1, mild reaction: dizziness, tiredness, hard shoulders, diarrhea (soft stools several times a day, no abdominal pain), frequent farting (dozens of times a day) and so on.
2. Severe reactions: headache, swelling, dizziness, fever, eczema, joint pain, sudden rise of blood pressure, breathlessness, vomiting, loss of appetite, etc.
3. The reactions of people with different constitutions are as follows
People with acidic constitution: drowsiness (during the day), dry throat and tongue, frequent urination and frequent farting.
Pale blood: it varies according to the constitution, but there is a slight nosebleed (mostly female)
People with bad liver: I want to vomit, sometimes I will vomit, and my skin will be itchy or rash.
Patients with kidney disease: There is a temporary decrease in protein, and there will be edema on the face.
People with a bad stomach: the chest is stuffy and it is not easy to swallow food.
Gastric ulcer: The bad part will hurt.
Gastroptosis: The stomach always feels sick and wants to vomit.
People with bad intestines: have symptoms of diarrhea, but it varies according to the condition.
Hypertension: dizziness lasts for one to two weeks.
Cirrhosis: Sometimes there will be bloody stool.
Hemorrhoids: Sometimes there will be temporary bleeding.
Pharmacological effects of eating spirulina
1. Anti-radiation damage effect: Oral administration of spirulina before and after radiation irradiation can improve the survival rate of mice.
2. Antibacterial effect: Spirulina platensis has antibacterial effect on gram-positive bacteria. The ethanol extract of Spirulina platensis containing lipids and triterpenoids has the strongest antibacterial activity, and the extract containing sterols also has antibacterial effect, but the effect is weak. Spirulina platensis has no inhibitory effect on gram-negative bacteria.
3. Anti-cancer effect: Spirulina can inhibit the formation of large intestine degeneration crypts induced by short-term single injection and long-term multiple injections of 1 2- dimethylhydrazine in NIH mice and standard deviation rats.
4. Photosensitization: The cultured mouse myeloma cells were treated with phycocyanin (phycocyanin) containing 0.25mg/ml, and then irradiated by 5 14nm laser for 300J/cm2, and the survival rate of cancer cells was only 15%. However, the cell survival rates were 69% and 7 1% by laser irradiation or phycocyanin treatment alone.
5. Effect on immune system: Spirulina polysaccharide can increase the serum hemolysin of mice by 39.5%-98.0%, the phagocytic rate of peritoneal macrophages by 32.5%-5 1.5%, the phagocytic index by 0.9- 1.8 times and the number of T lymphocytes by 46.8%-87.7%. The number of-naphthyl acetate esterase (ANAE) positive lymphocytes increased by 7.3%- 12.8%.
6. Lowering cholesterol: 30 men with high cholesterol and mild hyperlipidemia were divided into two groups. In group A, spirulina was taken 4.2g daily for 8 weeks, and the total serum cholesterol decreased from 6.3mmol/L(244mg/dl) to 6. 1mmol/L(233mg/dl) within 4 weeks, with a decrease of 4.5%. In group B, it stopped after 4 weeks, and the total serum cholesterol decreased, and then returned to the original level. Low-density lipoprotein cholesterol decreased significantly by 6. 1% within 4 weeks, and the serum cholesterol decreased even more in people with high cholesterol level.
7. Protective effect on stomach: Spirulina platensis has obvious protective effect on indomethacin (indomethacin) type and anhydrous ethanol type experimental gastric ulcer models in rats by gavage of 250-500mg/kg; It can reduce the incidence of ulcer model in rats with pyloric ligation and reduce the number of ulcers, and also has a certain inhibitory effect on gastric juice secretion. It can accelerate the healing of gastric ulcer in rats with chronic acetic acid.
Nutritional components of spirulina platensis
Spirulina is characterized by high content of protein, but low content of fat and cellulose, and also contains a wide range of vitamins, which are vitamin B 12 and? -The food with the highest carotene content. In addition, it has the highest absorbable iron content in all foods. At the same time, it is found that it contains algae protein with cancer prevention and treatment functions, as well as other mineral elements and bioactive substances that improve the body's immunity.
Polysaccharide from spirulina platensis is the main form of carbohydrate in spirulina platensis, and its content is as high as14% ~16% of dry weight. The lipids contained in spirulina are almost all important unsaturated fatty acids, and the cholesterol content is very small. The protein content of spirulina dry powder is as high as 60% ~ 72%, which is equivalent to 1.7 times of soybean, 6 times of wheat, 9.3 times of corn, 3.5 times of chicken, 3.5 times of beef, 3.7 times of fish, 7 times of pork, 4.6 times of eggs and 2.9 times of whole milk powder. Spirulina is rich in vitamins B 1, B2, B3, B6, B 12 and vitamin E, etc. It can be said that it completely concentrates all kinds of vitamins that the human body needs most. Spirulina is also a natural treasure house of chlorophyll, which accounts for 1. 1% of algae, 2-3 times that of most terrestrial plants and 10 times that of ordinary vegetables. The main type of chlorophyll contained in spirulina is chlorophyll a, and its molecular structure is very similar to human hemoglobin. It is the direct raw material for human hemoglobin synthesis. Green blood? And the content is as high as 7600mg/kg algae powder. . Spirulina contains all essential amino acids, and the lysine content is as high as 4% ~ 4.8%, which is closest to the recommended standard of FAO compared with animal and plant foods, and its absorption and utilization rate is particularly high for a balanced human body. Spirulina is rich in minerals needed by human body. Calcium, phosphorus, magnesium, iron, sodium, manganese, zinc, potassium and chlorine account for about 9% of the total minerals in algae. Among them, the iron content is 20 times that of general iron-containing foods; The calcium content is 10 times that of milk. These minerals contained in spirulina are all alkali metal elements within the biological range of cells, and have no side effects on human cells, tissues and organs.
