Protein and the Story of the AGEs Advanced glycation end-products (AGEs) can do some serious damage, especially over time. An article in The Clinical Journal of the American Society of Nephrology makes several important points about protein and its relationship to many of the diseases of aging: • Human studies indicate that excess dietary protein promotes progressive kidney damage by increasing the AGE burden. • A prudent approach is to recommend that people with chronic kidney disease achieve the recommended dietary allowance of protein—0.8 g/kg per day, or about 10 percent of total caloric intake— with an emphasis on high-quality protein, low in AGEs. • Conversely, very low dietary protein intake may lead to malnutrition, especially in those with advanced chronic kidney disease. • The dietary AGE load can be minimized by consuming nonmeat proteins. • There are several culinary methods that reduce AGE formation during cooking—steaming, poaching, boiling, and stewing. Frying, broiling, or grilling should be avoided, as they promote AGE formation. • Limitation of dietary AGEs seems prudent in those with obesity, diabetes, and other risk factors for chronic kidney disease.i With the gradual onset of kidney failure, acidosis again ensues and will lead to all types of inflammation and metabolic abnormalities. The preceding recommendations for how to avoid turning a meal into AGEs should become a major agingmanagement technology for Baby Boomers everywhere. — Leonard Smith, M.D.
