All physiological activities in the human body need a relative balance of pH, and if it is out of balance, it will cause diseases. Under normal circumstances, human blood remains weakly alkaline (PH value is between 7.35 and 7.45), and when it is acidic, it is called acidic constitution; When the alkalinity is high, it is called alkaline constitution.

The acid-base balance of human constitution is the result of normal metabolism of substances, which is closely related to the acidity and alkalinity of diet and food intake. The pH of food depends on the types and quantities of elements contained in food. Foods containing most phosphorus, sulfur, chlorine and other elements are called acidic foods, including barley, corn, flour, peanuts, walnuts, sticks, sugar, white rice, brown rice, wine, meat, chicken, duck, egg yolk, fish, shrimp, crab, shellfish and so on. Foods containing calcium, sodium, potassium, magnesium and other elements are called alkaline foods, including soybeans, red beans, mung beans, broad beans, peas, vegetables, fruits, chestnuts, lotus roots, lilies, milk powder, egg whites, kelp, Undaria pinnatifida, tea, coffee and so on. In people's daily diet, because the staple food is acidic food, if you eat more acidic foods such as meat, eggs and aquatic products, it will easily exceed the required amount, or because of long-term consumption of white sugar and excessive drinking, it will easily lead to acidic blood, which will not only increase the consumption of alkaline elements such as calcium and magnesium, but also cause calcium deficiency in human body and increase the viscosity of blood, causing various acidosis. Children are prone to acidosis, dermatosis, neurasthenia, fatigue, hyperacidity, constipation, dental caries, rickets and so on. The elderly are prone to diseases such as hypertension, arteriosclerosis, gastric ulcer and cerebral hemorrhage.

In daily life, we should eat more alkaline foods such as vegetables and fruits, control the proportion of acidic foods and balance the pH value. This can not only prevent diseases caused by acid-base imbalance, but also help to fully absorb and utilize various nutrients in food. Especially in festive occasions, banquets and dinners, people usually eat acidic foods such as meat, fish, poultry and eggs, and should pay more attention to the intake of alkaline foods to keep healthy. For patients with kidney disease, liver disease, traumatic blood loss, dehydration, hypoxia, infection and other diseases, it is more appropriate to eat more fruits, seaweed and vegetables to neutralize excessive acidic metabolites in the body. Drinking tea is also a good way to maintain normal alkalinity in the body.

Diet during the trip

Tourism is a fitness and entertainment activity that cultivates temperament, exercises and increases knowledge. Due to the changes of climate, environment and living habits, climbing mountains and wading in tourism consumes a lot of physical strength and energy. Therefore, it is very important to arrange diet during the tour. How to make tourists eat scientifically and reasonably? The most important thing is not to eat famous dishes, but to have enough calories to stimulate appetite and facilitate digestion and absorption. The frequency and time of eating should not disturb the original law of life, so as to give full play to the best digestion and absorption function under the original conditioned reflex. For example, if you go hiking on a mountain that consumes too much physical strength, you should supplement nutrition. Might as well bring some salty food such as tea eggs, which can not only resist hunger, but also supplement salt. Besides dry food, boiling a pot is also essential.

It is not good for tourists who are carsick and seasick to eat too much. To avoid dizziness and vomiting, you should eat moderately and lightly. Folk ginger slices can be stuck on both sides of the wrist to prevent dizziness (or on the navel), so try it.

A healthy diet is very important for tourists. Because tourists are often tired and dissatisfied with the water, their physical resistance is temporarily reduced. If they don't pay attention to hygiene, they are more likely to catch gastrointestinal infections, especially if they don't drink raw water. If they are thirsty and have no clean water to drink, they can eat fruits and vegetables after peeling. Food must be cooked, especially fish, shrimp and other meat-like foods, which are easy to deteriorate. If you don't pay attention to hygiene, it will cause food poisoning.

It's best to take a small bottle of vinegar when traveling, and a spoonful of warm water before departure, which can alleviate the symptoms of carsickness. If you have diarrhea, you can also use vinegar and salt to decoct with boiling water; Burping after meals can also be used to deal with it; When you are tired, you can also wash your body with vinegar in the bath water to relax your muscles. Vinegar can also prevent colds. Put a spoonful of vinegar into a cup of hot water and inhale deeply into the mouth of the cup to inhibit or kill bacteria and viruses on the upper respiratory mucosa.

First of all, add protein. On the premise of sufficient total calories, there should be various and rich high-quality protein foods in the diet, including fish, shrimp, poultry, eggs, chickens, ducks, mutton, beef, pork and bean products.

Second, adequate vitamins. Try to eat more peas, lentils, potatoes, pumpkins, Gan Lan, green garlic, Chinese dates, cauliflower, lettuce, carrots, tomatoes, potherb mustard, green leafy vegetables, animal livers, vegetable oils and oranges.

