10 Foods You Should Never Eat As Leftovers

Foods You Should Never Eat As Leftovers

Spinach

If you’ve made too much spinach only for a quick and nutritious side dish, it’s best if you just toss it out or eat the leftovers cold. As an alternative, you can also stir it into a pasta salad.

The thing with spinach is that it contains a high quantity of nitrates, which our bodies need in order to function properly. When we eat some of these vegetables raw, our bodies turn these good-for-you nitrates into nitrites.

So, nitrates don’t represent a problem for us until the heating process activates them. They can release poisonous carcinogenic effects when they’re being processed, so it’s best to avoid reheating altogether.
