In early spring, the temperature is still cold, and the human body needs to consume some energy to maintain the basal body temperature to keep out the cold. Therefore, the nutrients in early spring should be mainly high in calories. In addition to cereal products, you should also choose foods such as soybeans, sesame seeds, peanuts and walnuts to supplement energy substances in time. Because the cold stimulation will accelerate the decomposition of protein, which will lead to the decline of body resistance and cause diseases, it is necessary to supplement high-quality protein foods such as eggs, fish, shrimp, beef, chicken, rabbit meat and bean products in early spring. The above foods are rich in methionine, which can enhance the cold tolerance of human body.
Spring is also the season when the climate changes from cold to warm, and the temperature changes greatly. Bacteria, viruses and other microorganisms begin to multiply in large numbers, and their vitality is enhanced, which is easy to invade the human body and cause diseases. Therefore, we should take enough vitamins and inorganic salts in our diet. Fresh vegetables such as Chinese cabbage, rape, persimmon pepper and persimmon, and fruits such as citrus and lemon are rich in vitamin C and have antiviral effects. Yellow-green vegetables such as carrots and amaranth are rich in vitamin A, which can protect and increase the epithelial cells of the strong upper respiratory mucosa and respiratory organs, thus resisting the invasion of various pathogenic factors; Food rich in vitamin E should also be eaten to improve human immune function and enhance the body's disease resistance. This kind of food includes sesame, blue cabbage and cauliflower.
Motherland medicine also believes that "spring should be sour and sweet to nourish the temper." This is because when the liver qi is strong in spring, it will affect the spleen, so it is easy to appear spleen and stomach weakness in spring; Moreover, eating more sour food will make the liver function high, so the spring diet should be nursed back to health, and it is advisable to choose spicy and warm products to avoid acidity. Diet should be light and delicious, avoid greasy, cold and irritating food. In addition, spring is the off-season of vegetables, but the growth period of wild vegetables and mountain vegetables is earlier than that of ordinary vegetables, and they are rich in vitamins, so they can be picked and eaten to supplement the shortcomings of ordinary vegetables.
Cool fruit relieves dryness and heat
Fruits in summer are mostly cold, such as pears, apples and melons. Generally speaking, people with excessive heat constitution have vigorous metabolism in summer, dominant sympathetic nerves, sweating more, often blushing, dry mouth, irritability and constipation, and especially like to eat cold things in summer.

Apples, for example, are sweet and have the functions of stopping diarrhea, relaxing bowels and helping digestion. Eating regularly can make the skin white and tender. However, because it is rich in sugar and potassium salt, eating too much will be harmful to the health of the heart and kidneys. Patients with coronary heart disease, myocardial infarction, nephritis and diabetes can't eat more, and those with insufficient middle qi and mental fatigue can eat more as nourishing fruit.
Pears, oranges, grapefruit and other fruits have the functions of relieving cough and resolving phlegm, moistening the lungs and helping digestion, but eating too much can easily cause gastrointestinal discomfort, toothache, hemorrhoids and even skin rash. Therefore, people with stomach trouble and cold stomach had better eat less.
People with qi deficiency and spleen deficiency should be especially careful when choosing cold fruits such as watermelon, cantaloupe, mango, pear and banana, and it is best not to eat them. Qi deficiency generally refers to people or children with insufficient qi and weak strength. Such people are generally pale, thin and unable to eat; Spleen deficiency means poor digestive system and slow intestinal peristalsis. Therefore, the more you eat cool fruit, the more you will reduce gastrointestinal peristalsis and make your muscles weak. Eating too much will lead to bloating due to indigestion. Therefore, the elderly and children with poor gastrointestinal function are not suitable for eating cold fruits. If they really want to eat, they can eat less after lunch and before dinner, but not too much.

Warm fruits tonify deficiency and cold.
Although there are many cool fruits in summer, among many fruits, such as litchi, longan and apricot, which are warm, they are still popular. Especially people with deficiency-cold constitution have deficiency of qi and spleen, low basal metabolic rate, less heat generated in the body, and their limbs are cold even in summer. Comparatively speaking, these people are whiter than ordinary people, and they are seldom thirsty, and they don't like touching cold things, including entering air-conditioned rooms. Therefore, it is undoubtedly a good cold tonic for these people to eat more warm fruits.