Third, inorganic salts are indispensable. Because calcium, phosphorus, iron, iodine, zinc, sulfur, chromium, selenium and other elements in traditional diet and existing diet are often insufficient. Therefore, newlyweds should eat more foods containing these elements, such as wax gourd, broad bean, onion, garlic, fungus, kelp, laver, fish and shrimp, sea cucumber, eggs, brown sugar, grapes, yam, walnuts, longan, honey, day lily, bone soup, etc., and the calcium supplement should not be less than 700 mg per person per day. If it is lacking, there will be symptoms such as low back pain, leg pain and pelvic pain after sexual life, such as eating some foods such as tofu, soybean milk, shrimp skin and sesame sauce every day.

Newlyweds are forbidden to drink too much during the wedding, especially not to have sex after drinking, so as to avoid giving birth to mentally retarded children with dementia and affecting the health of the next generation.

Menopausal syndrome diet

Both men and women, in the process of transition from middle age to old age, with the gradual growth of age, the endocrine function in the body also decreased accordingly. Some symptoms caused by this physiological change are called menopausal syndrome.

The menopause of women is mainly marked by menopause, which is related to ovarian dysfunction. After ovarian function declines, estrogen secretion loses its periodicity, leading to menstrual disorder. Then, when the follicular development stops and the secretion of estrogen gradually decreases to the point where it cannot stimulate the endometrial response, menopause occurs. Its common symptoms are: ① menstrual changes: at first, menstrual cycle is disordered, menstrual volume decreases or increases, menstrual period is shortened, menstrual cycle is prolonged, and then it is irregular and gradually stops. ② Autonomic nerve dysfunction: paroxysmal facial flushing, head and neck swelling, irritability, nervousness, irritability, depression, insomnia and even moodiness. ③ Cardiovascular system dysfunction: palpitation, chest tightness, tachycardia or bradycardia, increased blood pressure and increased incidence of atherosclerotic heart disease. ④ Metabolic dysfunction: obesity, hyperglycemia, osteoporosis, decalcification, and even elderly women are prone to fracture and slow recovery. ⑤ Changes of sexual organs: The external genitalia began to shrink, and the vaginal intima became thinner, which made it easy to suffer from vaginitis.

Men also have menopausal syndrome, but the performance is different. Generally, he said that male climacteric syndrome appeared later than female, with mild symptoms and even few manifestations. Generally, it is characterized by unstable cardiovascular symptoms, such as premature beats and blood pressure fluctuations. Mental and neurological symptoms include impatience and irritability, but some people, on the contrary, become taciturn, emotionally eccentric, suspicious, moody, nervous, anxious, headache, insomnia, memory loss, fatigue, loss of libido and physical appearance.

Here is an introduction to the diet of male menopause, mainly to eat more foods that improve and enhance gonadal function. After improving and enhancing gonadal function, it will fundamentally relieve various symptoms of male menopause. These foods include: shrimp, mussels, mutton, sheep kidney, sparrows, leeks, walnuts, etc., such as fried leeks with shrimp, fried lamb loin with Eucommia ulmoides, stewed mutton with cistanche, stewed duck with Cordyceps sinensis, sparrow porridge, ginseng wine, and yipin yam. Secondly, eat more foods that can improve nervous system function and cardiovascular function, such as sheep heart, pig heart, bighead carp, yam, walnut kernel, jujube, longan, mulberry, sunflower seeds, yellow wine walnut soup, mulberry honey cream, walnut porridge, ginseng jujube rice, yam milk soup, roasted sheep heart with roses and so on. Helps to treat headache, dizziness, fatigue, palpitation, shortness of breath, etc. Patients with menopausal syndrome should not eat disorderly and unbalanced food, and should not eat soaking, irritating and pepper-flavored food.

Diet of middle-aged people

Middle-aged people often think that their bodies are in a vigorous life period, but they ignore the scientific and reasonable adjustment of diet. As we all know, the life course of human body is bounded by 40 years old. After the age of 40, the body gradually turned from prosperity to decline. Only when you enter old age can you feel the harm caused by careless diet in middle age. Therefore, in order to live a long and healthy life, we should pay attention to the scientific arrangement of diet from middle age.

Middle-aged people and young people have the same needs, and they need to regularly ingest and supplement six nutrients, namely protein, sugar (including sugar and starch), esters, minerals, vitamins and water. However, after middle age, due to a series of physiological changes, especially the decline of digestion and metabolism, the demand for various nutrients is very different from that of young people. Therefore, the diet of middle-aged people needs to be adjusted to meet the needs of the body. For example, sugar is a food that needs to be reduced. According to scientific research, sugar is the main source of human body heat, and physical activity is decreasing after middle age. Therefore, sugar, one of the sources of heat, must also be reduced. The daily appetite is enough to meet the body's energy needs. If you eat some greasy food, you will have excess energy, so the liver will convert the excess energy into fat and store it everywhere. Therefore, middle-aged people must adhere to six taboos in diet:

First, don't eat too much. According to the requirements of maintaining a low-calorie diet every day, you can eat less and eat more meals, and you can eat 70% to 80%.

