1. You can eat bananas, eggs (not suitable for eating raw) and roasted sweet potatoes together. The three foods are not mutually exclusive.

2. Expand knowledge

1. Banana, a plant of the genus Musa in the Musaceae family, also refers to its fruit. It is widely cultivated and eaten in tropical areas. Bananas are fragrant and nutritious, can be harvested year-round, and are valued in temperate regions. The plant is a large herb, emitting from the rhizome, and forming a false stem 3 to 6 meters (10 to 20 feet) high from the lower part of the leaf sheath; the leaves are oblong to oval, and some are 3 to 3.5 meters (10 feet) long. ~11.5 feet), 65 cm (26 inches) wide, with 10 to 20 clustered stem tops. The spikes are large, pulled out from the top of the false stem, with many flowers, light yellow; the inflorescences are drooping, with 10 to 20 bunches of fruits, about 50 to 150 in number. The plant dies after bearing fruit, and the suckers grown from the rhizome continue to reproduce. Each plant can live for many years. Originating in southeastern Asia: It is cultivated in Taiwan, Hainan, Guangdong, Guangxi and other regions.

Pharmacological effects: Fruit pulp contains a lot of norepinephrine, 5-hydroxytryptamine and dihydroxyphenylethylamine. Fruits produced in Japan contain 5-hydroxytryptamine at 10-15 micrograms/g. According to measurements, those produced in Uganda The norepinephrine content in bananas produced is 2 micrograms/g, and the 5-hydroxytryptamine content is 16.2 micrograms/g.

Daily ingestion of 10 mg of serotonin will not impair gastrointestinal function, but ingesting too much may cause gastrointestinal dysfunction.

Bananas should not be eaten when urinary indole or catecholamine levels are measured.

Immature banana meat can prevent (take at the same time) or treat (take banana meat 15 days after taking phenylbutazone) phenylbutazone-induced gastric ulcer in guinea pigs; It also had a protective effect on gastric ulcers induced by exercise in rats, but not on those induced by prednisone.

This protective effect may be due to the fact that the 5-hydroxytryptamine contained in it reduces gastric acid and the banana meat relieves irritation. It has no anticholinergic effect or central inhibitory effect.

Suitable people

Banana prolongs life and is suitable for all ages. It is the first choice for those who want to lose weight. It is suitable for people with fever, dry mouth and polydipsia, laryngeal cancer, dry and difficult stools, hemorrhoids, anal fissures, bloody stools, cancer patients and those after radiotherapy and chemotherapy; suitable for people with upper gastrointestinal ulcers, tuberculosis, and stubborn dry coughs; People who drink too much and have unresolved alcoholism should eat it; it is suitable for people with high blood pressure, coronary heart disease, and arteriosclerosis; it is suitable for people with steatorrhea and toxic indigestion.

People who are unwell

The first one is those whose constitution is weak and cold

It is better to avoid bananas if they are cold in nature and have weak constitution, such as those with cold stomach and weak constitution. Do not eat bananas if you are suffering from cold, nephritis, etc. If these patients eat bananas, it will not be good for your health. For patients with swollen feet during pregnancy, it is best not to eat bananas.

The second fasting person

Banana can promote gastrointestinal peristalsis. If eaten on an empty stomach, it will cause the gastrointestinal tract to work in advance. Eating bananas on an empty stomach for a long time is not good for the health of the body. . Why can't you eat bananas on an empty stomach? Because there is almost no food for digestion in the stomach on an empty stomach. Eating bananas on an empty stomach will speed up gastrointestinal movement, promote blood circulation, increase the load on the heart, and easily lead to myocardial infarction.

Third, patients with arthritis and diabetes

The sugar content of bananas is relatively high, which will slow down blood circulation and accumulate metabolites. If patients with arthritis and diabetes do not Bananas should be eaten, otherwise the condition will be aggravated.

Patients with fourth nephritis

Patients with nephritis cannot eat bananas, because bananas contain a large amount of potassium and magnesium. Patients with nephritis have poor filtration function, and bananas will cause The imbalance of calcium, potassium and magnesium in the blood can promote the aggravation of kidney disease, so people with cold kidney disease should avoid eating bananas.

