Quality Criteria for Studies on Dietary Glycation Compounds and Human Health.

Current reports increasingly associate dietary "advanced glycation end products" ("AGEs") resulting from the Maillard reaction (glycation) between reducing sugars and amino compounds in foods with pathophysiological consequences, such as chronic inflammation, atherosclerosis, and metabolic syndrome. Heated foods are therefore suggested to pose a potential risk for human health. However, studies in this field are very often based on questionable quantitative data and inadequate structural characterization. To improve the situation, the present perspective suggests quality criteria for future studies and the assessment of the currently available literature.
