Is microwaving food in plastic really harmful to my health?

The dioxins in the plastics we microwave are pretty harmless, because quite simply, they don’t exist in plastic. There is essentially no evidence that there are dioxins in these plastic materials, says Halden. That’s right – nada — which means when heated in the microwave, it’s next to impossible for them to be released.

Is there metal that is microwave safe?

Many metal pots and pans have plastic handles made of phenolic, which may explode if placed in the microwave. There are, however, pots and pans made specifically for use in the microwave that are made of metal. These are usually labeled as Microwave Safe, and can be used for a wide range of cooking.

What does the recycling symbol 7 mean?

Plastics that have the recycling symbol "7" usually contain higher levels of BPA and plastics marked with the recycling number "3" are more likely to contain phthalates. But because these markings aren’t used to indicate the additives in plastic, they can’t really be relied upon to tell if or how much BPA and phthalates plastics contain. (There’s no consensus, for example, on whether "5" plastics contain BPA.)

What are phthalates used for?

Phthalates, on the other hand, are used in plastics to make them soft and pliable (think rubber duckies). Both BPA and phthalates are believed by many scientists to be endocrine disruptors, sometimes called hormone disruptors.

What hormones are BPA and phthalates usually suspected of disrupting?

The hormone that BPA and phthalates are usually suspected of disrupting is estrogen. It’s been linked to obesity in some research. 1 ? And male fetuses exposed to high levels of estrogen may develop with birth defects including hypoplasia (a displaced urethra).

How to avoid phthalates and BPA?

The first and best way to avoid phthalates and BPA is to use food containers that don’t contain these compounds: glass, metal, and other containers are longer-lasting and–in the case of glass–can usually be microwaved.

What are the two additives that are harmful to humans?

Two additives, however, stand out among toxicologists as potential human health hazards: bisphenol-A, or BPA, and phthalates. BPA is an additive used to make hard, clear plastics (such as CDs and water bottles).

Where are BPA and Phthalates found?

BPA and Phthalates in Food. Though BPA and phthalates are found everywhere– BPA is even in many cash register receipts–most human exposure is thought to occur through food. Both plastic additives are in food containers, some plastic wraps, and in the linings of food and drink cans.

Can you tell if plastic has BPA?

But because these markings aren’t used to indicate the additives in plastic, they can’t really be relied upon to tell if or how much BPA and phthalates plastics contain. (There’s no consensus, for example, on whether "5" plastics contain BPA.)

How To Tell If Plastic is Microwave Safe?

There are many ways to check if a plastic container is microwave safe.

What is a microwave safe stamp?

So a microwave-safe stamp can ensure the consumers that a particular plastic container can withstand the microwave heat waves. 2. Use the Recycling Code as a Guide. The number that show see between a triangle embossed on a plastic container is its recycling number.

What does it mean when a microwave container does not contain a label?

It simply means that they have not gone through the testing that would determine if they are safe or not.

What does the microwave symbol mean?

The symbol with microwave and wavy lines indicates that particular cookware is safe to be put inside the microwave. You can look for the symbol on the bottom of a container. Microwave-safe containers are gone through rigorous testing and approved by the FDA to designate a particular container is safe to be used in a microwave.

How does microwave work?

As we mentioned above, microwave waves work by stirring the molecules of food. The microwave-safe containers do not absorb the heat waves but allow them to pass through to the food inside. An easy way to determine if a container is microwave-safe is to place it in a microwave with water in it for half a minute.

What is polyester used for?

Most common plastic of polyester family. It is used in clothing, food containers and plastic bottles.

What is the code for polypropylene?

Polypropylene – Recycle Code 5. A Typical Polypropylene Container. It’s a thermoplastic polymer. It has a high density and can resist heat. A common type of polypropylene is baby bottles and plastic cups. These containers are best to be used in the microwave if you want to use plastic anyway.

Why Are Some Plastics Unsuitable for Microwaving Food?

When plastics are heated, microscopic amounts of material may be absorbed by the food against the plastic. In most cases, this is completely safe and in such minuscule amounts it may not even be detectable.

What About Bisphenol A (BPA)?

You may have heard that plastics with BPA may be unsafe. Because of increasing public concern about BPA, the Food and Drug Administration (FDA), which governs food safety in the US, has undertaken multiple, extensive studies on BPA.

Plastics to Avoid When Microwaving Food

These plastic formulations (listed with their recycling numbers) may perform poorly in the microwave and may interact more with your food, particularly greasier foods. They should only be used in the microwave if they have the microwave-safe label.

Safe Plastics to Microwave Food

Despite the often alarming headlines and stories online, using plastics labeled "microwave-safe" is a simple, convenient, and safe way to heat or reheat foods.

Is Number 5 Plastic Microwave Safe?

Type 5 polypropylene is most often considered the safest plastic to use in the microwave. The chemical structure of Type 5 plastic makes it perfectly suitable for microwave use. It can withstand high temperatures and doesn’t leach out chemicals like BPA (bisphenol A), which has been linked to reproductive and immunity problems, as well as neurological and developmental issues in children.

Is It Safe to Microwave Plastic?

However, not all plastics are the same. Some can be more prone to certain chemicals leaching out than others, and that’s a big problem because it means some of the plastic could make its way into your food.

What is The Best Way to Microwave Food?

Personally, I prefer to transfer cold foods or beverages that I want to heat to a container made out of microwavable material like ceramic and glass. I believe this is the safest way to microwave your food. Not only does it take away the risk of chemicals leaching out into your food, but it also lowers the risk of burns since there is no plastic involved.

However, as mentioned before, the exception to this rule is type 5 plastic, which is considered microwave safe and BPA free.

Is PP plastic safe to use?

PP is the safest plastic for reuse. It does not contain plasticizers or additives that could leach out when it is heated in the microwave, washed in the dishwasher, or left under the sun.
