The article by Robert Bridge, quoted and linked to inside, speculates on obesity being a factor in the United States' poor performance in the PyeongChang olympic games. It includes a graph of order of obesity in OECD countries. Australia is the fifth highest obesity country. Japan is the lowest. My money is on high fructose additions to our diets, such as corn-syrup. Dr Lustig University of California San Francisco, Division of Pediatric Endocrinology, has been putting this message out for some time in fascinating scientific videos, including, "Fat Chance" and "The skinny on obesity." I have embedded "Fat chance" in the quoted material from the article inside.
I don’t have kids but I am disturbed about the Heart Foundation’s Active Healthy Kids very poor report card for Australian children last week. It said that Australian children are largely unfit because of a lack of exercise and that this deterioration has happened in the last couple of decades. Natasha Schranz author of the Foundation's inaugural report has graded Australian children at a disgraceful D minus. Contributing to this terrble score was a D for "active transport", meaning not nearly enough walking or bicycle riding to and from school.
