The efficacy and function of soy isoflavones

Soy isoflavones are flavonoids, a type of secondary metabolite formed during soybean growth, and are a bioactive substance. Due to being extracted from plants and having a similar structure to estrogen, soy isoflavones are also known as phytoestrogens. The estrogenic effects of soy isoflavones affect hormone secretion, metabolic biological activity, protein synthesis, and growth factor activity, making them natural cancer chemopreventive agents.Therefore, they have the effects of beauty, improving menstrual disorders, and preventing osteoporosis.

Soy isoflavones are a type of phytochemical, belonging to the flavonoid family of plants. They are mainly derived from the pods and legumes of leguminous plants, and their content in soybeans is relatively high, ranging from 0.1% to 0.5%. It mainly refers to compounds with 3-benzopyranone as the parent nucleus. There are a total of 12 naturally occurring soy isoflavones in soybeans, which can be divided into three categories: daidzin groups, genistein groups, and genistein groups. Each type exists in four forms: free type, glucoside type, acetyl glucoside type, and malonyl glucoside type. Free type aglycons account for 2% -3% of the total, including genistein, daidzein, and genistein. Glycosides in combination account for 97% -98% of the total, mainly in the form of Genistin and Daidzin, as well as 6 '' - O-malonylGenistin and 6 '' - O-malonyldaidzin, accounting for about 95% of the total. The planting environment, processing methods, genetic factors, and other factors have a certain impact on the content and composition of soy isoflavones, manifested as differences in the total amount and proportion of each component of isoflavones in different soybean varieties.

Nutritional benefits：
1. Beauty and skincare
Soy isoflavones can make women's skin smoother, more delicate, and full of elasticity, especially for middle-aged women who take soy isoflavones in moderation. They can also delay aging and have a beauty and skincare effect.
2. Improve menstrual irregularities
Soy isoflavones can improve symptoms of menstrual disorders. Some women with menstrual disorders have abnormal estrogen secretion in their bodies. Supplementing with soy isoflavones can regulate the internal environment and improve symptoms of menstrual disorders.
3. Preventing osteoporosis
Some postmenopausal women may experience symptoms of osteoporosis, as the decrease in estrogen levels in the body can lead to a reduction in bone mass. Supplementing soy isoflavones can promote calcium absorption and also alleviate osteoporosis.
nutritive value
Soy isoflavones are widely present in more than 300 plants such as beans, grains, fruits, and vegetables. In addition to soybeans and their products, they are relatively abundant in daily diets such as wheat, black rice, beans, onions, apples, pomegranates, ginkgo biloba, sunflower seeds, and orange juice. In every 100 grams of soybeans, there are 128 milligrams of soy isoflavones, 9.65 milligrams in soy milk, and 27.74 milligrams in tofu, making soybeans a high-quality source of isoflavones.
Soy isoflavones have the effects of delaying menopause, regulating menopausal syndrome, improving menstrual discomfort, and regulating endocrine function. They are particularly effective in treating conditions such as hot flashes, sweating, headaches, dizziness, palpitations, insomnia, depression, and limb numbness.
