The microwave has become an indispensable part of modern kitchens, offering a quick and convenient way to reheat meals and cook a variety of dishes. However, despite its widespread use, microwaving can be dangerous if not used properly. In fact, there are certain foods and items that should never be microwaved due to the risk of explosions, fires, nutrient destruction, and even health hazards.
The Science Behind Microwaving
Before we dive into the 5 things you should never microwave, it’s essential to understand how microwaves work. Microwaves use non-ionizing radiation to heat food and liquids. When you press the start button, the microwave produces electromagnetic waves that penetrate the food, causing the water molecules in the food to rotate back and forth. This rotation generates heat, which is then distributed throughout the food through conduction and convection.
While microwaves are designed to cook food quickly and efficiently, they can also cause hotspots, nutrient destruction, and even create harmful chemicals. This is why it’s crucial to use your microwave wisely and avoid nuking certain foods and items.
1. Eggs
Eggs should never be microwaved whole, as they can explode and cause serious injuries. This is because the egg whites and yolks heat at different rates, causing the egg to build up pressure and eventually burst. When this happens, the result can be messy and even dangerous.
Even if you’re just trying to cook an egg for a few seconds, it’s still not recommended. Microwaving an egg can cause the yolk to become superheated, which means it can reach temperatures above its boiling point. When you crack open the egg or remove it from the microwave, the yolk can explosively boil, causing hot egg yolk to splatter everywhere.
The Dangers of Superheated Eggs
Superheated eggs are not just a messy inconvenience; they can also cause serious burns. When the egg explodes, the hot yolk can splash onto your skin, causing second-degree burns. In some cases, the burns can be severe enough to require medical attention.
Instead of microwaving eggs, it’s better to cook them conventionally on the stovetop or in the oven. This allows you to cook the eggs at a lower temperature and reduces the risk of explosion.
2. Metal Containers

The danger of microwaving metal containers is not limited to just sparks and fires. When metal is heated in a microwave, it can also cause the development of electromagnetic fields, which can interact with the human body. This can lead to a range of health problems, including headaches, fatigue, and even cancer.
The Risks of Electromagnetic Fields
Electromagnetic fields (EMFs) are a type of radiation that is emitted by microwaves, cell phones, and other electronic devices. While the risks of EMFs are still being studied, research suggests that prolonged exposure can cause a range of health problems, including:
- Headaches and fatigue
- Cancer and tumors
- Neurological damage
- Cardiovascular disease
To avoid the risks of microwaving metal containers, make sure to use only microwave-safe containers. These containers are specifically designed to withstand the high temperatures and electromagnetic fields generated by microwaves.
3. Breast Milk or Formula
Microwaving breast milk or formula can destroy vital nutrients and create harmful chemicals. This is because microwaves can heat the milk or formula unevenly, creating hotspots that can destroy delicate nutrients.
When breast milk is microwaved, the proteins, vitamins, and antibodies can become denatured, making them ineffective or even harmful to the baby. This can lead to a range of health problems, including digestive issues, allergies, and even developmental delays.
Microwaving formula can also create harmful chemicals, including carcinogenic compounds like heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs). These chemicals have been linked to an increased risk of cancer and other health problems.
The Importance of Proper Heating
Instead of microwaving breast milk or formula, it’s better to heat it gently using a bottle warmer or by running it under warm water. This helps to preserve the delicate nutrients and avoids the creation of harmful chemicals.
4. Plastic Containers
Microwaving plastic containers can release harmful chemicals and cause the plastic to warp or melt. This is because many plastic containers are not designed to withstand the high temperatures generated by microwaves.
When plastic containers are heated in a microwave, the plastic can release harmful chemicals like bisphenol A (BPA) and phthalates. These chemicals have been linked to a range of health problems, including hormonal imbalances, cancer, and reproductive issues.
The Dangers of BPA and Phthalates
BPA and phthalates are two of the most common chemicals found in plastic containers. These chemicals can leach into food and drinks when heated, causing a range of health problems. Some of the risks associated with BPA and phthalates include:
- Hormonal imbalances and reproductive issues
- Cancer and tumors
- Neurological damage and developmental delays
- Cardiovascular disease and metabolic disorders
To avoid the risks of microwaving plastic containers, make sure to use only microwave-safe containers. Look for containers that are labeled as “microwave-safe” or “BPA-free.”
5. Water
Microwaving water can cause it to become superheated, leading to explosions and injuries. When water is heated in a microwave, it can become superheated, which means it can reach temperatures above its boiling point. When the water is removed from the microwave or disturbed, it can explosively boil, causing hot water to splatter everywhere.
The risks of microwaving water are not limited to just explosions. Superheated water can also cause serious burns, as the hot water can splash onto your skin. In some cases, the burns can be severe enough to require medical attention.
The Dangers of Superheating
Superheating is a common phenomenon that occurs when water is heated in a microwave. When water is heated, the molecules on the surface are able to escape, creating a layer of cooler water on top. This can cause the water to become trapped, leading to a buildup of pressure and eventually, an explosion.
To avoid the risks of microwaving water, it’s better to heat it conventionally on the stovetop or in a kettle. This allows you to heat the water at a lower temperature and reduces the risk of superheating.
Conclusion
Microwaves can be a convenient and quick way to cook and reheat food, but they can also be dangerous if not used properly. By avoiding the 5 things you should never microwave, you can reduce the risk of explosions, fires, nutrient destruction, and even health hazards.

What is the main concern with microwaving food?
The main concern with microwaving food is that it can lead to a loss of nutrients, uneven heating, and the creation of harmful compounds. Microwaves use non-ionizing radiation to heat food, but this process can break down the molecular structure of nutrients, making them less effective or even toxic. Additionally, microwaves can heat food unevenly, leading to hotspots that can burn or overcook certain areas, while leaving other areas undercooked.
Furthermore, microwaving can also lead to the formation of carcinogenic compounds, such as acrylamide, which is formed when starchy foods like potatoes and bread are heated to high temperatures. These compounds can accumulate in the body over time, increasing the risk of cancer and other health problems. Therefore, it’s essential to be mindful of what you microwave and how you microwave it to minimize these risks.
Is it true that microwaving breast milk can destroy its nutrients?
Yes, microwaving breast milk can destroy its nutrients and even create toxic compounds. Breast milk contains delicate antibodies and enzymes that are essential for a baby’s health and development. When microwaved, these nutrients can become denatured, losing their effectiveness or even becoming toxic. In fact, a study published in the Journal of Nutrition found that microwaving breast milk can destroy up to 98% of its immunoglobulins, which are vital for a baby’s immune system.
Therefore, it’s recommended to thaw or warm breast milk by placing the bottle in a bowl of warm water or running it under warm tap water. Breast milk should never be microwaved, as this can have serious consequences for a baby’s health. If you’re unsure about the safety of microwaving breast milk, it’s always best to err on the side of caution and use a safer warming method.
