However, the Alzheimer's brain has no problem using ketones for energy.

然而，老年痴呆症患者大脑将酮体作为其能来源却没有任何问题。

And the sweet smell is this particular ketone that is given out; it's called acetone.

甜香味尤其是这种酮所散发出，它学名是丙酮。

So, the more caffeine, the more ketones.

所以，咖啡因摄入越，产生酮就越。

Not only that, as he shows here, the Alzheimer's brain actually uptakes ketones better than controls.

不仅如此，正如他在这里所展与对照组相比，老年痴呆症患者大脑摄取酮体要更。

These ketones are used for energy in the body and brain rather than relying on glucose or carbohydrate.

酮用于身体和大脑能，而不是依赖葡萄糖或碳水化合物。

We use nitrogen to clean the lacquer, and we use methyl ethyl ketone to keep the stylus clean.

我们用氮气来清洁漆，我们用甲乙酮来保持唱针清洁。

And, they enhance the production of ketones.

提高酮产生。

So here we have another ingredient that promotes ketones.

这里我们有另一种促进酮成分。

The shorter the chain, the easier it turns into ketones.

链越短，越容易转化为酮类。

Babies may be living on ketones even before birth.

甚至在出生前，婴儿可能就靠酮过活。

They found that " Caffeine given at breakfast significantly stimulated ketone production in a dose-dependent manner."

研究发现“早餐时摄入咖啡因会显著刺激酮产生，并呈剂依赖性。”

But lactation can also increase the production of ketones.

但是哺乳也会加剧酮类产生。

Over these 3 days, they will monitor her blood sugar and ketones.

在这三天内，他们会测她血糖和酮水平。

Very simply put, ketones are a source of energy naturally produced in the body from fat when dietary carbohydrate is restricted enough.

简而言之，当人体碳水化合物摄入受限时酮体——人体内脂肪代谢产物——便自然而然地成了大脑能新来源。

We can expect that ketone production would have been even higher if they had the caffeine without carbohydrate.

我们可以预期，如果他们只摄入咖啡因而不摄入碳水化合物，酮产会更高。

First, the caffeine in the coffee actually helps to boost ketone production, even if you're not doing a low-carb diet.

首先，咖啡中咖啡因实际上有助于促进酮产生，即使你没有进行低碳水化合物饮食。

This works for the time being, but ultimately only 75% of the brain's energy requirements can come from ketones. It still needs glucose!

这暂时会起到作用，但最终酮类只能够满足大脑所需能75%，它仍然需要葡萄糖！

Some research suggest that our bodies can adapt to other energy sources like ketone bodies and be less reliant on carbs.

一些研究表明，我们身体可以适应其他能来源，如酮体，减少对碳水化合物依赖。

Oxford University Emeritus Professor of Chemistry Gus Hancock says it is due to the build-up of chemicals called ketones in the patient's blood.

牛津大学名誉教授化学加斯·汉考克表这是由于被称为酮化学物质在病人血液中累积所致。

And it has been shown that ketones can provide up to 60% of the energy requirements for an adult brain.

研究表明，酮体可以提供人体大脑所需能 60%。
