Products with soy increase the risk of cancer

O soy In general, it is a healthy alternative to protein for those who prefer not to eat meat. However, the results of the investigations The effects of soy on reducing the risk of cancer are diverse, especially in cases of breast cancer.

According to the American NGO against breast cancer Breastcancer, soy products They have estrogen-like properties and therefore concerns have increased A potential increase in the risk of breast cancer due to the consumption of these. Thus, there is a certain concern that high levels of estrogen help cancer cells to grow and spread, even if this is controversial.

In particular, they are the ones isoflavones The soy component that has properties similar to estrogen. According to Breastcancer, it is not clear whether soy isoflavones affect breast cancer, especially breast cancer hormone receptor positive.

Isoflavones can affect the ability of hormone therapy to do their work if the two molecules compete to enter the same estrogen receptors. If isoflavones send a signal of oestrogen to the receptor more weakly compared to tamoxifen (and the estrogens of the body), isoflavones may be able to reduce the growth of estrogen-dependent breast cells. However, if isoflavones send a stronger estrogen signal to breast cells than tamoxifen, a problem arises, "he adds.

Even the panoramamany doctors It is recommended that women receive hormonal therapy or they are diagnosed cancer Positive estrogen receptors for mum avoid supplements of soybeans, as they contain high concentrations of isoflavones. However, consider moderate amounts of soy foods to be eaten as part of a balanced diet.

In an interview with Infosalus, nutritionist specializing in Oncology at the IOB Institute of Oncology, Jordina Casademunt, points out that one of the most frequent questions about hormonal breast cancer is sensitive if soy can be consumed, since this legume is rich in isoflavones , phytoestrogens that have a structure similar to endogenous estrogen but a weaker activity than estrogen produced by the body.

In some animal studies it has been shown that the components of soy (xenistein, a type of isoflavone) can increase the estrogen receptor (ER +) and promote the growth of the tumor. But, on the other hand, it was seen that mice metabolize phytoestrogens like genistein in a different way. It was observed that gesnistein binds more easily to a type of estrogen receptor that inhibits tumor growth (ER-beta), "explains nutrition experts for cancer patients.

It has also been seen that it depends on our intestinal health (if we have the bacteria that produce equol), we can ferment the soy compounds in biologically active forms that are beneficial for our health. "The latest studies show that depending on your intestinal microbial you can metabolize this soybean well and that it is healthy for you, it protects your breast cancer, or you do not have the ability to make these metabolites healthy and its consumption is not recommended." .

The American recommendations for the consumption of soy in breast cancer point to small but daily doses. "It is not a problem food in itself, nor is it a food in our area, so consumption is once or twice a week affects little and has no impact.

In particular, it cites British Cancer Research and the American Cancer Society, which indicate that research has shown that moderate consumption of soy foods seems to be safe. Instead, it is recommended to avoid concentrated soy products such as supplements, foods made with soy protein insulator.

The recommendations that are seen are safe for health are: 1-2 servings per day of soy products such as tofu, edamame, tempeh. Although the best forms (or those I would recommend are the fermented forms: miso, tempeh, tamari), "he emphasizes.

Beyond the dream

For a sick woman or when it comes to preventing hormone-dependent breast cancer, it also highlights that physical exercise has the most positive impact because it is found in fat tissue where estrogen accumulates. "The fact of exercising and favoring a healthy weight is more interesting than knowing if soy is eaten or not. The impact that weight has on the prevention of breast cancer is greater," he insists.

In your opinion, what is really important when considering breast cancer is diet and overall weight. "Having an adequate weight (avoiding overweight), exercise, consuming vegetables and fruits daily, and reducing red meat consumption can reduce the risk of breast cancer by 22%, given that the metabolic syndrome is associated with a higher risk of breast cancer and other types of cancer, "says the IOB Institute of Oncology specialist.
