Easy Ways to Avoid (Cancer Causing) Acrylamide in Home Cookinghealthy fatsby Sarah TheHealthyHomeEconomist

The realization thatplenty oftraditional fats in the diet is not dangerous andis,in fact, incredibly necessary for vibrant healthcan sometimes lead to the conclusion that fried foods are fine to eat on a regular basis.Unfortunately, this isnt the case.Frying and even baking and broiling carbohydrates creates a carcinogenic chemical called acrylamide in the food. This is the case even if healthy, high heat fats like tallow, lard, ghee or coconut oil are used.The good news is that when traditional cooking methods are followed, the dangerous creation of acrylamide in your food can be avoided!What Exactly is Acrylamide?Acrylamide is a chemical compound that iswhite, odorless andsoluble in water. It is used in numerous factory processes suchas making paper, dyes, and plastics. It is used to treat both drinking water and wastewater. Acrylamide is also found in cigarette smoke.In 2002, Swedish researchers discovered high levels of acrylamides in starchy foods as this chemicalis formed when carbohydrates are cooked at temperatures above 250 F/121 C. The foods highest in acrylamide after cooking or roasting include potatoes, grains, and coffee (1). Whats most important to realize is that the longer and higher you cook starchy foods at temperatures above 250 F/121 C, the more acrylamide is produced.Acylamide in the Scientific LiteratureAnimal studies on acrylamide are the most worrisome to date. Rats and mice fed high levels of the substance in their drinking water were found by researchers to be at increased risk for several types of cancer. In people, studies on acrylamide in the diet have produced mixed results for some types of cancer including kidney, endometrial, and ovarian. Exposure to high levels of acrylamide in the workplace via inhalation or the skin has been shown to cause nerve damage, which can lead to numbness or weakness in the arms or legs, bladder problems, in addition to other symptoms.The limitation of the human studies on acrylamide in the diet thus far is that many of themrelied on food questionnaires which people filled out every couple of yearsthat maynot have accounted for all dietary sources of acrylamide. Moreover, food questionnaires are notorious for not being entirely accurate as people may not clearlyremember (or be willing to admit) what they have been eating over time.While more human studies need to be conducted on the effect of acrylamide on health, at the present time, caution should be exercised given that it definitely does produce cancer in animals. Heres what various leading government agencies have to say on the subject: The U.S. Food and Drug Administration has released a consumer warning on acrylamide to limit exposure given that it has been found to be carcinogenic in animals(2). CDC scientists found measurable levels of acrylamide in the blood of 99.9% of the U.S. population. Smokers have nearly twice the levels of acrylamide in their blood as nonsmokers (3). The World Health Organication (WHO)classifies acrylamide as a probable human carcinogen. This is based on data showing it can increase the risk of some types of cancer in lab animals. The WHO has not reviewed its position on acrylamide since 1997, and at that time, acrylamide was not known to be found in so many starchy foods at such high levels (4). The National Toxicology Program (NTP)concluded in its 2011 Report on Carcinogensthat acrylamide is reasonably anticipated to be a human carcinogen based on the studies in lab animals (5). The US Environmental Protection Agency (EPA) maintains the Integrated Risk Information System (IRIS), an electronic database that contains information on human health effects from exposure to various substances in the environment. The EPA classifies acrylamide as likely to be a carcinogen to humans based on studies in lab animals (6).The Good News: Traditional Cooking Minimizes Acrylamide in Food!If all this data on acrylamide has you depressed, cheer up! Knowledge of traditional diet not only provides the information about which healthy fats to cook with, but also how to safely prepare them!When I cook, even fry, starchy foods in our home, I have little concern for acrylamides. The trick is that you need to know how to prepare carbohydrate foods so that the chemical is minimized so that you dont get too much on a consistent basis. Obviously, traditional cultures were exposed to at least some acrylamide too and did just fine. Native American cultures smoked tobacco, for example, so at the very least, they were getting regular exposure this way.As a result, minimization of exposure is the key without getting extreme to the point where you never eat a fried food ever again. This just isnt realistic.Ways to Minimize Acrylamide in your Home CookingWhen I first started learning methods for reducing acrylamide in cooked foods, it was in conjunction with the research I was doing for my first book Get Your Fats Straight.My husband had an aha moment one evening when we were discussing the dangers of acrylamides in the diet given how many starchy, snacky foods Americans seem to be eating on a daily basis. For many Westerners, these types of foods serve as the mainstay of the diet. He mentioned that his mother, who is an expert in traditional cooking and raised her family on these methods, used to always blanch potatoes briefly in boiling water prior to frying or roasting them. As it turns out, this is exactly the method recommended by the National Cancer Institute to minimize acrylamide production in a food before you cook it!Obviously, the most important thing to know when avoiding acrylamides in the diet is to limit consumption of snacky, starchy foods that you buy at the store. Even if these foods are organic, they are made in a factory with the typical high heat, high pressure processing in most cases.Since acrylamide is formed from natural chemicals in food during cooking, this type of factory process will produce acrylamide levels in cooked organic foods that are likely similar to those in cooked nonorganic foods.If you want to enjoy french fries, be sure to make them at home as much as possible and be sure to blanch those potatoes first before immersing in the hot oil! Does this mean you should never eat fries in a restaurant? Not necessarily, just understand that the more you do this, the higher your acrylamide exposure.Boiling potatoes or other starchy foods, decreasing cooking time and drying foods in a hot air oven after cooking have also been shown via research to decrease the acrylamide content of some foods (7). Make that food thermometer your friend! This is the kitchen thermometer I use and purchased for about $10. I use it all the time to keep cooking temperatures as low as possible in my kitchen.Here are some very helpful additional tips for minimizing acrylamides in your cooking as suggested by the American Cancer Society: For potatoes, frying causes the highest acrylamide formation. Roasting potato pieces causes less acrylamide formation, followed by baking whole potatoes. Boiling potatoes and microwaving whole potatoes with skin on does not produce acrylamide. If blanching the potatoes isnt a good option for you prior to cooking, you can also just soak raw potato slices in water for 15 to 30 minutes before frying or roastingto reduce acrylamide formation when the potatoes are cooked. Be sure to drain and blot dry the soaked potatoes before cooking for safety reasons to prevent splattering or fires. Beware! Potatoes should never be stored in the refrigerator as this can result in increased acrylamide during cooking. Potatoes are best stored in a dark, cool place such as a closet or a pantry to prevent sprouting. Sprouted potatoes contain solanine, a poison found in nightshade vegetables that can bring on gastrointestinal or neurological symptoms when ingested. Acrylamide levels tend to rise when cooking occurs for longer periods and/or at higher temperatures. Taking care to cook cut potato products, such as frozen French fries or potato slices, to a golden yellow color rather than a medium to dark brown color helps reduce the formation of acrylamide considerably. Be sure to toast bread to a light brown color rather than a medium or dark brown color. Very brown toasted areas contain the most acrylamide. Maybe our kids have the right idea by not eating the crusts, which tend to be the toastiest parts of the bread! Acrylamide forms in coffee when coffee beans are roasted, not when coffee is brewed at home or in a restaurant. So far, scientists have not found good ways to reduce acrylamide formation in roasted coffee beans.Healthy home cooking doesnt just involve selecting the right foods, it also involves storing and preparing them properly.Sarah, The Healthy Home EconomistSources and More InformationNational Cancer Institute: Acrylamide in FoodAmerican Cancer Society: Acrylamide
