Dr. Tim Kev, of the University of Oxford, told a cancer conference that scientists are still discovering how certain foods contribute to{{U}} (53) {{/U}}, but they know that diet, alcohol and obesity (肥胖){{U}} (54) {{/U}}a major role. "Five percent of cancers could be avoided{{U}} (55) {{/U}}nobody was obese(肥胖的)," he said.

Kev told the meeting of the charity Cancer Research UK{{U}} (60) {{/U}}other elements of diet linked to cancer are{{U}} (61) {{/U}}unknown but scientists are hoping that the EPIC study, which is comparing the diets of 500,000 people in 10 countries and their risk of cancer, will provide some{{U}} (62) {{/U}}. Early results of the study have revealed that Norway, Sweden and Denmark have the{{U}} (63) {{/U}}consumption of fruit and vegetables among European countries while Italy and Spain have the highest.
