The use of a microwave oven does not present any risk to health. The health authorities have been guaranteeing its safety for years and it can be used daily to heat and cook food with complete peace of mind.
Always use microwave-safe containers and do not exceed the re
commended cooking times so as not to overheat the food. Microwaves can be used for both heating and cooking food, representing a cooking method that has advantages over traditional systems: it minimises cooking time, is clean and preserves the nutrients of the food in a slightly higher proportion than other cooking methods.
