Effect of GABA-enriched white rice on noradrenaline
Although the mechanism underlying the hypotensive action of GABA intake has not been fully elucidated, it is suspected that this action may be due to GABA’s ability to inhibit noradrenaline release from sympathetic nerve fibers.17Fig. 4 shows the results of the participants’ serum noradrenaline levels before and after the intake of a test/placebo meal. There was no significant difference between the two groups.
