Animal Study: Soy Before Puberty Reduces Breast Cancer Recurrence

How soy plays a role in breast cancer risk and recurrence is one of the most common questions we get asked. A large body of human research suggests eating tofu, soy milk and other soy foods in moderation safe. Now an animal study that may help explain what is seen in human research, shows that eating soy foods when young boosts the immune response against tumors, reducing cancer recurrence.soy_tofu_dreamstime_13994134

The study is being presented at the American Association for Cancer Research (AACR) annual meeting, and is not yet published.

Soy contains compounds called isoflavones that mimic the effect of estrogen. This raised concerns that it would stimulate breast tumors fueled by estrogen and may interfere with anti-estrogen treatment, such as tamoxifen. Early animal studies did find a link between isoflavones increasing risk of breast cancer. According to the news release, one reason may be that this early animal research used animals that do not have certain immune cells called cytotoxic T cells. These are among the cells that act against breast tumors. Continue reading


Runner’s World Contest Winner: Running through Cancer

Running is a process – and a powerful one, says Scott Spitz, a cancer survivor who is currently featured on the cover of this month’s Runner’s World. A competitive runner, Scott continues to run through treatment for a rare form of abdominal cancer. We talked with Scott about why he runs and how running has helped him grapple with the physical and mental challenges of treatment.Scott Spitz cover

Congratulations on winning the Runner’s World Cover Contest. Why did you decide to enter?

I was a little reluctant to enter because I didn’t want to assume my story was better than others, but I’ve heard from a lot of people who said they gained something from hearing about my experience. I’ve never won anything like this before, and I was humbled and flattered that they recognized the power of my story.

What drew you to running and why have you stuck with it?

I discovered really young that I enjoyed running and had a talent for it. I ran competitively in middle and high school, but then I didn’t run for 13 years after that. I was living in a small town and wanted a physical outlet, so I went for a run and all the experiences came rushing back. I started running regularly again and never stopped. I can cite all the health benefits of running, but ultimately I run because it gives me a sense of accomplishment that has added immeasurable value to my life. Continue reading


What’s Your Nutrition Literacy?

Health literacy is important to taking care of your health, and nutrition literacy is vital to choosing healthy foods for cancer prevention. But it’s not just a matter of reading comprehension, according to the author of a study presented as a poster at our research conference yesterday.

Try these:

2. If calories are equal for one serving of each food, which provides the most healthful nutrients overall?

A. Applesauce with no sugar added

B. an appleGibbs.NLitBCa.AICRNU

C. applesauce with no sugar added is about equal to an apple in nutrition

3.. If you are trying to eat fewer than 500 mg of sodium per meal, how many cups of this food (Nutrition label) can you eat if you eat nothing else at the meal?

A. 1 cup

B. 2 cups

C. 3 cups

D. 4 cups

 

 

 

 

 

Those were three of the questions used by Heather Gibbs, PhD, at the University of Kansas Medical Center. “Literacy is a functional skill, so nutrition literacy is different than health literacy because we’re also looking at what knowledge and skills are needed in order for people to choose a healthy diet,” said Gibbs.

The three arms of her study included a group of 25 survivors who were currently in a weight-loss program; another group of 30 who were not in a program; and 17 women who were at high risk for the disease but not survivors.

Gibbs remembered one participant who read a question about finding a point of information on a Nutrition Facts label. “She read the question out loud perfectly,” Gibbs says. “But she didn’t understand how to find the answer on the label.”

Other skills Gibbs cites are evaluating fresh foods for quality, such as how much meat was marbled with fat or what colors of vegetables indicated. Participants were also asked whether they used the information on the front of labels, where marketing terms like “natural” or “organic” might make them assume a product is healthy for them; or what information they looked for if they were trying to manage their weight.

The hope is to develop a tool to help dietitians use their time educating people about the things they don’t know about or understand, says Gibbs.
