Omega-3 deficiency may explain depressive behavioursPublished On: Mon, Jan 31st, 2011 | Neurobiology | By BioNews
A new study has said that dietary insufficiency in omega-3 fatty acid may explain deleterious consequences on synaptic functions and emotional behaviours.
These fatty acids are “essential” lipids because the body cannot synthesize them from new. They must therefore be provided through food and their dietary balance is essential to maintain optimal brain functions.
Researchers from Inserm and INRA and their collaborators in Spain collaboration, studied mice fed on a diet low in omega-3 fatty acid.
“Our results can now corroborate clinical and epidemiological studies which have revealed associations between an omega-3/omega-6 imbalance and mood disorders”, said Olivier Manzoni and Sophie Laye.
“To determine if the omega-3 deficiency is responsible for these neuropsychiatric disorders additional studies are, of course, required”.
The study appears in Nature Neuroscience. (ANI)
