　　甜土豆富含纤维，维生素A和钙。但是科学家心目中的更健康的食用方式简直令人震惊。研究人员发现给甜土豆充电会将抗氧化剂(即多酚)的水平提高60%。

　　The investigators placed sweet potatoes in asolution of sodium chloride. They found that 0.2amps of direct current gave the potatoes nearly one and a half times more antioxidants thanpotatoes that weren't shocked. The research was presented at the National Meeting of theAmerican Chemical Society.

　　调查人员将甜土豆放置在氯化钠溶液中。他们发现0.2安培的直流电会让土豆产生比正常状态多出将近1.5倍的抗氧化剂。美国化学学会国内会议展示了这项研究。

　　It seems that the electric zap stressed the potatoes into producing more polyphenols as aprotective mechanism. And the treatment did not sacrifice flavor.

　　似乎电击能刺激土豆产生更多的抗氧化物，对土豆来说也许是一个保护机制。同时电击并不影响土豆原有的口味。

　　Previous research has shown that electrically supercharging white potatoes increasesantioxidant levels. So perhaps it's only a matter of time before other fruits and vegetables getshock therapy, too.

　　之前的研究也显示，高压电击土豆会提高抗氧化剂水平。也许让其它水果，蔬菜接受“电疗”以增加营养价值只是时间问题了。
