Soy Phytoestrogen

Soy phytoestrogens are thought to work by binding to estrogen receptors in the body. This can either mimic the effects of estrogen or block its action, depending on the tissue and the person. Some of the potential health benefits of soy phytoestrogens include: - Reducing the risk of breast cancer - Reducing the risk of heart disease - Reducing the risk of osteoporosis - Relieving menopausal symptoms

Estrogen receptors

Estrogen receptors are proteins that bind to the hormone estrogen and regulate the expression of genes.

Thyroid Hormone Synthesis

Thyroid hormone synthesis is the process by which the thyroid gland produces the hormones thyroxine (T4) and triiodothyronine (T3).

Soy Phytoestrogens: Debunking the Myths

Bladder weakness and leaks can be miserable - but the good news is, that if you aren't ready or don't want to take medication, Soy can help to alleviate symptoms.

However, there is a lot of misinformation about soy on social media and beyond - and usually the concern is around estrogen and risk of cancer. So let us help clarify and correct some of those myths with this deep dive into Soy Phytoestrogen.

Understanding Soy and Estrogen

Soy, derived from soybeans, is a versatile and nutritious legume that has been consumed for centuries. It is commonly found in various foods and products such as tofu, tempeh, soy milk, edamame, and soy protein isolate. Soy contains compounds called isoflavones, specifically genistein and daidzein, which are classified as phytoestrogens. Phytoestrogens are plant-derived compounds that possess a chemical structure similar to estrogen, the primary female sex hormone.

Due to their structural similarity, phytoestrogens can bind to estrogen receptors in the body, mimicking the effects of estrogen to some extent. This characteristic has raised concerns among women, especially regarding potential hormonal imbalances and increased cancer risks.

How does Soy help with bladder issues such as overactive bladder and leaks?

Soy intake may offer potential benefits for individuals experiencing bladder weakness and overactive bladder conditions. Soy-based foods, such as tofu and edamame, contain high levels of plant-based protein and isoflavones, which possess anti-inflammatory and antioxidant properties. These properties may help reduce inflammation in the bladder and support overall urinary tract health.

Additionally, the phytoestrogens found in soy have been associated with improved muscle tone and strength in the pelvic floor muscles, which play a crucial role in bladder control.

How does Soy work to improve bladder function?

  1. Anti-inflammatory Effects: Soy contains compounds with anti-inflammatory properties, such as isoflavones and other phytochemicals. Inflammation in the bladder can contribute to bladder weakness and overactive bladder symptoms. By reducing inflammation, soy may help alleviate discomfort and promote a healthier bladder.

  2. Antioxidant Protection: Soy is rich in antioxidants, which help combat oxidative stress and protect cells from damage. Oxidative stress can negatively impact bladder health, leading to inflammation and dysfunction. By consuming soy, you provide your body with a source of antioxidants that may help protect the bladder from oxidative damage and support its proper functioning.

  3. Hormonal Balance: Phytoestrogens found in soy, such as genistein and daidzein, possess weak estrogenic activity. These compounds can bind to estrogen receptors in the body, potentially influencing hormonal balance. Hormonal fluctuations can affect bladder health, and maintaining hormonal balance may help reduce bladder weakness symptoms.

  4. Pelvic Floor Muscle Support: The pelvic floor muscles play a crucial role in maintaining bladder control. Weakness or dysfunction in these muscles can contribute to bladder weakness and overactive bladder symptoms. Some studies suggest that soy isoflavones may have positive effects on muscle tone and strength, including the pelvic floor muscles. By supporting the pelvic floor muscles, soy consumption may enhance bladder control and alleviate symptoms.

Is there really a link between Soy and Cancer?

One specific concern associated with soy consumption is its purported link to cancer, particularly breast cancer. However, numerous studies and research have been conducted to examine this association, providing valuable insights into the matter.

