Jamie Oliver seeks million signatures on obesity petition@SCMP


British television chef Jamie Oliver has set up a global petition fighting for practical food education for every child in the world and needs your help to reach one million signatures. This comes ahead of his annual Food Revolution Day on Friday. Oliver (pictured) plans to take the petition to the G20 Leaders’ Summit in Turkey in November and present it to the governments represented there. “We’re currently facing a global obesity epidemic, with 42 million children under the age of five either overweight or obese across the world. The bottom line is the next generation will live shorter lives than their parents if nothing is done to rectify these alarming stats,” says Oliver on his petition page at change.org/jamieoliver.
“It’s essential that we arm future generations with the life skills they urgently need in order to lead healthier, happier, more productive lives. I passionately believe this is every child’s human right, and I hope you agree.”
Parents often fail to see their children as obese
Although rates of childhood obesity have risen over the past several decades, a vast majority of parents misperceive their children as “about the right weight”, according to new research led by New York University’s Langone Medical Centre. Published online in the journal Childhood Obesity, the study analysed data from the US National Health and Nutrition Examination Survey. They studied nearly 7,000 children over two time periods, 1988-94 and 2007-12. The children in the second time period were significantly more overweight than the children in the first period.
Parents were asked whether they considered their children, aged two to five years, to be overweight, underweight, or just about the right weight. Nearly all parents of overweight boys from the first period perceived their sons as “about the right weight” (97 per cent), with a very similar result from the second period (95 per cent). About 88 per cent in the first period perceived their daughters as “about the right weight” and 93 per cent in the second period.

Late-night snacking: is it your brain’s fault?

A new study has revealed that images of food, especially high-calorie food, can generate spikes in brain activity, but those neural responses are lower in the evening. And because there’s lower reward-related brain reactivity to food images in the evening, the researchers at Brigham Young University in the US state of Utah suggest this leads people to eat more at night to try to become satisfied. In the study, which appears in Brain Imaging and Behaviour, functional MRIs were used to monitor the brain activity of study subjects while they viewed images of both low- and high-calorie foods.

肥胖和超重 Obesity and overweight


  • 自1980年以來,全球肥胖人數已翻了一番。
  • 根據2008年的統計,20歲或以上的成年人口中,有15億人屬於超重。其中超過2億男性及接近3億的女性屬於癡肥。
  • 65%的世界人口居住的國家,因超重和癡肥以死亡的人數比體重不足為高。
  • 根據2010年的數據,接近4300萬名5歲以下的兒童屬於超重。
  • 癡肥是可以預防的。

Key facts

  • Worldwide obesity has more than doubled since 1980.
  • In 2008, 1.5 billion adults, 20 and older, were overweight. Of these over 200 million men and nearly 300 million women were obese.
  • 65% of the world’s population live in countries where overweight and obesity kills more people than underweight.
  • Nearly 43 million children under the age of five were overweight in 2010.
  • Obesity is preventable.

引致超重及癡肥最基本的原因是卡路里(熱量) 的吸收與消粍的不平衡。全球生活模式偏向於:吸收更多高能量,即脂肪、鹽、糖含量高的食物,相對地,含維他命、礦物及其他微量營養素則缺乏吸收。而涉及運動的活動愈來愈少,因為工作多是坐著的工作,交通運輸愈來愈普及,全球都市化的加速亦是原因之一。

What causes obesity and overweight?
The fundamental cause of obesity and overweight is an energy imbalance between calories consumed and calories expended. Globally, there has been:
an increased intake of energy-dense foods that are high in fat, salt and sugars but low in vitamins, minerals and other micronutrients; and
a decrease in physical activity due to the increasingly sedentary nature of many forms of work, changing modes of transportation, and increasing urbanization.


What are common health consequences of overweight and obesity?
Childhood obesity is associated with a higher chance of obesity, premature death and disability in adulthood. But in addition to increased future risks, obese children experience breathing difficulties, increased risk of fractures, hypertension, early markers of cardiovascular disease, insulin resistance and psychological effects.



Facing a double burden of disease
Many low and middle-income countries are now facing a “double burden” of disease. While they continue to deal with the problems of infectious disease and under-nutrition, they are experiencing a rapid upsurge in incommunicable disease risk factors such as obesity and overweight, particularly in urban settings.

It is not uncommon to find under-nutrition and obesity existing side-by-side within the same country, the same community and the same household. Children in low- and middle-income countries are more vulnerable to inadequate pre-natal, infant and young child nutrition. At the same time, they are exposed to high-fat, high-sugar, high-salt, energy-dense, micronutrient-poor foods, which tend to be lower in cost. These dietary patterns in conjunction with low levels of physical activity, result in sharp increases in childhood obesity while under-nutrition issues remain unsolved.
