LONDON (Reuters) - Drinking less alcohol, eating more vegetables and exercising can prevent or delay the onset of diabetes, researchers said on Friday in a study showing that lifestyle changes can make a big difference.

Diet and exercise reduced the incidence of diabetes by about 43 percent over 20 years among 577 high-risk Chinese adults, the researchers reported in the journal Lancet.

At the end of the 20 years, 80 percent of those who changed what they ate and exercised more had diabetes, compared with 93 percent who made no changes, said Guangwei Li of the China-Japan Friendship Hospital in Beijing and Ping Zhang at the U.S. Centers for Disease Control and Prevention.
