(WAToday) - MANY believe a glass or two of wine is good for them, with its antioxidants working to protect the heart. But if you are carrying extra weight, drinking has no protective effect, new research has found. An obesity expert from London, Tim Lobstein, said findings that small amounts of alcohol lowered the risk of heart disease were taken from surveys more than 40 years old. ''We were concerned that the findings may not apply to our modern, fatter population,'' said Dr Lobstein, an adjunct professor at Curtin University's Public Health Advocacy Institute in Perth.
