Microwaves cause water molecules in food to vibrate, producing heat that cooks the food. That keeps in more vitamins and minerals than almost any other cooking method and shows microwave food can indeed be healthy. Baby bottles heated in the microwave can leach dangerous toxins into breast milk or formula. Microwaving can significantly alter levels of vitamins and nutrients that you need for a healthy body. The instructions that come with each microwave oven indicate the kinds of containers to use. The microwave energy is changed to heat as it is absorbed by food, and does not make food “radioactive” or "contaminated.". Microwaves have three characteristics that allow them to be used in cooking: they are reflected by metal; they pass through glass, paper, plastic, and similar materials; and they are absorbed by foods. In addition, the FDA requires that all ovens have a label explaining precautions for use. Send us your questions to letters@scienceillustrated.com.au. http://pubs.acs.org/cgi-bin/abstract.cgi/jafcau/1998/46/i01/abs/jf970670x.html. By choosing other methods to cook and store your food, you can be sure that your food will retain nutrients and be toxin-free. 14, pp. Superheating will also only happen if the water is microwaved for an excessively long time, far longer than is actually needed to heat the water (2-3 minutes). Have Radiation Injuries Resulted from Microwave Ovens? Use microwave safe cookware specially manufactured for use in the microwave oven. The water can also explode if you add a powder, such as coffee, or an object to stir it. 4 Natural Ways to Turn Back Time, Add These Fiber-Rich Foods to Your Diet to Fight…, About Donna Gates – Nutrition & Gut Health Expert, The Gut Recovery / Body Ecology 101 Masterclass. This is an excellent probiotic, I drink it daily. A special microwave oven cleaner is not necessary. At one time there was concern that radiation leakage from microwave ovens could interfere with certain electronic cardiac pacemakers. Microwaves are produced inside the oven by an electron tube called a magnetron. Microwaving foods may preserve more vitamins than boiling, for example, but that does not make it a safe and nutritious cooking choice. This stainless steel kettle heats your water so fast that you won’t even miss your microwave! Through its Center for Devices and Radiological Health (CDRH), the FDA sets and enforces standards of performance for electronic products to assure that radiation emissions do not pose a hazard to public health. http://findarticles.com/p/articles/mi_m1200/is_n17_v141/ai_12100730. Microwaves cause water molecules in food to vibrate, producing heat that cooks the food. This is especially important advice for mothers who are currently heating their baby’s bottle in the microwave. If we publish the answer on our website or in the next issue of Science Illustrated you could win amazing prices! Industry uses microwaves to dry and cure plywood, to cure rubber and resins, to raise bread and doughnuts, and to cook potato chips. Stop using a microwave oven if it continues to operate with the door open. Glass, paper, ceramic, or plastic containers are used in microwave cooking because microwaves pass through these materials. The Food and Drug Administration (FDA) has regulated the manufacture of microwave ovens since 1971. In fact, foods cooked in a microwave oven may keep more of their vitamins and minerals, because microwave ovens can cook more quickly and without adding water. Many mothers already know that microwaves heat liquids unevenly, so milk heated in the microwave could have hot spots that scald your baby. Refer to the instruction manual for your oven. To make sure the standard is met, FDA tests microwave ovens in its own laboratory. This limit is far below the level known to harm people. Checking Ovens for Leakage and Other Radiation Safety Problems, How to Report Microwave Oven Radiation Safety Problems, Additional Information from FDA's Consumer Health Information Staff, Accidental Radiation Occurrence Report form, FDA Consumer Update: 5 Tips for Using Your Microwave Oven Safely. In addition, a monitoring system stops oven operation in case one or both of the interlock systems fail. Electromagnetic radiation spans a broad spectrum from very long radio waves to very short gamma rays. 0 Comments, Water becomes unstable if superheated in a microwave. Information on this website is provided for informational purposes only and is a result of years of practice and experience by the author. But in the absence of bubbles, the water can become superheated above 100 degrees. Many new mothers even heat up breast milk or formula in the microwave. The site is secure. Non-ionizing radiation does not have enough energy to knock electrons out of atoms. But in the absence of bubbles, the water can … Microwaves have been shown to affect foods in these ways:2. This requirement may be dropped if the manufacturer has proven that the oven will not exceed the allowable leakage limit even if used under the conditions cautioned against on the label. You may also report any suspected radiation-related problems or injuries to the FDA by completing and mailing the Accidental Radiation Occurrence Report form. The FDA also monitors appliances for radiation safety issues and has received reports of microwave ovens that appear to stay on – and operate – while the door is open. Did you know that your microwave might be a health hazard? What’s the Best Vegan Protein for a Race? If you have or suspect that you have a medical problem, contact your healthcare provider promptly. Raloff, Janet, “Microwaving can lower breast milk benefits,” Science News, 25 Apr 1992. Microwave containers are usually smoother than kettles or saucepans, so bubbles of air do not cling to the sides and the water doesn’t boil, causing it to become unstable. Microwaving water cause changes in its “structure or energy.” This one started out as one of those widely-circulated emails that described somebody’s granddaughter’s science fair experiment. Another risk when using microwaves is that cancer-causing compounds from plastic containers and plastic wrap can leach into your food.3, FDA science policy analyst Catherine Bailey says “When you microwave, it’s a good idea not to have the plastic touch the food.”4. Two areas of the body, the eyes and the testes, are particularly vulnerable to RF heating because there is relatively little blood flow in them to carry away excess heat. Consumers should take common sense precautions regarding handling of hot foods and beverages. In general, microwave oven radiation injuries are caused by exposure to large amounts of microwave radiation leaking through openings such as gaps in the microwave oven seals. If you are going for boiling water, like to make tea, then be sure you see it actually boil. Exposure to ionizing radiation can alter atoms and molecules and cause damage to cells in organic matter. Studies on the effects of microwaves have been quite controversial as microwave technology has evolved over the years. While FDA does not specifically require microwave ovens to carry warnings for people with pacemakers, this problem has largely been resolved as today’s pacemakers are designed to shield against such electrical interference. Additionally, the lens of the eye is particularly sensitive to intense heat, and exposure to high levels of microwaves can cause cataracts. Follow the manufacturer's instruction manual for recommended operating procedures and safety precautions for your oven model. Users should make sure that they do not exceed the recommended heating times when determining the best time settings to heat water to the desired temperature. Food Chem., 46 (1), 206 -210, 1998. For more consumer information on microwave oven radiation, contact the Staff of the Division of Industry and Consumer Education (DICE) by email at DICE@cdrh.fda.gov. Microwaves are a form of "electromagnetic" radiation; that is, they are waves of electrical and magnetic energy moving together through space. Regularly clean the oven cavity, the outer edge of the cavity, and the door with water and a mild detergent.
