Is There a Link Between Soy and Cancer?

Soy is a staple food for vegans and vegetarians. You don’t need to be a vegetarian to enjoy soy; however, many people stopped consuming soy because of the negative press it’s received in recent years. The manufacture of soy-based food increased significantly in the last decade, but now most people are eating far less or have given it up altogether. Why? Isn’t soy good for you? Many articles say that soy causes cancer. This is what most people think nowadays. Women especially are afraid of eating soy products because of the link to breast cancer. Let’s look at the facts.

Soy Acts Like Estrogen

This is partly true. Soy contains compounds knows as isoflavones. The compounds are similar to estrogen chemically. They also behave like estrogen in the body; however, they are far less potent than estrogen found in the body. The basis of some studies is that more estrogen equals higher risk of breast cancer, leaving one to conclude that, if isoflavones behave like estrogen, then that will also put one at higher risk for breast cancer. This, however, is not the case.

This is where it gets a little tricky. Isoflavones can also have anti-estrogen properties, and this is a good thing. When estrogen locks into an estrogen receptor, it sends a flood of signals that can trigger estrogen-receptor-positive breast tumor growth. Isoflavones can prevent natural estrogen from binding to estrogen receptors. The anti-inflammatory and antioxidant properties of isoflavones can help reduce and even prevent cancer growth.

Cancer Research On Soy

Most available studies are either poorly designed or are inconclusive. Tests performed on rodents typically utilize soy protein isolate, which to this day has not been proven to be harmful to humans. Additionally, studies often feature unusually high amounts of soy injected into rodents; these high levels of soy are not truly representative of how much soy humans consume. Lastly, rodents process soy differently than humans do, making those studies completely irrelevant.

Soy products are a customary staple of Asian eating and vegan/vegetarian diets.  But the advantages of soy they have turned out to be prevalent lately among non-Asians, particularly postmenopausal ladies. There are numerous bioactive soybean segments that may add to the estimated medical advantages of soy however most consideration has concentrated on the isoflavones, which have both hormonal and nonhormonal properties.

In any case, notwithstanding the conceivable advantages concerns have been communicated that soy might be contraindicated for a few subsets of the populace. One concern is that soy may unfavorably influence thyroid capacity and meddle with the retention of engineered thyroid hormone. Subsequently, the reason for this audit is to assess the important writing and give the clinician direction to informing their patients about the impacts with respect to soy on thyroid capacity.

Altogether, 14 trials (thyroid capacity was not the essential wellbeing result in any trial) were recognized in which the impacts of soy sustenances or isoflavones on no less than one measure of thyroid capacity was evaluated in apparently solid subjects; eight included ladies just, four included men, and two both men and ladies. With just a single special case, either no impacts or just exceptionally unobtrusive changes were noted in these trials. Along these lines, all things considered the discoveries give little confirmation that in euthyroid, iodine-packed people, soy products, or isoflavones antagonistically influence thyroid capacity.

Conversely, some proof proposes that soy products, by hindering retention, may expand the measurements of thyroid hormone required by hypothyroid patients. Be that as it may, hypothyroid grown-ups require not dodge soy products. What’s more, there remains a hypothetical concern in light of in vitro and creature information that in people with traded off thyroid capacity as well as whose iodine admission is minimal soy products may expand danger of creating clinical hypothyroidism. Subsequently, it is vital for soy sustenance purchasers to ensure their admission of iodine is sufficient.


All Thing In Moderation – Including Soy

Like most other major crops, most soy available today is genetically modified. Only consume soy that is non-GMO. Food should not be genetically modified. Modified food will cause disease. Man-made chemicals in food and genetically engineered foods are not good for the human body; this is just logical. Also, remember to eat whole soy. This is a great general rule for all foods but for soy especially. Many soy companies spend a lot of money trying to make soy foods taste more like meat, but what this really means for you is more added chemicals, colorants and preservatives. Stick to unprocessed, non-GMO, whole soy such as tofu, tempeh, edamame and miso.
