Chew it over: a guide to eating slowly | Life and style | The Guardian

Chew your deep-dish filled-crust pizza slowly. Slurp your thickshake with care. Do not pour cooking oil down your neck to act as a slide for your next Cinnabon.

Eat slowly. Get thin. This is the promise underlined by researchers at Japan’s Kyushu University, who pored over the data of 60,000 Japanese health insurance claimants. Slow eaters were 42% less likely to be overweight or obese than fast eaters. Even normal-speed eaters had a 29% lower risk of being overweight.

“It’s all to do with the signal to the brain,” explains performance nutritionist Elly Rees. “Studies show that it takes up to 20 minutes for us to register that we’re full. So people who overeat tend to eat too quickly.”

That 20-minute gap can be vast. If people eat more slowly they “find that they’re actually full,” Rees says.

How the Sugar Industry Shifted Blame to Fat

The sugar industry paid scientists in the 1960s to play down the link between sugar and heart disease and promote saturated fat as the culprit instead, newly released historical documents show.

The internal sugar industry documents, recently discovered by a researcher at the University of California, San Francisco, and published Monday in JAMA Internal Medicine, suggest that five decades of research into the role of nutrition and heart disease, including many of today’s dietary recommendations, may have been largely shaped by the sugar industry.

“They were able to derail the discussion about sugar for decades,” said Stanton Glantz, a professor of medicine at U.C.S.F. and an author of the JAMA Internal Medicine paper.

Early Puberty in Girls Is Becoming Epidemic and Getting Worse

Padded bras for kindergarteners with growing breasts to make them more comfortable? Sixteen percent of U.S. girls experiencing breast development by the age of 7? Thirty percent by the age of 8? Clearly something is affecting the hormones of U.S. girls—a phenomenon also seen in other developed countries. Girls in poorer countries seem to be spared—until they move to developed countries.

No scientists dispute that precocious or early-onset puberty is on the rise but they do not agree on the reasons. Is it bad diets and lack of exercise that cause growing obesity? Is it soft drinks themselves, even when not linked to obesity? Is it the common chemicals known as endocrine disrupters that exert estrogen-like effects (and also cause obesity)? Is it the many legal, unlabeled hormones used in the U.S. to fatten livestock? Some researchers even believe precocious puberty could be triggered by sociological factors like having no father in the home or even stress.

Junk food is tricking your brain: The depressing science behind your binging

Eating for the sake of pleasure, rather than survival, is nothing new. But only in the past several years have researchers come to understand deeply how certain foods—particularly fats and sweets—actually change brain chemistry in a way that drives some people to overconsume.

Scientists have a relatively new name for such cravings: hedonic hunger, a powerful desire for food in the absence of any need for it; the yearning we experience when our stomach is full but our brain is still ravenous. And a growing number of experts now argue that hedonic hunger is one of the primary contributors to surging obesity rates in developed countries worldwide, particularly in the U.S., where scrumptious desserts and mouthwatering junk foods are cheap and plentiful.

Overeating may be caused by a hormone deficiency, scientists say

It’s late at night and you really just want another slice of that chocolate cake — even though you’re not hungry.

Scientists say the phenomenon could be more than just having an overactive sweet tooth. It may be the result of a hormone deficiency in the brain, a discovery that could have implications for obesity down the road.
