A public health survey in Hong Kong revealed that 50% of people aged 15 to 84 were either overweight or obese due to insufficient intake of whole grains, fruits and vegetables, and the increasing consumption of sugary and alcoholic beverages, ready meals, food and other foods with high density and low nutrient content.

The research conducted by Dr. Louisa Chung Ming-yan, assistant professor at the Department of Health and Physical Education, The Education University of Hong Kong (EdUHK), found that public education to promote awareness of healthy eating and transfer of knowledge about balanced diet has played a role. a key role in positively changing people’s eating behavior in Hong Kong. It turns out, however, that younger adults lack skills in planning, buying, cooking and preparing healthy meals at home and tend to choose nutritionally inadequate pre-packaged foods. Establishing healthy eating habits is considered to be a sustainable strategy for good health maintenance, and mobile apps are expected to be a highly effective way of promoting healthy eating among young adults. However, there are few interventions that use apps to improve the adult behavior of younger adults.

In this study published in Nutrients, a diet monitoring mobile app, called the “eDietary Portal”, integrated with behavioral feedback, was evaluated in individuals aged 19 to 39. The primary purpose was to examine the effectiveness of the app in improving nutrition and diet in younger adults by to increase the consumption of fruits, vegetables and whole grains and decrease the consumption of salt and sugar.

Both the experimental group and the control group received a three-hour nutrition seminar, but the experimental group also underwent 12 weeks of diet monitoring with the app. Behavioral feedback provided by the app was evaluated to facilitate the transfer of nutritional knowledge to nutritional behavior. Baseline and post-intervention nutritional knowledge and dietary behaviors were collected. All mean scores of post-GNKQ-R increased from baseline for both control and experimental groups.

The study showed that both the control group and the experimental group improved their nutritional knowledge thanks to the seminar, but the app encouraged dietary reflection, making the subjects more able to match food products to food categories, choose healthy foods, and select foods. to reduce health problems and the risk of disease.

Both the control group and the experimental group increased their intake of dietary fiber, whole grains and fruits and vegetables, but the increase was greater in the experimental group, especially fruit and vegetable consumption. The experimental group reduced sugar consumption more than the control group, but the difference in salt consumption was insignificant. Larger individuals in the experimental group were more likely to increase fruit consumption.

The research concluded that the integration of healthy food knowledge transfer with a mobile app is essential for technology-immersed young people. Promoting healthy eating habits performed with appropriate technology apps can help users acquire information flexibly in terms of time, pace and location, can be tailored to individual needs, and allows for reflection by users.
