What are ultra-processed foods?
什么是“超加工食品”?
The term comes from a way of classifying food by how much industrial processing it has been through.
这个术语源自一种按照工业加工程度对食品进行分类的方式。
The lowest category is "unprocessed or minimally processed foods", which include: fruit, vegetables, milk, meat, legumes, grains such as rice, eggs.
第一类是“没有经过加工或加工程度最小的食品”，包括水果、蔬菜、牛奶、肉、豆类、大米等谷物和鸡蛋。

"Processed foods" have been altered to make them last longer or taste better - generally using salt, oil, sugar or fermentation.
加工食品是经过处理使其保质期更长或味道更佳的食品，通常加入盐、油、糖或采用发酵的方式。
This category includes: cheese, bacon, home-made bread, tinned fruit and vegetables, smoked fish, beer.
加工食品包括：奶酪、熏猪肉、自制的面包、罐头水果和蔬菜、熏鱼、啤酒。

Then come "ultra-processed foods", which have been through more substantial industrial processing and often have long ingredient lists on the packet, including added preservatives, sweeteners or color enhancers.
“超加工食品”则是经过更深度的工业加工的食品，通常包装上有长长的一列食品成分，包括防腐剂、甜味剂或色素。
Prof Maira Bes-Rastrollo, from the University of Navarra, told BBC News: "It is said that if a product contains more than five ingredients, it is probably ultra-processed."
西班牙那瓦拉公立大学的迈拉·贝斯-拉斯特罗略教授告诉BBC新闻说：“据称，如果一种产品含有五种以上的配料，那么这种产品很可能就属于超加工食品。”
Examples include: processed meat such as sausages and hamburgers, breakfast cereals or cereal bars, instant soups, sugary fizzy drinks, chicken nuggets, cake, chocolate, ice cream, mass-produced bread, many "ready to heat" meals such as pies and pizza, meal-replacement shakes.
超加工食品的例子有：香肠和汉堡等加工肉类、早餐麦片、谷物棒、速食汤、含糖气泡饮料、鸡块、蛋糕、巧克力、冰淇淋、量产面包、加热就能吃的馅饼和披萨等方便食品、代餐奶昔。

The first study, by the University of Navarra, in Spain, followed 19,899 people for a decade and assessed their diet every other year.
西班牙那瓦拉公立大学开展的第一项研究在十年内跟踪调查了19899人，每隔一年对他们的膳食进行评估。
There were 335 deaths during the study.
在研究期间有335人去世。
But for every 10 deaths among those eating the least ultra-processed food, there were 16 deaths among those eating the most (more than four portions a day).
研究发现，吃超加工食品最少的人和吃超加工食品最多(一天超过4份)的人死亡的比例是10比16。
The second study, by the University of Paris, followed 105,159 people for five years and assessed their diet twice a year.

It showed those eating more ultra-processed food had worse heart health.

Rates of cardiovascular disease were 277 per 100,000 people per year among those eating the most ultra-processed food, compared with 242 per 100,000 among those eating the least.
超加工食品吃得最多的人每年患心血管疾病的几率是10万分之277，而超加工食品吃得最少的人每年患心血管疾病的几率是10万分之242。
Dr Mathilde Touvier, from the University of Paris, told BBC News: "[The] evidence is accumulating.
