As a Registered Dietitian Nutritionist, I am frequently asked if eating meat is bad for you. My answer is always “it depends.” Many of us are now aware of the importance of buying animal products that are raised humanely and without antibiotics and hormones. This includes hormone/antibiotic free, organic, pasture raised, free range, and organic pasture raised products. Additionally, meat from pasture raised animals contain a healthier balance of omega-6 to omega-3 fatty acids than grain-fed equivalents. Though no matter how they are labeled, pork, beef, and chicken are great sources of highly bio-available protein as well as zinc, iron, and several of the B vitamins.
Great! So, you bring home a nice sirloin steak and you throw it on the grill. You hear it sizzling, see the meat turning a pleasing brown color, and smell that delicious seared meat aroma. This is where that healthy (and expensive) piece of organic pasture raised meat turns bad.
Grilled meats and meats prepared by other high-temperature dry cooking methods such as roasting and pan frying create toxic compounds called Advanced Glycation End Products (AGEs). AGEs are basically cellular debris that can build up in your body and cause oxidative damage to tissues and organs. They have been implicated in many chronic diseases such as diabetes and Alzheimer’s disease.
How then, do you prepare a healthy meat-containing meal? For lower AGE content, use low-heat moist cooking methods such as poaching, stewing and sautéing. However, if you are really craving that grilled piece of meat, marinade it in either a citrus or vinegar containing solution for at least 2 hours prior to cooking. The acid inhibits AGE formation during the cooking process.
The table below shows a comparison between different cooking methods for meats and the resulting AGE content. Note that any food cooked, at high temperatures, such as potatoes, can also create substantial amounts of AGEs. Also be aware that even though raw meat has the lowest AGEs, you should always consume it cooked. Make sure to follow the guidelines for safe cooking temperatures.
