Cardiovascular disease (CVD) remains a leading cause of death in patients with chronic kidney disease (CKD). CVD is now thought to result from the interplay of several factors including inflammation, oxidative stress and endothelial dysfunction. Advanced glycation end products (AGE) are known to be elevated in patients with CKD and these compounds possess these pro-oxidant, pro-inflammatory and anti-endothelial properties. There has been a great deal of literature linking diet and inflammation, and recent work has shown the diet to be a significant contributor to the body's AGE pool. We herein hypothesize that a diet high in AGE plays an important role in the initiation of chronic subclinical inflammation that seems to underlie the high prevalence of CVD in CKD patients. Herein we will briefly examine the evidence linking different components of diet with inflammation in CKD patients. We will then focus on the role of dietary AGEs in inflammation and potentially CVD in CKD, and in conclusion, we will propose dietary modifications as part of a multifactorial approach to ameliorate unhealthy lifestyles among CKD patients. The most important message is that simple changes in culinary technique rather than in the food nutrient composition may be the most important part of preventing CVD in this population.
