It seems neither. A new study claims that grilled, fried, or broiled meat contain toxins called "advanced glycation end products" (AGEs). And, Robert Preidt of HealthDay News
reports that AGEs can lead to a myriad of serious health problems, like diabetes and vascular disease
. Here’s more:
Grilled, fried or broiled animal products such as meats and cheeses contain a class of toxins called "advanced glycation end products" (AGEs), which have been linked to inflammation, insulin resistance, diabetes, vascular and kidney disease, and Alzheimer's disease, say a team from the Mount Sinai School of Medicine in New York City…
…"AGEs are quite deceptive, since they also give our food desirable tastes and smells," senior author Dr. Helen Vlassara, professor of medicine and geriatrics, and director of the Division of Experimental Diabetes and Aging at Mount Sinai, said in a prepared statement.
"So, consuming high amounts of grilled, broiled or fried food means consuming significant amounts of AGEs, and AGEs in excess are toxic. People should be given information about AGE intake and be advised to consider their intake in the same way they would think about their trans fats and salt intake. They should be warned about their AGE levels the way they are about their cholesterol levels or cigarette smoking," Vlassara said.
Dr. Fuhrman makes it pretty clear. Too much meat and other animal products can contribute to serious health problems, namely cancer and cardiovascular disease. Here are couple posts that highlight this connection:
Okay, back to cooking foods. Does it really matter how we prepare our food? Be it animal or vegetable-based. Well for starters, Dr. Fuhrman doesn’t thinking frying is a good idea. He explains why in Disease-Proof Your Child
Water-based cooking is the preferred way to cook because you can avoid cancer-causing acrylamides that are created when foods are browned by baking or frying.
Never eat browned or overly cooked food. Burnt food forms harmful compounds. If by accident something is overcooked and browned, discard. Avoid fried food and food sautéed in oil. Experiment with low heat cooking to prevent nutritional damage to the food and the formation of dangerous heat-generated compounds.
Now, recently I asked Dr. Fuhrman if acrylamides show up in other foods, like cooked meats, specifically barbecued meat. No surprise here, his answer was yes. Actually, he pointed out that acrylamides form in all foods. Check out this study from the Scandinavian Journal of Nutrition
, it sheds some light on the development of acrylamides
The exact chemical mechanism(s) for acrylamide formation in heated foods is unknown. Several plausible mechanistic routes may be suggested, involving reactions of carbohydrates, proteins/amino acids, lipids and probably also other food components as precursors. With the data and knowledge available today it is not possible to point out any specific routes, or to exclude any possibilities. It is likely that a multitude of reaction mechanisms is involved. Acrolein is one strong precursor candidate, the origin of which could be lipids, carbohydrates or proteins/amino acids. Acrylamide is a reactive molecule and it can readily react with various other components in the food. The actual acrylamide level in a specific food product, therefore, probably reflects the balance between ease of formation and potential for further reactions in that food matrix. There are indications in support of that the Maillard reaction being an important reaction route for acrylamide formation, but lipid degradation pathways to the formation of acrolein should also be considered.
At this point it kind of seems like a basic math equation. If too many animal products are bad and eating overly cooked food is also bad, then putting the two of them together has got to be really bad, right? Well, it sure seems that way. In Disease-Proof Your Child
Dr. Fuhrman considers barbequed meat (and cheese) one of the worst foods you can eat for health and longevity. From the book:
Worst Seven Foods for Health and Longevity
- Potato Chips and French Fries
- Sausage, hot dogs
- Pickled, smoked or barbequed meat
Foods high in saturated fat and trans fat are consistently associated with high cancer rates. Cheese and butter typically contain over ten times as much saturated fat as fish and white meat chicken and turkey.
Add the carcinogenic potential from heated and overcooked oils (usually trans containing) delivered in doughnuts and fries with the powerful cancer inducing properties of carbohydrates cooked at high heat (acrylamide formation) and you have a great cancer potion.
So, will people heed these warnings and cut back on the amount of animal products they eat and be careful not to dangerously cook their food? My guess, probably not, especially with this kind of rhetoric kicking around the blogosphere. Like LivinLaVidaLowCarb’s ringing endorsement of frying meat in butter
—sadly, I’m not kidding. Proceed with caution:
I agree with the advice to shun the fried foods specifically because of the breading. But if you want to fry up your meat in a pan full of butter, then knock yourself out. It’s a healthy way to enjoy that succulent protein-loaded food.
While it’s nice to bake, broil, and especially grill meats, don’t fall for the illusion that cooking these ways is any healthier than cooking meat in fat. Avoid the trans fats, of course, but you shouldn’t worry about saturated fats as long as you are livin’ la vida low-carb.
Take a moment to note that butter is also on Dr. Fuhrman’s list of the seven worst foods. Okay, it gets worse. Check out this quote from Carbohydrate Addict, apparently this Atkins dieter thinks grilled-cheese is fabulous
—sigh. Here it is:
I think one of the reasons Atkins was so perfect for me was because I was on low fat/low cholesterol for sooooo many years. All of the forbidden foods suddenly became okay to eat without guilt and my cholesterol is finally FABULOUS. I'm still on a high when I eat them! Egg salad, bacon, chicken wings, mac and cheese, grilled cheese.... YUM!
Yum? For bacon and egg salad? Whoa! What a world we live in. Reading rants like this makes me think about the opposite. What does eating a lot of fruits and vegetables do for us? Well, when you’re talking health and disease-prevention, Dr. Fuhrman explains they’re the best! From Fruits and Veggies vs. Diabetes and Colon Cancer
While fruits and vegetables are excellent sources of nutrients, the consumption of vegetables is more helpful in reducing cancer because they contain much higher amounts of cancer-protective compounds-- especially green vegetables. Among these green vegetables, the cruciferous family has demonstrated the most dramatic protection against cancer. Cruciferous vegetables (broccoli, brussels sprouts, cauliflower, kale, bok choy, collards, arugala, watercress, and cabbage) contain a symphony of phytonutrients with potent anti-cancer effects. Isothiocyanates (ITCs), which are perhaps the best studied, have been shown to provide protection against environmental carcinogen exposure by inducing detoxification pathways, thereby neutralizing potential carcinogens.
These vegetables also contain indole-3- carbinol (I3C). Indole-3-carbinol has been shown to reduce the risk of breast cancer by decreasing estrogen activity. Important recent studies have shown that cruciferous vegetables and the compounds they contain can do the following:
- Halt the growth of breast cancer cells1
- Dramatically reduce the risk of colon cancer2
- Prevent the replication of prostate cancer cells and induce death of cancerous cells3
- Inhibit the progression of lung cancer4
And here’s more, from Is Heart Disease Totally Preventable
? Take a look:
The Eat to Live vegetable, fruit, nut, and bean-based diet has been shown to be the most effective cholesterol-lowering dietary approach in medical history. This newsworthy data with the potential to save millions of lives has been ignored by the mass media. With this dietary approach, most patients drop their total cholesterol below 150 and LDL below 100, without the need for medications.
During the two years that the Eat to Live vegetable, fruit, nut, and bean-based diet has been under research study by the University of Southern California, patients have shown an average weight loss of forty-nine pounds, the most sustained weight loss ever recorded in a medical study in history.
In areas of the world where people eat a diet of unrefined plant foods, people have total cholesterol levels below 150, and there is zero incidence of heart disease in the population.5
