HONG KONG: Chinese scientists have recommended a region-specific diet they say is crucial to improving eating habits in the country amid a rise in obesity and lifestyle diseases, and as a means to conserve natural and environmental resources. China in October published its first set of guidelines to standardise the diagnosis and treatment of obesity, with more than half of China’s adults already overweight and obese, and the rate expected to keep rising. The government has said that healthier diets are important to treat and prevent obesity. A group of scientists from the School of Public Health at Sun Yat-sen University in Guangzhou, in China’s affluent southern Guangdong province, said its study adheres to a “Planetary Health Diet” and advocates a reduced consumption of dairy products and red meat. Published in the Nature Food journal in August and reported in state media last week, the study recommended that in China’s north, which is characterised by a high intake of dairy products but low consumption of vegetables, people need to eat more fruits and whole grains. In the southwest, which has a harsher environment and severe water scarcity, the region could focus on a high intake of legumes and vegetables rather than its existing very high consumption of red meat, the study said.
