     An overweight, middle-aged man lies dead on a trolley, with a woman weeping over his body. The

body's cold hand still grasps a half-eaten McDonald's hamburger. American doctors' TV ad features the

image which weakens the slightest of appetites and the line "I was lovin' it".

     The hard-hitting US television commercial supported by a Washington-based medical group has angered

McDonald's by taking an unusually direct shot at the world's biggest fast-food chain this week. The line is

a twist on McDonald's long-standing advertising slogan, "I'm lovin' it" and a voice-over intones, "High

cholesterol, high blood pressure, heart attacks. Tonight, make it vegetarian."

     The commercial, funded by the Physicians Committee for Responsible Medicine (PCRM), goes further

than most non-profit advertising and has drawn an angry reaction from both the Chicago-based hamburger

multinational and the broader restaurant industry.

     The National Restaurant Association criticized it as "irresponsible" and said it was an attempt to scare the

public with a "limited" view of nutrition. A McDonald's spokesman said,"This commercial is unbearable,

misleading and unfair to all consumers. McDonald's trusts our customers to make food and lifestyle choices

that are right for them."

     The commercial, to be aired at the beginning in the Washington area but potentially in further US cities,

comes amid an increasingly lively debate in the US about healthy eating. The first lady, Michelle Obama, has

made nutrition a signature issue and is leading a campaign to encourage physical fitness and improved diets-

particularly among American children, a third of whom are overweight.

     The economic decline has hardly helped the healthy eating cause. McDonald's has enjoyed a relatively

prosperous financial crisis as diners choose its affordable offerings in place of more expensive high-street

restaurants. Its global profits for the six months to June were up 12% to $ 2.3 billion, powered by sales rises

both in the United States and Britain.

     The PCRM's director of nutrition education, Susan Levin, made no apologies for singling out the golden

arches (拱门):"McDonald's is one of the biggest fast-food chains in the world. Its name and its golden arches

are instantly recognizable. We feel we're making a point about all fast food when we talk about McDonald's."
