Is glucose low histamine-compatible?

What to know about glucose

Glucose, which appears on most ingredient lists as dextrose, is the rare sweetener that grades A on every trigger column we track: total FODMAPs, fructans, GOS, excess fructose, polyols, lactose, gluten, histamine content, histamine liberation, salicylates, oxalates, nickel, sulfites, nitrites, glutamates, tyramine, caffeine, dairy protein and SIBO fermentability. That is structural, not luck. Table sugar is sucrose, half glucose and half fructose. Honey, agave and high fructose corn syrup carry fructose in excess of glucose, and that excess is the precise condition that saturates GLUT5 transport in the small intestine and produces the bloating, wind and loose stools of fructose malabsorption. Glucose has no fructose half to malabsorb. It is taken up actively and almost completely in the small intestine, so it does not reach the colon to ferment, which is why its SIBO grade is A rather than the E that most liquid sweeteners carry. It goes further than merely neutral: glucose eaten alongside fructose actively improves fructose uptake, which is why the FODMAP rule is written as "fructose in excess of glucose" and why balanced-sugar fruit is tolerated when honey is not. The honest caveat is metabolic rather than digestive. Glucose is refined sugar with the fastest blood-sugar response of the common sweeteners, graded D for anti-inflammatory eating and D against DASH and Mediterranean patterns.
