Does anyone out there have any experience with dextrose tablets? I found
these at a small bakery in town here the other day and I've been thinking of picking up a small box of them for the fun of it.
Are they worth it for a quick energy boost or not?

Hello Adam,
Let me start by saying that I have no medical training, and little understanding of Diabetes.
About 20 years ago I saw a TV documentary about investigations into the deaths of people who had got into difficulties during extreme weather conditions here in the UK. What seemed to have prompted this investigation was the fact that so many of the unfortunate individuals had been found so close to locations that would have most likely ensured their survival (Very short distances from an occupied building remote farmhouses etc).
From what I can remember, it was thought that many of the individuals had eaten foodstuffs that contained a high concentration of refined sugar (Dextrose being one of many types of refined sugar).
As I understand it, when high concentrations of refined sugar enter the bloodstream the body compensates by pumping a huge amount of insulin into the bloodstream to reduce the sugar levels to a more nominal level. I have heard many people report that after an initial boost in energy from the refined sugar, there follows a dramatic feeling of fatigue.
The documentary concluded that it was this fatigue that had significantly contributed to the deaths of those concerned. It also asserted that if one is going to eat a foodstuff high in refined sugar, to give you an energy boost in a critical, survival situation, one should refrain from doing this until you are a few hundred metres from the place of safety.
It has to be said that all the individuals studied in the documentary were in a very weakened state due to exhaustion and hypothermia (Crawling on their hands and knees in deep snow, type situations), and this in combination with the fatigue caused by the reaction to the refined sugar, was what was thought to have resulted in their demise.
If I remember correctly, it was suggested that had they delayed the eating the high sugar energy bar until they were around a 100 metres from the building they were making their way toward, they would probably have survived.
However, I should restate that I have no medical expertise, and due to the length of time that I viewed the documentary, my memory of the programme may not be what it could be.
Best regards,
Paul.
