If you haven’t heard yet, soy has been surrounded by conflicting information for quite some time. On one hand, there are those who argue that soy is harmful due to its isoflavones content which can mimic estrogen and cause hormonal issues, as well as the fact that the majority of soy in the United States is genetically modified. On the other hand, it has been considered a health food due to research that suggests it can alleviate menopause symptoms, prevent osteoporosis, and improve cardiovascular health.
The Soy and Breast Cancer Controversy
One of the most debated topics around soy is how it affects breast cancer or how it might be linked to the disease. Studies have found a correlation between soy consumption and the activation of breast cancer genes, while some research found that isoflavones can slow the growth of breast cancer cells in the lab environment. This has left many people confused about whether soy is a risk factor for breast cancer or potentially beneficial in its prevention.
Fortunately, a recent study conducted at Tufts University offers some clarity for certain breast cancer patients, showing that consuming soy can actually increase breast cancer survival rates. In this study, more than 6,000 North American women who were diagnosed with breast cancer had their isoflavone intake recorded, in order to determine if there was any association between soy and their breast cancer outcomes. The results showed that for some women, a higher isoflavone intake correlated with a 21% lower risk of dying from breast cancer. These women generally had tumors without hormone receptors and were not receiving hormone therapy treatment.
Now, what about women who were on hormone therapy for their breast cancer? The study found that isoflavone consumption had a neutral effect on these patients. This is interesting to note, as there is a common belief that soy might interfere with hormone therapy treatments.
Choosing the Right Soy for Your Diet
Given all the available evidence, it is safe to say that, in moderation, soy can be part of a balanced, healthy diet. However, it is essential to choose the right kind of soy to consume, avoiding the overly processed versions like soy-based meat products, energy bars, and other processed soy foods. Instead, opt for simpler versions like tofu, tempeh, or edamame, which are closer to their natural state and carry fewer health risks.
If you want to give your diet an extra health boost, fermented soy foods like miso, tempeh, and natto are great options. These foods contain beneficial bacteria and nutrients that are easier for your body to absorb. And if you are concerned about GMOs, these foods are available in non-GMO versions at health food stores.
In conclusion, by following these guidelines for healthy soy consumption, there is a good chance that some forms of soy can improve your health by promoting a healthier heart, stronger bones, and possibly even reducing your risk of breast cancer. Remember, as with any food or supplement, moderation and quality are key when it comes to reaping the health benefits of soy.
