Myth: You need to eat five portions of fruit and veg a day
误区三：每日五蔬果
"Five-a-day is the most well-known piece of nutritional advice," says Harcombe. "You'd think it was based on firm evidence of health benefit. Think again!"
赫尔康比说：“每日五蔬果的营养建议可谓家喻户晓。如果你认为有充足的证据来证实此建议有益身体健康，那么你就又错了!”

"Five-a-day started as a marketing campaign by 25 fruit and veg companies and the American National Cancer Institute in 1991. There was no evidence for any cancer benefit."
“每日五蔬果的建议最早是由25家果蔬销售公司与美国国家癌症研究中心在1991年联合推出的营销策略。目前尚无证据表明它有抗癌作用。”
