The Unexpected Dangers of the Barbecue

Well folks, it’s summer in the Maritimes at last, and we all know what that means: Mosquitoes. Oh, and barbecuing, that most festive of occasions when we move our cooking and dining into the great outdoors and try to squeeze every last drop of summer sun out of our oh-so-brief summer. There’s nothing more relaxing than lounging around the grill on a sultry summer night, nursing a cold drink and gossiping with friends. Perfectly delicious, and perfectly harmless, right?

WRONG. Unfortunately, evidence shows that barbecuing meat on the grill causes a dangerous, cancer-causing substance called PHiP to form in the meat. PHiP, also known as 2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine in scientific circles, is a dangerous substance that is formed when meats are cooked at very high temperatures, such as when you barbecue. A study published in the American Association for Cancer Research in 2007 found that the more grilled red meat that a man consumed, the more PHiP was found in prostate tumour cells. Grilled hamburger had the greatest link with prostate cancer of all the different kinds of meat, and that’s bad news. (Studies at the UC Davis Cancer Centre in California showed similar risks, although they found that chicken had the greatest potential to form PHiP during cooking.)
In 2001, researchers from the University of Guelph found that it can increase the incidence of breast cancer as well as increase the cancer risk of nursing infants whose mothers eat a lot of grilled meat.

PHiP is caused by cooking muscle fibres at very high heat. The higher the cooking temperature, the more PhiP that forms in the meat. This applies not only to food cooked on the BBQ, but also to so-called “healthy” grilled chicken served in restaurants. A study performed by the Physician’s Committee for Responsible Medicine in 2008 tested one hundred samples of grilled chicken from seven different chain restaurants, (including Burger King and McDonald’s) and PHiP was found in every single one.

So what’s a Maritimer to do? Well, there are few things you can do to minimize the risk. Marinating the meat before cooking, turning frequently, and choosing lean cuts of meat does help. However, other cooking methods such as baking and roasting cause far fewer PHiP’s to form. Better yet, give some non-meat foods the old college try this summer. Veggie burgers, Portobello mushrooms, and vegetable shish kebabs are all delicious on the grill without delivering a dose of carcinogen along with the entrĂ©e.

Welcome!

These days, it's harder than ever before in history to choose a healthy diet for yourself and your family. We live in a world that is grossly unbalanced in the sense that millions of people go hungry while millions of others are suffering the affects of obesity and other diseases related to too much food.
***
Here in North America, most of us have no problem getting enough calories. Food for the most part is cheap and plentiful. Instead, we face a dazzling array of products to choose from every time we step into a store. In fact, the average grocery store can have more than 30, 000 items to choose from! Fast food restaurants are popping up on every street corner, and more and more of our meals are being eaten outside the home. Food labels are written in confusing language (sometimes, I suspect, deliberately so) and few people are equipped with the knowledge to decipher them.
***
To further muddy the waters, the manufacturers of these products are pouring millions of dollars into advertising to cleverly convince you that you need to buy them, and still more millions into developing more and more processed, nutrient-poor products every year. It seems that consumers are being successfully convinced to spend their hard-earned money on attractive, colorful "non-food" instead of wholesome, basic foods. The best of intentions are helpless against the juggernaut of big business.
***
So, what do we do? Well, we need to become well informed about just exactly what we are eating. Most of the average consumer's information about food is coming from the very companies trying to sell it to you, and often this information is self-serving and should not be trusted. We need to get the straight truth from a disinterested third party, who has nothing to lose or gain from your choices at the supermarket. I want to help! I will be turning a critical eye to a variety of products, health claims and scientific breakthroughs, and helping you to understand what they mean to you, the health conscious consumer.

The field of nutrition is complicated, and is likely to remain so for quite some time yet. It's made even more complicated when the manufacturer of every product wants to convince you that you need to buy their product in order to be healthy. But even so, it IS possible to truly make healthy, empowering choices at the market. Stop by often and I'll try to set the record straight.
