Leafy greens such as spinach and kale contain high levels of nitrate, which can be converted to carcinogenic nitrosamines when heated.

In layman’s terms, your greens might turn toxic and can poison you! Quite the opposite effect of your attempt to eat clean.

Chicken and turkey can contain salmonella. In the microwave, the meat can be heated unevenly, so some parts of the protein breaks down quicker than others, which can lead to a stomach upset.

If you choose to reheat your poultry, make sure it’s cut up into smaller chunks so it’s heated more evenly through and through, and rotate it frequently to ensure even cooking. Make sure the inside of the meat is piping hot before consuming.

If not stored properly or left out in room temperature, rice is an excellent breeding ground for all sorts of bacteria and food-borne viruses, which reheating in the microwave won’t get rid of.

The same goes with potatoes – bin them if you’re not going to finish them!

Protein-rich foods like mushroom and eggs should be consumed soon after preparation. Otherwise, the proteins deteriorate in a matter of a day or two and cause a tummy upset when consumed.

If you don’t want to throw out your mushrooms, try incorporating them into a salad and eating them cold the next day.
