Omega-3's Enhance Brain Benefits of Exercise
Docosahexaenoic acid (DHA) is one of two omega-3 fatty acids found in animal foods (the other is EPA). DHA has been shown to enhance the function of the brain by increasing neuoplasticity, or the brain's ability to generate new neurons and create connections between them. Exercise is also known to promote neuroplasticity.
Researchers from the University of California at Los Angeles recently sought to determine whether DHA supplementation would boost the neuroplasticity-promoting effect of exercise. Rats received supplemental DHA with or without exercise for a period of 12 days. The researchers found that DHA increased markers of neuroplasticity such as brain-derived neurotrophic factor (BDNF), while the combination of DHA and exercise increased them more. The same pattern was seen with spatial learning ability, with DHA plus exercise generating the greatest improvements.
The authors of the study, which was published in the journal Neuroscience, concluded, "These results indicate that the DHA diet enhanced the effects of exercise on cognition and BDNF-related synaptic plasticity, a capacity that may be used to promote mental health and reduce risk of neurological disorders." |
