Comedian Steven Wright as soon as mentioned, “I just bought a microwave fireplace. You can spend an evening in front of it in only eight minutes.”

Like Wright’s imaginary hearth, microwave ovens can even shorten the period of time it takes to perform one other process: cooking our meals. They’ve proliferated shortly since their industrial introduction in the late 1960s, a lot in order that it’s now exhausting for many people to think about a kitchen with out one.

And together with the expertise, the meals trade has innovated tens of 1000’s of merchandise designed to work with the microwave oven. The microwave oven has change into a lot of a default, that typically you must experiment to determine tips on how to cook dinner that frozen dish in boiling water or a pan or a toaster.

Microwave ovens have been extensively obtainable since 1967, however the first microwave oven happened in 1946. A Raytheon-employed engineer named Percy Spencer used World War II radar expertise to by chance produce the first microwave cooking oven, with which he melted a sweet bar. Before lengthy, Spencer was utilizing his microwave to pop popcorn, which turned out to be a prescient alternative: popcorn remains to be the hottest microwaved meals.

Over the subsequent few many years, microwave ovens advanced to incorporate a turntable and to be extra inexpensive and relevant for on a regular basis client use. And at the moment, almost each trendy house, restaurant, workplace constructing, and motel room has a microwave oven in it.

But though microwaves have change into a repeatedly used equipment, the query stays: are they protected to make use of?

What are Microwave Ovens and How Do They Work?

Microwaves had been developed to cook dinner and warmth meals shortly. They’re named for the electromagnetic waves that they produce — microwaves — that are longer than infrared radiation, however shorter than radio waves. The equipment makes use of a glass turntable to rotate meals because it cooks, which helps to forestall chilly spots.

Contrary to in style perception, microwaved meals don’t really cook dinner from the inside out. Microwave cooking begins inside the molecules the place water is current, and twists these molecules forwards and backwards to supply friction and finally warmth. Since not all areas include the identical quantity of water, the heating is uneven. Because of this shortcoming, I don’t know numerous cooks who love microwaves, besides as a option to heat up issues that had been already beforehand cooked.

Cons of Using Microwave Ovens

Let’s first tackle a few of the considerations round utilizing microwaves and the way a lot reality could also be behind them.

Unhealthy Foods

The largest drawback with microwave ovens really isn’t the home equipment themselves, however the poor meals that all-too-often accompany them. With our busy, on-the-go society, most of what individuals are utilizing microwaves for is to cook dinner or warmth ultra-processed, food-like merchandise that don’t do your well being any favors. But in actuality, that’s not the oven’s fault. The reality is, there’s a world of distinction between microwaving an industrially produced frozen TV dinner and steaming some recent or frozen broccoli.

Improper Use

In addition to what’s being put into the microwave oven, improper use of the equipment itself will also be problematic. You can injure your self when you use a microwave incorrectly. One rule of thumb is to by no means put aluminum foil or steel pans in a microwave oven as the waves can be mirrored off of them. This not solely causes meals to cook dinner erratically, however can really spark and harm the oven, and even lead it to catch fireplace. Food containers can even get highly regarded; you’ll be able to burn your self when you attempt to decide them up with out kitchen mitts or towels. If you’re cooking one thing in a coated container, you would possibly find yourself with steam burns to your face as you take away the lid.

Every day, about 21 folks find yourself in American emergency rooms from “microwave oven-related injuries.” There are a couple of from microwave popcorn steam, overheated hair elimination wax, and almost one a day from exploding eggs (ensuing from the strain buildup of inside steam), however most are from overheated water. The FDA warns to watch out when making an attempt to boil water in a microwave oven — notably when dumping one thing into it.


Cooking TV dinners or utilizing plastic wrap to reheat leftovers include their very own considerations. Many TV dinners really instruct you to cook dinner them with the plastic wrap nonetheless intact. But when plastic is heated, poisonous chemical substances like BPA and phthalates can leach out of the containers or covers, contaminating your meals with endocrine disruptors.

In 2008, the Milwaukee Journal Sentinel put 10 “microwave safe” containers by way of a microwave oven after which had them examined in a lab. The containers included plastic varieties 1, 2, 5, and seven. Bisphenol A, or BPA, was discovered to be leaching from all of them. The quantities detected had been at ranges that may trigger neurological and developmental harm in laboratory animals.

Frederick vom Saal, a University of Missouri researcher who guided the newspaper’s testing, commented: “There is no such thing as safe microwaveable plastic.”