However, for most people, eating too much warm fruit in hot weather is easy to get angry. For example, litchi contains hypoglycemic ingredients, and if you eat too much, you will have a low-sugar reaction. For people with hot constitution, they can't eat warm fruits because they are full of energy, difficult to fall asleep at night and have high metabolic rate. In addition, children with fever or inflammation of an organ should try to avoid eating it.

Fruit is the main source of vitamins A and C in people's diet, and most fruits are healthy foods. Pectin contained in fruit has the function of dietary fiber, and fruit is also indispensable for maintaining acid-base balance and electrolyte balance. According to expert analysis, the term "gold, silver and copper" means that eating fruit in the morning has the highest nutritional value and eating fruit at night has the lowest nutritional value. The reason is that when people get up early, the liver sugar supply to the brain runs out, so eating fruit can supplement sugar as soon as possible. And eating fruit in the morning, all kinds of vitamins and nutrients are easily absorbed.
But in terms of digestion, people with stomach problems should not eat fruit on an empty stomach in the morning. Professor Huang also pointed out that we should pay attention when choosing to eat fruit. I don't mean that I ate very well in the morning, but I ate very badly in the evening.
Eating before meals is good for stimulating appetite, and eating after meals is good for the digestion and absorption of things. Fruit itself contains enzymes. If you want enzymes to produce different effects in the body, it is best to consider the time of eating, depending on the situation of different individuals. For example:
Banana: Banana has high potassium content, which is beneficial to the function of heart and muscle. At the same time, bananas can help treat constipation and diarrhea in children. Suitable for eating before meals.
Pineapple: Fresh pineapple contains protease. If you eat on an empty stomach, the proteolytic enzyme of pineapple will damage the stomach wall. A few people will also cause allergic reactions and should eat after meals.
There are three bad ingredients in pineapple, which may bring trouble to people:
Glycosides are organic substances, which are irritating to human skin and oral mucosa. Therefore, the mouth will feel itchy after eating untreated raw pineapple, but it is not directly harmful to health. Serotonin is a nitrogen-containing organic substance, which has a strong effect on vasoconstriction and blood pressure increase. Every 100g fruit juice contains 2.5 mg ~ 3.5 mg. The first reaction after eating too much is a headache. Bromelain is a protein hydrolase. After extraction, it has a strong function of decomposing fibrin and blood clots, which is useful in medical treatment. A small amount of protease in pineapple is decomposed and destroyed by gastric juice after being eaten in the stomach. But a few people are allergic to this enzyme. Abdominal pain, nausea, vomiting, urticaria (commonly known as rash), headache, dizziness and other symptoms occurred about 15 ~ 60 minutes after eating. In severe cases, dyspnea and shock may occur. The so-called pineapple allergy refers to this.
Persimmon: Persimmon contains a lot of persimmon powder and red tannin. If you eat on an empty stomach in the morning, stomach acid will react with it to form a blood clot, which will seriously affect the digestive function. Suitable for eating after meals or at night.
Hawthorn: Hawthorn, whether it is fresh fruit or its products, has the effects of removing blood stasis, resolving phlegm and detoxifying, heatstroke prevention and cooling, and stimulating appetite. However, people who eat on an empty stomach or have weak spleen and stomach should not eat in the morning, and people with gastritis and hyperacidity should also eat less.
Jujube: It contains a lot of vitamin C, so it has the reputation of "natural vitamin C pills". However, people with stomachache, bloating and indigestion should avoid eating, and it is recommended to eat before meals.
In addition, people of different ages, especially the elderly, should pay more attention when choosing fruits. Fruit is rich in vitamins, trace elements and various nutrients. Old people often eat fruit, which has the effects of nourishing and strengthening the body and prolonging life. But the elderly must know the following points when eating fruit:
It is not always better for the elderly to eat more fruits.
Most fruits contain fructose. Excessive intake by the elderly will lead to the lack of copper in the body, which will lead to the occurrence and development of cardiovascular diseases. In addition, the elderly have poor digestive ability, gastric mucosa atrophy and intestinal peristalsis weakened. Excessive intake will cause digestive dysfunction, which is not conducive to the health of the elderly. Therefore, the elderly should not only eat fruits regularly, but also not eat too much at one time.
Don't eat fruit at will.
