Editor's note: Every time you eat, you won't eat it all. So how to eat leftovers to be healthier? It is said that coarse grains are good, which way is better to eat coarse grains? Detoxification of zang-fu organs, drug supplement or food supplement? Are you confused, too Let me tell you something!

There is a way to eat leftovers.

How to eat leftovers? No meat left, no cold dishes left; Cover with plastic wrap and put it in the refrigerator for thorough cooling; Put ginger and garlic in seafood and vinegar in meat dishes; When rice is made into paste, beef becomes fluffy.

Whether you eat at home or out, it is common not to eat the rest. Some people find it convenient not to waste leftovers in the next meal; Others object that overnight dishes can't be eaten, which will cause cancer. What is more beneficial to health?

Principle: Don't leave any cold dishes.

When eating leftovers, people often worry about losing nutrition, which is harmful to health. From these two aspects, vegetarian dishes are not as reassuring as meat dishes.

As we all know, leftovers often have the problem of nitrite exceeding the standard. Nitrite itself is toxic. When it meets protein in the stomach, it will produce nitrosamines, a carcinogen. Statistics show that 80% of nitrite ingested by human body comes from vegetables. If cooked vegetarian dishes are kept in high temperature for a long time, the nitrite content will increase.

In addition, the nutrients in vegetarian dishes are more likely to be lost. This is because there are usually dozens of nutrients in a food, among which water-soluble vitamins, such as vitamins C and E, are afraid of heat. The nutritional value of vegetables is just reflected in the rich vitamins, so the nutrient loss of reheated vegetarian dishes is serious.

There are also some nutrients in food that are not too afraid of heat, such as minerals such as calcium and iron. People usually ingest these nutrients through meat dishes such as fish, so the loss of nutrients after heating will not be serious.

Therefore, no matter from the perspective of nutrition or safety, try not to eat leftovers. In addition, it should be reminded that it is best not to eat cold dish leftovers, whether it is vegetarian or vegetarian, because if it is not heated, the bacteria inside will not be easily killed, which may easily lead to diarrhea and other discomfort.

Storage: Cover with plastic wrap and put it in the refrigerator for thorough cooling.

Leftovers are not absolutely inedible, so we must pay special attention to the preservation conditions and put them in the refrigerator immediately after cooling.

It is because hot food suddenly enters a low-temperature environment, and the hot air of food will condense water vapor, promote the growth of mold, and lead to moldy food in the refrigerator. After thorough cooling, put it in the refrigerator in time, even in winter, and don't leave it outside for a long time, because the refrigerator has certain antibacterial effect.

Different leftovers must be stored separately to avoid cross contamination by bacteria. It also needs to be stored in a clean container, such as a fresh-keeping box or a fresh-keeping bag, or put a layer of fresh-keeping film on the dishes.

Don't store leftovers for too long. It's best to eat them within 5-6 hours. Generally speaking, heating at high temperature for a few minutes can kill most pathogenic bacteria. But if the food is stored for too long, it will produce nitrite and aflatoxin, and heating will not work.

Return to pot: ginger and garlic seafood, vinegar and vegetables.

Besides reasonable storage, reheating is also the key to ensure health. Leftovers are put in the refrigerator, and must be returned to the pot at high temperature before eating. Because low temperature can only inhibit bacterial reproduction, it can't completely kill bacteria.

Different leftovers have different heating skills: among leftovers, fish, shrimp, crab and shellfish are the most intolerant. Even if it is stored at low temperature, it will produce bacteria and easily deteriorate. Therefore, it is best to add some seasonings such as wine, onion, ginger and garlic when heating, which can not only refresh the mind, but also have a certain bactericidal effect to prevent gastrointestinal discomfort.

Compared with seafood and vegetables, meat is less likely to produce carcinogens such as nitrite, but it must be heated thoroughly, preferably for more than 10 minute or microwave 1 minute. When heating, you might as well add some vinegar. Meat is rich in minerals, which will overflow when heated. These substances will synthesize calcium acetate when they meet acetic acid, which is beneficial to the absorption and utilization of the human body.

Staple foods such as rice and steamed bread are best eaten the next day, because starchy foods are easy to breed staphylococci and aflatoxins. These harmful substances cannot be killed by high temperature heating. So, if you haven't finished eating for two days, don't eat any more, even if it doesn't look bad.

Renovation: rice is made into paste beef and becomes fluffy.

Eating at the last meal, eating at the next meal, has no freshness, and leftovers are often easy to stay. For the sake of health, the leftovers of the last meal must be eaten, or they must be resolutely thrown away. This needs to give full play to the imagination and make a big transformation of leftovers.

