Is It Safe to Reheat Spinach?

The question of whether you can reheat spinach is several decades old. Today, if stored properly, it is unfounded. You should only be careful with children and babies. Adults can usually consume spinach without any problems, even if it has been stored.

Why you can reheat spinach

You can reheat spinach. However, not more than once and with more than 70 degrees Celsius.

• Spinach contains nitrates. They are neither healthy nor unhealthy. Nitrates have an important function in the body. They lower blood pressure and are important for healthy digestion. However, bacteria form nitrite from the nitrate at room temperature. Nitrite is not entirely healthy.
• In small amounts, nitrites in the human body lower blood pressure. In large quantities and when consumed in excess, the substance is carcinogenic. The amounts that an adult consumes with spinach are not harmful to health. All you need to know is how to properly handle the spinach.
• If possible, keep the spinach in the refrigerator. This slows down the process by which the bacteria convert the nitrate in the spinach to nitrite. However, if possible, the spinach should be prepared and not spend more than a day in the refrigerator. When you reheat the spinach, it should be at least 70 degrees Celsius to kill bacteria.

Reheat spinach – so you won’t do anything wrong

If you reheat spinach, you should only bring it to a temperature of 70 degrees for a short time, otherwise many healthy nutrients will be lost.

• Do not reheat the spinach more than once. If you cook the spinach and reheat it a second time later, you can do that with no problems. However, you should not chill the spinach a second time or put it in the fridge and reheat it a third time.
• If you have babies or children in your household, be careful with spinach, radishes, kohlrabi and beetroot. Children have weaker immune systems than adults. Too much nitrate can quickly lead to cyanosis, which is a consequence of nitrate poisoning.
• If you want to do as much as possible right, it is best not to buy fresh spinach but to use the frozen version. The spinach that you get frozen in the supermarket is in most cases harvested at the right time and frozen immediately. This keeps the nitrate content at a minimum.
• Reheating spinach is not dangerous as long as you do everything right. Nowadays, however, it’s easier than ever to consume spinach in the healthiest way possible. There are also people who are very sensitive to spinach. In this case, you should avoid the vegetables when they are warm and consume them immediately after preparation.
