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.

RIYADH, Jan. 14 (Xinhua) -- China and Saudi Arabia pledged to work together to further expand all-around exchanges and cooperation as Chinese Premier Wen Jiabao Saturday unfolded his official visit to the Middle East kingdom.China and Saudi Arabia have treated each other as equals with respect and their cooperation has been fruitful since the establishment of diplomatic ties 22 years ago, said Wen while meeting Crown Prince Nayef bin Abdulaziz Al Saud.In recent years, despite the fact that international and regional situation became ever complicated and volatile, the two countries have strengthened high-level exchanges and promoted political mutual trust, said Wen, adding that the two have always demonstrated mutual understanding and support on issues involving their core interests and of major concern.Chinese Premier Wen Jiabao (L) holds talks with Saudi Arabia's Crown Prince Nayef bin Abdulaziz Al Saud in Riyadh, Saudi Arabia, Jan. 14, 2012.The premier said the decision to lift bilateral ties to an even higher level has shown the two nations' firm commitment to jointly face challenges and protect common interests as the world situation is undergoing profound changes.China would like to work with the Saudi side in deepening exchanges and cooperation in various aspects so as to benefit the two peoples and promote world peace and development, Wen added.He said the two sides should expand trade of crude oil and natural gas and energy-related cooperation as to deepen their energy partnership.Wen also asked the two countries to promote investment cooperation. The Chinese government encourages well-established Chinese companies to participate in Saudi Arabia's infrastructure construction such as railway, sea ports, electricity and telecommunications, he said.The two nations could also enhance security and law enforcement cooperation and promote people-to-people exchanges in areas like education and sports, as well as between the two nations' youths.Nayef said Saudi Arabia and China enjoy a time-honored history of exchanges, adding that the Saudi people have friendly feelings toward the Chinese people and expect even better bilateral ties.With joint efforts, bilateral ties have moved forward continuously with remarkable achievements in bilateral cooperation, he said, added that the partnership has bright prospects.Nayef said Saudi Arabia is willing to further boost political mutual trust with China, expand bilateral cooperation in economy and trade, energy, infrastructure, culture, press, and security, promote friendship between the two peoples, and lift bilateral ties to a higher level.Wen arrived here on Saturday evening after a short official visit to Nepal on the same day.

BEIJING, Dec. 24 (Xinhua) -- Renowned China economist Li Yining said Saturday that adjusting the structure of China's economy is a "matter of life and death" while the structure of GDP is more important than its size.The focus of the country's economic structure adjustment now should be transforming the dual structure in the urban and rural economy, which causes the widening income gaps between urban and rural residents, Li said at the China Economic Forum.He also noted that the key to stimulating domestic demand is to raise the workers' wages.With the external demand waned, the Chinese government has attempted to turn to domestic consumers to take up the slack. The country vows to expand domestic demand next year and increase residents' income, especially for disadvantaged groups.However, Li said raising household income is not enough and the government also needs to improve its social security system as well as increase construction of affordable houses and public rental houses.The country plans to begin construction or renovation on at least 7 million housing units for low-income groups next year, Minister of Housing and Urban-Rural Development Jiang Weixin said Friday.

WASHINGTON, Oct. 13 (Xinhua) -- In a trial that included about 35,000 men, those who were randomized to receive daily supplementation with vitamin E had a significantly increased risk of prostate cancer, according to a study published this week in the Journal of the American Medical Association.The study followed more than 35,533 men 50 or older at 427 sites in the United States, Canada and Puerto Rico. The men were divided into four groups who took daily doses of 400 international units of Vitamin E and 200 micrograms of selenium; Vitamin E and a placebo that looked like selenium; selenium and a placebo that looked like Vitamin E; or two placebos. The recommended daily intake of Vitamin E is about 22.4 international units.The researchers from the Cleveland Clinic found that the rate of prostate cancer detection was greater in all treatment groups when compared with placebo but was statistically significant only in the vitamin E alone group -- a 17 percent increased rate of prostate cancer detection. The difference in rates of prostate cancer between vitamin E and placebo became apparent during the participants' third year in the trial. The elevated risk estimate for vitamin E was consistent across both low- and high-grade disease."The observed 17 percent increase in prostate cancer incidence demonstrates the potential for seemingly innocuous yet biologically active substances such as vitamins to cause harm. The lack of benefit from dietary supplementation with vitamin E or other agents with respect to preventing common health conditions and cancers or improving overall survival, and their potential harm, underscore the need for consumers to be skeptical of health claims for unregulated over-the-counter products in the absence of strong evidence of benefit demonstrated in clinical trials," the researchers said.

COPENHAGEN, Nov.23 (Xinhua) -- Denmark's new tax on fatty foods is having little impact on consumer habits, an opinion poll showed Wednesday.Only seven percent of those polled said they had changed their shopping habits since the tax was imposed Oct.1, said FDB Analyse, which conducted the poll for Danish news agency Ritzau.The world's first fat tax affects products containing more than 2.3 percent saturated fat, meaning a kilo of saturated fat costs 16 Danish kroner (2.87 U.S. dollars).As a result, butter, cream, cheese, meat, cooking oil and processed foods like pizza and biscuits are among thousands of products that have become dearer in recent weeks.However, two out of three respondents to the poll said price rises are too low to make them alter their dietary habits, an opinion shared by some in the food retail sector."Price rises per product vary from a few oere to 2 kroner (0.36 U.S. dollar)," said Mogens Werge, Director of Consumer Policy at Coop, a supermarket chain which accounts for 40 percent trade in basic daily goods in Denmark."No Danes will change their dietary habits just because the cost of a packet of cookies rises by 35 oere," he told DR News, Denmark's public broadcaster.The Danish Agriculture and Food Council, an industry association, says the fat tax costs a Danish family with two children an additional 1,000 kroner (180 dollars), per year.Reacting to the poll, the Social Democratic Party (SDP), which leads Denmark's coalition center-left government, said the fat tax must be given more time to take effect."There are several parameters to measure the tax, one of which is purely economic, where you have to consider a longer time period," SDP consumer affairs spokesperson Mette Reissmann, told DR News."Also, I never thought we would suddenly become a nation that rejects fatty foods. It takes a long time to change consumer behavior," she added.The government's Commission on Prevention, tasked with finding ways to improve the nation's health, also said it is too early to evaluate the fat tax's impact. It believes the tax discourages purchase of unhealthy foods, and will help raise average Danish life expectancy by one week.For their part, two-thirds of poll respondents suggested the government would do better by removing value added tax (VAT) on healthy foods like fresh fruit and vegetables, and instead raise it on food products containing fat and sugar.Denmark already imposes 25 percent VAT on most consumer goods and food products.