2. Eggs, also known as chicken eggs and chicken eggs, are eggs produced by hens. They have a hard shell on the outside and an air chamber, egg white and yolk inside. Rich in cholesterol and nutrients, an egg weighs about 50 grams and contains 7 grams of protein.

The amino acid ratio of egg protein is very suitable for the physiological needs of the human body and is easily absorbed by the body. The utilization rate is as high as over 98. It has high nutritional value and is one of the foods commonly consumed by humans.

Applicable people

Suitable for most people. It is an ideal food for infants, pregnant women, parturient women and patients. For most people, no more than 2 per day is enough. From a nutritional point of view, in order to ensure a balanced diet and meet the needs of the body without causing excessive nutrition, it is generally appropriate for the elderly to eat 1 to 2 eggs a day. Young and middle-aged people, those engaged in mental work or light physical work, can eat 2 eggs a day; those engaged in heavy physical work, which consumes more nutrients, can eat 2 to 3 eggs a day; teenagers and children, due to their long bodies and fast metabolism, can eat 2 eggs a day. You should also eat 2 to 3 eggs. Pregnant women, parturient women, wet nurses, weak people, and patients recovering from major surgery need to increase their intake of high-quality protein. They can eat 3 to 4 eggs a day, but not more.

Not suitable for people

People suffering from hepatitis, high fever, diarrhea, cholelithiasis, skin sores and suppuration and other diseases should not eat eggs; the elderly, especially those with blood lipid disorders and hepatitis patients It is best not to eat egg yolks, but to eat more egg whites. In patients with nephritis, kidney function and metabolism are reduced, and when urine output is reduced, all metabolites in the body cannot be excreted by the kidneys. If too many eggs are eaten, urea in the body will increase, which may aggravate the condition. , or even uremia. Therefore, any kidney disease patient should avoid eating eggs when experiencing renal failure.

Eggs should not be eaten together with soft-shelled turtles. At the same time, raw eggs should not be eaten. This is mainly because eating raw eggs regularly will inhibit the body's absorption of biotin. A lack of this nutrient may lead to skin eczema, fatigue, poor appetite, baldness and other problems; the high cholesterol content of eggs also It is not advisable to eat too much. It is better for teenagers to take 2 pills a day and for the elderly to take 1 pill a day.

Notes

Eggs must be cooked and not eaten raw. When beating eggs, beware of bacteria contaminating the eggshells. Infants, young children, the elderly, and patients should boil, lie down, steam, or throw eggs when eating them. Don’t eat hairy or rotten eggs. People with coronary heart disease should not eat too many eggs. Children should eat no more than 2 eggs a day, and elderly people should eat no more than 3 eggs. People with existing hypercholesterolemia, especially severe patients, should eat as little or as little as possible, or You can eat egg whites instead of egg yolks, because the cholesterol content in egg yolks is three times higher than that in egg whites, up to 1,400 mg per 100 grams.

Do not eat it with soy milk

Soy milk contains a special substance called trypsin, which reacts with the egg pine protein in the egg white, causing the loss of nutrients and reducing the nutritional value of both. So don’t drink soy milk while eating eggs.

Do not eat with sugar

Because eggs are rich in protein, the main component of protein is amino acids, and amino acids will react with sugar to form fructosyl lysine. This substance is not easily absorbed by the human body and is harmful to health, especially for people with poor gastrointestinal function.

People with kidney disease should eat eggs with caution.

Eggs are a food that people often eat. Many people know that they have high nutritional value, but they ignore the dietary taboos of eating eggs. In daily diet, eating eggs, sugar and rabbit meat together are some of the biggest misunderstandings. In many places, it is customary to eat poached eggs in sugar water. In fact, when eggs and sugar are cooked together, the amino acids in the egg protein will form fructosyl lysine conjugates. This substance is not easily absorbed by the human body and can have adverse effects on health. There is another dietary taboo on eggs, which is that they cannot be eaten with rabbit meat. "Compendium of Materia Medica" says: "Eating eggs and rabbit meat can cause diarrhea." Rabbit meat is sweet, cold, and sour in taste, while eggs are sweet, mild, and slightly cold. Both contain some biologically active substances, which will react when eaten and irritate the gastrointestinal tract. tract, causing diarrhea.

