每日英語跟讀 Ep.847: About scientific research - Certain Junk Foods Could Be Messing With Your Brain’s Appetite Control, Study Finds

Emerging evidence in humans suggests a typically Western high-fat, high-sugar ’junk food’ diet can quickly undermine your brain’s appetite control.


After indulging in a week-long binge of waffles, milkshakes and similarly rich foods, researchers in Australia found young and healthy volunteers scored worse on memory tests and experienced a greater desire to eat junk food, even when they were already full.


The findings suggest something is amiss in the hippocampus - a region of the brain that supports memory and helps to regulate appetite. When we are full, the hippocampus is thought to quieten down our memories of delicious food, thereby reducing our appetite.


When it’s disrupted, this control can be seriously undermined.


Over the years, extensive research on juvenile mice has found the function of the hippocampus is very sensitive to ’junk food’ , but this has only recently been observed in young and healthy humans.

Squatting or kneeling is better for your posture than sitting all day, anthropologists claim 人類學家:蹲姿或跪姿比坐一整天來得好

Resting postures such as squatting or kneeling may be better for health because they require more muscle activity than sitting on a chair, researchers claim.


The findings are based on data gathered from a hunter-gatherer population in Tanzania who wore devices that measured physical activity as well as periods of rest.


Anthropologists from the US found that despite being sedentary for almost 10 hours each day, equivalent to clocking a shift in the office at the desk, the Hazda people appeared to lack the markers of chronic diseases associated with long periods of sitting.


They believe this is down to the ‘active rest postures’ used by the tribe.
