Restaurants, including food chains Planet Hollywood, All Bar One and Shoeless Joes, are prepared to serve rare hamburgers, sausages or minced beef only if diners sign forms giving up rights to take legal action if they become poisoned. Scientists say that if people eat minced beef that is pink in the middle, they are more likely to be poisoned by E-coli or salmonella. The new disclaimer practice is blamed on health advice from the governments food safety watchdog, saying that minced meat should only be served when it is well-done. The warning does not apply to ordinary steaks, because they only carry bacteria on the outside and this is killed by cooking. Egon Ronay, the restaurant critic, attacked the disclaimers: “I dont know where it will all stop soon you will have to fill in a huge disclaimer from before setting foot in a restaurant!”Listening Task 11.

Cocoa, the source of chocolate, contains compounds that can help protect you against arteriosclerosis. Prof. Davis, a researcher from the University of California, told people that human trials showed that eating chocolate could lessen clotting of blood cells, which is linked to cardiovascular diseases. “With balance and moderation, chocolate can contribute to a healthy diet,” said Davis. Volunteers were fed chocolates while the antioxidant capacity of their blood was measured. Antioxidants, also found in fresh vegetables, fruit and red wine, scavenge blood to get rid of free-radical substances linked to cancer and some chronic diseases. Scientists have already suggested that the fat in chocolate, from cocoa butter, could be beneficial. Louis Grivetti, from the same university, said that cocoa beans were used as medicine by the Mexican Indians as early as in the 16th century. Over the following 400 years, manuscripts revealed 100 medical uses of chocolate which included curing exhaustion and over-excitement. 1. T2. F3. F4. T5. F1-5. T F F T FListening Task 21. Topic: Chocolate and Health 2. Main argument: Eating chocolate is good for peoples health. 3. Scientific basis of the argument: The antioxidants found in chocolate scavenge the blood to get rid of disease-causing substances and thus reduce clotting of the blood cells.4.
