Microwave Oven, its Benefits and Dangers.

 

 

A microwave oven (commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiations  in the wave frequency range. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric energy . Microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the outer 25–38 mm (1–1.5 inches) of a homogeneous high water content food item.

Benefits of Microwave oven

1. Reheating food

The number one use of a microwave oven by far is to reheat food. A microwave oven is very efficient at reheating food, retains essential nutrients and doesn’t make food soggy. In fact, microwaves work great in reheating just about any kind of food.

2. Cooking

While most people usually consider their cooktops and stoves for cooking, you can actually cook a lot of foods in your microwave ovens. Multifunctional microwave oven in perth, such as those we offer at Ross’s Discount Home Centre, can be used for baking, grilling, roasting, blanching, boiling and steaming food items. The versatility of a microwave oven allows you to do all this without needing separate kitchen appliances.

3. Disinfect kitchen items

Microwave ovens can help to disinfect kitchen items such as plastic cutting boards and sponges. Just soak your sponges and cutting boards in some lemon juice and heat them in a microwave for a minute. This will both disinfect as well as deodorize your kitchen items.

4. Making citrus fruits juicier

Another great thing you can do with a microwave oven is to make citrus fruits juicier. So, the next time you take a lemon or orange out of your refrigerator, don’t juice it immediately. Microwave the fruit for just 20 seconds, and you’ll be able to squeeze out a lot more juice!

5. Heating beauty products

Certain beauty products feel much better on the skin simply if they are heated up before application. While warming up beauty products can be inconvenient otherwise, a microwave oven makes things much simpler and less messy. You can use a microwave to heat up facial masks, hot oil conditioning packs and reheat gel packs easily.

Dangers of Microwave Oven

1️⃣Microwaves Zap Food Nutrition

Heating your food in the microwave can strip away its original nutrients. What may have started as a nutritious plate of food has now evolved into “dead food” due to the dielectric heating of microwaves. “They bounce around the inside of your [microwave] oven and are absorbed by the food you put in it,” writes Dr. Joseph M. Mercola, licensed physician and surgeon. The water molecules rotate rapidly in the microwave and in the food in high frequencies which creates molecular friction and heats up your food. This causes the molecular structure in your food to change, and as a result diminishes the nutrient content in the food.

2️⃣Microwaves Destroy Breast Milk And Vitamin B-12
The health benefits of vitamin B-12 are instantly negated once heated in a microwave. In a study published in the Journal of Agricultural and Food Chemistry, researchers decided to examine the effects of microwave heating on the loss of vitamin B-12 in foods like raw beef, pork, and milk. The results of the study show there was a 30 to 40 percent loss of the vitamin when the foods received microwave exposure. The shift of vitamin B-12 to an inactive form of the vitamin was found in foods during the microwave heating process.

The powerful bacteria-fighting agents in breast milk are also destroyed by microwave heating. Findings published in the journal Pediatrics examined the common practice of using a microwave to heat frozen human milk for convenience in intensive care nurseries. Researchers tested 22 freshly frozen human milk samples to test them for lysozyme activity and antibodies by heating the samples for 30 seconds on either a low or high power setting. Breast milk microwaved at high temperatures was found to have greater E coli growth — 18 more times than the control (unmicrowaved) breast milk. Microwaving at low temperatures also dramatically decreased lysozyme activity and also promoted the growth of harmful bacteria for babies.

3️⃣Microwaves Can Change the Makeup of Your Blood
In a Swiss clinical study, researchers found that blood changes in individuals who consumed microwaved milk and vegetables. The eight participants in the study ate a series of food prepared in different ways, including food heated in the microwave. The results of the study showed red blood cells decreased while white cell levels increased, along with cholesterol levels. The non-ionizing radiation of the microwave can affect changes in your blood and your heart rate.

4️⃣Microwaves Can Change Your Heart Rate
Microwaves can produce effects on your body instantly due to the 2.4 GHz radiation — the frequency of radiation emitted by microwave ovens. A study conducted by Dr. Magda Havas of Trent University found the levels of radiation emitted by a microwave affect both heart rate and heart rate variability. These levels are within federal safety guidelines but tend to cause immediate and dramatic changes in heart rate. If you experience irregular heart beat or any chest pain and regularly eat microwaved food, it might be best to discontinue use.

5️⃣Microwaves Create Carcinogens In Food.

Carcinogens are agents that cause cancer.
When you heat foods that are wrapped in plastic in the microwave, you can create carcinogens in the food. Based on Russian research and German studies, the Russian government issued a warning about the health hazards microwave ovens can have on the human body and the environment. The assembling of microwavable foods are found to contain toxic chemicals such as BPA, polyethylene terpthalate (PET), benzene, toluene, and xylene. The plastic containers used to heat these microwave meals have been found to release the carcinogens along with other harmful toxins into your food which is then absorbed by your body.

Conclusion.

A microwave oven is a very versatile kitchen appliance which offers a whole range of uses. Microwave ovens can be used to reheat and cook food, disinfect kitchen items, make citrus fruits juicier, heating beauty products, roasting garlic and de-crystallising honey.
