Is microwaving food safe?
You may have heard that microwaving food can be harmful for you, but at the same time you've got leftovers in the fridge waiting to be reheated. This article will give you a clearer picture regarding microwaving food and debunk some myths surrounding it.
Does microwaving food kill its nutrients?
Some nutrients, such as vitamin C, are broken down when exposed to heat, regardless of heat from a microwave or stovetop. However, the short cooking time from microwaves actually preserves the nutrients better than the prolonged heat exposure from other cooking methods. In addition, microwaving does not require a large body of fluid, which helps to minimise loss of water-soluble vitamins in the fluid.
Toxicity of microwaving?
Using the right type of cooking ware or container is very important. Ensure that the medium used is microwave-safe to prevent hazards from occurring. Avoid anything with metal, aluminium, plastic wraps, plastic bags and containers that are not microwave safe, and microwavable takeout dinner trays which are formulated for single use only. Worn out containers, or those that have been microwaved many times, may be at risk of leaching out more plasticisers.
Therefore, microwaving food is time efficient, safe and helps retains nutrients more than other cooking methods. Just be sure you are using the right type of kitchenware and vent the container by leaving a small opening when cooking in the microwave.
