  • Summer is coming to an end, so it’s time to stop enjoying all those barbecues, and

  • start worrying about cancer!

  • Hello extra crispy colonels, Trace here for DNews.

  • We all hate it when our food gets burnt.

  • I know I’ve flipped over more than one table at a fancy restaurant because my Brussels

  • sprouts weren't just overcooked -- but BURNT.

  • BURNT, Jessie.

  • I'm still bitter about it.

  • But as it turns out, my seemingly excessive displays of disgust are more reasonable than

  • it might seem.

  • Besides tasting and smelling absolutely awful, research has shown that burnt and overcooked

  • food might actually cause cancer.

  • Your Mom was right.

  • Sort of.

  • Although studies on dietary consumption of burnt food won't directly sayyou will

  • get cancer if you eat that blackened wing”, the risk is still there.

  • See, in 2002 scientists at Stockholm University found that starchy foods, like French fries

  • or garlic bread, developed acrylamide after being heated to 120 degrees Celsius.

  • The chemical is produced by a reaction between asparagine, a non-essential amino acid, and

  • certain sugars like fructose.

  • This chemical was not found in unheated foods, or those that had been boiled and unable to

  • reach the necessary temperature.

  • So, it’s not only burnt foods, but pretty much all starchy foods exposed to high enough

  • heat, including well-done, fried, and baked.

  • Now, you might be inclined to think that getting cancer from burning food to a crisp would

  • work in the same way as getting cancer from smoking.

  • And youre sort of right.

  • That’s because the cancer risk stems from the chemical acrylamide, and acrylamide is

  • also found in cigarette smoke.

  • So, pat yourselves on the back for being on the money.

  • In studies where acrylamide was given to lab rats in their drinking water, it caused tumors

  • in the lungs, thyroid, adrenal glands, and testicles.

  • [eesh] It also seemingly caused mutations in mouse sperm DNA that can then be passed

  • onto their offspring.

  • So not only does it give animals cancer, but it also hurts their babies.

  • In humans, the acrylamide irritates skin and is believed to be a tumor initiator, but the

  • link to cancer isn't as hard and fast.

  • In studies where it actually caused cancer in rats and mice, those animals were being

  • fed doses roughly 1,000 to 10,000 times higher than what could possibly be found in a burnt

  • batch of French fries or a crispy burger.

  • Nonetheless, acrylamide is classified as a Group 2A carcinogen by the International Agency

  • for Research on Cancer, meaning it probably causes cancer in humans, but not conclusively.

  • In 2010, Harvard researchers found an increased risk of ovarian and endometrial cancer in

  • women who didn't smoke, but did eat foods with lots of acrylamide.

  • And, a meta-analysis from 2015 found that dietary acrylamide might be related to kidney

  • cancer.

  • Still, and again, there is no conclusive evidence that acrylamide is responsible for any of

  • the most common cancers, like breast cancer.

  • So, since there’s no direct proof, you can just limit your intake of well-cooked foods

  • and youll be fine right?

  • Wrong.

  • See, cooked and burnt foods can still give you cancer even if you don’t eat them!

  • BECAUSE OF SECOND-HAND SMOKE.

  • Not really.

  • But kinda!

  • When you cook food over an open flame, especially muscle meats like beef, pork, fish, or poultry,

  • the drippy-byproducts fall into the fire, producing two types of chemicals: polycyclic

  • aromatic hydrocarbons -- PAHs -- and heterocyclic amines.

  • As you cook, those two chemical groups both become airborne, or volatile, and are also

  • consideredmutagenic”, which is not a word you want associated with standing near

  • an open barbeque pit.

  • A mutagen is something that causes changes in your DNA, and it can lead to an increased

  • risk of cancer.

  • PAHs have been correlated with skin, lung, bladder, liver, and stomach cancer in animal

  • testing.

  • And prostate, colorectal, and pancreatic cancers have been associated with eating burnt, or

  • nearly burnt meats, which The National Cancer Institute ties to these chemical groups.

  • Now look, this all sounds pretty scary.

  • But remember, the studies are just pointing out these chemicals exist in the world, and

  • cause cancers sometimes.

  • They're relatively inconclusive.

  • Although there is some correlation between eating well-cooked meat, or starchy foods

  • cooked at high temperatures and certain types of cancers, it is nowhere near as clear as

  • the link between, say, cigarettes and lung cancer, or sun exposure and skin cancer.

  • You can be guaranteed research is still ongoing in this area.

  • Just moderate your intake of these risky foods, and you should be okay.

  • Plus, less mammal meat is better for you and the environment anyway -- just don't grill

  • your veggies...

  • Cancer-free quinoa, here I come!

  • It's not just grilled foods and starches, there is another indication that everyone's

  • favorite belly meat -- BACON.

  • YES BACON -- might be killing you.

  • In fact, processed meats in general were named cancer-causersbut what IS a processed

  • meat?

  • I looked into it last year, and it was fascinating!

  • Check it out.

  • What do you think is the best way to cook meat?
