AGEs also exist in foods. Animal-derived high-fat protein sources are a major source of harmful dietary AGEs and can induce inflammation and oxidative stress similarly to an excess of dietary sugar. Beef surpasses other forms of protein, having the highest amount of dietary AGEs. Moreover, if grilling or frying is your go-to cooking method, this will result in additional AGE formation, too. No need to avoid the BBQ cookouts all together, since there are ways to lower your AGE exposure, like marinating meat in acidic solutions (e.g. lemon, vinegar) prior to grilling, for example. If lowering your overall intake of meat isn't your game plan, simply changing the way food is cooked can also help. Using moist food prep methods like poaching or steaming, as well as briefer cooking times, will dramatically reduce the number of AGEs formed during the cooking process.
