Over-cooked meat

Hi all, what are you stance on over-cooked meat ? Do you think it is a big threat or only a minor problem easily counterbalanced by ketogenic diet ? Are you very careful to not over-cook the meat ?

The Dangers of Grilled Meat

Kentucky Fried Chicken (KFC) is being sued by a doctors group for allegedly selling grilled chicken containing dangerous levels of PhIP, a cancer-causing chemical.

The Physicians Committee for Responsible Medicine said tests conducted in an independent laboratory revealed that PhIp was present in all 12 grilled chicken samples bought from six East Bay KFC restaurants in May.

PhIP is a compound formed when meat is charred at high temperatures, and was found to cause prostate cancer and breast cancer in animals, healthy living advocate Dr. Joseph Mercola explains.

The doctors group accused KFC of not warning customers that they are being exposed to PhIP when they order grilled chicken.

The group made the same arguments last year in a case filed against other restaurants that sell grilled chicken, including Burger King and McDonalds. The former agreed to warn customers of the presence of PhIP, but the latter and the other defendants held their ground until the case was dismissed.

But whether or not this new case against KFC is dismissed, if you’re thinking that grilling is a healthier way of cooking food, think again.

Besides PhIP, other chemicals commonly produced when you barbecue food include heterocyclic amines (HCAs), polycyclic aromatic hydrocarbons (PAHs) and advanced glycation end products (AGEs).

HCAs, PAHs and AGEs have been linked to cancer, oxidative stress, inflammation and an increased risk of heart disease, diabetes and kidney problems.

So does this mean that you should stop inviting your friends over to your barbecues?

For Dr. Mercola, eating most of your meals uncooked can have a profound impact to your health because the important components of food, such as biophotons, enzymes, oxygen, hormones and phytonutrients, are still intact.

Since it’s not always possible to do this, the next best thing is to avoid overcooking your food because aside from producing dangerous chemicals, overcooking gives added burden to your body to digest and assimilate what you eat because the higher the temperature you use for cooking, the longer the food stays in your gut.

If you’re eating healthy most of the time, your body will typically have enough reserves to compensate for the potential damage caused by eating grilled food.

Here are Mercola’s tips to help you reduce the amount of dangerous substances produced while grilling:

• Choose only high-quality, organic and grass-fed meats, like grass-fed beef and free-range organic chicken
• Marinate the meat before cooking. You can use red wine or beer for steak, and olive oil, lemon juice and garlic for chicken to help lower HCA levels.
• Cook the meat partially before grilling or cook smaller portions to shorten the cooking time and give HCAs lesser time to form.
• Use a rack or a cedar plank for indirect heat rather than grilling the meat directly on the coals.
• Trim the fat off the meat before grilling to help lower the amount of PAHs.
• Keep the coating thin to avoid charring the meat.
• Cook the meat as little as possible. At most, the meat should be rare or medium-rare. Sear the meat quickly on both sides to leave the inside mostly raw.

I wouldn't call anything that you'd ever get at KFC as "meat". But I think overcooked meat is very rough, and tastes terrible. Undercooked or raw meat may have parasites as well as being more difficult to digest and thereby not giving you the same amount of energy as cooked meat. Also, purely subjective, but it's not exactly palatable either! :)

See this study for example: http://www.ncbi.nlm.nih.gov/pubmed/19732938

I tend to fry my steaks to medium or medium-well, and my chicken/pork is fully cooked (no pink). But I take it off the pan as soon as it's done because frying any longer just makes any meat firmer and less juicy/palatable. All at low heat. I haven't really looked at the health issue side of overcooked meat, but I'm still careful not to overcook it as a personal preference, so I wasn't really worried about it either. I also tend to fry everything in a lot of bacon grease, which is easier to control than grilling where you have small metal surfaces directly in contact with the meat, osit.

Boiling works differently though. I've made bone broth for 8+ hours before and included some meat with the bones. It makes it super tender and delicious! I'm not sure if the lengthy cooking period leeches all the nutrients out of the meat, but it doesn't matter because I'm drinking the broth in the process, so the meat is just there for fun.

Cooking our meat seems have enabled us to evolve such big energy-hungry brains (in addition to eating mostly meat/fat in the first place, which shrunk our gut allowing the brain to grow). So I honestly haven't seen any convincing reason to ever eat raw meat, or to overcook it for that matter!
 
I agree with SAO - that's exactly what I do. I know Mercola is a bit of a raw-er, but you have to physically destroy plant matter before being able to digest it - be it heat or blending. Someone mentioned earlier in this thread that some studies (i think it was carrots) released more nutrients when cooked (can't find it),

Another thing is that grilling meat over an open fire would probably have been the earliest way of preparing meat for our ancestors, so I believe that we are adapted to this.

So until there is clear new evidence that grilling is really harmful I'll continue what I do.
 
Yeah, the evidence shows that humans evolved with the big brains and small guts -- the "expensive tissue" hypothesis -- by eating lots of meat and mostly animal fats cooked on an open fire. So, I can't see any major problem with barbequing your grass-fed meat. But I do like mine medium-rare.

Also, Mercola advises to marinate the meat in beer. Bad idea all around, not least for the gluten.

On an open fire or on coals ?

You can also cook, by example, the head of an animal under the ground.

I once cooked some meat in a fireplace, and it rapidly became burnt and black at the surface.
 
The advice to marinade in beer seems to be based on the antioxidants in the beer. But beer is not the only thing that contains antioxidants, duh.

What about marinading in black tea for instance? Rosemary and oregano also contain antioxidants that help to preserve fats during cooking, though I don't know if there is enough to make much of a difference.

So what foods contain more antioxidants than black beer? Here is an enormous list of antioxidant content of foods, and yes, black tea has more antioxidants than beer it seems:

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2841576/bin/1475-2891-9-3-S1.PDF

So this makes me wonder, has anyone tried making a green tea (black, oolong, white, etc) marinade, or perhaps adding it to the crock pot or pressure cooker when making a roast? What other things might make a healthy marinade?

That's actually a very interesting idea. I always thought of marinating in beer was for the taste, but i think i will try experimenting with tea marinades.

I was thinking of this the other day, but for a different reason. I wonder how good, bad, or indifferent or you charcoal is? As in burnt meat.
