Thousands of studies carried out across 42 years were analysed to see which treatment yielded the best results and helped people with type 2 diabetes change their behaviour.
Researchers from the University of British Columbia (UBC) found the intervention which garnered the best results was when healthy diet were provided and participants had regular contact and help from dieticans.
According to Kevin Cradock, the study's first author and an Irish Research Council postgraduate scholar at the National University of Ireland (NUI) Galway: "Changing the food environment is one of the keys to treating type 2 diabetes. Before we change the food environment we need to look carefully at what it is and how it affects us."
Feedback on behaviour, solving problems and comparing themselves to others are three major techniques found by the research team that help people change their attitudes to food
Professor Heather Gainsforth, an assistant professor at UBC Okanagan's School of Health and Exercise Sciences, remarked: "Without any support, behaviour change efforts can quickly fall apart. We need to be thinking about a better way to support people with diabetes.
"It may seem impractical to provide food and control the food environment. However, we need to examine the viability of providing healthy meals at the beginning of a program, followed by instruction and feedback as to how to choose, shop for and prepare these foods. Gradually, this approach may support people to prepare healthy meals independently."