Apples and pears contain a lot of fructose, so the elderly with diabetes and nephritis should not eat more; Bananas and cantaloupes contain high potassium salt, and the elderly with nephritis and edema diseases will aggravate their condition if they eat more; Watermelon, pear and other fruits are cold, and the elderly with weak spleen and stomach will cause gastrointestinal dysfunction, abdominal pain and diarrhea if they eat too much; Pineapple contains bromelain, which often makes some elderly people allergic to pineapple and harms their health. Old people have little activity, slow intestinal peristalsis and frequent habitual constipation. Persimmon contains a lot of persimmon gum phenol, which will aggravate constipation for the elderly. Citrus is warm, and it is easy to get angry if you eat too much. Therefore, the elderly need to scientifically choose beneficial and harmless fruits to eat according to their own health conditions.
It is not advisable to eat apples immediately after meals.
The content of thiocyanate in vegetables is high, especially radish, Chinese cabbage and cauliflower. Thiocyanate can form thiocyanate in reflecting human metabolism. And bright fruits such as apples, pears and grapes all contain a certain amount of flavonoids. This compound is decomposed by bacteria in the intestine and converted into trihydroxybenzoic acid. Hydroxybenzoic acid and thiocyanate can interfere with the thyroid function of the elderly, leading to non-iodine deficiency goiter and affecting the normal physiological metabolism of the elderly. Experts believe that the best time to eat fruit should be before meals 1 hour and 2-3 hours after meals.
Moldy fruit can't be eaten.
Fruit is high in water content, suitable for mold growth and easy to mildew. In recent years, it has been found that moldy fruits contain a kind of toxin-Zhan Qing toxin, which is very toxic and people should not take it lightly.
The fruit is attacked by mold, the peel softens, forms diseased spots, sinks and the pulp is soft and rotten. Mold grows and reproduces in the pulp and produces toxins. According to the determination, toxins can still be detected in the normal dental pulp at a distance of 1 cm from the decaying site. Therefore, the Peking Opera with fruit should be bright, crisp, fragrant and full of moisture. If there is a little spot or a small amount of insect-eaten, use a knife to dig out the rotten insect-eaten place and the good fruit parts around it above 1 cm. Fruits that rot or are eaten by insects over 1/3 or have bitter taste are inedible. The dry climate in winter often makes people feel dry and uncomfortable with their noses and throats. At this time, if you can eat some fruits that can quench your thirst and moisten your throat, it will make people feel refreshed and comfortable.
Pears and sugarcane are health care and medicinal fruits in winter. Chinese medicine believes that pear has the functions of promoting fluid production to quench thirst, relieving cough and resolving phlegm, clearing away heat and reducing fire, nourishing blood and promoting granulation, moistening lung and removing dryness, and is most suitable for patients with internal heat in winter. It is especially suitable for cough due to lung heat, wind-heat in children, dry throat and sore throat, and dry stool.
Modern medical research believes that pears also have the functions of lowering blood pressure, clearing away heat and calming the nerves. Patients with hypertension such as dizziness, palpitation and tinnitus often eat pears, which can relieve symptoms. Pears are rich in sugar and vitamins, which can protect the liver and help digestion. Therefore, it is very beneficial for patients with liver cirrhosis to eat it as a medicinal food. There is a folk proverb that "a few apricots and peaches have three fires, but there are not many pears in the eclipse", which shows that eating more pears is beneficial and harmless. However, due to pear cold, it has certain curative effect on those diseases such as spleen and stomach deficiency cold, indigestion, postpartum high fever and polydipsia. Therefore, it is called "Tianshengfumai Decoction". People who are overworked or dizzy from hunger will refresh themselves as long as they eat two sugar cane.
However, due to the cold nature of sugarcane, it is not suitable for people with spleen and stomach deficiency and stomachache. In addition, apples, oranges, bananas and hawthorn are all suitable for winter consumption. Apples can produce fluid to quench thirst, regulate spleen and stop diarrhea; Oranges can regulate qi, stimulate appetite, promote digestion and resolve phlegm; Bananas clear away heat and moisten intestines, lower blood pressure and prevent hemorrhoids; Hawthorn can dilate blood vessels, reduce blood lipid, enhance and regulate myocardial function, and has the effect of preventing and treating coronary atherosclerosis.
