Sugar & Inflammation
topic
Excess dietary sugar — particularly fructose and refined sucrose — promotes inflammation through multiple direct mechanisms: fructose metabolism producing uric acid (activating NLRP3 inflammasome), advanced glycation end-product (AGE) formation from glucose reacting with proteins, activation of NF-κB inflammatory transcription factor, and promotion of gut dysbiosis that increases gut permeability and endotoxin translocation. Added sugar consumption above approximately 50g/day is associated with measurably elevated CRP, IL-6, and TNF-alpha in clinical studies.
Role
The direct inflammatory effects of sugar provide the mechanistic explanation for epidemiological associations between sugar consumption and diseases as diverse as gout, cardiovascular disease, Alzheimer's, and certain cancers — unified by their shared inflammation-dependent pathophysiology. Most people understand that sugar 'is not good for you' without knowing that it is specifically and mechanistically pro-inflammatory in ways that directly promote the pathophysiology of these conditions — a mechanistic understanding that converts vague dietary aversion into specific, motivated modification.
