In healthy overweight adults, consumption of a single meal high in dietary advanced glycation end products does not significantly alter postprandial insulin, triacylglycerol, or inflammatory cytokine levels, with effects limited to glucose and oxidative stress markers.

When a person eats a meal with lots of advanced glycation end products, these compounds get absorbed into the blood and cause cells to produce more reactive molecules that damage fats and proteins. This damage raises blood sugar because it interferes with how cells take up glucose, but it does not change how much insulin the pancreas releases, how much fat moves in the blood, or how the immune system responds. The body only reacts to the sugar spike and the cellular damage, not to other metabolic or immune signals.
