With the improvement of people's living standards, the range of nutritional diet choices is getting wider and wider, and it also brings nutritional imbalance. Excessive intake of meat, eggs and milk, less intake of vegetables and fruits. The accumulation of high fat, animal protein and sugar in people's lives threatens human health, and countless malignant and chronic diseases are showing a trend of rapid increase and younger age.
Nutritional imbalance is the biggest threat to human health. Spirulina is rich in plant protein, minerals, amino acids, vitamins and other nutrients. It is the most comprehensive and balanced food in the world, and its digestion and absorption rate is as high as 60%-70%. Even the elderly and children with low digestion and absorption rate can easily obtain all the nutrients.
The nutritional value of 1g spirulina is equivalent to the nutritional sum of 1000g of various vegetables and fruits. It has important nutritional value and far-reaching significance in balancing human nutrition.
Spirulina is rich and balanced in nutrition, which has special effects on the recuperation of patients with severe malnutrition, the recovery of the weak after illness, the enhancement of children's physique and the health care of the elderly. Human health is not maintained by drugs, but by balanced nutrition. As we all know, partial eclipse is an important factor causing unhealthy, and over-processed food often loses a lot of nutrition, and the lack of one nutrition will also lead to the lack of multiple nutrients. Spirulina is rich and balanced in nutrition, which can just supplement the deficiency of nutritional intake in food and is of great help to human health.
Spirulina and human health
Spirulina, as a resource for balancing protein, vitamins and minerals, is beneficial to human health and has health care function, and its importance has been recognized internationally. Many countries have used it as baby food, health food for the elderly and human nutritional supplements. With the deepening of research work, a large number of scientific studies have proved that spirulina has a variety of bioactive substances, which are helpful to human health, mainly in the following aspects.
enhance the vitality (of)
Protein is an important material foundation of human life activities. If the intake is insufficient, the human body will lose its vitality. Spirulina is rich in high-quality protein easily absorbed by human body. In particular, the contents of eight amino acids which are necessary for human body and cannot be synthesized by itself are almost consistent with the ideal standards designed by FAO. Spirulina can promote the formation of protein, which is the most ideal food to enhance vitality.
(B) to enhance physical fitness
Tests show that body fluids are acidic when people are sick, tired or weak. The most fundamental way to change acidic body fluids is to eat more alkaline foods. Spirulina is rich in a variety of alkaline minerals, which can effectively neutralize unhealthy acidic body fluids, fundamentally improve physical fitness, improve human anti-fatigue ability, and coordinate human regeneration and immunity.
(3) enriching blood and hematopoiesis
Spirulina contains a lot of iron, which is a reusable raw material for synthesizing hemoglobin. Combined with comprehensive nutrition such as protein, folic acid and vitamins, it is beneficial to iron absorption. In addition, abundant chlorophyll and vitamin B 12 are also the main components to promote the formation of hemoglobin. Appropriate supplement of spirulina can promote hematopoietic function, and help to increase the oxygen content in blood, and avoid the phenomenon of general fatigue, dizziness and headache.
(4) Radiation resistance
Spirulina contains a special photosynthetic pigment protein-phycocyanin, which can improve the radiation resistance of human body and avoid the radiation damage of TV, microwave oven, computer and mobile phone.
(5) Spirulina and diabetes
Diabetes is a typical "rich disease". From the point of view of nutrition, if people eat too much animal protein, the calories are too high, or the carbohydrate metabolism in food is abnormally converted into glucose, which is excreted from urine, it is easy to cause diabetes. Diabetic patients lack vitamin B6 and magnesium. Without the help of magnesium, vitamin B6 cannot be absorbed by human body. When the human body has too little vitamin B6, the tryptophan it chews is not only beneficial to the human body, but will turn into yellow urea. When the blood yellow urea is too high, it will damage the pancreas and cannot secrete insulin, so it is usually necessary to supplement insulin to patients, but this method is passive. The active method should be to restore the insulin secretion function of pancreas by improving nutrition. In order to prevent and improve diseases, we should first pay attention to diet to keep the balance of various nutrients in the body.
Spirulina is effective in treating diabetes, because it is an ideal food with high protein and low calorie. Spirulina contains high content of chlorophyll (1.33% is magnesium compound), rich plant protein (60-70%), vitamin B 1 for improving sugar metabolism, vitamin B2 for preventing fat oxidation, vitamin B6 for promoting insulin synthesis, and high content of potassium (1.5) for helping insulin secretion and neutralizing pyruvate to prevent pyruvate poisoning. At present, doctors in the United States and many western European countries have listed spirulina as an experimental drug and a routine supplementary food for diabetes.
