How a new app could help people eat more fruits and vegetables
Jan. 5, 2023 Medical News Today
Regular consumption of fruits and vegetables may help reduce the risk of developing certain health conditions.
Despite government guidelines to increase fruit and vegetable intake worldwide, consumption in Europe, the United States, and across the globe remains low.
Recently, researchers from the University of Bournemouth released a new app called “SMART 5-A-DAY” to help users track and increase their fruit and vegetable intake.
Prof. Katherine Appleton, professor of psychology at the University of Bournemouth and one of the app’s creators, told Medical News Today:
“The app is based on the U.K. 5-a-day recommendations, and fruit and vegetable recommendations can vary around the world based on the local fruits and vegetables available, local portion sizes, and other local nutritional concerns. Recommendations to consume lots of fruits and vegetables, however, apply everywhere.”
The app was released in the Google Play Store for Android phones on December 29, 2022.
Why aren’t people eating enough fruits and veggies?
Research shows that knowledge about the benefits of fruit and vegetable consumption is lacking and directly linked to lower overall consumption.
Potential factors impeding fruit and vegetable intake may include:
- poor knowledge or confusion around nutritious fruits or vegetables
- portion sizes for fruits and vegetables
- the number of portions needed per day
- the need for a variety of fruit and vegetables
- benefits of high fruit and vegetable consumption
Increasing awareness around what constitutes adequate fruit and vegetable consumption could help individuals improve their overall health.
‘SMART 5-A-DAY’ app: How it works
To use the app, users input what fruits and vegetables they’ve eaten after each meal and how much.
The app then converts consumption to correspond with U.K. guidelines of five portions of different fruits or vegetables per day. The app allows users to track their daily consumption over time.
“The app only includes fruit and vegetables that count toward the U.K. recommendations, so those that do not count toward the U.K. recommendations, such as potatoes, cannot be added,” Dr. Appleton explained.
She added that one of the app’s key benefits is that it will help users recognize how few fruits and vegetables they consume, which may alert them to improve their diets.
“Our hope is that use of the app over a number of weeks will increase understanding of these elements such that the app is not required further, but people have the knowledge themselves of what they need to do,” she said.
A 2019 study on the SMART 5-A-DAY app found a modest increase in participants’ knowledge of fruit and vegetable intake recommendations.
Since that time, researchers have incorporated several updates based on user feedback and expect this will have a positive impact on the overall consumption of fruits and vegetables.
“Research has also found tracking a health-related goal is linked to a greater chance of achieving the goal,” Debbie Fetter, Ph.D., assistant professor of teaching nutrition at the University of California, Davis, not involved in the study, told MNT.
“Using an app can give consumers a place to document their efforts and see their progress add up. However, it’s not a requirement to use an app; tracking a health-related goal with pencil [and] paper also works great,” Dr. Fetter added.
How food tracking apps help improve diet
To understand more about how the SMART 5-A-DAY app might help individuals improve their diet, MNT spoke with Sara Kostelnick, MS, RD, a sports performance dietitian at the University of Kansas Health System (not involved in the study).
“As a dietitian, I often see fruit and vegetable intake is forgotten about when making healthy lifestyle changes,” Kostelnick said.
“Many studies have investigated tracking as a means of increasing accountability and reaching health goals that you’ve set for yourself. Translating this to meet fruit and vegetable needs can help users increase their daily fruit and vegetable consumption,” she added.
MNT also spoke about the new app with Dena Champion, MS, RDN, a registered dietitian at the Ohio State University Wexner Medical Center:
“This app appears colorful, simple to use, and interactive. It includes a calculator which gives a target of 5 servings of fruits and veggies a day. This may be a helpful visual for people trying to increase their fruit and veggie consumption but aren’t sure of serving sizes or how close they are to meet this goal.”
Champion noted, however, that not everyone may find the app helpful.
“Everyone learns differently and is motivated differently. Some people thrive on this kind of app that requires tracking foods and provides feedback, while others find this annoying or unhelpful,” Champion said.
