Wine for Your Heart?  Think Again

first_img“Any heart gains from drinking alcohol in moderation are likely outweighed by the harm, say researchers.”  That’s how a story on BBC News begins that warns that alleged benefits of alcohol for heart health may not be trustworthy.  A New Zealand team investigated earlier scientific studies that purported to show benefits of drinking in moderation, and found that “the way the studies were carried out did not allow the researchers to be able to say with certainty that the findings could not due to other factors rather than solely the amount of alcohol consumed.”  This did not mean that health benefits have been falsified – only unconfirmed.  Meanwhile, the known harms of alcohol may outweigh any benefits.  “If so, the public health message is clear,” the article warns.  “Do not assume there is a window in which the health benefits of alcohol are greater than the harms – there is probably no free lunch.”  One theory keeps getting more and better confirmation, though: exercise is good for the heart.  See the latest example on EurekAlert.The science is inconclusive that there are any coronary benefits to alcohol consumption, but the harms are well known.  It may just be that alcoholics tend to have clean arteries.  There are two lessons in articles like this: (1) much of what we think we know is wrong, and (2) scientific findings are tentative.  The assumption that wine is healthy has been going around since the 1960s and 1970s.  How many people have been led to believe that they should drink wine more often for good health?  How many following that line got drawn into alcoholism, or swamped any gains with greater harms?  This is not to take a hard-line position on who is right, but just to remind everyone that some claims by scientists may be based on flawed studies.    If you choose to drink during the holidays, don’t claim you do it for health reasons.  The last sentence in the article makes the best sense: “Our advice remains the same – the best way to reduce the risk of heart disease is to quit smoking if you smoke, increase levels of physical activity and eat a healthy balanced diet.”    A reader pointed out that it is not the alcohol, but the antioxidants, that confer upon wine its healthy benefits.  But consumers can find equal or better antioxidants in pomegranates, dark chocolate and many other non-alcoholic foods and drinks.  It would seem most drinkers primarily want the taste of the alcohol, or else there would be a large market for non-alcoholic wine among health-conscious consumers who want the antioxidants without the harm of ethyl alcohol.  Wine consumption still cannot be rationalized, therefore, on claims it is good for the heart.(Visited 16 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Study Finds No Direct Link Between Wind Turbines and Health Problems

first_imgA study of more than 1,200 adults in two Canadian provinces has found no definitive connection between the noise from utility-scale wind turbines and a number of chronic health problems, according to published reports.The study by Health Canada and Statistics Canada focused on people living in Ontario and Prince Edward Island in the vicinity of turbine installations. The study was launched in 2012 after groups fighting the development of wind farms said turbines were making people ill, said an article posted at the website of The Toronto Star.On November 6, results of the $2.1 million study were released. While the panel said that turbines could be annoying for a number of reasons — including the noise made by the turning rotor blades, the aircraft warning lights on top of the turbines, and the way the moving blades cause shadows to flicker — there were no definitive connections to poor health and disease.Still, the report says the findings are not conclusive. Wind opponents also claim victoryWhile wind opponents didn’t get the smoking gun they were looking for, they also found something to like in the report. According to The Star, Eric Gillespie, a Toronto lawyer representing wind farm opponents, said the report was a “breakthrough.”“It confirms what appear to be serious adverse health effects,” he told the newspaper. “It’s coming from the national health regulator.”Gillespie is currently representing a town on Lake Huron that is opposing two wind farms before an environmental review panel. He said the Health Canada study would be a boost to his clients.““It would be very difficult to argue that effects on blood pressure, migraines, ringing of the ears, dizziness, sleep and stress issues — that one or more of (these) is not a serious health impact,” The Star quotes Gillespie as saying. “This study finds that those are statistically significantly related to wind turbine noise and annoyance.”The Canadian Wind Energy Association looked at the results through opposite end of the telescope.Noting the study found “no evidence of a causal relationship” between turbine noise and medical issues, association president Robert Hornung said in a press release: “The balance of scientific evidence to date continues to show that properly sited wind turbines are not harmful to human health and that wind energy remains one of the safest and environmentally friendly forms of electricity generation.” Results are of potential interest elsewhereAs the number of wind farms goes up, so do complaints from nearby residents. Some residents report leaving their homes because of turbine-induced problems, and a number of lawsuits have been filed by opponents.Neither the Centers for Disease Control and Prevention nor the World Health Organization recognizes wind turbines as a documented source of health problems.A county health board in Wisconsin last month declared a small wind farm near Green Bay a public health risk. County officials told a local newspaper recent studies made a connection between low-frequency turbine noise and poor health.But the specifics of the studies weren’t shared, and county officials have not returned calls asking for more details.Separately, the Wisconsin Wind Siting Council in October sent a report to state legislators summarizing recent scientific findings on health implications of turbines. The council didn’t conduct any research itself, but looked at what others had found between 2011 and 2014.The panel concluded some people living near turbines “may experience annoyance and a small fraction report sleep disturbance” due to turbine noise. Some people also report increased stress, the council said, and stress and sleep disturbance may be related to chronic health conditions.The council also found people who have negative feelings about wind energy are more likely to report health problems. A majority of people living near turbines “do not report stress, sleep deprivation, or chronic adverse health effects attitude to wind turbines,” the council wrote.The council recommended no changes in current state law.center_img No links to self-reported or measured health issuesResearchers selected all homes within 600 meters of one of the 399 turbines included in the study, plus a random selection of houses between 600 meters and 10 kilometers from the turbines. One adult from each of 1,293 participating households took part, answering questions in person and submitting to tests of blood pressure, sleep quality, and hair cortisol (a biomarker for stress).Houses were grouped into different categories of wind turbine noise, ranging from less than 25 decibels (dB) to more than 40 dB.When it came to results of self-reported health problems, the study found no connection between wind turbine noise and sleep disturbance, health issues such as dizziness, migraine headaches or tinnitus, chronic problems like heart disease, diabetes or high blood pressure, or high stress. Results of measured tests were the same.But the more turbine noise, the more people became annoyed, the report says, and annoyance is not a trivial problem.“Statistically significant exposure-response relationships were found between increasing WTN [wind turbine noise] levels and the prevalence of reporting high annoyance,” the report says. “These associations were found with annoyance due to noise, vibrations, blinking lights, shadow and visual impacts from wind turbines. In all cases, annoyance increased with increasing exposure to WTN levels.”While researchers found the closer and louder the turbines, the more likely people were to be annoyed, if study subjects were personally benefiting from the turbines — getting rent, for example — the annoyance levels were “significantly lower.”The study notes that annoyance is “statistically related” to several self-reported health problems, such as high blood pressure, migraines, and dizziness, and can be linked to measured hair cortisol and blood pressure.“Although Health Canada has no way of knowing whether these conditions may have either pre-dated, and/or are possibly exacerbated by, exposure to wind turbines, the findings support a potential link between long term high annoyance and health,” the report says. “Findings suggest that health and well-being effects may be partially related to activities that influence community annoyance, over and above exposure to wind turbines.”last_img read more