(6) Spirulina and acidic constitution
The original habitat of spirulina is a lake with high alkalinity. With the development of modern science and technology, spirulina has become a high-grade food-grade product cultivated and produced by modern factories. Spirulina is rich in active potassium, sodium, calcium, magnesium and other alkaline minerals. Eating it can neutralize and regulate the acidic constitution of human body.
According to the research of pathophysiologists, more than 90% of the body fluids of people who are prone to illness are acidic, so people whose neutral body fluids or body fluids remain weakly alkaline (PH 7.35-7.45) have better health. We need to supplement nutrition every day to maintain the needs of physical and life activities. In order to make food nutrition become the energy needed for life activities, it must be "burned" in the body. The by-products of "combustion" are carbon dioxide and hydrogen ions, in which carbon dioxide can be directly discharged from the lungs, but hydrogen ions combine with oxygen and run into the blood. Healthy people will be excreted from urine soon after the circulation of body fluids, but when the human body loses its balance, these hydrogen ions tend to accumulate in the blood in large quantities, so the human body will present acidic body fluids. At this time, it is necessary to supply a large amount of oxygen to promote the excretion of hydrogen ions in the blood. In the long run, there will be insufficient oxygen supply in the human body, making the plasma acidic. People with this acidic constitution will feel tired, listless and sick as long as they work a little.
The main reasons for the acidity of body fluids are unreasonable diet and excessive fatigue. Usually there are many sources of acidic components in the food we eat, such as meat, eggs, fish, oil, polished rice, white flour and other foods. The metabolic products of these foods are the main sources of acidic components in the body. Relatively speaking, the source of alkaline components ingested by human body is less, which leads to the lack of minerals in the body. If sodium, potassium, magnesium and other elements are insufficient, it will easily evolve into acidic body fluids. Therefore, in order to maintain alkaline body fluids, the human body must ingest more mineral elements.
If you take too much mineral photography or take abiotic compound minerals to supplement it, the burden of renal function will often be too heavy. Spirulina growing in alkaline medium is a natural food rich in balanced and bioactive organic compound minerals. Therefore, after eating spirulina, it can not only neutralize the acid produced by eating too much meat and sugar. Using its basic ions has no side effects on human cells, tissues and organs, which is of great help to maintain the acid-base balance in the body and maintain health.
(7) Spirulina and anemia
The incidence of anemia in developing countries is very high, reaching more than 20% in China, especially in rural areas. The general symptoms of anemia are pallor, fatigue, dizziness, tinnitus, inattention, rapid breathing and heartbeat. One of the main causes of anemia is genetic defect; The other is nutritional anemia, in which iron deficiency anemia is the most common. Iron deficiency anemia can affect children's intellectual development and reduce immunity, gastrointestinal function and muscle function; It not only affects the health of pregnant women, but also causes iron deficiency and dysplasia of the fetus; For adolescents, it also has a great influence. A survey shows that many primary and middle school students are inattentive and hyperactive in class, and one of the reasons for this performance is anemia. There are many reasons for anemia, such as insufficient iron supply in food, problems in iron absorption, and lack of vitamin B 12 and folic acid. In addition, when the demand for nutrition in life increases (such as infants, teenagers and pregnant women), anemia will also be caused by insufficient supply.
Spirulina is rich in iron, vitamin B 12 and chlorophyll, in which iron is an important raw material for synthesizing hemoglobin and an indispensable element for many iron-containing enzymes. When the body is deficient, it will cause iron deficiency anemia and low physique, while in spirulina, the iron content reaches100-160mg/100g (see table). Vitamin B 12 is an important coenzyme and catalyst in hemoglobin synthesis. If the body lacks coenzyme vitamin B 12, it will lead to megaloblastic anemia. The structure of chlorophyll is almost the same as that of hemoglobin, but the central atom is different (the central atom of chlorophyll is magnesium and the central atom of hemoglobin is iron), which can not only provide raw materials for hemoglobin synthesis, but also stimulate hematopoietic organs and enhance hematopoietic function. According to relevant experiments, Spirulina can obviously increase the iron content in the tissues of rats with iron deficiency anemia, and the utilization rate of iron is close to that of standard ferrous sulfate, and the curative effect is not comparable to that of ordinary synthetic iron agents. Experts also studied the utilization rate of iron in spiral irrigation by the method of hemoglobin depletion and replenishment, and found that the regeneration efficiency of spirulina for hemoglobin was similar to that of eggs. In addition, other documents reported that the polysaccharide in spirulina can enhance the proliferation of mouse bone marrow cells and promote the hematopoietic function of bone marrow.
Because spirulina is rich in high-quality protein, vitamins, chlorophyll and minerals, eating spirulina is not simply to supplement iron and promote hematopoietic function, but to supplement various nutrients in a reasonable proportion. In addition, spirulina itself is a natural nutritious food without any side effects, so it is of great significance to use spirulina as a food to prevent iron deficiency anemia.
