Abstract:
Sacha Inchi oil consists of omega-3, a key component affects the nervous system by increasing the potential of memory and concentration. This study aimed to examine the efficacy of Sacha Inchi oil on cognitive function. Subjects were divided into two groups of 15 people for each group by Randomized double-blind controlled trial. Experimental group received 5 soft gels of Sacha Inchi oil per day, and control group received 5 soft gels of placebo per day for 35 days. The total dose of Omega-3 in 5 soft gels of Sacha Inchi oil is 1.75 grams. Result of the cognitive function test; Attention Go/Nogo test showed that the experimental group, compared within the same group, has the score of fastest time and average response time better than before experiment. (p-value = 0.04, and 0.03) This result represents the improvement part of the brain - inferior frontal cortex, both side of anterior insular cortex, anterior-ventral region of anterior commissure, center of connection part of prefrontal cortex, anterior commissure connecting the center of prefrontal cortex and supplementary motor area. Furthermore, the result of the cognitive function test; Memory N-Back test showed that the improvement of average response time and percentage of accuracy within the same group of Sacha Inchi oil by comparing before and after (p-value = 0.04 and 0.04). The N-Back test score represents temporal lobe.
In conclusion, Sacha Inchi oil supplement increase cognitive function in part of attention and memory by comparing to the same group before and after experiment.