Eggs cannot be eaten together with rabbit, goose and other meats.

Li Shizhen said in "Compendium of Materia Medica": "Eating eggs and rabbit meat can cause diarrhea." That's because rabbit meat is sweet, cold, sour and cold, while eggs are sweet, mild and slightly cold. Both contain some biological substances. Active substances will react when eaten, irritating the gastrointestinal tract and causing diarrhea.

Don’t eat turtle meat immediately after eating eggs

There are many taboos about eggs, which are rarely known because they are rarely paired with them. For example, eating turtle meat after eating eggs can also cause food poisoning. Turtle meat itself is greasy in nature, so people with colds or cold and dampness in the body generally should not eat it. In addition, it has a mediocre nature, so pregnant women and people with poor digestive systems after giving birth should not eat it.

Do not take anti-inflammatory drugs immediately after eating eggs

Eggs are rich in protein. When inflammation occurs, special attention should be paid to protein intake. So when inflammation occurs, remember not to take medicine after eating eggs. Especially those with digestive tract diseases and diarrhea symptoms should not eat eggs. Because eggs contain a lot of protein, they will increase the burden on the gastrointestinal tract and have a relatively negative impact on the efficacy of the medicine, especially for steatorrhea. If it is other inflammations, such as the respiratory system, urinary system, etc., it will not have much impact from the perspective of Western medicine.

Don’t drink tea immediately after eating eggs

Many people like to use tea to relieve greasiness after eating eggs. Especially those who like to drink morning tea to wake up. But at this time, you actually overlooked one point, that is, drinking tea after eating eggs is harmful to health. Because tea contains a large amount of tannic acid, tannic acid and protein synthesize astringent tannic acid protein, which slows down intestinal peristalsis and prolongs the retention time of feces in the intestine. It not only easily causes constipation, but also increases toxic substances and carcinogenesis. The possibility of substances being absorbed by the human body and endangering human health.

Avoid eating undercooked eggs

Egg protein contains avidin, which will affect the absorption of biotin in food, causing loss of appetite, general weakness, muscle pain, skin inflammation, Symptoms such as eyebrow loss. Eggs contain antitrypsin, which affects the body's digestion and absorption of egg protein. These two substances in undercooked eggs have not been broken down, thus affecting the digestion and absorption of protein.

Eggs will carry bacteria during the formation process. Uncooked eggs cannot kill bacteria and can easily cause diarrhea. Therefore, eggs should be eaten after they have been heated to high temperatures, and do not eat undercooked eggs.

The protein structure of raw eggs is dense, and a large part of it cannot be absorbed by the human body. Only when cooked, the protein becomes soft and can be digested and absorbed by the human gastrointestinal tract. Raw eggs have a special fishy smell, which can cause central nervous system depression and reduce the secretion of digestive juices such as saliva, gastric juice, and intestinal juice, leading to loss of appetite and indigestion.

Food taboos

Eggs and rabbit meat are incompatible with each other. Each contains some biologically active substances. If they are fried and eaten together, it is easy to produce substances that irritate the gastrointestinal tract and cause diarrhea. Therefore Not suitable for eating together.

Eggs are incompatible with raw onions and garlic. Onions, garlic and eggs are inconsistent in nature, taste and function.

Eggs and soy milk are in conflict with each other, reducing their nutritional value.

Eggs and sweet potatoes are incompatible with each other, making them more difficult to digest when eaten together

Eggs and MSG are incompatible with each other, which will cause excessive glutamate intake, which is bad for digestion and nervous system.

