Soy Safe, Even Protective, for Breast Cancer Survivors

Posted 7 Mar 2017 by

TUESDAY, March 7, 2017 – The pros and cons of soy for breast cancer patients have been debated for years. Now, research involving more than 6,200 breast cancer survivors finds that those who ate the most soy had a lower risk of death from all causes during the nearly 10-year follow-up period. "We didn't find any harmful effects of women diagnosed with breast cancer consuming soy in terms of mortality," said study leader Dr. Fang Fang Zhang. She's an assistant professor of epidemiology at Tufts University's Friedman School of Nutrition Science and Policy in Boston. "Overall, consuming higher levels of soy is associated with a 21 percent reduction in the risk of death compared to women who consumed soy at a lower level," she said. Concerns around soy's "risk/benefit" profile have arisen because the food has estrogen-like compounds called isoflavones. That's important, experts says, ... Read more

Soy May Counter Effects of BPA in Women Undergoing Fertility Treatments

Posted 27 Jan 2016 by

WEDNESDAY, Jan. 27, 2016 – A soy-rich diet may protect women undergoing infertility treatments from the harmful effects of a chemical widely used in food containers, a new study suggests. Bisphenol A (BPA) – which is found in such items as polycarbonate plastic water bottles and can linings – can mimic estrogen, one of the two main sex hormones found in women, and the chemical has been linked to reproductive disorders. More than 96 percent of Americans have BPA in their bodies, according to the U.S. Centers for Disease Control and Prevention. This study included 239 women, aged 18 to 45, who underwent at least one in-vitro fertilization (IVF) cycle between 2007 and 2012. They completed questionnaires about their eating habits (176 consumed soy foods) and their urine was analyzed to measure BPA levels. Among women who did not eat soy foods, those with higher BPA levels had lower rates ... Read more

Soy Supplements Won't Ease Asthma, Study Finds

Posted 26 May 2015 by

TUESDAY, May 26, 2015 – Despite hints from prior research that soy supplements might help asthma patients breathe easier, a major new study finds the nutrient has no beneficial effect on lung function. "This study highlights why it is so important to perform well-designed, placebo-controlled studies when associations are reported between specific nutrients and disease outcomes," study lead author Dr. Lewis Smith, professor of medicine at Northwestern University Feinberg School of Medicine, said in a university news release. The study, published in the May 26 issue of the Journal of the American Medical Association, also highlights the need to focus on overall health – including diet and lifestyle – to manage asthma, rather than on specific approaches such as consuming more soy, he said. "You are what you eat, but that's a whole constellation of foods, not just a single food or a ... Read more

Is Soy a Foe to Women With Breast Cancer?

Posted 4 Sep 2014 by

THURSDAY, Sept. 4, 2014 – Soy protein may increase activity in genes linked to breast cancer growth – at least in certain women who already have the disease, a new study suggests. Experts said the findings, reported in the Sept. 4 Journal of the National Cancer Institute, shouldn't scare women off from eating tofu. But to be safe, the researchers suggest women with breast cancer eat soy foods only in moderation and avoid supplements. And for women who don't have breast cancer? "This study doesn't tell us anything about whether soy raises the risk of developing breast cancer," said researcher Dr. Jacqueline Bromberg, a breast cancer specialist at Memorial Sloan Kettering Cancer Center in New York City. The relationship between soy and breast cancer is complicated. On one hand, in countries where soy is a dietary staple – like Japan – women who eat more of it tend to have a lower ... Read more

Soy Supplements May Not Shield Against Breast Cancer

Posted 3 Feb 2012 by

FRIDAY, Feb. 3 – Soy supplements do not protect women against breast cancer, a new study suggests. The findings are consistent with the results of previous studies that examined the cancer prevention benefits of the dietary supplements, said lead researcher Dr. Seema Khan, a professor of surgery at the Robert H. Lurie Comprehensive Cancer Center of Northwestern University. The study included 98 women who were randomly assigned to receive a mixed soy isoflavones supplement or placebo. Isoflavones are components of soy foods thought to have anti-estrogen activity (estrogen is "fuel" for many breast cancers). After six months, the researchers examined levels of Ki-67 – a protein marker of cancer cell growth – in certain breast cancer cells taken from the women. Overall, there were no differences in Ki-67 levels between women who took the soy supplement and those who took the placebo. ... Read more
