myth bout microwave

the older generations in my family always said that microwave is bad for health and stuff. they kinda even claim that microwave actually make your food become poisonous. yet, is it true??
i always wanted to check it out but didn't manage to.

microwaves work by using high-frequency radio waves (called microwaves) to make the molecules in your food move very fast, creating heat. what makes microwaves so effective is that the radio waves they emit have the ability to pass through paper, plastic and glass while being absorbed by food. as scary as that may sound, it doesn’t necessarily mean that your food is radioactive after you’ve heated it up.

there are two main types of radiation: ionizing and non-ionizing.
ionizing radiation is the kind of radiation you come into contact with when you have an X-Ray or the type that’s used in nuclear power plants + can be dangerous if you receive large doses of it because it has the ability to change your DNA and damage your body. it can cause cancer to occur in your cells, for example, and can result in birth defects if you’re pregnant.
microwaves produce non-ionizing radiation and non-ionizing radiation doesn’t have the power to change your DNA and is not as dangerous as ionizing radiation.
but if you suspect that your microwave cover ain't properly seal, please stop using it and dispose it.

the Real Microwave Danger is Superheating. what is superheating?? Superheating occurs when liquids are quickly heated to a temperature that’s higher than its normal boiling point. when this happen, the liquid is heated up so fast that it doesn't has the time to change to vapour. hence it is pretty unstable. if addition energy, for example, if you stir it, it'll erupt as the steam suddenly break free!!

there's another threat which microwave offer, killing the nutrients.
this is not particularly true.
in general, the nutritional value of microwaved food over conventionally cooked food has less to do with the cooking method itself and more to do with the type of food that is cooked. studies have shown that nutrients start to diminish in food that is over-cooked, whether in a microwave or on the stove + some research has shown that microwaving food for the correct period of time actually preserves the nutrients because of the short amount of time that it’s cooked.

so, is microwave bad?? did microwave make your food poisonous??
if you use the microwave correctly, its actually an awesome cooking equipment.
however, it does possesses a high degree of danger, that is if you avoid the advice given while using it.
