Passage 4
A man from New York is suing four big fast-food companies. Caesar Barber is going to   court because he says that high-fat foods at McDonald’s, Burger King, Wendy’s, and KFC  Corporation destroyed his health. Barber says that he ate at these restaurants four or five times a  week for many years. He claims that this diet made him very overweight. According to Mr. Barber,  obesity (肥胖症) gave him diabetes (糖尿病), high blood pressure, and, two heart attacks. When a  reporter asked him why he ate there so often, he said,“I was single, it was quick, and I’m not a  very good cook.”
Barber’s lawyer, Samuel Hirsch, says that the suit has two different purposes. The first   is to make fast-food restaurants offer healthier foods in smaller amounts. The suit also asks that  fast foods have warning labels similar to labels on cigarettes Mr. Hirsch says that these labels are  necessary because the effects of fast foods are similar to the effects of cigarettes, alcohol, and  illegal drugs such as heroin.
Two others may soon join Barber’s suit. One is Frances Winn, a 57-year-old retired   nurse. Ms. Winn says that she has eaten at fast-food restaurants at least twice a week since 1975.  She says that this habit has caused several health problems, including high blood pressure. Isreal  Bradley,59,said eating a pound of French fries every week gave him high blood pressure and  diabetes.
Officals of the fast-food industry attacked the legal action, National Restaurant   Association representative Katharine Kim called it ridiculous. KFC spokeswoman Amy Sherwood  claimed KFC offers several kind of foods for people who want to eat healthier. Legal expert  Walter Olson agreed that the suit had little chance of success. He said that people were free to  make different choices.
Whether or not the suit is successful, there is no doubt that Americans have a weight   problem. Medical experts say that obesity will soon be America’s number one killed. They have  encouraged fast-food companies to offer healthier foods.