Meat salad and stir-fry will do. The simplest transformation method of beef sauce and elbow sauce is cold salad. You can slice the meat and mix it with fresh vegetables and seasonings. It can also be fried with carrots, celery and other vegetables. You can also chop the sauce meat, mix with diced green pepper and minced chives, and put it in sesame cakes to make meat buns. If there are children at home, it is not bad to chop beef sauce and stir-fry it with salt, sugar and soy sauce to make minced meat.

Fried fish often tastes old and hard when heated. In fact, you can add red pepper, diced carrot and so on, and add sugar to make a new dish.

It's much easier to steam rice at home once. In addition to fried rice and porridge, you can also break the leftovers and add tofu and eggs to make rice paste tofu soup. In addition, rice can also be mixed with potatoes and minced meat to make dry fried meatballs.

Steaming coarse grains is better than boiling.

Coarse grains are relative to flour and rice such as rice and white flour. Coarse grains mainly include two kinds: one is brown rice, whole wheat and so on; The other is miscellaneous grains except rice and wheat. For example, corn, millet, black rice, purple rice, barley, oats and buckwheat are cereals, while soybeans, mung beans, red beans and black beans are miscellaneous beans. Coarse grains can lower cholesterol and reduce the incidence of chronic diseases, such as cardiovascular disease, type II diabetes and cancer. In addition, coarse grains can also promote digestive function, relieve constipation and balance intestinal flora.

Although everyone knows that eating coarse grains is beneficial, there are still many misunderstandings when eating, especially in cooking methods, such as frying and cooking porridge, which will lose the nutrition in coarse grains to some extent. Coarse grains are rich in dietary fiber and little in fat, but if they are cooked by frying, they will absorb a lot of fat, and at the same time unsaturated fatty acids, vitamins and other nutrients in coarse grains will also be lost. Need to be reminded that coarse grains are cooked very soft and rotten. Porridge is the biggest misunderstanding. Many people think that porridge is light, healthy and easy to digest, especially its low glycemic index, and patients with chronic diseases such as diabetes should eat more. However, it is found that the softer the porridge, the higher the gelatinization degree of starch in coarse grains and the faster the blood sugar rises.

So, how to cook coarse grains to be delicious and healthy? Firstly, the cereal and beans are mixed at the ratio of 3: 1 or 2: 1 and soaked overnight. Then steam the soaked coarse grains in a steamer for 10-20 minutes. Steamed coarse grains can be mixed with rice for cooking, or you can put some medlar and walnuts and cook porridge with slow fire. However, it should be noted that this kind of porridge should be clear soup type and cannot be cooked into a sticky shape. After the coarse grains are steamed, add eggs and stir-fry them with vegetables such as tomatoes and green peppers for more balanced nutrition.

If you can't finish eating steamed coarse grains, you can divide them into small portions and eat them after freezing.

It is best to detoxify viscera and nourish food.

Liver, kidney and intestine are the main detoxification organs of human body. How do these internal organs detoxify? The experts made a brief introduction.

Liver detoxification can eat carrots.

The liver is an important detoxification organ. After a series of chemical reactions in the liver, various toxins become non-toxic or low-toxic substances. Liver detoxification, usually can eat carrots, garlic, grapes, figs and so on.

According to experts, carrot is an effective mercury-discharging food, which contains a large amount of pectin that can combine with mercury, effectively reducing the concentration of mercury ions in blood and accelerating its discharge. Eating some carrots every day can also stimulate the blood circulation of the gastrointestinal tract, improve the digestive system and remove oxygen free radicals.

Figs contain organic acids and various enzymes, which can protect liver and detoxify, clear away heat and moisten intestines, and help digestion, especially against toxic substances such as sulfur dioxide.

Kidney detoxification and eating cucumbers and cherries

Cucumber, cherry and other fruits and vegetables help the kidneys to detoxify. Cucumber can clean the urethra by diuresis, which helps the kidneys to expel toxins from the urinary system; Cherry is currently recognized as a fruit that can remove toxins and unclean body fluids for the human body. It has a very good effect on kidney detoxification and has a laxative effect.

Intestinal detoxification and eating konjac honey

Intestines can excrete toxins quickly, but if it is indigestion, it will cause toxins to stay in the intestines and be reabsorbed, which will do great harm to health.

Amorphophallus konjac, honey, auricularia auricula, kelp, pig blood, apples, strawberries, brown rice and other foods can help the digestive system detoxify. Konjac, also known as "Ghost Taro" and "Snake Valley" in Chinese medicine, is a famous "gastrointestinal scavenger" and "blood purifier", which can remove the waste on the intestinal wall; Honey has been a good product for detoxification and beauty since ancient times, and it contains a variety of amino acids and vitamins needed by the human body.
