如果每天一包薯片，會(huì)發(fā)生什么?

據(jù)英國(guó)《泰晤士報(bào)》報(bào)道，如果每天多吃一包薯片，一年后體重將增加約6.4公斤。

People drastically underestimate the number of calories in their snacks, with experts warning that eating a bag of crisps every day could lead to a stone of weight gain in a year.

stone：英石(英國(guó)重量單位，相當(dāng)于6.35千克或14磅)

英國(guó)慈善機(jī)構(gòu)Nesta的一份報(bào)告顯示，在2000名受訪者中，約3/4的人低估了小幅減少的熱量攝入對(duì)體重的影響。

A survey of around 2,000 adults found that around three quarters underestimated the impact of a small reduction could have. One in ten believed that cutting 200 calories a day would not affect weight.

同時(shí)，很多人似乎并不清楚自己吃的零食中到底有多少熱量。

根據(jù)Opinium發(fā)布的一項(xiàng)調(diào)查，盡管受訪者對(duì)于自己所吃主食的熱量含量估計(jì)基本正確，但他們對(duì)于零食中熱量的估計(jì)值卻與正確值相去甚遠(yuǎn)。

When it came to snacks, people struggled, with 95 percent guessing that half a sharing bag of tortilla chips had 214 calories on average, almost half the true figure of 447.

人們很難對(duì)零食中所含熱量做出正確的估算。95%的受訪者認(rèn)為半袋油炸玉米片含有214卡路里熱量。但實(shí)際上，這個(gè)估算值連實(shí)際值447的一半都不到。

報(bào)道還指出，零食在英國(guó)家庭飲食中的占比逐年走高，疫情導(dǎo)致的封鎖讓民眾攝入了更多的零食。

Nesta健康團(tuán)隊(duì)的負(fù)責(zé)人Hugo Harper表示，我們不應(yīng)該把抵擋高熱量零食誘惑的壓力都給到消費(fèi)者，我們的“食物環(huán)境”也需要做出改變。

He said, "Our environment has a real impact on what we eat, from adverts and supermarket promotions to what's available in our local corner shop.

他說(shuō)：“周圍環(huán)境實(shí)實(shí)在在地影響著我們的飲食，這些包括食品廣告、超市促銷活動(dòng)、附近超市出售的食物等�！�

"If we had fewer cues to snack, or were pushed to buy fewer high calorie snacks, we should be able to see real change."

“如果沒有那么多東西誘導(dǎo)我們買零食，少一些高熱量零食的推銷，我們應(yīng)該能看到很大的變化。”

今年十月，英國(guó)將執(zhí)行新的規(guī)定來(lái)構(gòu)建一個(gè)更加健康的“食物環(huán)境”，禁止大型超市對(duì)高糖高脂高鹽的食物進(jìn)行促銷活動(dòng)。

New rules coming into force in October will restrict promotions on foods high in fat, sugar and salt in big shops.

超重、肥胖，標(biāo)準(zhǔn)到底是什么?

在中國(guó)，“管住嘴、邁開腿”也是一個(gè)值得關(guān)注的話題——我國(guó)有超一半的成年人超重或肥胖。那么，胖不胖到底怎么衡量呢?

❶ 身體質(zhì)量指數(shù)(BMI)

身體質(zhì)量指數(shù)(body mass index)是衡量你是否超重或肥胖的有效指標(biāo)。它的計(jì)算方式為體重(kg)除以身高(m)的平方。

Body mass index (BMI) is a simple index of weight-for-height that is commonly used to classify overweight and obesity in adults. It is defined as a person's weight in kilograms divided by the square of his height in meters (kg/m2).
