** CAUTION *** I do not know how any of this affects people with diabetes. I am basing every thing on research about sugars and my porphyria needs.
We need glucose during an attack and to hold off an attack. Well, that is a little simplistic, in that we all need glucose; but, most people without porphyria derive enough glucose from their diets, where we cannot. Anyway, here is the result of my research into sugars:
Monosaccharides are simple, basic sugars: glucose, fructose, galactose
Disaccharides are a combination of monosaccharides: sucrose (table sugar) = glucose + fructose, lactose (milk sugar) = galactose + glucose, maltose = glucose + glucose.
Glucose (AKA dextrose) – this is the type sugar that powers our bodies; carbs and starches are broken down in our bodies to produce glucose. When you eat glucose tablets, the glucose goes directly into your bloodstream.
Fructose – sometimes called fruit sugar. Fructose is processed in your liver. High levels of fructose act as a signal to the liver to store glycogen. For people with porphyria, fructose should be avoided. The problem with this is that most processed foods have high fructose corn syrup as an ingredient.
Honey contains both glucose & fructose as monosaccharides. The crystals that form in honey as you cool it is glucose.
Where I get glucose:
Powdered glucose (dextrose). I get this in large bags. Here is the cheapest source that I’ve found.
For tablets, I would prefer to get them at Publix, but, Target is cheaper. Publix $5.99 for a 50 count jar; Target is $3.99 for the same thing. No brainer. I also carry around little tubes that hold 10 tablets; they are easier to fit in my pocket.
