LOS ANGELES, April 11 (Xinhua) -- Drinking 100-percent fruit juice may offer disease-fighting benefits, a new study suggests.Fruit juice is linked with reduced risk of cancer, improved markers of heart health and cognitive decline, and increased antioxidant activity, according to the study published on Monday by the American Association for the Advancement of Science (AAAS).These protective health benefits are similar to those of whole fruits, said the study, conducted by researchers at the University of California, Davis.The researchers came to the conclusion after summarizing recent research data on the potential benefits of fruit juice. The review included a range of study types, from in vitro to clinical trials (60 papers total), all published in 2005 or later.Among the fruit juices included in the review, consumption of apple, citrus, cranberry, grape, and pomegranate juices all showed beneficial effects. Markers of improved health ranged from reductions in urinary tract infections (cranberry) to improvements in age-related cognitive decline (grape and apple) to reduced risk of prostate (pomegranate) and respiratory and digestive (orange, grapefruit) cancers. Additionally, intake of all juices was linked to heightened antioxidant activity."While it is universally accepted that fruit and vegetable intake is protective, there is not a clear consensus about the benefits of consuming the juices that are extracted from them," said study lead author Dianne Hyson, PhD. "An analysis of the scientific evidence suggests that 100 percent fruit juices retain important bioactive components that may promote good health and aid in disease prevention."

HARARE, Feb. 11 (Xinhua) -- Chinese Foreign Minister Yang Jiechi on Friday called on the West to lift sanctions they imposed on Zimbabwe while Zimbabwean President Robert Mugabe applauded the Asian giant for its continued political and economic support.Addressing journalists soon after meeting Zimbabwe President Mugabe, Yang, who is on a two-day visit, said Zimbabweans and other African people have a right to choose their own development path."We believe there should be the lifting of sanctions by certain countries. We think that is the voice of the Zimbabwean people and that is also the view of all the parties concerned here in Zimbabwe," Yang said, adding that no country has a right to dictate to another."We believe all nations should respect each others sovereignty and territorial integrity," he said."China believes that Africans have the right to choose their own way of development as they are the masters of the African continent. All others are just guests," he said.Yang said that China appreciates assistance from Africa and would also continue to reciprocate the support.Addressing the Chinese delegation earlier, Zimbabwean President Mugabe said the West continues to persecute Zimbabwe through sanctions for the decision the county took to empower its people through land.He said the imposition of sanctions was despite the fact that Zimbabwe and Britain had agreed that the former would redistribute the land while the latter would compensate affected farmers."The Western countries have imposed sanctions on us for taking our land although we had discussed this in 1979. That is what started the problem," Mugabe said.Mugabe said Britain had since turned to political reasons such as human rights, democracy and rule of law to justify continued sanctions imposed on Zimbabwe.He applauded continued cooperation between China and Zimbabwe which dates back to the struggle for independence.Meanwhile, China extended a 50 million yuan (7.5 million U.S. dollars) grant to Zimbabwe.Yang and his Zimbabwean counterpart Simbarashe Mumbengegwi signed the agreement on behalf of their countries.In his meeting with Mumbengegwi, Yang who described Zimbabwe as a "brother" said the two countries had identified areas for further cooperation such as infrastructure, agriculture, water conversation and personnel training.

BEIJING, March 11 (Xinhuanet) --Women who have a cup or more of coffee everyday may reduce their risk of stroke by as much as 25 percent, according to a new study in the Journal Stroke Thursday. This study, led by Swedish researcher Susanna Larsson of the Karolinska Institute in Stockholm, followed more than 34,000 Swedish women aged 49 to 83 who were free of heart disease. After 10-year of follow-up, there were 1,680 strokes, and the study found that those who drank at least one cup of coffee each day had a 22 to 25 percent lowered risk of stroke, compared with women who drank less.The study further suggested coffee can help prevent cognitive decline and can boost vision and heart health. It is also related to a reduced risk of liver cancer."We used to worry that (coffee) raises blood pressure and causes increased heart rate, but it appears to be less risky than we thought," said physician Claudette Brooks, spokesperson for the American Stroke Association. Now, exactly what it is about coffee that may lower stroke risk is unknown. But the researchers speculated that coffee might reduce inflammation, lower oxidative stress and help make the body more responsive to insulin.However, some experts kept skeptical about the real impact coffee would have on reducing the incidence of stroke."The problem with this type of study is that there are too many factors unaccounted for and association does not prove causality," Dr Larry B. Goldstein, director of the Duke Stroke Center at Duke University Medical Center said."Subjects were asked about their past coffee consumption in a questionnaire and then followed over time. There is no way to know if they changed their behavior," Goldstein added.In any case, the good news for coffee junkies is that at least drinking coffee don't increase women's risk of stroke.

CANBERRA, May 26 (Xinhua) -- Australian Health Minister Nicola Roxon on Thursday night said she will not be frightened off by the tobacco industry's attempt to lobby Malaysia to oppose the Australian government's proposal for plain packaging of cigarettes.According to ABC News, big tobacco companies have appointed a former United States ambassador to the World Trade Organization ( WTO), Peter Allgeier, to help them fight the Australian federal government's plain packaging plan, which is due to come into effect this year.An email sent to a Malaysian official and obtained by ABC News showed that Allgeier had a meeting with Malaysia's trade minister before, and he has been lobbying a Malaysian administrator to put pressure on Australia over plain packaging.Allgeier's email also stated that "members of the U.S. congress also have written to the Australian Government outlining concerns about the implications of plain packaging for the integrity of Australia's trade commitments."However, Roxon, who said she has not been approached by Malaysia on the issue, said Allgeier's appointment demonstrated just how far big tobacco is prepared to take its fight."But we won't be frightened off because big tobacco is hiring lobbyists or looking at ways to influence the action we're taking, " she told ABC television on Thursday night.The tobacco industry has already spent millions fighting plain packaging, and last year gave 5.2 million U.S. dollars to the Alliance of Australian Retailers (AAR) to fund an advertising campaign against the plan.If the cigarettes law is enforced, Australia will become the first country in the world to ban logos and brand names from cigarette packaging. Health warnings and the kind of graphic pictures will make up the majority of the packaging, while the rest of the packets will be plain olive green.
