Leftover foods may have been a respite in the course of sudden hunger pangs during odd hours of the day. All you need to do is to reheat and savour them without having to waste any extra minute in cooking. But wait, have you ever wondered if the foods that you are reheating are safe to eat anymore? Well, some every day foods that we consume may not be as safe after being reheated as they tend to lose their nutritional value. Yes, you heard us. According to Nutritionist Lokendra Tomar from Weight Loss Clinic, Delhi, "Here's a golden rule of reheating food - never ever reheat high-protein foods."
Read on as we list down foods suggested by Lokendra Tomar that you must stop reheating right now. Take a look -
1. Vegetables with High Amounts of Nitrates
If you have spinach or any green leafy vegetables, carrot, turnip or even celery, avoid reheating them in the microwave. These nitrate rich vegetables when heated again can turn toxic, releasing carcinogenic properties, which are generally cancerous in nature. Spinach contains high amount of iron, hence heating and reheating spinach may oxidize the iron present in spinach. Oxidation of iron generates dangerous free radicals which are known to cause many diseases including infertility and cancer.

You may be surprised, but rice comes under this category too. According to Foods Standards Agency (FSA), you could suffer from food poisoning by eating reheated rice. This is due to the presence of highly resistant bacteria called Bacillus Cereus. Heat kills these bacteria, but it can produce spores that are toxic in nature. Once rice is reheated and is left out at room temperature, any spores it contains can multiply, further causing food poisoning on consumption.

Potatoes being a staple are the best and easiest to store, reheat and consume. Unfortunately, you would need to think again. Potatoes are a rich source of vitamin B6, potassium and vitamin C, however, if they are reheated again and again, chances are they might produce Clostridium Botulinum (bacteria causing Botulism). Even if you leave the cooked potatoes out in room temperature, the production of bacteria will only increase. So if you want to avoid the growth of bacteria, best is to keep them refrigerated or throw them away if not being consumed within 1-2 days.
6. Mushroom Potatoes are a rich source of vitamin B6, potassium and vitamin C
It is recommended to eat mushrooms as soon they are prepared. Ideally, they shouldn't be stored to consume next day as it is a powerhouse of proteins and have generous amounts of minerals and by reheating them, you are breaking these proteins further, causing havoc in your digestive system. Hence heating them will generate toxins which contains oxidized nitrogen and free radicals. Even if you are keen on storing mushrooms for the next day, make sure you eat them cold.