Eggs and beans are in conflict with each other

Not suitable for eating raw

Eggs contain more than 10 kinds of proteins. After the eggs are cooked, the unique rules of the polypeptide chains in the protein molecules The arrangement changes and becomes a more chaotic arrangement. This is the denaturation of the protein. Because the spatial structure of the denatured protein has been disrupted, it is easier to decompose than the original orderly arrangement, so it is easily digested and absorbed by the human body.

Some people think that raw eggs are easier to digest and absorb and more nutritious than cooked eggs, which has no scientific basis. Eating raw eggs has the following disadvantages:

(1) Raw eggs are difficult to digest and waste nutrients. The body's digestion and absorption of protein in eggs mainly relies on pepsin and trypsin in the small intestine. There is an anti-trypsin substance in the egg white of raw eggs, which will hinder the digestion and absorption of protein. Boiled eggs are anti-trypsin. The substances no longer exist, so they are easily digested and absorbed by the human body.

(2) Raw eggs contain avidin and an antibiotic protein. If you often eat raw eggs, the avidin in them can make the vitamins in the food B loses its effectiveness, and antibiotic proteins will accumulate in the human body. If it accumulates too much, it will hinder the body's absorption of biotin, and biotin is one of the multivitamins needed by the human body. If the human body lacks biotin, it will suffer from loss of appetite and mental problems. Fatigue, skin inflammation, desquamation and hair loss, weight loss, affect people's health.

(3) About 10% of fresh eggs contain pathogenic salmonella, mold or parasite eggs. If the eggs are not If it is fresh, the infection rate will be higher. Bacteria can enter the eggs directly from the hen's ovary, or they can be contaminated by bacteria in the anus and enter the egg shell during laying, and then enter the egg through the pores on the egg shell. These bacteria are afraid of high temperatures. If you boil them for 8 to 10 minutes, the bacteria inside and outside the eggs will be killed.

The protein of eggs is rich in essential amino acids, and its composition ratio is suitable for the needs of the human body. Eggs are also a good source of vitamins and inorganic salts, and are a food with high nutritional value.

Some people like to eat raw eggs. I feel that the nutrients in eggs are destroyed when they are cooked, and I think eating them raw is better for the body than eating them cooked. In fact, this way of eating is not only unhelpful but harmful. First, eggs are produced from the ovaries and cloaca of chickens, and their ovaries and cloaca have a high bacterial infection rate, so the surface of the eggshell and even the yolk may have been contaminated by bacteria. Eating them raw can easily cause parasitic diseases, intestinal diseases or food poisoning. . Second, raw eggs also have a fishy smell, which can inhibit the central nervous system, make people lose appetite, and sometimes make people vomit. Third, raw egg whites contain a substance called antibiotics, which hinders the body's absorption of biotin contained in egg yolks. After eggs are cooked, they can kill bacteria inside and outside the eggs and destroy antibiotics, so eggs should not be eaten raw.

In many places, it is customary to eat poached eggs in sugar water. In fact, when eggs and sugar are cooked together, the amino acids in the egg protein will form fructosyl lysine conjugates. This substance is not easily absorbed by the human body and can have adverse effects on health.

Eating an egg when drinking soy milk in the morning, or boiling eggs in soy milk, is also the eating habit of many people. Soy milk has a sweet and mild taste, and contains many nutrients such as plant protein, fat, carbohydrates, vitamins, and minerals. Drinking it alone has a strong nourishing effect. However, there is a special substance called trypsin, which combines with the egg pine protein in egg whites, which will cause the loss of nutrients and reduce the nutritional value of both.

Pay attention to the crowd

It can be said that eggs are both economical and indispensable food in our lives. However, eggs with such rich nutrition are not better if you eat more, nor are they good for human health. Everyone can eat it with confidence.

(1). Patients with kidney disease and patients with nephritis

Reduced kidney function and metabolism, reduced urine output, and all metabolites in the body cannot be excreted by the kidneys. If you eat too many eggs, you may Increased urea in the body can lead to aggravation of nephritis and even uremia. Eating eggs in patients with advanced hypertension can cause arteriosclerosis in the kidneys. People with systemic lupus erythematosus accompanied by renal damage and various chronic kidney diseases leading to chronic renal failure should eat eggs with caution or follow doctor's advice.

