据外媒报道，英国地方政府协会（LGA）敦促英国政府，针对所有食品生产厂实施强制性交通信号灯标签。
标签
交通信号灯标签对包装食品的不同营养成分进行打分（比如盐、热量、糖、脂肪内容物），红色表示不健康、琥珀色表示适中、绿色表示健康。交通灯标签目前仅用在英国三分之二的产品中。
部分原文报道如下：
Food manufacturers should be forced to put “traffic light” nutrition labels on the front of packs， councils have said.
The voluntary scheme， introduced by the Department of Health in 2013， sees foods highlighted as red， amber or green according to how much salt， sugar and fat they contain.
But the labels do not appear on about a third of the food sold in the UK.
