Diners at Yoshinoya restaurants nationwide will be able to order will be able to order gyudon (beef bowls) with extract of salacia — a plant that curbs the rise in blood glucose levels — starting on Monday, according to an announcement by Yoshinoya Holdings Co. on Thursday.
The company hopes that the new offering, which tastes just like regular gyudon, will be popular among middle-aged customers who may be more conscious of monitoring their blood sugar.
The price of the gyudon with salacia will cost ¥100 more the standard beef bowl, which is priced at ¥480 for a regular-size bowl.
The restaurant chain had previously sold gyudon ingredient packs containing salacia extract online only. This drew a number of requests for salacia to be added to the Yoshinoya restaurant menu.
Salacia, which grows mainly in India and Southeast Asia, has long been used for tea. The plant is believed to inhibit enzymes that support sugar absorption, thereby slowing the pace of a rise in blood sugar levels.
