Our previous results (Nakamura et al., 2013, 2016) indicated that acetylcholine (ACh) in orally administered foods exerts antihypertensive effects. Eggplants (Solanum melongena) contain abundant ACh (Horiuchi et al., 2003), and their food functionality was discovered, using spontaneously hypertensive rats, by
