CANBERRA, Oct. 4 (Xinhua) -- A visiting U.S. obesity expert, Kelly Brownell, on Tuesday called on Australia to make a start on taxing high-sugar soft drinks.As director of U.S. Yale University's Rudd Center for Food Policy and Obesity, Professor Brownell is in Canberra of Australia to attend the 46th Australian Psychological Society Annual Conference.He said soft drinks were a good place to start in the taxing of high-sugar foods because they were the single greatest source of added sugar in the average person's diet, had absolutely no nutritional value, were marketed aggressively and were linked with the risk for obesity and diabetes.While obesity has overtaken smoking as the leading cause of premature death and illness in Australia, he said the government should tax soft drinks in the same way it taxes cigarettes, because research showed that taxes had been the strongest influence on falling rates of consumption."We have seen how effective tobacco taxes have been in reducing rates of smoking, so there is no reason to believe such taxes wouldn't be as effective in reducing the consumption of high sugar and fat foods," Brownell, who was named by Time magazine as one of the 100 most influential people in the world, told the conference in Canberra on Tuesday. "A soft-drink tax is a good place to start. "Earlier this week, Denmark became the first country to impose a tax on food containing saturated fats, and Brownell said he completely supports Denmark's policy and that governments should act courageously to do whatever is effective in encouraging better eating habits.According to the Organisation for Economic Co-operation and Development report, Australia is ranked as one of the fattest nations in the developed world. The prevalence of obesity in Australia has more than doubled in the past 20 years, with more than 17 million Australians are overweight or obese.

BEIJING, Jan. 10 (Xinhua) -- Chinese State Councilor Dai Bingguo on Tuesday attended a reception at the Great Hall of People in Beijing celebrating the 20th anniversary of the establishment of diplomatic ties between China and five Central Asian countries.China successively established diplomatic relations with Uzbekistan, Kazakhstan, Kyrgyzstan, Tajikistan and Turkmenistan in early January of 1992.In his address, Dai said relations between China and the five nations have achieved comprehensive and significant progress since they forged diplomatic ties 20 years ago, featuring frequent high-level visits, deepened political mutual trust, mutual support on major issues of each other's concern and expanded mutually beneficial cooperation in various fields.China and the five countries have maintained close coordination within the framework of the United Nations and the Shanghai Cooperation Organization and have positively contributed to safeguarding and promoting the world's peace, stability and development, he said.Noting China and the Central Asian nations are good neighbors, good friends and good partners, Dai said, no matter how the international situation changes, China will adhere to the policy of building friendship and partnership with its neighbors and support the five nations to independently choose their development path.China will unswervingly advance traditional friendship and cooperation with the five nations and will work with them to make unremitting efforts for building a harmonious world of lasting peace and common prosperity, he said.Dai said China will take the opportunity of celebrating the 20th anniversary to increase political mutual trust, expand mutually beneficial cooperation and develop traditional friendship with the five nations, in the hope of jointly creating a bright future for their relations.Li Xiaolin, president of the Chinese People's Association for Friendship with Foreign Countries, and diplomatic envoys from the five Central Asian nations also addressed the reception.

WASHINGTON, Nov. 22 (Xinhua) -- Long-term coffee consumption may be associated with a reduced risk for endometrial cancer, according to a study published online Tuesday in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.Edward Giovannucci, professor of nutrition and epidemiology at the Harvard School of Public Health, said that coffee is emerging as a protective agent in cancers that are linked to obesity, estrogen and insulin."Coffee has already been shown to be protective against diabetes due to its effect on insulin," said Giovannucci, a senior researcher on the study. "So we hypothesized that we'd see a reduction in some cancers as well."The researchers observed cumulative coffee intake in relation to endometrial cancer in 67,470 women who enrolled in the Nurses' Health Study. During the course of 26 years of follow-up, researchers documented 672 cases of endometrial cancer.Drinking more than four cups of coffee per day was linked with a 25 percent reduced risk for endometrial cancer. Drinking between two and three cups per day was linked with a seven percent reduced risk.A similar link was seen in decaffeinated coffee, where drinking more than two cups per day was linked with a 22 percent reduced risk for endometrial cancer.Giovannucci said that he hopes this study will lead to further inquiries about the effect of coffee on cancer because in this and similar studies, coffee intake is self-selected and not randomized.

BEIJING, Nov. 22 (Xinhuanet) -- Global AIDS deaths and new HIV infections have each dropped 21 percent since the peak of the AIDS pandemic in 1997, according to a UN report released Monday.One major factor responsible for the result is that life-saving HIV treatments have become more popular and got to 1.35 million more people in 2010 than in 2009.In middle-income and underdeveloped nations, these treatments have saved 2.5 million lives since 1995."We have seen a massive scale-up in access to HIV treatment, which has had a dramatic effect on the lives of people everywhere," said Michel Sidibe, executive director of the U.N. AIDS program.However, 53 percent of people who need HIV/AIDS treatments -- about 7.6 million people -- cannot get them, which accounted for 1.8 million AIDS deaths in 2010.There are now 34 million people living with HIV. And just in last year there were 2.7 million new infections.The decline in deaths and new infections means the AIDS pandemic is at a turning point, the UNAIDS report argues, adding smart investment can save millions of future deaths.