(2). Patients with high fever

The protein in eggs is complete protein and can be decomposed into the body to generate more heat. This is called the special dynamic effect of food. This special dynamic effect has the largest protein effect, and the effect of increasing calories can reach about 30%. Therefore, after patients with fever eat eggs, the body's heat production increases and heat dissipation decreases, which is like adding fuel to the fire and is not conducive to reducing fever.

In addition, patients with fever have reduced secretion of digestive glands and decreased activity of various digestive enzymes. They should eat a light diet and eat less high-protein foods.

(3). Hepatitis patients should not eat egg yolks

If hepatitis patients eat more egg yolks, it will increase the burden on the liver and be detrimental to recovery. Because egg yolk contains fatty acids and cholesterol, both fatty acids and cholesterol need to be metabolized in the liver. The liver is overburdened and is not conducive to recovery from hepatitis.

(4). First-time mothers

Eggs are often the staple food during confinement, but eating more eggs is not always better. It is best not to eat eggs within a few hours after delivery. Because the physical exertion during childbirth is high, there is a lot of sweating, there is insufficient fluid in the body, and the digestion ability decreases. If you eat eggs immediately after delivery, it will be difficult to digest and absorb, which will increase the burden on the gastrointestinal tract. At this time, it is better to eat semi-liquid or liquid food. Some mothers eat many eggs a day in order to enhance their nutrition. In fact, this is not good for the body. Three eggs a day is enough for the mother.

(5). Elderly people

Eggs contain high amounts of cholesterol. It is generally believed that cholesterol can lead to age-related diseases such as hyperlipidemia, coronary heart disease, and atherosclerosis. This has led to the saying that the elderly should not eat eggs. However, in recent years, some scientists have proved through experiments that although eggs contain cholesterol, they are also rich in lecithin. Lecithin has a therapeutic effect on cardiovascular diseases. The absorption of lecithin into the blood can change the cholesterol and fat particles in the blood. Small and remain suspended, thereby reducing the deposition of cholesterol and fat on blood vessel walls. Therefore, elderly people with normal serum cholesterol concentrations who eat one egg a day will not cause atherosclerosis, and the other nutrients in eggs can also bring many benefits.

(6). People with protein allergies

Some people will have stomach pain or rash after eating eggs, which is caused by egg allergy. The protein in eggs is antigenic and can cause allergic reactions by interacting with sensitized mast cells carrying antibodies on the surface of the gastrointestinal mucosa. Mast cell granules release chemical substances such as histamine, which can cause congestion, edema, and gastrointestinal spasm in the gastrointestinal mucosa, causing stomach or abdominal pain, diarrhea, rashes and other allergic symptoms. Therefore, not eating eggs or foods containing egg ingredients is the most effective method of prevention and treatment.

3. Sweet potato (scientific name: Ipomoea batatas), also known as sweet potato, sweet potato, potato, sweet potato, sweet potato, red potato, thread potato, white potato, golden potato, sweet potato, red potato, pillow potato, etc. . A common perennial dicotyledonous plant, herbaceous, with slender vines and creeping stems. The roots produce lactic acid through anaerobic respiration. The skin color is white or red, and the flesh is mostly yellow-white, but some are purple. In addition to being used for food, it can also be used to make sugar, wine, and alcohol.

Consumption taboos

Experts point out that sweet potatoes should be best eaten during lunch time. This is because after we eat sweet potatoes, the calcium contained in them takes 4 to 5 hours to be absorbed by the human body, and afternoon sunlight can just promote the absorption of calcium. But it is best to eat sweet potatoes before lunch, so that the calcium can be fully absorbed before lunch and will not affect the absorption of calcium from other foods at dinner.

When we process sweet potatoes, we must steam them thoroughly to destroy the cell membrane of starch, which is a substance that is difficult to digest. Also, if the gasification enzymes in sweet potatoes are not destroyed by high temperatures, we will feel uncomfortable after eating them. [3]

1. It is not advisable to eat sweet potatoes with black spots. The black spot virus in sweet potatoes with black spots is not easily destroyed and killed by high temperatures and can easily cause poisoning and symptoms such as fever, nausea, vomiting, and diarrhea. A series of poisoning symptoms can even lead to death.

