Goodbye to the microwave: a study warns of the danger of using it to cook potatoes

The microwave is the household appliance par excellence of our time: in a world where convenience and speed are increasingly necessary when cooking, the use of microwave It has become the daily bread for millions of homes. However, a recent study by researchers from the University of Almería and published in the journal Food Chemistry has shed light on possible risks associated with this convenient way of cooking.

This device is an appliance that passes all controls, which is perfectly reviewed and has survived several hoaxes (such as the one about microwave waves causing cancer). But, in light of the latest discoveries, its incorrect use is not without risks either.

Risks of cooking potatoes in the microwave

This group of researchers has discovered that the simple act of heat potatoes in plastic containers designed for microwaves can trigger the formation of an unknown and potentially dangerous chemical substance. This new substance arises from the interaction between the natural components of potatoes and the plastic materials present in the packaging when they are subjected to high temperatures during the microwave cooking process.

But that is not all. The investigation also reveals another worrying finding: Polypropylene polymers, commonly used in the manufacture of plastic microwave containers, can migrate into foods more easily during cooking. This migration of polypropylene can lead to the release of chemicals that, once ingested, could pose a health risk.

So what does all this mean for the consumers concerned about their health and food safety? First, it is important to understand the potential risks associated with using plastic microwave containers. Although these containers are designed to be safe for use in microwaves, exposure to high temperatures can trigger unforeseen chemical reactions that could affect the safety of the food.


As a precautionary measure, it is strongly recommended avoid heating potatoes or other foods in plastic microwave containers, especially those containing polypropylene. Instead, it is suggested to use glass or ceramic containers that are safe for use in the microwave. These materials offer a safer and more reliable alternative to cooking food in the microwave.

Furthermore, it is essential read and follow the manufacturer’s instructions regarding the proper use of plastic microwave containers. Some containers may be safer than others for microwave use, so it’s important to pay attention to the manufacturer’s specific recommendations.

Protecting our health begins in the kitchen. Let’s take proactive measures to avoid exposure to potential chemical risks by cooking our food safely and responsibly. By choosing safer cooking practices and using appropriate packaging materials, we can reduce the risk of exposure to harmful chemicals and ensure the safety of our food and families.
