Earlier reports by different scientists in cancer foundations and publications have pointed to the importance of soy to reduce breast cancer. In the meantime, there has been mounting evidence to oppose them. A team of researchers at the Memorial Sloan Kettering Cancer Center in New York are warning women that consuming soy will accelerate the rate at which breast cancer cells spread.
The Chinese didn’t consume unfermented soybeans as they did other legumes like lentils because soybeans contain large quantities of antinutrients. First among them are powerful enzyme inhibitors which block the action of trypsin and enzymes required for protein digestion.
These inhibitors are tightly folded proteins which aren`t complicated deactivated during cooking. They can produce chronic deficiencies in amino acid uptake, reduced protein digestion, and gastric distress. In test animals, diets highs in trypsin inhibitors may cause both enlargement and pathological conditions of the pancreas.
Accelerates The Progression of Breast Cancer
The team of researchers at the Memorial Sloan Kettering Cancer Center compared tumor tissues from before and after a 30-day regimen of taking a soy supplement while the control group took a placebo. Changes in the expressions of certain genes in the women taking soy supplements were found, which are known to promote cell growth.
These findings led them to conclude that soy protein could potentially speed up the progression of the disease. According to the study, ‘These data raise concern that soy may exert a stimulating effect on breast cancer in a subset of women.’
Countless women are now eating soy believing that it protects them against breast cancer. But, a 1996 research has found that women consuming soy protein isolate had an increased incidence of epithelial hyperplasia, a condition which presages malignancies.
Thousands of women are now consuming soy in the belief that it protects them against breast cancer. Yet, in 1996, researchers found that women consuming soy protein isolate had an increased incidence of epithelial hyperplasia, a condition that presages 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.
“It’s a myth that soy prevents breast cancer,” says Kaayla T. Daniel, PhD, author of The Whole Soy Story: The Dark Side of America’s Favorite Health Food. “Numerous studies show that soy can cause, contribute to or even accelerate the growth of cancer.”
Vegans and Vegetarians At Risk
Of the women with high genistein levels, a couple of them experienced changes in genes which are known to affect breast cancer cells, Dr. Jacqueline Bromberg, co-author of the study said. The changes were seen in those who consumed about 51.6 grams of soy – the equivalent of about 4 cups of soy milk daily.
As concluded by the researchers, those who consume soy regularly could ‘reasonably consume that amount’ through the course of a day, especially vegetarians and those who do not eat dairy products.
Dr. Bromberg, said: ‘We’re not talking about 20 times more soy.
‘We’re talking about something that a person could eat.’
