Soy isoflavones are bioactive substances extracted from non-transgenic soybeans and represent a natural nutritional factor with multiple important physiological activities. However, are there any side effects associated with soy isoflavones? Are there any known side effects of soy isoflavones? It is widely recognized that soy isoflavones are a potent plant estrogen, easily absorbed by the human body, capable of rapidly replenishing nutrients. But are there any side effects of soy isoflavones? In the past, hormone replacement therapy with estrogen has been a lifesaver for many postmenopausal women, even described by numerous doctors and scientists as a panacea for eternal youth.
Over 40% of women in the United States are taking estrogen-containing medications during menopause, with many starting to take them as early as menopause and continuing until they reach their late seventies or eighties.
Women are also told that estrogen, besides its preventive value, is the fountain of youth. It can make the skin smooth and hair thick and strong.
Young women use estrogens to increase their breast size, improve their appearance and treat acne.
However, a recent government-funded scientific trial has found that the benefits of estrogen replacement therapy are outweighed by its risks. It has been proven that taking medication alone for long periods can significantly increase the risk of cardiovascular diseases and breast cancer, as well as increasing the incidence of endometrial cancer by 5 to 7 times.
This report has shocked and angered thousands of women currently taking estrogen.
Subsequently, experts discovered soy isoflavones. Soy isoflavones are plant effective components extracted from natural soybeans. Because they have a very similar molecular structure to estrogen, and can bind to the estrogen receptors in women's bodies, they play a role in regulating estrogen in both directions, hence they are also known as "plant estrogen".
Soy isoflavones have effects such as improving skin quality, alleviating menstrual discomfort, anti-aging, delaying menopause, relieving menopausal discomfort, enhancing sexual quality, preventing osteoporosis, breast cancer, senile dementia, cardiovascular diseases, etc.
Friendly reminder: When choosing soy isoflavones for women, pay attention to selecting natural soy isoflavones, not genetically modified ones. Soy isoflavone extraction materials are soybeans, and the best production area for them is in Heilongjiang province.
When choosing soy isoflavones, consumers can search for more scientific knowledge to understand the functions of these compounds.
The function of soy isoflavones is something that many people may not be aware of. Soy isoflavones' estrogen-like effect can make women's skin smooth, delicate, soft, and full of elasticity, rejuvenating their youthful appearance. It can also regulate estrogen levels, alleviating many symptoms of menopause. Below, we will introduce the functions of soy isoflavones to you.
1. Anti-aging: It can prevent premature ovarian function decline in women, thereby delaying menopause and achieving the effect of delaying aging.
2. Alleviating Menstrual Discomfort: Insufficient estrogen secretion leads to menstrual discomfort. The bidirectional regulatory effect of soy isoflavones can normalize the level of estrogen, thereby improving the condition of menstrual discomfort.
3. Prevention of Osteoporosis: The decrease in estrogen secretion level can easily cause bone mass loss, and timely supplementation with soy isoflavones can effectively prevent the occurrence of osteoporosis.
4. Prevention of Cardiovascular Diseases: To prevent the formation of atherosclerosis and the occurrence of cardiovascular diseases.
5. Breast Cancer Prevention: Bidirectional regulation of estrogen can reduce the activity of estrogen, thereby decreasing the risk of breast cancer in women who have high estrogen levels.
6. Alleviating Postpartum Mental Disorders: After childbirth, progesterone levels decrease, and estrogen levels have not yet recovered, leading to vegetative nervous system disorder and mental disorders. Soy isoflavones can timely replenish this deficiency.
7. Improving Sexual Quality of Life: Soy isoflavones, acting as estrogen-like compounds, nourish the vital organs of women—the vagina. They stimulate the secretion of sexual glands and thicken the vaginal epithelium, enhancing the elasticity of female vaginal muscles. This results in an improvement in sexual quality of life.
Are you aware of the demographics for whom soy isoflavones are appropriate? It's crucial to understand who can use soy isoflavones before opting for a health supplement, as it ensures that they can be used with confidence. Let's delve into the demographics for soy isoflavones now! 1. Middle-aged and elderly women: Women over 30 years old experience a gradual decline in estrogen levels, dropping to 15% of the normal range during menopause. This drop in estrogen can lead to various issues such as insomnia, hair loss, menstrual irregularities, uneven skin tone, declining sexual quality, and osteoporosis. If you are over 30 years old and exhibit symptoms like these, it is very likely that you are lacking estrogen.