But what about if microwave ovens are used safely — with meals which can be cooked in, for instance, glass containers with glass lids? Are microwaves inherently harmful, or is the drawback merely how they’re getting used?

The World Health Organization notes that considered one of the largest myths about microwave ovens is that meals cooked in them change into radioactive. Some folks even confer with cooking their meals in a microwave oven as “nuking” it. Quite merely, that is flawed.

But microwave ovens do emit a kind of microwave radiation. These “microwaves” are just like mild in how they behave; as soon as in transit, they’re both mirrored or absorbed by supplies of their path. How does this relate to client well being? According to the FDA, which has been regulating microwaves since 1971, radiation-related accidents are very uncommon. Cases are sometimes the results of improperly serviced home equipment that led to overexposure of leaked microwaves. FDA laws require that microwave ovens are sealed to forestall high-level radiation leaks. Their web site notes that there’s little concern about radiation leakage except your microwave has any harm to its door seal, latch, or hinges. If your microwave continues to run with its door open, the FDA recommends now not utilizing it, as this might trigger radiation to leak out.

Undercooked Food

But there’s one other trigger for concern: Microwaves can’t at all times be trusted to cook dinner meals homogeneously. Foods undercooked in microwave ovens can pose public well being dangers since the pathogens that could possibly be lurking in uncooked meals might not be killed. This is especially a priority for meats, fish, and different high-risk, animal-derived merchandise, which must be heated to a minimum of 140°F to kill pathogens, a few of which can even be proof against antibiotics.

Cancer-Causing Compounds?

Yet one other concern round microwaving animal meals was raised by a 2015 research printed in the Journal of Food Processing and Preservation, which discovered that extra cancer-causing heterocyclic fragrant amines (HCA) had been created in meat when microwaved than when it was pan-fried, baked, and even barbecued.

Possible Nutrition Loss

And there are considerations that microwaving meals might scale back a few of the dietary high quality of sure meals when in comparison with different cooking strategies. For instance, a 2004 research printed in the International Journal of Food Sciences and Nutrition discovered that protein from microwave-cooked legumes was 5% much less digestible than the protein from legumes that had been cooked in a strain cooker. More dramatically, a 2003 research discovered that microwave-cooked broccoli misplaced as much as 97% of its helpful flavonoids, in comparison with solely an 11% discount when the broccoli was steamed. Another research discovered microwave heating time of 60 seconds was lengthy sufficient to deactivate the cancer-fighting compound alliinase in garlic.

Pros of Using Microwaves

There are additionally numerous perks to having microwave ovens so available to us. If there weren’t, we wouldn’t be utilizing all of them the time.

Microwave ovens are nearly the quickest and best option to put together (or a minimum of, to warmth) many meals. In most circumstances, the greatest option to cook dinner your greens is the one which will get you to eat them, and for some folks, based mostly purely on comfort, which may be in a microwave oven.

These ovens are additionally straightforward to wash — a lot more-so than a traditional oven — so long as you comply with instructions and forestall splatter or explosions.

Some analysis has additionally discovered that greens cooked in the microwave retain extra antioxidants than these cooked by way of different strategies. A 2009 research printed in the Journal of Food Science checked out the impact of boiling, microwaving, pressure-cooking, griddling, frying, and baking on the antioxidant exercise of 20 completely different greens. Overall, they discovered that griddling, microwave cooking, and baking resulted in the smallest antioxidant losses. Cooking strategies that used water had a extra important affect on antioxidant exercise in greens. To be clear, the distinction right here will not be enormous, but it surely could possibly be a degree in the microwave oven’s favor.

Another perk to microwaving meals is that it doesn’t warmth up your own home like typical ovens do. Have you ever made baked items or a casserole dish in the heat months? A standard oven will warmth up your whole kitchen, which can be good in the winter, but it surely makes a scorching summer time day even sweatier. And in comparison with a traditional oven it saves power, which in at the moment’s world is vital.

The Bottom Line

Most microwave customers put plastic and ultra-processed meals of their ovens, thus exposing themselves to a number of chemical substances believed to contribute to most cancers, coronary heart illness, endocrine disruption, and lots of different illnesses.

And analysis remains to be ongoing on whether or not or not the EMFs and radiation emitted from microwave ovens current long-term well being risks. We don’t know that they do. And that doesn’t imply we’re sure that they don’t.
