羡慕嫉妒恨：随心所欲吃也不胖的秘密(双语)

Foods that make some of us put on weight can have little effect on others, according to research being carried out in Israel. It might be time to rethink the way we diet, writes Dr Saleyha Ashan.


　　据以色列进行的一项研究，让一些人长胖的食物，可能对另一些人没有丝毫影响。Saleyha Ashan博士说，也许是时候重新思考我们的饮食方式了。


　　Like most of the population, I must admit that I am on an eternal quest to lose weight. For me it’s more to do with concerns about health than aesthetics. I have polycystic ovary syndrome and a family history of type 2 diabetes and that puts me into a high risk category for developing diabetes myself.


　　和大多数人一样，我必须得承认，减肥是我的永恒不变的追求。当然对我来说，我更关心的是健康，而不是曲线美。我患有多囊卵巢综合症和2型糖尿病家族史，使得我成为易患糖尿病的高危人群。


　　I have always watched what I eat - and yet I never seem to shift the weight, while friends seem to eat what they want without putting on a single bulge. It seemed like they could just "break all the rules". But perhaps that’s just because we have been wrong about what "the rules" of diets are.


　　我一直很注意我的饮食，但我从来没有减肥成功过；而我的朋友们似乎总是随心所欲的吃，却不怎么长胖。看起来他们貌似能“打破所有的规则”，但这也许恰恰证明了：我们一直以来所信奉的饮食“规则”本身就是错的。


　　Last month, I travelled to Israel for Trust Me, I’m a Doctor to take part in a vast new research study being carried out there by a team at the Weizmann Institute of Science. They are in the process of monitoring 1,000 people in absolutely minute detail to see exactly how their bodies react to food - and their first results are rewriting the textbooks on our relationship with food.


　　上个月，我去以色列参加“相信我，我是一个医生”的研究，该研究由魏茨曼科学研究所的一个团队进行。为了分析人们的身体对食物有怎样的反应，他们对1000人进行监控，精确到每一分钟——而他们的第一个研究结果就重写了教科书中我们与食物的关系。


　　When we eat, our blood sugar level rises - and both the speed at which it peaks, and then how quickly our bodies deal with that and get it back to normal, is very important to our health.


　　当我们吃东西时，血糖上升——当速度达到峰值时，身体的反应速度、以及多久能恢复到正常，对我们的健康来说是非常重要的。


　　Foods have, therefore, been traditionally classified by how much of a blood sugar spike they cause - with "high GI" (Glycaemic Index) foods being thought of as bad for us, and "low GI" as good. Every nutritionist would tell you this. But the Israeli research, led by Dr Eran Segal and Dr Eran Elinav, suggests that it is simply not so.


　　因此，依据会引起血糖升高的多少，食物在传统上被划分为对身体有害的“高GI（血糖指数）”食物和有益的“低GI”食物。每一个营养师都会这样告诉你。但是由 Eran Segal 和 Eran Elinav博士带领的以色列研究团队表示，并不是这么简单。


　　Once I arrived in Tel Aviv, the team not only took all my vital statistics and medical history, but they gave me a little implanted glucose monitor under my skin, which would monitor my blood sugar levels constantly for the next week. The team’s nutritional experts had prepared me six days of menus specifically designed to test my body’s response to a few standardised meals, mixed in with some of my personal staple foods.


　　当我到达特拉维夫后，这个团队不仅将我所有的重要数据和既往病史备案，他们还在我的皮肤下植入了一个小小的葡萄糖监测器，它将在接下来的一周里持续监测我的血糖水平。这个团队的营养专家已经为我准备好了六天的菜单，他们将一些标准化的食物和我个人的主食混合，专门用来测试我的身体的反应。


　　I’m an accident & emergency doctor, which is something that undoubtedly has an effect on my diet.


　　我是一个急救医生，这毫无疑问会对我的饮食产生影响。


　　I never buy bread - it’s an aisle I just don’t even go down in the supermarkets and I live in fear of sandwiches - but I see other people living on them.


　　我从来不买面包吃——我在超市里从来都不会去那一排货架，我也不喜欢吃三明治，但我看到很多人简直以吃面包和三明治为生。


　　I do, however, reach for the grapes - I love them. I can eat bunches of them and feel guilt-free doing so. They are my go to "healthy" snack. Another guilt-free grab is sushi. I snatch a box of salmon nigiri and am off. Now, though, had come my chance to find out what each of these foods was really doing to my body.


　　然而，我很喜欢吃葡萄。我可以吃一口气吃很多串葡萄，并且没有负罪感。它是我的“健康”小吃。另一个无负罪感的小吃是寿司。我可以很快消灭一盒子三文鱼寿司。不过，现在我终于有机会了解这些食物会对我的身体产生什么影响。


　　Other things, such as stress levels, exercise and sleep can all affect our blood glucose responses, so the research team made me log everything I did throughout the day on a little phone app.


　　其他因素，比如压力水平、锻炼程度和睡眠质量都会影响我们的血糖反应，所以研究小组让我每天都在一个手机APP上记录下所有的事情。


　　Most importantly, though, because their initial data had suggested that different individuals res
