Yes, that is true of the effect of fructose in that it helps the overall absorption of sugars that are a combination of glucose and fructose.Sorry, forgot to comment the above quote: The metabolism of isolated refined starch (glucose) vs. sucrose (glucose+fructose) or a glucose/fructose mix is not at all the same. See, for example:
J Clin Endocrinol Metab 2000 Dec;85(12):4515-9. Acute fructose administration decreases the glycemic response to an oral glucose tolerance test in normal adults. Moore MC, Cherrington AD, Mann SL, Davis SN. “In animal models, a small (catalytic) dose of fructose administered with glucose decreases the glycemic response to the glucose load.” “In conclusion, low dose fructose improves the glycemic response to an oral glucose load in normal adults without significantly enhancing the insulin or triglyceride response. Fructose appears most effective in those normal individuals who have the poorest glucose tolerance.”
This is why I mentioned above that if one must eat plain bread or white rice without (or not enough) fat, it would be wise to eat some fruit with it...
I used to find that I get hungry quickly when I eat a piece of white bread by itself compared to eating a teaspoon of white sugar on an empty stomach. This was already when I have fixed my blood sugar issues to a large extent. But maybe I wasn't totally fixed, as I felt that I should be able to eat the white bread without quickly feeling hungry were I totally fixed.
