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.


Does Exercise Help Cancer Patients and Survivors?

There’s consistent and solid evidence that physical activity reduces risk of several cancers — such as colorectal and postmenopausal breast. Data is not as strong when it comes to survival but it’s growing, especially for breast and colorectal survivors.Screen Shot 2014-10-30 at 12.23.16pm

That’s the latest from expert Christine Friedenreich, who led off the presentations about physical activity’s effect on survivorship at our research conference today.

Randomized clinical trials (RCTs) are considered the gold standard of studies, which would compare a random group of survivors who follow an exercise intervention to those not doing it. Currently, we don’t have RCTs but there is observational evidence showing benefits, said Friedenreich.

Exercise may supply its benefits in a number of ways: It may help patients complete their treatment or it could help control harms of the therapy. Animal studies suggest exercise may also help the therapy get to the tumor by improving blood flow.

But can the course of exercise alter the course of the disease? Two major studies highlighted will hopefully provide some answers. One is ALBERTA a major observational study focusing on exercise and breast cancer survivors. Then CHALLENGE is a randomized control trial investigating exercise among colon cancer survivors.

Here’s the guidelines from the American College of Sports Medicine on exercise for survivors.

And here’s the latest on our CUP report that came out this month on survival and breast cancer.


What Foods have Folate? Which have Selenium?

The hot topic that kicked off our research conference today was about how some selenium, folic acid and other micronutrients decrease cancer risk, but too much may actually increase risk. It’s delightfully termed the “Goldilocks Effect” and Glen wrote about it earlier.

All the scientists stressed that certain amounts of micronutrients show cancer protection. Supplements can give you too much. But a healthy amount of foods cannot give you the high amounts under study for harm. And these foods are loaded with plenty of other nutrients and phytochemicals linked with cancer protection and good health.

So what foods can give you selenium and folate? Here’s a few:
