Previous reports made from a lot of scientists in both foundations and publications of cancer have stressed the importance of soy to reduce breast cancer. Meanwhile there has been plenty of research to contradict these claims and completely oppose them. Researchers at the Memorial Sloan Kettering Cancer Center in New York studying invasive breast cancer are warning women that adding soy to your diet will speed up the rate at which breast cancer cells spread.
The Chinese have not been eaten unfermented soybeans as they have to other legumes like the lentils because the soybean has a large quantities of natural toxins or “antinutrients”. First among them are potent enzyme inhibitors that block the action of trypsin and other enzymes needed for protein digestion.
These inhibitors are large, tightly folded proteins that are not completely deactivated during ordinary cooking. They can produce serious gastric distress, reduced protein digestion and chronic deficiencies in amino acid uptake. In test animals, diets high in trypsin inhibitors cause enlargement and pathological conditions of the pancreas, including cancer.
Accelerates The Progression of Breast Cancer
Researchers at the Memorial Sloan Kettering Cancer Center have made a comparison with tumor tissues from before and after a 30-day regimen of consuming a soy supplement while a control group took a placebo. They found changes in the expressions of certain genes, that are known to promote cell growth, in those women taking the soy supplement.
The findings have come to decision them to conclude the soy protein needs to potentially accelerate the progression of the disease. The study states: ‘These data raise concern that soy may exert a stimulating effect on breast cancer in a sub set of women.’
Thousands of women are now taking soy and think that it helps to protect them with breast cancer. Yet, in 1996, researchers have found that women that take soy protein isolate had an large incidence of epithelial hyperplasia, a condition that makes the malignancies. A year later, dietary genistein was found to stimulate breast cells to enter the cell cycle – a discovery that led the study authors to conclude that women should not consume soy products to prevent breast cancer.
Vegans and Vegetarians At Risk
The women that have high genistein levels were interviewed and some of them said that they have experienced changes in a specified set of genes that are known to affect breast cancer cell growth, death, or some aspect of breast cancer pathology, Dr. Jacqueline Bromberg, co-author of the study said.
The changes have been seen in women that have consumed around 51.6 grams of soy – the equivalent of about four cups of soy milk a day.
The researchers made a decision that people who eat soy regularly could ‘reasonably consume that amount’ through the course of a day, particularly vegetarians and those who do not eat dairy products.
They made a warning to those that are living in Asian countries that can be especially at risk, due to the high levels of tofu and soy in traditional diets.
Dr Bromberg, said: ‘We’re not talking about 20 times more soy.
‘We’re talking about something that a person could eat.’
A 1998 survey has found that the average daily amount of soy protein that has been consumed in Japan has been about eight grams for men and seven for women – less than two teaspoons. Americans are consuming amounts far exceeding this quantity.
Any ingredient listed to be soybean or soy on any product ingredient list has a 93% chance of being GMO if it is not listed as organic. But even organic soy cannot be trusted. Soy is very problematic crop. Non-organic sources of soy in many agricultural practices are being passed off as organic.
In 2011, the USDA has revealed a plot to import fraudulent organic certificates produced by an uncertified supplier in China. The Chinese firm used the counterfeit certificate to represent non-organic crops, including soybeans, millet and buckwheat, as certified organic. These types of things are happening every year and only a fraction are being discovered. Even domestically sourced organic soybean crops are now being investigated for having GMO origins. Organic soy also does not change the toxicity of unfermented sources so abundant in the food supply.
