A dietician has revealed the four common foods that should never be reheated in the microwave. 

If you've ever opened your fridge, grabbed some leftovers, and popped them into the microwave, you may have been putting yourself at severe risk without even knowing it - or completely ruining the dish.

That's right, according to nutritionist Amanda Holtzer, from New Jersey, there are some popular foods that many people don't realize are dangerous to heat up in the microwave.

In addition, she said there are many products that are perfectly safe to warm in a microwave, however, doing so might mess up their taste or texture.

Thankfully, the dietician broke down all of the food items that you should avoid putting in the microwave to Fox News.

First, she explained that hard-boiled eggs are a big no-no when it comes to heating in a microwave.

Why? Well, they can actually explode when you bite into them due to built-up pressure, which can lead to potential burns. 

'Never microwave a hard-boiled egg,' she warned. 'Doing so causes steam and pressure to build in the egg white - and can lead to an eruption when the egg is cut into.

'This eruption can happen in the microwave, on your plate or, frighteningly, in your mouth when you bite into the egg.' 

Four foods you should never reheat in a microwave

  • Hard-boiled eggs
  • Foods high in vitamin C
  • Chicken
  • Fish 

She also advised against putting any food items that are rich in vitamin C, like broccoli, brussels sprouts, and potatoes, into the microwave.

'When exposed to heat, vitamin C is degraded and destroyed,' she explained. 

'To maintain the integrity of the vitamin C in these foods, I recommend consuming them raw as often as possible.' 

Next on Amanda's list was chicken, as she said reheating it can result in it having an 'off taste and texture.'

She dished, 'When chicken is stored in the refrigerator after cooking, the fats in the meat can oxidize, which can change the chemical structure of the chicken and therefore the taste.

'Then, when reheated, any moisture that was in the chicken evaporates, thus leaving you with chicken that has both an off taste and texture.' 

She also said it's not ideal to microwave fish, as the high temperature can 'cause the moisture in fish to evaporate, resulting in a very dry, rubbery texture.' 

In addition, she said there are many products that are perfectly safe to warm in a microwave, however, doing so might completely mess up their taste or texture

Last month, a scientist revealed the alarming reason why you should 'never, ever' eat food that's been microwaved in plastic containers

Dr. Shanna Swan is a respected expert on substances called endocrine disruptors, which are those that wreak havoc on the body's hormones and, as a consequence, our reproductive health. 

Speaking on popular health podcast Huberman Lab, the epidemiologist urged people against microwaving food in plastic containers due to the risk of these chemicals leaching into food. 

'The BPA, the phthalates, the plasticisers are added to the plastic but they're not chemically bound to it,' she said. 

'So if you put anything in a container that has these chemicals in it and then put it in a hot environment they will come out of the plastic and go into the food.' 

BPA, short for bisphenol A, and phthalates are sometimes adding to plastics as part of the manufacturing process to make them more durable.

Multiple studies link consumption of these chemicals to fertility issues, though regulators say current evidence suggests the level of exposure the average person faces in day-to-day life is safe.
