linked to positive impacts in behavioral and cognitive processes

A study published in the journal Food Science and Human Wellness found that omega-3 polyunsaturated fatty acids (PUFAs) play a role in cognitive and behavioral processes. In particular, adding omega-3 PUFAs to one’s diet improves attention and impulsive behavior.

  • Omega-3 PUFAs are believed to play a role in neuronal processes, such as in neurodevelopmental disorders and for integral central nervous system functioning.
  • Researchers from the University of Regensburg in Germany sought to determine the effects of omega-3 deficiency on attention functions and impulsive behavior in rats.
  • They also looked at the effects of a diet that includes adequate omega-3 PUFAs in omega-3 deficient rats on the same behavioral domains.
  • For the study, the researchers fed the rats with an omega-3 deficient diet over several generations, and the dams of the seventh generation were randomly assigned to two diet groups and a received an omega-3 deficient or an omega-3 sufficient diet.
  • Moreover, they fed a group of previously untreated dams with an omega-3 sufficient diet.
  • Then, the researchers examined the attention and impulsive behavior of the male offspring of these three diet groups.
  • The results showed that the deficiency of omega-3 PUFAs over generations resulted in significant changes in attentional processes and impulsive behaviors.
  • The treatment with the omega-3 sufficient diet partly corrected the impairments associated with an omega-3 deficiency.
  • In particular, omega-3 PUFAs caused significant improvements in attention parameters and in impulsive behavior.

In sum, these findings indicate that omega-3 PUFAs can improve attentional processes and impulsive behavior, supporting the hypothesis that these fatty acids are involved in cognitive and behavioral processes.
