Crit Rev Food Sci Nutr. The effect of microwaves on nutrient value of foods. Microwave cooking has gained considerable importance as an energy-saving, convenient, and time-saving cooking method.
Or that it may destroy the micronutrients in your food? Or even cause cancer? Are we worrying about nothing? Or is there some truth to these? By the end of this article, we will have addressed each of these concerns.
Do microwaves destroy beneficial nutrients? Researchers have since been investigating how microwaving foods may influence their nutrient content, in a good way OR a bad way. In a study published in The Journal of Agricultural and Food Chemistry, it was found that broccoli retained all of its minerals when microwaved but lost vitamin C, which leached into the added water.
Does this mean that we should avoid microwaving our vegetables? Firstly, vitamin C is quite volatile in heat, so cooking in general causes its loss.
Luckily, C is plentiful in raw fruits and vegetables, so you can compensate there. What about omega 3 in fish? A study published in Food and Bioproducts Processing investigated the effects of different cooking methods on the nutrient content of seabass.
Losses of omega 3 fats were higher in the microwaved seabass than in the fried seabass. Click HERE to learn more about this. Are microwave containers risky?
When food is wrapped in plastic or placed in a plastic container and microwaved, chemicals from the plastic can leak into the food.
This seems to be causing a lot of worry for people but, according to the Harvard Medical School, this is closely regulated: On the other hand, the organisation Breast Cancer UK urges the authorities to ban BPAa type of plastic not only used in microwave ovenware but also in most packaged products!
Does microwave radiation make foods radioactive?
But is this true? Have you ever thought about what radiation actually is? Radiation can be found all around us, in varying amounts. It is essentially the release of energy, which is given off by everyday things, such as the sun and household electrical appliances.
We are always being exposed to natural background radiation. From radioactive gases given off from the earth, to radioactive substances in the soil.
Have you ever had an x-ray? Ever used a sunbed? Your mobile phone gives off radiation, as do computers, heaters, and radios.
So does this mean that we are in constant danger from microwaves and the world around us? Firstly, it is important to understand how a microwave works. How do microwaves work? Ionising radiation, which can remove tightly-bound electrons from atoms, causing them to become charged, is less risky in very tiny amounts such as x-rays but can cause problems when exposure is high think burns and even DNA damage.
However, microwaves emit non-ionising radiation; a type of radiation that has enough energy to move atoms around within a molecule but not enough to remove electrons. What does this mean? Because the radiation from microwaves is non-ionising, it can only cause molecules in the food to move.
In other words, microwave radiation cannot alter the chemical structure of food components.The Effects of Microwaving on Food. by KIRSTIN HENDRICKSON Aug.

rather than effects unique to . Heating food, in and of itself, can result in some nutrient loss, but using microwaves to heat food introduces the additional problem of the "microwave effect," a phenomenon that will be discussed in detail later. In other words, microwave radiation cannot alter the chemical structure of food components.
More precisely, when heating food in a microwave, the radiation that the microwave produces is actually absorbed by the water molecules in the food.
Although generally recognised as safe, the internet is awash with articles about the dangers microwave radiation poses to your food.
Some claim using microwaves can cause “ cataracts and cancer ”. Feb 09, · The negative effects of microwave oven food is all over the internet.
Over the years, many studies have been carried out on the dangers of microwave oven foods on the health, and the findings are indeed alarming. Microwave cooking has gained considerable importance as an energy-saving, convenient, and time-saving cooking method.
This article reviews the state of the art of microwave cooking and the existing publishing data on the effects of microwave cooking on nutritive values of moisture, protein, carbohydrate, lipid, minerals, and vitamins.