(8) Spirulina and hypertension
The upper limit of normal blood pressure is systolic blood pressure 140mm Hg, diastolic blood pressure 90mm Hg, and blood pressure exceeding 160/95 is hypertension.
The main factors affecting blood pressure are cardiac output and peripheral resistance of arterial blood vessels. With the increase of age, especially in the old age, due to the lack of choline, the kidney is easily damaged, so arteriosclerosis gradually occurs, intima thickening and lipid plaque formation appear in the arterial wall to varying degrees, intima rupture and calcification appear in severe cases, and villous fiber breakage and fibrosis appear in the middle layer of the artery to varying degrees. The more severe the arteriosclerosis is, the more obvious the wall elasticity is weakened, or even disappeared. Due to the weakening of arterial elasticity, blood pressure will increase when the heart contracts.
Hypertension patients have high blood pressure, which is easy to cause cardiac insufficiency, angina pectoris and even myocardial infarction. Generally, diuretics are used to lower blood pressure, that is, excessive water in blood is discharged to reduce cardiac output and achieve the purpose of lowering blood pressure. However, diuretics have great side effects. Although it is effective for patients with hypertension, some people, especially the elderly, have low blood potassium and insufficient intake. Once the blood pressure drops too low, it will cause serious ischemia of brain, heart and kidney, and may further cause cerebral thrombosis or myocardial infarction. Therefore, the elderly should be cautious about lowering blood pressure.
Regular consumption of spirulina is very beneficial for lowering blood pressure in the elderly. Although spirulina does not contain choline, biochemistry shows that choline can be synthesized in vivo, serine can produce choline with the help of vitamin B6, and methionine can also be converted into choline. Spirulina [1] contains 3.25% serine and 1.95% methionine. Choline acts on the human body and can lower blood pressure. Spirulina is rich in unsaturated fatty acids, especially γ -linolenic acid, docosaenoic acid and arachidonic acid. It can also reduce blood fat and relieve atherosclerosis, so spirulina has a good effect in reducing blood fat and blood pressure. In addition, if patients with hypertension lack potassium, it will damage the glomerulus and aggravate the condition. The potassium content in spirulina is about ten times that of vegetables, so eating spirulina has obvious effects of supplementing potassium and strengthening kidney.
(9) Spirulina and gastropathy
People in modern society are prone to stomach trouble because of their intense work and irregular daily diet. Under normal circumstances, the duodenal cavity is slightly alkaline, causing pain. According to the data survey, more than 30% of men have excessive gastric acid secretion, which leads to symptoms such as gastric ulcer, duodenal ulcer and gastritis. About 40% of them have indigestion, loss of appetite, anorexia, partial eclipse, unbalanced nutrition and lack of youthful vitality. More than 50% of men have difficulty in gastrointestinal absorption, and are prone to fatigue and aging, gastrointestinal pain or discomfort, which affects their work or study.
The main cause of stomach trouble is physical stress, which mainly comes from work fatigue, mental tension, bad mood, lack of sleep, virus infection and so on. When the body is stressed, it consumes a lot of energy, especially protein. Protein is stored in many organs of human body, such as liver, lymph glands and thymus. If the pressure is too high, it will not only consume the stored protein, but also shunt the protein in the stomach wall and intestinal wall, which will make the gastrointestinal wall thinner, leading to atrophy of mucous glands in the stomach wall and decreased secretion. Therefore, when food enters the stomach, gastric acid secretion will directly stimulate the stomach wall and feel stomachache.
People usually use drugs to neutralize stomach acid when treating stomach diseases and duodenal ulcers. The long-term neutralization of gastric acid affects the absorption of protein and minerals, leading to malnutrition, further disorder of gastrointestinal function and vicious circle. If you stop taking the medicine, your condition will be unstable again. Therefore, the normal preventive measures are: first, eat more digestible food to inhibit the increase of gastric acid; Secondly, eat more alkaline foods that can neutralize stomach acid; Third, take enough protein, minerals and vitamins to maintain a nutritional balance.
Spirulina itself grows in an alkaline environment and contains the most abundant alkaline elements such as potassium, sodium, calcium and magnesium. It is the best alkaline food, which can neutralize gastric acid and solve the nourishing problem of gastrointestinal nutrition. After eating spirulina, spirulina can be quickly decomposed into fine particles and attached to the gastric and duodenal mucosa to form a protective film, thus promoting the regeneration of gastric mucosa, repairing damaged gastrointestinal mucosa, regulating excessive gastric acid and making the stomach feel comfortable. Long-term consumption can make the gastrointestinal surface smooth, elastic and youthful. A large number of clinical trials at home and abroad show that eating spirulina is effective in treating stomach diseases. A hospital in Japan once tried spirulina treatment for patients with gastric ulcer and gastritis, and let patients eat 4 grams of spirulina every day. After three weeks, the stomachache and burning sensation of most patients were greatly reduced. It can be said that spirulina is an ideal food for patients with gastrointestinal diseases.
