How do microwaves cook food?
microwaves work by uniolated radiation, creating microwaves that vibrate water molecules in food and generate heat, thereby cooking food. According to Brittany Lubeck, a nutritionist at the University of Wisconsin (USA), microwaves do not cause food to be contaminated with radiation or genetic modification, because this type of radiation does not have enough energy to break down DNA like ionized radiation.
Thanks to this principle, foods high in water such as vegetables often heat up faster, while dishes high in fat or sugar take longer to cook evenly. However, uneven heating can still happen if the amount of food is too large or placed in the wrong position.
Maintain nutrients better than boiling or frying
One common misconception is that microwaves deplete nutrients in food. In fact, according to many studies, cooking or heating with microwaves helps preserve vitamins and minerals better than traditional methods.
Driver microwaves cook quickly at lower temperatures, helping to limit the loss of water-soluble vitamins such as C and group B, Lubeck added. A study published in the Journal of Food Science also showed that microwave-cooked vegetables retain more vitamin C than boiled or stewed.
In particular, the short heating process also increases the amount of resistant starch and antioxidants in some foods, supporting digestion and protecting cells from oxidative damage.
Use properly to avoid health risks
Although safe, microwaves can still pose risks if used incorrectly. The US Food and Drug Administration (FDA) recommends that consumers check the device regularly to avoid radiation leakage in old or damaged machines.
Also, absolutely do not use thin plastic boxes or signs of being unsafe for microwaves, because heat can melt and release toxic chemicals into food. Use specialized porcelain, glass or plastic items certified as microwave Safe.
Another note is to let the food rest for a few minutes after heating, because the cooking process continues, helping to heat evenly and killing the remaining bacteria.
microwave, when used properly, is not only safe but also helps preserve nutrients better. The important thing is that users need to clearly understand the operating mechanism and follow safety instructions to be both convenient and ensure long-term health.
