5 Things You Should Never Microwave But You Didn’t Know

5 Things You Should Never Microwave But You Didn’t Know

You might want to think twice before going to heat up that plastic covered stew from last night.

Along with a fridge, stove and TV, I am pretty willing to bet you have a microwave in your home. That is a pretty safe bet as 95% of Americans own a microwave oven.

An Accidental Invention

Many things around us today have come about as a pure fluke such as post it notes, the Slinky, and Kim Kardashian’s career.

The Microwave falls under this category as well.

Percy L. Spencer was an electronics genius who served during World War II. On a tour, one of his laboratories he stopped for a moment in front of a magnetron, not the villain from Transformers but a large tube that drives radars. The tube’s ability to heat was noticed from a melting chocolate bar that was in his pocket.

To see if it was genuine heat, Spencer tested a bag of popcorn kernels that ended up popping all over over the room.

Seeing an Opportunity

This phenomenon might have just been regarded as an amusing experiment to Percy, similar to people dropping Mentos into bottles of Diet Coke; however he had over 150 patents to his name and saw a possibility.

The first microwave oven stood five foot six inches tall and weight 750 pounds.

The microwave found a place early on in restaurants, rail cars and ocean liners as a means to cook large quantities of food.

It would take decades though before the microwave oven was developed as beneficial and affordable for the average family.

Cooking With a Radar Box

Make no mistake, a radar box is exactly what a microwave oven is. A microwave cooks food with oscillating electromagnetic energy that are very similar to radio waves but move back and forth at a much greater speed.

Where a normal oven’s heat slowly penetrates through food, microwave oven heat immediately reaches molecules around an inch below the surface of the food.

Microwaves produce non-ionizing radiation and there are studies that show that this can affect changes in your blood and heart rate along with microwaved food causing certain type of intestinal and stomach cancers

What specific things can be compromised by using a microwave?

Microwave ovens have to go through much more extensive testing and safety procedures these days so manufacturers will say the health risks are greatly reduced. Convenience is paramount and people will understandably try to save time when possible, but here are 5 things you are better off never putting in a microwave oven.

1. Breast Milk

A key benefit of providing a newborn breast milk is being able to introduce the baby to powerful bacteria-fighting agents that are contained within the milk.

The Journal of Pediatrics ran tests on 22 samples of frozen breast milk heated in a microwave on either low or high heat and found that breast milk heated on high heat showed greater E-coli growth. This was 18 times higher than the milk heated without a microwave.

The samples microwaved at lower temperatures dramatically decreased isozyme activity as well as promoted the growth of harmful bacteria for babies

2. Broccoli

Broccoli is no stranger to the microwave as it is one of the most common quick heated vegetables around.

Any form of cooking is going to destroy some nutrients in food. Steaming is the most gentle and still causes a loss of around 11% of the antioxidant content of broccoli.

Cooking broccoli in a microwave with a bit of water lost up to 97% of its beneficial antioxidants.

3. Frozen Fruit

This has always been a big time saver. Buying frozen foods is actually not a bad idea as the flash freezing process can help preserve the nutrients of the fruit. Fruit immediately starts losing nutrients the moment it is picked. This is why frozen fruit or veg from the other side of the country can have a higher nutrient profile than local organic produce that might have spent more than a week in storage, transit and then on shelves.

Russian studies in the late 70’s revealed that defrosting frozen fruit in a microwave ended up converting beneficial glucoside and galactaside into carcinogenic substances.

The Russians also continued studies into the early 90s that showed immunological effects of microwaves.

Frozen fruit is best thawed in a fridge or simply on a counter top at room temperature.

4. Defrosted Meat

Some microwaves rotate and some do not, which can lead to uneven distributions of cooking and thawing.

Frozen meat is a tough thing to have to defrost in a microwave, as it can take so long that it becomes very easy to start cooking it. Edges of meats can start to cook and turn brown while the inside remains frozen.

When that meat gets to the 40-140 degrees fahrenheit level bacteria begins to grow and multiply. If the meat is not immediately cooked you are looking at a pretty contaminated piece of meat.

