Myth: high-fructose corn syrup (HFCS) is making us fat

Since HFCS entered the American food supply in the 1970s, and the rates of obesity started to rise about then. Consequently, many blame HFCS for the fat plague. It’s true of course that the calories HFCS contributes can be linked to the nation’s obesity problems, but its calories are no different from those in refined white sugar: the makeup of HFCS (55 percent fructose and 45 percent glucose) is close to that of white sugar (50 percent fructose and 50 percent glucose), which means that our bodies digest HFCS and sugar in very similar ways. Nutritionally speaking, the two are virtually identical.

Interesting Fact: Coca Cola produced in Mexico is still made with sugar (as opposed to corn syrup in the US), and many people claim to be able to taste the difference – refusing to buy the “inferior” American coke. Unfortunately a truly scientific blind test has not been done and the various tests online all vary widely in their conclusions.

Fitness ‘lowers breast cancer risk’

Women who stay fit and physically active after the menopause can significantly reduce their risk of breast cancer, a study has shown.

But they have to work hard to get the benefit, spending more than seven hours a week taking “moderate-to-vigorous” exercise, say scientists.

“Light intensity” activities such as bowling, table tennis, fishing, slow walking and light gardening did not have the same effect. And no amount of exercise appeared to protect younger women during their fertile years.

Examples of “moderate-to-vigorous” activity given by the scientists included tennis, biking, swimming, weight-lifting, cheerleading, hiking, fast-walking, jogging and heavy housework and gardening.

Previous studies have linked physical activity and protection against breast cancer. But this was one of the first to look at the importance of different kinds of exercise at various stages of life.

Researchers asked more than 110,000 post-menopausal women to rate their activity levels at ages 15 to 18, 19 to 29, 35 to 39, and in the past 10 years.

Over a 6.6-year follow-up period, it was found that women in the last group who had done more than seven hours a week of moderate-to-vigorous exercise were 16% less likely to develop breast cancer than inactive women.

No link was seen between reduced breast cancer risk and physical activity at younger ages.

Light intensity exercise at any stage of life had no effect on the chances of developing breast cancer.

Breast cancer affects around 45,500 women each year in the UK and causes more than 12,400 deaths. An estimated one in nine women will suffer from the disease at some time in their life.

Does junk food at non-food stores add pounds?

A new study shows that candy, soda and other junk foods are commonly sold at stores not traditionally associated with food — in a trend that researchers say may be contributing to the U.S. obesity problem.

The study, of more than 1,000 non-food retail stores across the U.S., found that 41 percent sold candy, soft drinks, chips and other sweet and salty snacks. The foods were most commonly placed at check-out counters, where they were “within arm’s reach” of impulsive buyers, the researchers report in the American Journal of Public Health.

Nearly all drug stores and gas stations in the study sold snack foods — as did a majority of general merchandise stores, hardware and garden stores and automobile repair shops.

Even some stores selling clothes, books or furniture offered customers a snack selection.

The problem, the researchers contend, is that this “ubiquity” of snack foods may tempt many people into buying calories that they otherwise would not.

And over time, those calories could add up to extra pounds, write Dr. Thomas A. Farley and colleagues at Tulane University School of Public Health in New Orleans.

A number of studies, the researchers note, have found that when people grab snacks throughout the day, they typically do not compensate by eating less at meals.

“This suggests that calories consumed through impulse purchases of snack foods will increase total daily (calorie) intake and thus contribute to weight gain,” Farley and his colleagues write in their report.

They estimate that if a person sees snack foods at retail stores twice per week, and ends up buying a typical product only 10 percent of the time, that would mean an extra 2,600 calories in a year. That, in turn, could translate to close to a pound of weight gain per year.
