Chlorella can inhibit fat absorption and stimulate the discharge of high-fat food. Clinical research shows that Chlorella can be used to prevent and treat hyperlipidemia and diseases related to hyperlipidemia.
2. Enhance immunity
Chlorella can improve immunity by improving phagocytosis of macrophages, promoting lymphocyte transformation, increasing the number of lymphocytes and enhancing the vitality of natural killer cells, which is mainly related to the efficacy of the following active substances-Chlorella growth factor (CGF): Chlorella growth factor (CGF), also known as Chlorella essence, is a cell active substance.
Toxicological experiments show that CGF is a non-toxic substance, so it has broad prospects as an additive for health care products and functional foods. Chlorella hot water extract (CVE); Chlorella polysaccharide; Heterotrophic Chlorella pyrenoidosa
3. Antioxidant activity
Chlorella glycoprotein has antioxidant effect and can scavenge free radicals in the body. Free radicals are the intermediate products of biochemical reactions in human life activities, including superoxide anion radical (O2) and hydroxyl radical (OH).
4. Anti-tumor
Chlorella can inhibit the mutagenicity and genotoxicity of carcinogens, so it has anti-tumor physiological characteristics.
5, detoxification
Chlorella contains some ingredients for protecting liver and detoxifying. Chlorella can regulate gastrointestinal absorption and promote toxin excretion.
6. Others
According to research, Chlorella also has physiological activities such as anti-radiation, prevention and treatment of various inflammations such as gastric ulcer and ulcerative colitis, and relief of psychological stress and fibromyalgia.

Extended data:
nutritive value
1, protein and amino acids.
Chlorella has a high content of protein, but the nutritional components are different due to different algae species, culture methods and culture media.
Chlorella is rich in protein, with a complete range of amino acids and a ratio close to the standard model, which can fully meet the growth needs of human beings and animals. Chlorella is an excellent single cell protein source and can be used as a nutritional fortifier in food industry. In application, we should pay attention to the coordination with methionine, cystine and threonine, and further improve their nutritional value through the complementarity of amino acids.
2. Polysaccharides
Polysaccharide is a biomacromolecule widely existing in animal cell membrane, plant cell wall and microbial cell wall, and it is one of the four basic substances of life. Chlorella polysaccharide can enhance immune activity. Chlorella, as a nutrient, has been used in the field of medical care because of its special functions.
Chlorella vulgaris was extracted by hot water, deproteinized and precipitated by ethanol to obtain crude glycoprotein, and purified glycoprotein was obtained by Sephadex-75 chromatography. Compared with monosaccharide components, the glycoprotein of Chlorella mainly contains glucose, galactose and rhamnose, and their ratio is 7.3: 1.97: 1. It also contains a small amount of arabinose, xylose and mannose. But the monosaccharide components extracted from different extracts will be different.
3. Fatty acids
The main function of fat is to form a biofilm, provide energy and act as a medium for fat-soluble substances. Epidemiology has proved that eating more unsaturated fatty acids is good for health. Arachidonic acid is the most representative unsaturated fatty acid at present, which can be synthesized from essential fatty acids such as linoleic acid and linolenic acid, and has physiological activities such as lowering blood pressure, reducing blood lipid and resisting atherosclerosis.
The nutritional components of Chlorella pyrenoidosa powder were analyzed. The results showed that the proportion of unsaturated fatty acids in heterotrophic Chlorella pyrenoidosa powder was as high as 77.24%, and the chain length was concentrated in C 16 ~ C 18, in which the contents of essential fatty acids linoleic acid and α -linolenic acid were 47. 17% and 13.03% respectively, which were in other foods.
Therefore, these nutrients of Chlorella make it have special health care functions. In addition, it is worth mentioning that compared with the protein content, Chlorella has a lower fat content and can be used as a high-protein and low-fat food.
