Broccoli

Even though not adored by kids, broccoli provides extra flavor and nutrients that many food lovers crave. Heating up this veggie in the microwave is quite simple. But if you microwave broccoli, 97% of its nutritional value is lost, so it's a waste.

Additionally, heating broccoli normally already destroys many of its beneficial properties. When broccoli is microwaved, 11% of its antioxidants are entirely removed when compared to broccoli is steam-cooked. If you still want to reheat it, when reheating, you need to be mindful of the temperature, or you will ruin its texture and make it mushy. And keep in mind that reheating broccoli twice will affect its taste and freshness, and it may turn mushy or even cause food poisoning. It is advised that vegetables, especially roasted ones, should not be reheated twice.