Japanese researches found that meats cooked longer than 6 minutes in a microwave also lost half of its vitamin B-12 content.

The best thawing tips are to let it defrost in a fridge overnight or thaw under cold, running water.

5. Dishes Covered in Plastic Wrap or in Plastic Containers

There are a lot of takeaways from this, but a very key one is to not microwave anything with any form of plastic around it. When you heat foods covered in plastic you can create carcinogens.

Heating these plastic wraps or containers can release harmful toxic chemicals directly into your foods. Some of the chemicals that can be derived from plastics are:

  • BPA
  • polyethylene terpthalate (PET)
  • benzene
  • toluene
  • xylene

Related to the breast milk issue above, it seems smart to not heat up any form of plastic baby bottle in a microwave.

Wrapping It All Up

Big changes in safety and design have definitely taken place in the manufacturing of microwave ovens. The companies that sell these products will be quick to point out the safety measures that were taken in their product’s creation.

Of course these companies will say that though, they really do not have a choice when sales and revenue are the bottom line.

The point is to try and prepare foods as traditionally as possible and eliminate or at least drastically reduce the use of microwave cooking.

Our time saving measures can actually end up causing us more problems in the long run.

How to Tap Into the Power of Positivity

How to Tap Into the Power of Positivity

As it appears, the human mind is not capable of not thinking, at least on the subconscious level. Our mind is always occupied by thoughts, whether we want to or not, and they influence our every action.

“Happiness cannot come from without, it comes from within.” – Helen Keller

When we are still children, our thoughts seem to be purely positive. Have you ever been around a 4-year old who doesn’t like a painting he or she drew? I haven’t. Instead, I see glee, exciting and pride in children’s eyes. But as the years go by, we clutter our mind with doubts, fears and self-deprecating thoughts.

Just imagine then how much we limit ourselves in every aspect of our lives if we give negative thoughts too much power! We’ll never go after that job we’ve always wanted because our nay-saying thoughts make us doubt our abilities. We’ll never ask that person we like out on a date because we always think we’re not good enough.

We’ll never risk quitting our job in order to pursue the life and the work of our dreams because we can’t get over our mental barrier that insists we’re too weak, too unimportant and too dumb. We’ll never lose those pounds that risk our health because we believe we’re not capable of pushing our limits. We’ll never be able to fully see our inner potential because we simply don’t dare to question the voices in our head.

But enough is enough! It’s time to stop these limiting beliefs and come to a place of sanity, love and excitement about life, work and ourselves.

So…how exactly are we to achieve that?

It’s not as hard as it may seem; you just have to practice, practice, practice. Here are a few ideas on how you can get started.

1. Learn to substitute every negative thought with a positive one.

Every time a negative thought crawls into your mind, replace it with a positive thought. It’s just like someone writes a phrase you don’t like on a blackboard and then you get up, erase it and write something much more to your liking.

2. See the positive side of every situation, even when you are surrounded by pure negativity.

This one is a bit harder to put into practice, which does not mean it’s impossible.

You can find positivity in everything by mentally holding on to something positive, whether this be family, friends, your faith, nature, someone’s sparkling eyes or whatever other glimmer of beauty. If you seek it, you will find it.

3. At least once a day, take a moment and think of 5 things you are grateful for.

This will lighten your mood and give you some perspective of what is really important in life and how many blessings surround you already.

4. Change the mental images you allow to enter your mind.

How you see yourself and your surroundings make a huge difference to your thinking. It is like watching a DVD that saddens and frustrates you, completely pulling you down. Eject that old DVD, throw it away and insert a new, better, more hopeful one instead.

So, instead of dwelling on dark, negative thoughts, consciously build and focus on positive, light and colorful images, thoughts and situations in your mind a few times a day.

If you are persistent and keep on working on yourself, your mind will automatically reject its negative thoughts and welcome the positive ones.

And remember: You are (or will become) what you think you are. This is reason enough to be proactive about whatever is going on in your head.
