英语时差:健康饮食计划-上
One of the most commonly-held beliefs regarding health and nutrition in the UK has been found to be untrue, according to a new scientific study. For many years British people have been recommended to eat at least 'five-a-day' – that is five items of fruit or vegetables every day in order to improve their health and reduce the likelihood of illness, in particular cancer. The recommendation was first put forward in 1990 by the World Health Organization which said that the 'five-a-day' diet could prevent cancer and other chronic diseases. Since then the advice has been a mainstay of public health policies in many developed countries, such as the UK, where the population eat a high proportion of junk food. Many health campaigns have promoted the advice, and indeed much food packaging in Britain states how the contents will constitute part of your five-a-day.
