What is the verdict on Soy in your diet?

There is much controversy on soy products. The following is some of the research from some experts on the risk factors. And remember that moderation is always a good key to a healthy diet.

Back to basics- peas carrots and parsnips.

There is a lot of research on soy and breast cancer risk but most of the studies have come from laboratory animals. According to an article on soy and breast cancer risk from the American Cancer Society, the experts feel that we may be putting a stop to consuming soy too soon.

As with any kind of moderation in eating, you may already know that eating too much fat, eating too much red meat, or being obese seems to be  connected to cancer in our bodies, therefore you may have to decide where it is that you draw the line on soy.


According to Dr. McCullough in his editorial from: The Bottom Line on Soy and Breast Cancer Risk,  the doctor suggests that we need to take a look at the evidence, and most of it does not suggest harm.

In studies with Asian women it has been found that there is a lower risk of breast cancer associated with eating more soy, but U.S. studies have tended to not find any association between how much soy a woman consumes and her risk of breast cancer.

In a recent study with combined data from 14 different epidemiologic studies on the topic of soy found that in Asian countries women who ate the most soy isoflavones had a 24% lower risk of developing breast cancer, while there was no association in Western counties such as the U.S.

While the verdict is still out on consumption of soy we should keep moderation as the key to our dietary consumption.

And with the Asian people, their consumption of soy products are not over-processed soy hot dogs, energy bars, soy protein isolate drinks, veggie burgers and large glasses of soy milk. Asian eat small amounts of tofu; tiny slivers in their soups and most of their soy is fermented not processed.

Begin to read food labels and you may find that soy is in many products that you are unaware of.

Here is a list of where soy is hidden- citric acid, dough conditioner, emulsifiers, glycerol monostearate, hydrolyzed vegetable protein, liquid smoke, vegetable fiber, vegetable gum, Vitamin E, thickening agents, protein concentrate, protein isolate, stabilizers.

The best soy is Organic and Non-GMO soy with no fillers; look for these labels.


You may need to start looking at changing you diet to a more plant based diet where you consume more fresh produce and  whole grain products (without GMOs), and limiting your consumption of all processed foods.

And there is growing evidence between cancer and poor diets in general such as eating deep fried foods, fast food and high carbohydrate diets.

Therefore, changing your diet to one that is more moderate; eating smaller portions, concentrating on losing or maintaining your slim waistline may be the key to living a long, healthy life.

Soy and Breast Cancer:  The good and bad

Because of the fact that soy does act like estrogen in the body, these isoflavones which are similar to estrogen can act like estrogen in the body. and these effects can be good or bad. It has been established that there is a link to estrogen and hormonally sensitive cancers in women. And in breast cancer estrogen can spur on breast tumor growth. And in women who have been diagnosed with Estrogen related cancers, staying away from soy may be needed.

But even through isoflavones may act like estrogen, they also have anti-estrogen properties which means that they can block the more potent natural estrogens- and that is why it is a good and bad news.

And in Epidemiological studies in which large populations of healthy women have reported details about their diets, and were followed for many years, there has been no association between soy and breast cancer, or a protective association – meaning that people who ate more soy had less breast cancer.

Common breast cancer risk factors also include: having children late or not having children and being obese after menopause.