The Embassy of Japan is partnering with the Government and Woman Incorporated to refurbish a transition house for female victims and survivors of gender-based violence.A $14-million contract, funded under the Grant Assistance for Grassroots Human Security Projects of Japan, was signed on February 27 by Japanese Ambassador to Jamaica, His Excellency Hiromasa Yamazaki; and Gender Specialist and Acting Executive Director of Woman Inc., Joyce Hewett.The Woman Inc. project, with support from the Bureau of Gender Affairs (BGA), an agency of the Ministry of Culture, Gender, Entertainment and Sport, will involve the renovation of a 30-year-old building to a transition house. Female residents at the facility will be able to attend skills training classes to prepare them to be independent.Speaking at the signing ceremony, held in the boardroom of the Public Broadcasting Corporation of Jamaica, 5-9 South Odeon Avenue in Kingston, Ambassador Yamazaki said Japan is pleased to provide financial assistance to address the issue of gender-based violence in Jamaica.He said that the main objective of Japan’s development cooperation is human security, which is a concept that “pursues the right of individuals to live happily and in dignity, free from fear and to ensure their protection and empowerment”.The Ambassador noted that Japan will be introducing an empowerment initiative for women at the upcoming World Assembly for Woman (WAW!) 2019 in Tokyo next month.“We expect to promote the movement of enhancing women’s empowerment in the world. We strongly believe that gender equality and promoting women’s empowerment are essential for realising quality growth,” he said.Ambassador Yamazaki said Japan is fully committed to fostering closer ties with Jamaica.“Many of you may already know that 55 years ago, Japan and Jamaica established diplomatic relations and our friendly partnership started,” he added.The Ambassador commended the Ministry of Culture, Gender, Entertainment and Sport, Woman Inc., civil society and other stakeholders for forming partnerships to address gender-based issues in the country.Meanwhile, Director of Policy and Research (Acting) at the Bureau of Gender Affairs, Kristal Tucker Clarke, said that victims of abuse will be able to stay a longer time at the transition home, noting that persons are only able to stay for temporary periods (no longer than three months) at emergency shelters.She said the partnership resulted from a courtesy call involving officials of the Embassy of Japan and the Minister of Culture, Gender, Entertainment and Sport, Hon. Olivia Grange, when the Minister requested support in the matter of gender-based violence.Mrs. Tucker Clarke thanked the Government and people of Japan for accepting the proposal to fund the project, and the BGA for providing technical assistance for the application of the grant.She also commended former Japan International Cooperation Agency volunteer at the BGA, Mia Akita, who provided guidance through the application process.

Several Schools to be Removed from Shift System

first_imgMONTEGO BAY: Some 10 to 15 schools are to be taken off shifts this year, as the Ministry of Education looks to eliminate the system being used by some 200 institutions to accommodate their large populations.Portfolio Minister, Hon. Rev. Ronald Thwaites, who made the announcement as he addressed an Education Summit at the University of the West Indies’ (UWI) Western Jamaica campus in St. James on Friday, June 7, said that the aim is to “do progressively more year after year.”He informed that some 90,000 new secondary school places are needed and the Ministry is looking at ways to satisfy the needs including forging partnerships.He issued an appeal for anyone with knowledge of any available space “which can be transformed into a school come and tell me because we are going to have to use it”.Meanwhile, as the Ministry focuses on providing education and training to meet workforce needs, Rev. Thwaites informed that the HEART Trust/NTA has been asked to upgrade the technical and vocational facilities in the high schools, so that they can offer certified training in those areas.He stated that by 2016, all high school graduates must be qualified either academically or with at least one marketable skill.“By 2016, we expect that there is going to be no more issue of a person attending a high school and at the end of the day, coming out with a certificate of attendance, and a picture in your cap and gown meaning nothing,” Rev. Thwaites stated.“You must take an examination, which will be a combination of CSEC (Caribbean Secondary Education Certificate) or CVQ(Caribbean Vocational Qualification), whatever combination suits your aptitude, and you must come out with at least one marketable skill, so that you can apply for work or you can go on to other advanced technical training,” he stated.Contact: Bryan Millerlast_img read more
