Electronics maker Fujitsu Ltd. has begun selling low-potassium lettuce, which is grown in a special clean room at its semiconductor plant in Aizu-Wakamatsu, Fukushima Prefecture.
Normally, vegetables need to be heated to decrease potassium levels. However, patients suffering from kidney disease or those undergoing dialysis — who are restricted in their potassium intake — can now enjoy salad made with Fujitsu’s lettuce, which the company began selling May 7.
Fujitsu renovated a section of one of its virtually dust-, germ- and sunlight-free clean rooms at the plant to create the Aizu-Wakamatsu Akisai Vegetable Plant. The low-potassium lettuce is the first installment of its "Kirei Yasai" (Clean Vegetable) series.
