A comparative content analysis of food marketing strategies on social media used by big food and beverage companies
Purpose The marketing of ultra-processed and discretionary foods on social media is a growing driver of dietary choices and consumer engagement, particularly among younger users. As food brands increasingly invest in digital media, understanding the strategies they use across platforms is essential for informing public health interventions and policy. Despite this shift, few studies have compared marketing strategies and engagement outcomes acros…
The Pear Tool
Previous research has established where and what types of advertising are in children's neighbourhoods. However, no prior research has evaluated the portion sizes in advertisements or how these compare with national dietary recommendations. This study aimed to evaluate portion sizes in advertising on bus shelters surrounding schools in Auckland, New Zealand using images captured on Google Street View. Portion sizes for 265 foods or beverages in 1…
Assessing food availability and healthier options in an urban Chinese university
Young adults (18-24 years) in universities are frequently exposed to an environment that promotes unhealthy eating behaviors. Using a validated tool, the Chinese Nutrition Environment Measurement Survey for Stores (C-NEMS-S), we assess the food availability and healthier options in a large, urban Chinese university. We employed C-NEMS-S for scoring criteria and weighting. A total of 52 on-campus canteen outlets were audited in an urban university…

This study protocol discusses the co-design and co-development of a social media health promotion program for young women. The program aims to disseminate evidence-based health information and promote healthy behaviours among young women aged 18-24 years. The evidence-base for social media interventions is explored, with examples of successful health promotion programs using social media platforms for example, Facebook. The social media health pr…

COVID-19 impact on global and national food systems, along with associated physical restrictions, lockdowns, and school closures, have led to dramatic changes in families' everyday food practices. Our research explored the way food practices adapted and emerged, allowing families to cope with the disruption caused by COVID-19. We recruited 18 low socio-economic status families with primary school children across the United Kingdom and New Zealand…
Does labelling of healthy foods on menus using symbols promote better choices at the point-of-purchase
Objective: Take-away foods account for a significant proportion of dietary intake among young adults (18–35 years). Young adults want nutrition information at the point-of-purchase (POP); however, it is either unavailable, perceived as ineffective or difficult to use. The present study examined whether symbols on university food outlet menus identifying healthier options would increase their sales and consumer’s awareness of these symbols, purcha…
The Effect of Energy Labelling on Menus and a Social Marketing Campaign on Food-Purchasing Behaviours of University Students
Point-of-purchase energy labelling may be an effective method to encourage better food choices when eating out among young adults. However, further efforts to increase awareness and provide education about energy requirements to prevent weight gain will be needed
