Thanksgiving is a time of feasting and indulgence, but what happens when the leftovers start piling up? While leftovers are often a hit, one expert has revealed some foods that should never be reheated due to the health risks they pose. In this article, we'll explore which foods to avoid reheating and why.

Protect Your Health with Proper Reheating Choices

Spinach: A Food to Avoid Reheating

Spinach, according to dietitian Harini Bala, contains nitrates. Studies have shown that the levels of nitrates increase with cooking. When reheated at high heat, such as when warming up the leafy greens, these nitrates are converted to nitrosamines, a compound linked to cancer. Bala urged in a TikTok video with over 149,000 views to not reheat spinach but to eat it immediately after cooking. She emphasized that the compounds in reheated spinach are "toxic."

Imagine the disappointment of taking a bite of reheated spinach, only to realize the potential health risks. It's important to listen to the experts and avoid this common mistake. By not reheating spinach, you can protect yourself from the harmful effects of nitrosamines and enjoy this nutritious vegetable in its freshest form.

Tea: Another Food to Be Cautious With

When reheated, the antioxidant properties of tea break down, while the level of tannins, which contributes to the bitter taste, increases. Bala also claimed that any "dormant bacteria" in the tea will become "active" with reheating, posing a health risk to consumers. Microwaving tea can affect its taste and potentially introduce harmful bacteria into your body.

Think about the last time you reheated tea. Maybe it didn't taste quite the same, or you noticed a strange aftertaste. This is because of the changes that occur during reheating. By being cautious about reheating tea, you can ensure that you're enjoying a safe and delicious beverage. Avoid the risks and savor your tea in its original form.

Rice: The Sticky Situation

The starch in rice is fine to be reheated as long as it is stored in an airtight container inside the fridge within two hours of cooking. However, waiting longer than two hours to put it away increases the risk of dangerous bacteria proliferating in the food. Bala warned that if you cook rice in the morning and store it in the fridge at night to eat the next day, there is a huge possibility of Bacillus cereus forming.

Bacillus cereus is a type of bacteria that usually affects starchy foods and can result in food poisoning, often referred to as "fried rice syndrome." This serious illness has even led to death in rare instances. By following proper storage and reheating guidelines for rice, you can minimize the risk of food poisoning and keep yourself and your family safe.