2. Population at Risk: Cardiovascular disease patients.
Osteoporosis.
Middle Age of Women.
3. Suitable for Sub-Healthy Populations: For individuals experiencing constipation, it is beneficial for skin care and beauty. For women in puberty who often experience acne on their face, the combined consumption of soy isoflavones and soy oligosaccharides can effectively address these concerns.
To address skin aging and the appearance of pigment spots, it is recommended to take Soy Isoflavone and Collagen together for optimal results.
4. Postoperatively, for female patients who have undergone ovarian or hysterectomy: It is essential for these women to promptly supplement with soy isoflavones as their bodies are no longer able to produce sufficient estrogen.
Warm Reminder: Before and after menopause, due to the decline of ovarian function and the decrease in estrogen levels, various organs and tissues undergo functional adjustments that are not compatible, resulting in a series of symptoms. The supplementation of estrogen can achieve the purpose of preventing and treating such conditions.
Menopausal symptoms in women: hot flashes, sweating, chills, chest tightness, palpitations, shortness of breath, dizziness, and fluctuations in blood pressure.
The individual experiences emotional instability, irritability, agitation, depression, overthinking, insomnia, memory impairment, impaired concentration, and decreased overall judgment.
How to Choose Soy Isoflavone? With the myriad varieties of soy isoflavone available on the market today, the question arises: how do we select them? This has become a headache for many. Let's take a look at how to choose soy isoflavone from the perspective of Mama.com. After understanding this, you will no longer be afraid of "choice anxiety"! 1. Choose Brands: Avoid products that are too cheap.
Many small businesses deceive customers by offering products at very low prices, and it's hard to guarantee the quality of their goods.
Do not choose products that are particularly expensive. Many products impersonate foreign, Hong Kong, and Macau brands, with very high prices and uncertain product quality, as there is no way to claim compensation for quality issues
2. Choose products that have been in production and operation for many years: Long production and operation time proves that the company's products have undergone market selection through survival of the fittest, and only high-quality products can survive in the long run
Products that have not been selected by the market for a long time cannot rely on product quality
3. Choosing products with clear soy isoflavone content on the label: Many companies do not clearly indicate the effective ingredient content on the label because the content is low
The effective ingredients of soy isoflavones need to be taken 50-100mg per day to be effective. Some products are made with soy flour, but the effective ingredients are insufficient and the effect is not good
4. Choose products with anti-counterfeiting labels: Due to the popularity of the products, there are counterfeit goods on the market, and without anti-counterfeiting measures, it is easy to buy counterfeit goods
5. It is best to choose pure natural extraction of soy isoflavones: this will not have too many side effects on female menopause. In addition, choosing soy isoflavones in combination with bee pollen, Polygonatum sibiricum, grape seeds, etc. can achieve greater effects
6. Choose products produced by professional companies: Do not choose small health product companies or OEM products
Foods containing soy isoflavones are a type of flavonoid found mainly in leguminous plants. However, do you know what foods contain soy isoflavones? Next, Mom's Encyclopedia will tell you what foods contain soy isoflavones and whether they are common ingredients that we can usually buy? The food containing soybean isoflavones mainly includes soybean and various soybean products, such as soybean milk, tofu skin, Rolls of dried bean milk creams, tofu, dried tofu, shutter, bean sprouts, etc
Bean Sprouts: Japanese food scientists have confirmed that the content and activity of isoflavones are highest in the newly developed germ of soybeans
Its estrogen is most easily absorbed by the human body
The yellow bean sprouts on the market are usually very long. Their germ energy has been exhausted, while the soy milk we drink is also greatly reduced in its isoflavone activity because the soybean germs have not yet been activated before being ground into powder.
It has been found that the daily intake of 30-50 mg of soy isoflavones can play a protective role.
It is important to note that the various processing methods such as soaking, steaming, frying and baking also significantly affect the content of isoflavones in soy products.
The soaking causes 10% of the isoflavones to be lost in the water.
The loss rate of soy isoflavones after frying was 36%.
Browning resulted in 15% to 21% loss of daidzein.
Dietary fiber may interfere with the absorption of soy isoflavones.
Therefore, if you want to increase the intake of soy isoflavones in your diet, try to choose steaming as a cooking method when preparing soy and its products. Also, avoid consuming them with high-fiber foods in the same meal.