(X) Spirulina and cancer
Cancer has always been called a "terminal disease", so that many people have reached the level of "talking about cancer discoloration". There is no denying that cancer has claimed countless lives.
Spirulina contains a variety of physiologically active substances with anticancer effects, such as phycocyanin, β-carotene, seaweed polysaccharide and so on. Although it can't kill cancer cells directly, as an antioxidant, it can effectively remove free radicals produced in the metabolic process of the body, stimulate the immune activity of the body, and thus inhibit the synthesis of DNA and protein of cancer cells.
Phycocyanin: Phycocyanin is a special photosynthetic pigment protein, which only exists in cyanobacteria, red algae and cryptoalgae. This pigment is not only nutritious, but also has obvious anti-cancer effect. A special issue of the United States reported that the survival rate of mice in the oral phycocyanin group after five weeks was 90%, while that in the control group was only 25%. After eight weeks, all the control group died, while 25% of the treatment group survived. The results also showed that the lymphocyte activity in the treatment group was higher than that in the control group and also higher than that in the routine group. Phycocyanin can stimulate the immune system and improve disease resistance.
Beta-carotene: Spirulina is rich in beta-carotene. Natural beta-carotene is easier to absorb and assimilate than synthetic beta-carotene, and has higher antioxidant effect. Harvard University fed 20 hamsters pretreated with oral cancer with β -carotene from spirulina. As a result, none of them developed oral cancer, while all 20 control hamsters developed oral cancer.
Algae polysaccharide: Algae polysaccharide can promote the synthesis of protein, enhance immune function and inhibit or kill tumor cells. It is reported that spirulina contains a glycoprotein, which can be treated with α -amylase to obtain an anti-tumor product. Studies by the Institute of Hydrobiology, Chinese Academy of Sciences show that spirulina has anti-mouse sarcoma-180 activity, and a mixture of lipid substances has been found in these algae, which has the same result. In addition, the role of glycoprotein in this respect has also been reported.
A large number of clinical trials at home and abroad show that spirulina is very effective for patients with weak cancer and those with leukopenia and low immune function after radiotherapy and chemotherapy. Compared with similar tumor adjuvant drugs, its advantages are: maintaining the stability of white blood cells, red blood cells, platelets and hemoglobin during radiotherapy and chemotherapy; Improve the clinical adverse reactions caused by radiotherapy and chemotherapy; Balanced supplement of various essential nutrients for human body; Release the toxic inhibition of radiation on the proliferation of bone marrow cells; Effectively reduce the damage of chemical drugs to the immune system of the body. In addition, Spirulina can also improve dizziness, fatigue, anorexia, insomnia, dry mouth, nausea and other symptoms caused by radiotherapy and chemotherapy, and it is safe, non-toxic, convenient to eat and more acceptable to patients. Natural nutritious food like this integrates a variety of effective anticancer substances and can play a synergistic role in human body, so spirulina is an ideal anticancer food.
(1 1) Spirulina and Children's Development
Children and adolescents are in the period of growth and development, with heavy learning tasks and great physical consumption. If the diet nutrition is unreasonable, it is prone to malnutrition, inattention, memory loss, vision loss and other phenomena. Some nutritional deficiencies or disorders can also lead to obesity, and children who are too partial to food, picky eaters and anorexia will also be excessively thin.
Spirulina is rich and balanced in nutrition, which is beneficial to children's development. It can also make teenagers' muscles strong, keep fit, maintain vigorous metabolism, promote the activity of various enzymes in the body and make nerve cells develop normally. Professor Yu Ruomu, a famous nutritionist, said: "Spirulina can make thin children strong and fat children lose weight." A hospital has done experiments on children below 12, and let these children eat 3 grams of spirulina every day. The results after 63 days showed that the weight of these children increased by 2. 14 kg, while the children who did not eat spirulina only increased by 0. 12 kg. In a village in Togo, Africa, due to the obvious lack of protein and vitamins in people's daily diet in this area, children are stunted, not only thin, but also often get sick and even die. French biologist Fox made some children eat spirulina. After a while, it was determined that these children were taller and stronger than those who didn't eat spirulina, especially some thin children, who became stronger after eating spirulina. In Japan, because the government advocates adding 75% spirulina dry powder to ordinary food as an inter-class meal for school students, students' physique and intelligence have been significantly improved. It can be seen that spirulina is of great help to children's development.
