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

Like Wright’s imaginary fire, microwave ovens may shorten the period of time it takes to perform one other job: cooking our meals. They’ve proliferated rapidly 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 know-how, the meals trade has innovated tens of 1000’s of merchandise designed to work with the microwave oven. The microwave oven has turn into a lot of a default, that generally you need to experiment to determine find out how to cook dinner that frozen dish in boiling water or a pan or a toaster.

Microwave ovens have been broadly accessible since 1967, however the first microwave oven happened in 1946. A Raytheon-employed engineer named Percy Spencer used World War II radar know-how to unintentionally 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, practically each trendy dwelling, restaurant, workplace constructing, and motel room has a microwave oven in it.

But although microwaves have turn into a usually used equipment, the query stays: are they secure to make use of?

What are Microwave Ovens and How Do They Work?

Microwaves had been developed to cook dinner and warmth meals rapidly. 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 stop chilly spots.

Contrary to in style perception, microwaved meals don’t truly 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 in the end warmth. Since not all areas include the similar quantity of water, the heating is uneven. Because of this shortcoming, I don’t know lots of cooks who love microwaves, besides as a approach 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 fact could also be behind them.

Unhealthy Foods

The largest drawback with microwave ovens truly 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 persons 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 fact is, there’s a world of distinction between microwaving an industrially produced frozen TV dinner and steaming some contemporary 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 in case you use a microwave incorrectly. One rule of thumb is to by no means put aluminum foil or metallic 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 truly spark and harm the oven, and even lead it to catch fireplace. Food containers may get extremely popular; you possibly can burn your self in case you attempt to choose them up with out kitchen mitts or towels. If you’re cooking one thing in a lined container, you may find yourself with steam burns to your face as you take away the lid.

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


Cooking TV dinners or utilizing plastic wrap to reheat leftovers include their very own considerations. Many TV dinners truly 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 via a microwave oven after which had them examined in a lab. The containers included plastic sorts 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 turn into radioactive. Some individuals even discuss with cooking their meals in a microwave oven as “nuking” it. Quite merely, that is fallacious.

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 rules require that microwave ovens are sealed to stop high-level radiation leaks. Their web site notes that there’s little concern about radiation leakage until 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 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 may very well be lurking in uncooked meals might not be killed. This is principally a priority for meats, fish, and different high-risk, animal-derived merchandise, which have to be heated to at the very least 140°F to kill pathogens, a few of which can even be immune to antibiotics.

Cancer-Causing Compounds?

Yet one other concern round microwaving animal meals was raised by a 2015 research revealed 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 could scale back a few of the dietary high quality of sure meals when in comparison with different cooking strategies. For instance, a 2004 research revealed 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 lots of 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 approach to put together (or at the very least, to warmth) many meals. In most instances, the greatest approach to cook dinner your greens is the one which will get you to eat them, and for some individuals, based mostly purely on comfort, that could be in a microwave oven.

These ovens are additionally simple to wash — a lot more-so than a traditional oven — so long as you observe 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 revealed 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 totally 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 vital impression on antioxidant exercise in greens. To be clear, the distinction right here just isn’t big, however it may very well be a degree in the microwave oven’s favor.

Another perk to microwaving meals is that it doesn’t warmth up your home like standard ovens do. Have you ever made baked items or a casserole dish in the heat months? A standard oven will warmth up your total kitchen, which can be good in the winter, however it 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 essential.

The Bottom Line

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