Breast Cancer

The evidence from various studies does not support the notion that moderate soy consumption increases the risk of breast cancer. In fact, studies indicate that soy intake may even have a protective effect against breast cancer development. According to a meta-analysis of 35 studies published in the Journal of the National Cancer Institute, soy intake was associated with a modest reduction in breast cancer risk. The study suggests that consuming around 10 milligrams of soy isoflavones per day may provide protective benefits against breast cancer.

Endometrial Cancer

Another concern is the potential impact of soy on endometrial cancer. However, current evidence suggests that soy consumption does not increase the risk of endometrial cancer. A comprehensive analysis of 15 studies published in the International Journal of Cancer found no significant association between soy intake and endometrial cancer risk in women.

Ovarian Cancer

Additionally, studies exploring the relationship between soy intake and ovarian cancer risk have shown no consistent evidence of increased risk. A systematic review and meta-analysis of 11 studies published in the International Journal of Gynecological Cancer concluded that soy intake was not significantly associated with ovarian cancer risk.

Prostate Cancer

While much of the concern regarding soy and cancer centres around women's health, it is worth mentioning that soy consumption has also been studied in relation to prostate cancer in men. Findings from these studies indicate that soy intake may have a protective effect against prostate cancer development. A meta-analysis published in Nutrients analyzed 30 studies and found that soy isoflavone intake was associated with a reduced risk of prostate cancer.

The Pros and Cons

Let's take a look at the positive impact of including Soy in your diet - for your whole body health, not just your bladder!

Heart Health: Soy contains high levels of polyunsaturated fats, which are considered heart-healthy fats. Consuming soy as part of a balanced diet may help lower cholesterol levels, reduce the risk of cardiovascular diseases, and promote heart health.

Menopausal Symptoms: Phytoestrogens found in soy may alleviate menopausal symptoms, including hot flashes and night sweats. Some women report a reduction in these symptoms after incorporating soy products into their diet.

Bone Health: Soy contains isoflavones that possess weak estrogenic activity, which may help support bone health and reduce the risk of osteoporosis. Studies suggest that soy intake may contribute to increased bone mineral density and improved bone health.

Plant-Based Protein Source: Soy is an excellent plant-based protein source, making it a suitable alternative for individuals following vegetarian or vegan diets. Incorporating soy-based products into your diet can help meet your protein requirements and support muscle health.

Now we know the positives - what are the concerns? Let's take a look:

Allergies: Soy is one of the top eight allergens, and some individuals may have soy allergies or sensitivities. If you experience symptoms such as hives, swelling, or difficulty breathing after consuming soy products, it's important to seek medical advice and consider avoiding soy-based foods.

Thyroid Function: Soy contains substances known as goitrogens that can interfere with thyroid hormone synthesis. However, the impact of soy on thyroid function appears to be minimal unless consumed in very large quantities. If you have an underactive thyroid or are taking thyroid medication, it is advisable to discuss soy consumption with your healthcare provider.

Digestive Issues: Some individuals may experience digestive discomfort, such as bloating or gas, when consuming soy products. If you notice these symptoms, it may be helpful to moderate your intake or try different soy-based alternatives.

How to get more Soy into your diet

If you decide to include soy in your diet, it's important to do so in moderation and as part of a well-balanced eating plan. Here are a few tips to help you incorporate soy into your diet wisely:

  1. Choose Whole Soy Foods: Opt for whole soy foods like tofu, tempeh, and edamame, as they provide a range of nutrients and are less processed than some soy-based products.

  2. Read Food Labels: When purchasing processed foods that contain soy, read the labels to ensure they contain non-GMO soy and minimal additives or preservatives.

  3. Diversify Your Protein Sources: While soy is a valuable source of plant-based protein, it's important to incorporate a variety of protein sources into your diet. Combine soy with other protein-rich foods like legumes, nuts, seeds, and whole grains.

  4. Use a soy-based supplement, such as Jude's Bladder Strength Supplement to gain the best soybean extract in an easily consumable and effective way.

It's important to be mindful of individual allergies, sensitivities, and the impact of soy on thyroid function. By making informed choices and consulting healthcare professionals when necessary, you can confidently enjoy the advantages of soy as part of a balanced and diverse diet.
