澳洲我已经停止购买孩子的节食可乐和酸奶。这是他们对您的记忆的灾难性隐藏副作用：Rob Galloway博士

甜味剂无处不在。在饮食可乐，无糖酸奶，咀嚼口香糖中 - 即使在您没想到的东西中，例如调味料和药物。多年以来，信息一直很简单：它们是安全的，比糖更健康，并且可以帮助减肥。

像许多人一样，我曾经以为甜味剂的主要偏低效果很小，这可能很小。 class="mol-para-with-font">But recent research has raised concerns about them, suggesting they can reduce insulin sensitivity – which means your body is less able to deal with sugar in the blood, so rather than helping with weight control, they could undermine it.

However, what was once a vague anxiety in my mind about sweeteners has become a determination to get rid of them from my family’s diet.

And that is because of a study published in the journal Neurology this month which made me look at sweeteners in a completely different light.

Researchers monitored the diets of more than 12,700 adults in Brazil, specifically how much low-calorie and no-calorie sweetener they consumed.他们还测试了参与者四年后的记忆和大脑功能。

结果令人震惊。在60岁以下的成年人中，经常食用甜味剂的人的记忆力和思维技能降低了速度。效果等同于他们在八年中逐渐衰老的大脑。

Those who regularly consumed sweeteners, such as those in diet sodas, experienced a faster decline in memory and thinking skills

Amongst the over-60s, the pattern was similar. However, the data wasn’t strong enough to show conclusively the link with sweeteners.

The results were even worse in the people with diabetes: sweetener users had about a 30 per cent higher risk of memory decline.

For me, that’s it: I’m now trying to avoid sweeteners altogether, including not drinking any diet drinks (or全脂版本 - 当您专注于未添加的内容时，您可以学会爱水）。

当然，甜味剂行业并没有把这个躺下来。贸易机构已经退缩了，认为这项研究是“观察性的”，因此无法证明甜味剂引起了这些问题。

在他们的其他论点中，他们指出，全球卫生机构，包括英国，欧盟和我们在内 some of their points are technical, about how the research was done.

So let me focus on a key complaint about the new research: that the study is only observational, it didn’t prove that sweeteners caused memory decline.

But to prove sweeteners were the cause we’d have to give some people sweeteners for decades, then compare them with people who didn’t有他们。这根本是不可能的 - 如果您正在调查可能造成伤害的事物。

就像吸烟一样。从来没有一个试验，一半的人口吸烟了多年，然后与没有吸烟的人相比。取而代之的是，我们依靠观察性研究来确定吸烟是有害的。

数十年来，烟草业隐藏在这条线后面，这只显示了“关联，而不是因果关系”。但是有一个转折点。

营养科学以相同的方式工作：当协会强大并且在各组人之间重复时，并且在生物学上可以合理的话，因为它与甜味剂相当 - 就像甜味剂一样 - 它是一个警告信号，我们在我们的风险中无视。但是这些决定是基于毒理学和关于消化和排泄的短期研究，而不是基于认知能力下降等长期结果。缺乏有关大脑健康的证据是SI很少，因为没有人看过。这项研究填补了该空白。

那么，为什么甜味剂会影响大脑呢？一条路线是通过肠道微生物组。在小鼠和人类中的研究都表明，诸如糖精和三氯蔗糖等甜味剂可以改变肠道细菌的平衡。

Those changes, in turn, affect how we handle glucose.

One landmark trial, published in the journal Nature in 2014, showed that healthy volunteers who were given saccharin developed poorer blood-sugar control within just a week.

Sweeteners may also interfere directly with insulin sensitivity – studies show they can lead to higher insulin levels, which causes increased fat storage.

That’s why we haven’t seen a reduction in obesity despite diet drinks becoming more popular over the past few years.

And we know that, over time, high insulin levels can damage blood vessels in the brain, reduce energy supply to neurons, and accelerate the kind of changes we see in痴呆症。

甜味剂也提供了无卡路里的强烈甜味。这种不匹配似乎使大脑的信号系统混淆，使我们对糖的食欲开启。

对动物的研究表明，这些途径的长期过度激活与大脑的化学招待员的变化有关，影响了记忆，情绪和脑子的脑子。功能，例如炎症。

，尽管这些证据中的每一个都可能不够，但它们共同构建一张图片：甜味剂改变了代谢，肠道健康和脑化学的化学，我们知道与痴呆症相关。这就是科学家在谈论生物学合理性时的意思。
