Is microwave cooking unhealthy?
Microwaves are a safe, effective, and highly convenient cooking method. There is no evidence that they cause harm — and some evidence that they are even better than other cooking methods at preserving nutrients and preventing the formation of harmful compounds.
What are the negative effects of microwaves?
Microwave radiation can heat body tissue the same way it heats food. Exposure to high levels of microwaves can cause a painful burn. Two areas of the body, the eyes and the testes, are particularly vulnerable to RF heating because there is relatively little blood flow in them to carry away excess heat.
Which nutrients are destroyed by heat?
Nutrients escape from vegetables in two ways: by getting dissolved in the cooking water or by getting destroyed by heat. Water-soluble compounds (which include vitamin C and some B vitamins) are the most vulnerable to loss from boiling, simmering, steaming, or braising.
At what temperature do nutrients denature?
Vitamin C and heat Vitamin C begins to denature at temperatures as low as 86 °F, according to a study in the International Journal of Scientific and Technology Research. The negative effects of heat increase significantly at 140 and even more at 170 °F.
Do vegetables retain nutrients in soup?
Boiling vegetables as an accompaniment to a main meal results in some of the nutritional value being lost in the water, which is usually thrown away. Making soup with vegetables means the nutrients stay in the liquid.

Does microwave cooking destroy nutrients in food?
Microwave ovens generally do not destroy nutrients in food. For example, cooking vegetables in water increases the loss of water-soluble vitamins, and because microwave ovens can cook foods with little or no water, more nutrients are retained.
Does heat destroy vitamin b12?
Vitamin B-12 is stable at room temperature. It doesn’t need to be refrigerated. Cooking doesn’t destroy it. Vitamin B-12 does not break down even at the boiling point of water for several hours.
How can we prevent loss of nutrients in cooking?
