What foods are high in genistein?

Genistein is a polyphenol compound belonging to the isoflavone class. It is a light yellow crystalline powder with a melting point of 297°C-298°C. It is soluble in DMSO and ethanol, soluble in common organic solvents, almost insoluble in water, and soluble in dilute alkali to appear yellow. Many studies have shown that genistein can relieve inflammation, change intestinal flora, and improve epithelial barrier function in several animal models of intestinal diseases. Genistein is mainly used in the fields of medicine, health products, and cosmetics.

What Foods are High in Genistein?

1. Soybeans and soy products: Soybeans are one of the main sources of genistein, such as soybeans and black beans. Taking soybeans as an example, the genistein content in every 100 grams of soybeans is about 12.8 mg. Common soy products such as tofu, soy milk, dried tofu, and bean skin are also rich in genistein. For example, the genistein content in every 100 grams of tofu is about 1.5 mg.
2. Natto: Natto is made from soybeans fermented by natto bacteria, containing genistein and genistin, which is one of the main active ingredients for anti-cancer.
3. Sophora japonica: The purity of genistein extracted from Sophora japonica can reach more than 99%, which is much higher than other sources.
4. Pueraria root: Pueraria root contains a certain amount of genistein and has many health benefits.
5. Clover: Clover is also one of the sources of genistein and is often used to extract genistein for use in medicine and other fields.
6. Guangdougen: Guangdougen also contains genistein, which has certain medicinal value.​​​​​​​

Genistein Benefits

Effects on the cardiovascular system
Antioxidant: It can effectively inhibit the generation of free radicals and lipid peroxidation, relieve diseases caused by oxidation, lower cholesterol, inhibit the oxidation of low-density lipoprotein cholesterol (LDL), and keep the LDL in the blood at a low level, improve the abnormal peroxidation state in the body caused by high fat, and relieve the peroxidation damage to the body.
Regulate blood lipids: It can upregulate LDL receptors and increase LDL receptor activity, thereby promoting cholesterol clearance, helping to lower blood cholesterol levels and reduce the risk of atherosclerosis.
Inhibit angiogenesis and smooth muscle cell proliferation: It has the effect of inhibiting the proliferation of smooth muscle cells and angiogenesis and inhibiting cell adhesion, thereby reducing the incidence of cardiovascular diseases.

Effects on the nervous system
Promote brain nerve regeneration: It has the effect of promoting brain nerve regeneration and awakening from brain coma, and can protect brain cells when stroke (cerebral hemorrhage) and cerebral infarction (cerebral infarction) occur.
Improve cognitive function: Some studies have found that genistein may help improve cognitive function and help prevent and improve age-related cognitive decline.

Effects on tumors
Inhibit tumor cell growth: It has inhibitory and therapeutic effects on various cancers through mechanisms such as antioxidant effects, inhibition of tyrosine kinase activity, inhibition of topoisomerase activity, estrogen and anti-estrogen-like effects, and reduction of tumor angiogenesis.
Improving the efficacy of anticancer drugs: It has the effects of inducing programmed cell death, improving the efficacy of anticancer drugs, and inhibiting angiogenesis. It is a very potential cancer chemoprevention agent.

Effects on women's health
Relieve menopausal symptoms: It has weak estrogen activity. During menopause, women experience a series of menopausal syndrome symptoms due to ovarian degeneration and reduced estrogen in the body. During menopause, taking a certain amount of genistein can supplement the lack of estrogen in the body and prevent and reduce women's menopausal syndrome, such as reducing symptoms such as hot flashes and headaches.
Prevent osteoporosis: Studies have shown that genistein can increase bone density. For postmenopausal women with osteoporosis, genistein can significantly increase bone density, with an effect similar to estrogen replacement therapy, and can effectively combat hormone-induced osteoporosis.

Other effects
Antibacterial and anti-inflammatory: It has a significant inhibitory effect on some pathogenic bacteria such as Staphylococcus aureus, Escherichia coli, and Acinetobacter baumannii.
Sedative and tranquilizing: It can improve mood swings and has a calming and tranquilizing effect. It can improve symptoms such as insomnia and headache caused by mood swings.
Anti-radiation: It is an effective inhibitor of protein tyrosine kinase activity, and also has antioxidant and estrogen-like effects. It can significantly improve the 30-day survival rate of mice subjected to a whole-body irradiation dose of fatal traumatic brain injury.​​​​​​​
