There is no evidence that they cause harm — and some evidence that they are even better than other cooking methods at preserving nutrients and preventing the formation of harmful compounds.

Some nutrients break down when they're exposed to heat, whether it is from a microwave or a regular oven. Vitamin C is perhaps the clearest example. But because microwave cooking times are shorter, cooking with a microwave does a better job of preserving vitamin C and other nutrients that break down when heated.
As far as vegetables go, cooking them in water robs them of some of their nutritional value because the nutrients leach out into the cooking water. For example, boiled broccoli loses glucosinolate, the sulfur-containing compound that may give the vegetable its cancer-fighting properties as well as the taste that many find distinctive, and some find disgusting. Is steaming vegetables — even microwave steaming — better?
But most experts agree that heating plastic with phthalates can increase exposure. Phthalates have been found to disrupt hormones and our metabolic system Credit: Getty Images. The best ways to minimise risk are to use other microwave-safe materials than plastic, such as ceramic. If you do use plastic containers, avoid any that are losing their shape, since old and damaged containers are more likely to leach chemicals. Even if you avoid plastics, there are other potential risks of heating food in the microwave — including uneven heating, and the high temperatures used.
First, consider using microwaves to reheat, rather than cook, food, as it may cook unevenly. The high temperatures of the microwave may also pose some risk. When Betty Schwartz, professor of nutritional sciences at theHebrew University of Jerusalem, saw her students heating jacket potatoes in the microwave on their lunchbreaks, she noticed small crystals inside their potatoes.
When she analysed them, she found they were high in the chemical acrylamide, which can be a natural by-product of cooking. There is some research to suggest that microwaves are more favourable to the growth of acrylamide than other methods of cooking.
One way around this is to soak the potatoes in water before putting them in the microwave. As for the radiation in microwaves, it is completely harmless. Microwaves use low frequency electromagnetic radiation — the same kind used in lightbulbs and radios.
When you put food inside a microwave, it absorbs these microwaves, which makes water molecules in the food vibrate, causing friction that heats up the food. In a Swiss clinical study , researchers found that blood changes in individuals who consumed microwaved milk and vegetables. The eight participants in the study ate a series of food prepared in different ways, including food heated in the microwave.
The results of the study showed red blood cells decreased while white cell levels increased, along with cholesterol levels. The non-ionizing radiation of the microwave can affect changes in your blood and your heart rate. Microwaves can produce effects on your body instantly due to the 2. A study conducted by Dr. Magda Havas of Trent University found the levels of radiation emitted by a microwave affect both heart rate and heart rate variability.
These levels are within federal safety guidelines but tend to cause immediate and dramatic changes in heart rate. If you experience irregular heart beat or any chest pain and regularly eat microwaved food, it might be best to discontinue use.
Years of research suggest that vision, lung function, immune system performance, and even sperm count can all be improved by omega-3s. Do you know how to prevent head lice infestations? Or what to do if you find the critters?
