Next couple posts – and many more in the future – will show how to warm easy to make pasta meals in the microwave oven. Before actually showing how to make any of those meals, I first want to address a concern some people have about microwave oven cooking safety prompted by a recent comment left on my “How to Make Microwave Cooked Broccoli” video stating that microwave cooking changes vegetable cell structure and therefore makes those microwave cooked vegetables potentially cancerous.

I’ve heard that comment before. I’m sure you have, too. It is not true. Microwave cooking does not change cell structure other than potentially bursting their cell walls as steam builds inside the cells when they are heated the same way vegetable cells can burst through stove top or oven cooking.

Here is a description explaining how microwave ovens cook food that I paraphrased from the US Department of Agriculture (USDA), Food and Drug Administration (FDA) and World Health Organization (WHO) resources listed at the end of this article: An electronic tube, called a magnetron, inside a microwave oven converts ordinary wall socket electric power into 2450 Megahertz microwaves (electromagnetic waves that are about 5 inches long) that cause molecules in water, fats and sugars in food to vibrate very quickly. That fast vibration and friction, like rapidly rubbing your hands together, causes heat which then cooks the food.

Here’s what the magnetron looks like in my microwave oven.

In order the ensure safe cooking, as detailed in your microwave oven owner’s manual,…

…make sure there are no cracks inside the microwave walls or door seal. Use only microwave safe containers or dishes when cooking food in a microwave oven and don’t cover foods with plastic wrap to prevent splatter because some of the plastic can melt and get into your food. As shown below, I use a wetted paper towel to prevent splatter, which works great!