Second, avoid drinking less water. Water is one of the six nutrients, and three-quarters of human tissues are composed of water. Insufficient drinking water will reduce blood circulation, pulse and respiration, and reduce the function of digestive organs, which will lead to constipation. Therefore, it is recommended to drink plenty of water, especially a cup of warm water in the morning, which is more conducive to cleaning the stomach and promoting the excretion of waste. Of course, there should be a limit to drinking water. Too much is not good, which will dilute the blood concentration, increase the blood volume of the human body, and cause an excessive burden on the cardiovascular system and kidneys.

Third, avoid partial eclipse. Every food has its nutrients, and they all provide the nutrients needed by the human body, so that the acidity and alkalinity needed for physiological activities in the body are relatively balanced and diseases are avoided. If you just eat more food and always keep a distance from other foods, it will inevitably make the pH in the diet out of balance, which will inevitably lead to diseases due to insufficient acid and alkali.

Fourth, avoid obese people. Middle-aged people had better keep a certain weight. If you are overweight, you should pay attention to reducing food appropriately. Judging from the trend of weight increase and decrease, people are prone to obesity in middle age, but obesity is the source of all diseases in middle-aged and elderly people. Such as hypertension, arteriosclerosis, heart disease, diabetes, etc., are closely related to obesity.

5. Avoid eating more sweets and sugar. Sugar is one of the sources of human energy, and 70% of the energy of human activities is provided by sugar, but the impact of too much sugar on health is also very obvious. The occurrence of cardiovascular diseases in middle-aged and elderly people is related to eating too much sugar and sweets. Due to excessive intake of sugar, there are more cholesterol and triglycerides in the blood, which leads to cardiovascular diseases and obesity. Diabetes is related to eating too much sugar. Hostile middle-aged people should avoid eating more sweets and sugar.

Six, avoid eating greasy food. After middle age, animal fat can only be eaten in moderation, not in excess, because these neutral fats contain saturated fatty acids, which are easy to combine with cholesterol and deposit on the blood vessel wall, leading to arteriosclerosis and coronary heart disease.

The diet of the elderly

Good nutrition is the material basis of anti-aging, and scientific diet is an effective means to prevent senile diseases.

According to the living conditions of China people, in line with the principle of "eat well in the morning, eat well at noon and eat less at night", combined with the daily calories and various nutrients needed by the elderly, the daily food intake is listed as follows for reference:

Daily intake of 0.25 kg of milk, one egg, lean meat100g, tofu100g, 0.5 kg of vegetables, 300-350g of various rice or flour, 30g of edible oil (preferably vegetable oil) and 0/0g of sugar/kloc-0. The distribution in each meal is:

Breakfast: milk or soybean milk 0.25kg, rice flour food 100g, vegetables 100g, edible oil10g;

Chinese food: staple food 125g, lean meat 100g, vegetables 200g, cooking oil15g;

Dinner: 25 grams of porridge, 50 grams of steamed bread, 0/00 grams of tofu/kloc, 50 grams of one egg or lean meat, 200 grams of vegetables and 5 grams of oil;

The diet of the elderly should pay attention to: ① supply sufficient calories and various nutrients. Neither too much nor lack, to avoid obesity, not malnutrition; Eat more protein foods with high nutritional value, such as milk, lean meat, fish and shrimp, bean products, etc. (3) Eat as many fresh vegetables and fruits as possible according to the digestive ability of the elderly and their requirements for high vitamins and cellulose; (4) Change the dietary pattern frequently, increase the types of food, and prevent monotonous diet from affecting appetite and food intake; 5 Try to be light and never eat greasy or salty food; 6. When cooking food, pay attention to softness and facilitate chewing. Easy to digest and absorb; ⑦ Don't eat too much per meal, and it is advisable to be eight points full, and avoid overeating or uneven hunger; Develop the good habit of eating regularly and quantitatively, and add meals between meals when necessary; Eat more foods containing calcium and iron, such as milk, kelp, shrimp skin, liver, eggs and fish.

The diet of the elderly should not:

First, avoid eating irregularly, quantitatively, often full or hungry.

Second, don't eat hard food. Because the teeth of the elderly are loose or fall off, the digestive function is reduced. It is not advisable to eat hard food and fried food that are not easy to digest.

Third, avoid greasy and fatty foods to prevent hypertension and coronary heart disease in the elderly. Fourth, avoid eating salty food, prevent kidney burden and prevent hypertension.

Five, avoid partial eclipse, in case of malnutrition and illness.

6. Avoid eating foods that are too cold. Older people prefer warm food to cold food, so they should eat hot food instead of cold food.

Seven, avoid smoking, drinking tea properly can increase the elasticity and permeability of blood vessels and prevent hypertension, but tea should not be too strong to prevent insomnia.

Eight, avoid eating more sugar and foods with high sugar content to prevent diabetes and obesity. Because too much sugar overburdens islet cells involved in glucose metabolism, there is a long-term risk of diabetes, especially for people with a family history of diabetes. Excessive intake of sugar will also promote the production of neutral fat in the liver, and most of the neutral fat in the blood will be converted into subcutaneous fat, thus causing obesity and increasing the burden on the heart.

It's been a long time, for your health! !