2. It is not advisable to eat it at the same time as persimmons. The main component of sweet potatoes is starch. After eating, a large amount of fruit acid will be produced. If eaten at the same time as persimmons, the fruit acid can coagulate with the tannins and pectin of the persimmons. Formation of stomach stones. If you eat a lot, the interval should be at least five hours. If eaten at the same time, the sugar in sweet potatoes will ferment in the stomach, which will increase gastric acid secretion and react with the tannins and pectin in persimmons to precipitate and condense, producing hard lumps. In severe cases, it can cause gastrointestinal bleeding or gastric ulcers. If you feel stomach discomfort, be sure to go to the hospital for a gastroscopy to see if there is gastric bleeding or gastric ulcers.

3. Sweet potatoes should be eaten in moderation.

Sweet potatoes contain an oxidase, which easily produces a large amount of carbon dioxide gas in the human gastrointestinal tract. If you eat too much sweet potatoes, it will cause abdominal distension, burping, and farting. Sweet potatoes are high in sugar, and eating too much can produce a lot of stomach acid, making people feel "heartburn."

The stomach contracts more due to stimulation by the acid. At this time, the cardia muscle at the junction of the stomach and the esophagus relaxes, and the acid in the stomach flows back into the esophagus, causing the person to vomit acid water. If there is too much sugar, the body cannot absorb it all for a while, and the rest will ferment in the intestines, which will also make the stomach uncomfortable.

Therefore, the popular sweet potato regimen is not suitable for everyone. If you have symptoms of diarrhea after eating it, don’t force it. Switching to brown rice will have the same effect.

4. Do not eat the skin of roasted sweet potatoes.

There are also roasted sweet potatoes now sold in streets and alleys. You can smell the sweetness of sweet potatoes from a long way away, so sometimes you can’t resist the temptation at all, and the skin of roasted sweet potatoes is burnt. It is very popular with everyone, and many people eat it with the skin on. However, experts point out that it is best not to eat roasted sweet potatoes with their skins on. Sweet potatoes contaminated by black spot pathogen are difficult to identify after roasting. Therefore, do not eat sweet potatoes with black spots or burnt ones, as they may cause poisoning.

Precautions for sweet potatoes

(1) Do not eat them raw

The starch in raw sweet potatoes is difficult to digest, so they must be steamed or roasted. It is recommended to use steaming method instead of frying.

(2) Eating sweet potatoes as porridge will prevent gastrointestinal bloating

Sweet potatoes can easily produce a large amount of carbon dioxide gas in the gastrointestinal tract. If you eat too much, it will cause bloating and burping; sweet potatoes There is a lot of sugar in it, which accumulates in the intestines and ferments, which can also cause discomfort such as bloating.

When eating sweet potatoes, it is best not to drink water while eating, or add a small amount of sweet potatoes to rice to make porridge, which can reduce gastrointestinal discomfort.

(3) Foods that are beneficial to patients with skin allergies:

Supplement more vitamin C. Because lack of vitamin C can easily make the skin rough and dry, leading to dermatitis, peeling and other sensitive damages. Among fruits and vegetables rich in vitamin C, pears and kiwis are better. Eating more can strengthen skin tissue and help fight external allergies; consume herbal tea and other foods that can clear away heat and reduce inflammation. Sweet potatoes are rich in nutrients, including protein, fiber, vitamins, etc., which are needed by people with skin allergies. Therefore, people with skin allergies can eat sweet potatoes.

Efficacy

Enhance skin resistance. The skin is also a member of the human immune system and is the body's first barrier against external aggressions such as bacteria and viruses. Vitamin A plays an important role in the process of connecting skin tissue. The best way to supplement vitamin A is to obtain beta carotene from food. Sweet potatoes are the fastest way to obtain this nutrient. They are rich in beta carotene and are low in calories.
