In this morning’s session, Barbara Rolls, PhD presented info about veggie eating from her study with pre-school children. She and her research team made changes to the kids’ normal lunches so they contained more vegetables and fruits and fewer calorie-dense foods.
The question – would they increase their veggies and fruits and would they eat more food overall to make up for fewer calories at lunch? The answer is “yes” to more veggies and fruits and “no” to eating more later in the day to increase their calories.
How to get children to eat their veggies? The successful method in this case may be that they served them veggies first – carrot sticks or tomato soup – before they received other foods.
Studies have shown the same ideas work for adults as well. A simple, easy to implement idea!
At last night’s poster session, we caught up with Dr. Laura P. Hale of Duke University Medical Center. Dr. Hale’s using an AICR grant to study bromelain, a combination of enzymes found in the stems of pineapples. Specifically, she’s adding fresh pineapple juice to mouse diets to test its effect on the kind of inflammation that has been linked to colon cancer.
As you’ll see, she’s getting some very promising results.
Exercise may not be a natural instinct for many but people can change their behavior and integrate more activity into their lives. Stealth health, or the small change approach was the positive message of Dr. James O. Hill, from the University of Colorado at Denver. In order to do that, we need to think outside the box, getting communities involved and changing the culture.
Dr. Hill noted how there are very, very few people who can maintain a healthy weight if they are sedentary. In order to avoid the 1-2 pound average annual weight gain, we would need to burn about 100 calories a day. To lose about 10 to 15% of body weight one needs to burn about 200 to 300 calories per day.
The goal is to change people’s behavior but for long term change there needs to be some motivators, such as money or offsetting greenhouse gas.
He spoke about his efforts to involve the community: developers, builders, hospitals, grocery stores, restaurants – name it and it sounds like he has approached them. Get a pedometer in the grocery store and the more steps you take, the more discounts you get on the product. Every person in the community has a stake in this issue, just some people don’t know it.
A lot of people doing small change will help promote the results we want.
Dr. Hill also has a book on the small change approach.
We fund cutting-edge research and give people practical tools and information to help them prevent–and survive–cancer.
