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

然而，老年痴呆症患者大脑将体能量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.

甜香味尤是这种所散发出，它的学名是丙。

So, the more caffeine, the more ketones.

所以，咖啡因摄入越，产生的就越。

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

不仅如此，正如他在这里所展示的与对照组相比，老年痴呆症患者大脑摄取体的数量要更。

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

用于身体和大脑的能量，而不是依赖葡萄糖或碳水合物。

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，我们用甲乙来保持唱针的清洁。

And, they enhance the production of ketones.

提高的产生。

So here we have another ingredient that promotes ketones.

这里我们有另一种促进的成分。

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

链越短，越容易转类。

Babies may be living on ketones even before birth.

甚至在出生前，婴儿可能就靠过活。

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

研究发现“早餐时摄入的咖啡因会显著刺激的产生，并呈剂量依赖性。”

But lactation can also increase the production of ketones.

但是哺乳也会加剧类的产生。

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

在这三天内，他们会测量她血糖和水平。

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，当人体碳水合物摄入受限时体——人体内脂肪的代谢产物——便自然而然地成了大脑能量的新来源。

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合物，的产量会更高。

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

首先，咖啡中的咖啡因实际上有助于促进的产生，即使你没有进行低碳水合物饮食。

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

这暂时会起到用，但最终类只能够满足大脑所需能量的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，我们的身体可以适应他能量来源，如体，减少对碳水合物的依赖。

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.

牛津大学名誉教授学加斯·汉考克表示这是由于被称的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，体可以提供人体大脑所需能量的 60%。
