1. Dishes with leafy greens
Many people have the habit of preparing dishes with a lot of leafy greens and then reusing leftovers the next day. This is one of the harmful habits that you need to stop immediately. Nutritionists have pointed out that the nitrate in leafy greens, when cooked and left overnight, can turn into nitrite, a carcinogenic agent.

It's best to consume leafy greens as soon as possible. If you plan to cook in advance and store for the next day, opt for cooking root vegetables as they produce less nitrite. Typically, nitrite levels ranging from 0.2 to 0.5 grams can lead to food poisoning with an incubation period of 1 to 2 days.
2. Dishes prepared with eggs
Eggs are a nutrient-rich food, but if not stored properly, they can pose health risks. Nutritionists also caution that the shelf life of boiled or fried eggs is quite short.

Discard leftover eggs after a meal and avoid using them the next morning. Allowing eggs to sit overnight creates favorable conditions for rapid bacteria growth. At temperatures below 100C, processed eggs can undergo transformation leading to intestinal diseases.
3. Seafood dishes
When you've fully cooked seafood, especially shrimp, crab, fish, and leave it overnight, the substances in seafood will negatively affect the user's liver and kidneys. The salt content in seafood will be higher compared to other foods. If left overnight, this salt content will convert to nitrite, causing extremely serious cancer risks.

In case you've purchased a large quantity of seafood, cook only what you'll consume for the meal, and store the rest in the refrigerator's freezer compartment for the next day's use.
4. Mushrooms, fungus
Due to the moist environment in which mushrooms and fungus thrive, cautious handling is crucial during preparation. Leaving processed mushrooms and fungus overnight can lead to nutrient depletion, causing discomfort for the stomach.

Processed mushrooms and fungus contain beneficial nitrates for blood cells. However, leaving them overnight will transform nitrates into nitrites, severely impacting your health.
5. Braised dishes
Braised dishes are a staple in many households, serving as a rice-saving option. However, soft braised dishes can quickly spoil if not stored correctly.

Reheating old food cannot eliminate all bacteria in braised dishes. Even when stored in the fridge, it may not entirely guard against harmful factors, so exercise caution when preparing this dish.
6. Dishes made from soybeans
The shelf life of soybeans, once processed, is quite short. Consume them promptly before bacteria proliferate. It's advisable to eat soybeans only after cooking for 2 hours to ensure absorption of the nutrients, avoiding health risks. Avoid reheating multiple times, as harmful substances may develop in soybeans.

7. Potato-based Dishes
Potatoes are a food that provides nutritional protein and beneficial fiber for the body. However, reheating potatoes multiple times can make them odorous and deplete their nutrients.

Therefore, it's advisable to finish potato-based dishes and avoid storing them for the next day. Doing so may create conditions for bacterial invasion, leading to nutrient alteration, potential poisoning, and digestive issues for consumers.
