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.


Study: Being Breastfed Links to Lower Inflammation

One of AICR’s Recommendations for Cancer Prevention is that mothers breastfeed their babies, with research showing that being breastfed can help reduce future cancer risk by helping the baby stay a healthy weight as an adult. Now a recent study suggests a new way in which breastfeeding may offer protection from cancer as well as other diseases, finding that young adults who were breastfed have a lower risk of chronic inflammation compared to those not breastfed.Mother And Baby Breast Feeding

There is a growing body of research suggesting inflammation increases the risk of many chronic diseases, including some cancers. Overweight and obesity, a risk factor for eight cancers, may produce a low level state of chronic inflammation.

AICR also recommends breastfeeding because research suggests it protects mothers against breast cancer. With August being National Breastfeeding Month, the study adds another potential benefit to the many recognized positives of breastfeeding.

Study authors used data from almost 7,000 participants who were part of national study on adolescent health. Twenty years ago, the participants were teenagers going to middle and high school.  They, and many of their parents were interviewed. Then in 2007-2008, when the participants were 24–32 years old, their levels of C-reactive protein (CRP) were measured from a blood sample. CRP is a marker of inflammation. Continue reading


Obesity and Breast Cancer Survival: Talking with Anne McTiernan

Today’s issue of Cancer Research Update highlights a new analysis of the research suggesting that obesity links to poorer survival for women diagnosed with breast cancer. The research adds to a complex and evolving field of research on lifestyle and survivorship.Tiernan photo

The findings in this paper add to the body of knowledge, but they are not proof that weight loss in overweight or obese women will improve survival, says Anne McTiernan, MD, PhD, one of the authors of the new paper and a Continuous Update Project expert panelist.

Here, Dr. McTiernan — the Director of the Prevention Center at the Fred Hutchinson Cancer Research Center — talks about the study and what it means for breast cancer survivors.

Q: This study is the first to look at BMI pre- and post-diagnosis, and 12 months following diagnosis. Why was it important to look at these three points?

A: While it’s interesting to know what effect BMI before diagnosis has, women want to know what they can do now, for their future. So it’s important to look at the post-diagnosis period. Continue reading
