AGEs: Advanced Glycation End-products

AGEs (Advanced Glycation End-products) are compounds formed by the spontaneous, non-enzymatic binding of reducing sugars to proteins, lipids, and DNA. They are major markers of biological aging and diabetic complications. The more sugar you consume, the more you age at a molecular level.

Mechanism of Formation

1. Glucose or fructose + amine group (Lys, Arg) → Schiff base
2. Amadori rearrangement (hours to days)
3. Oxidation and dehydration → mature AGEs (days to years)
4. Cross-linking of proteins, tissue deposits

Pathological Consequences

• Stiffening of collagens (skin, blood vessels, joints)
• Accelerated atherosclerosis
• Diabetic nephropathy
• Diabetic retinopathy
• Cataracts (glycated crystalline)
• Alzheimer's disease (glycated Aβ)
• Sarcopenia (glycated muscle collagen)

The Role of Dietary Sugar

The more sugar you consume (especially fructose, which is ~10× more glycating than glucose), the more AGEs you produce. A concentrated drink with 35g of sugar/100ml (GIMBER) significantly accelerates AGE formation — paradoxically contrary to a "health" objective.

Natural AGE Inhibitors

• Curcumin: inhibits AGE formation and RAGE (receptor) activation
• [6]-gingerol: documented AGE inhibition in animal models
• Piperine: enhances curcumin
• Carnosine, thiamine, resveratrol

Anti-AGE Strategy

1. Reduce added sugars (≤25g/day WHO)
2. Prioritize gentle cooking methods (steaming, boiling) vs grilling/barbecuing
3. Dietary antioxidants (activated Nrf2)
4. Regular physical activity (↑ AGE clearance)

AGEs and INTI

INTI with 1.19g of sugar/100ml minimizes AGE formation — unlike GIMBER (35g) which actively contributes to their formation. The curcumin + piperine in INTI further inhibits AGE formation downstream.
