Title: "The Glycation Cascade: How Blood Sugar Fuels Inflammation and Chronic Disease."

Friday, September 11, at 8:30 AM on the Main Stage

Summary:

Chronic, low-grade inflammation is now recognized as a shared pathological feature underlying many of the most prevalent chronic diseases, including type 2 diabetes, cardiovascular disease, obesity, non-alcoholic fatty liver disease, neurodegeneration, and cancer. This presentation examines a central biochemical driver of that inflammation: the glycation of proteins by glucose and the subsequent accumulation of advanced glycation end-products (AGEs). The presentation establishes the physiological sequence linking glycemia to disease. Sustained elevations in blood glucose increase the rate of non-enzymatic glycation, generating AGEs that impair protein function, alter immune signaling, promote oxidative stress, and contribute to insulin resistance. Familiar clinical markers such as hemoglobin A1c are used to ground these mechanisms in measurements clinicians already employ, reinforcing the continuity between metabolic status and systemic outcomes. Particular attention is given to the relevance of these processes for oral-systemic health. The same glycation and inflammatory pathways that affect distant organ systems also influence the periodontal and oral environment, positioning dental and allied health professionals to recognize and address metabolic risk as part of comprehensive patient care. The presentation then reviews evidence-based strategies that may attenuate AGE formation and systemic inflammation, including carbohydrate moderation, intermittent fasting, and the substitution of fermentable sugars with alternative sweeteners such as xylitol. Current human and animal research, including recent findings, will be presented to illustrate both the promise and the limitations of these approaches. Upon completion, participants will be better equipped to explain the glycemia–glycation–inflammation relationship, interpret its clinical significance, and discuss strategies that support metabolic and oral-systemic health.

1. Describe the physiological sequence linking elevated glycemia to non-enzymatic glycation and the formation of advanced glycation end-products (AGEs).
2. Explain how AGE accumulation contributes to chronic systemic inflammation, impaired immune and metabolic function, and the pathogenesis of major chronic diseases.
3. Identify the relevance of glycation and inflammatory pathways to oral-systemic health and the role of dental and allied health professionals in recognizing metabolic risk.
4. Evaluate strategies, including carbohydrate moderation, intermittent fasting, and alternative sweeteners, for their potential to reduce AGE formation and systemic inflammation.

1. Use HbA1c as a glycation conversation-starter, not just a diabetes screen.
2. Counsel patients on meal frequency and carbohydrate load, not just carbohydrate type.
3. Position alternative sweeteners such as xylitol within a broader anti-inflammatory strategy.
