I haven't eaten since several hours. I eat a sugar cube and drink some water. How long will it take to reach my blood?

Instant, if you hold a sugar cube under your tongue

Are you diabetic?

No, I'm asking this because I'm taking a standardized test soon and there's a 10 min pause in the middle. That's why I'd like to know if the sugar can reach the blood quickly in order to bring more energy to the brain.

While doing some research I've found this: https://www.antenna.ch/en/activities/medicines/sublingual-sugar/

>Conclusion: in 50% of cases, sublingual sugar can restore a normal blood glucose level in under 20 minutes.
Looks like it could work in my case

You can just eat some fructose or acacia honey (which is high-fructose). Like maybe two full teaspoons of either. Fructose doesn't metabolize immediately, instead it will drip-drip-dribble into your bloodstream for two or three hours, as contrasted with glucose that gives you a spike of "YEAH! NOW I am like FELLING it!" - and then it's over. Sure, your sugar cube is half fructose. But that other half will be wasted in the first ten minutes of that second half of your test. It will just burn - and that is it.

Moreover, that glucose spike is likely to give you highly incorrect expectations of your mental capacity all the while you are in the middle of the test, so you could start getting serious WTF?s as it suddenly ceases, which will divert your attention from the test itself. I personally find going with fructose a MUCH smoother and more consistent sailing, even if its effects are significantly subtler, compared to the spike.

One last note: fructose doesn't kick in immediately, there is like 15-20min gap before it starts to properly drip in.

I think that's backwards. Look at the top-middle, where glucose/fructose turn into pyruvate (down). The step where glucose -> fructose is the slow, rate limiting step

Dunno. I am talking from my personal experiences (maybe shouldn't have included that metabolism part though). Take it or leave it.
