The sale of sugary products is still strong, despite the recommendations to reduce their consumption. When children consume too much sugar, they can suffer from obesity, type 2 diabetes and cardiovascular disease. This is why health organisations recommend parents reduce their children's consumption of sugary products. One barrier to successfully reducing the sale of unhealthy products like chocolates & sugary drinks is aggressive marketing by companies producing them through ads on social media platforms such as Facebook and Instagram. Ads show people happiness, laughter and pleasure associated with their products and people feel compelled to provide such items at their events and this drives sales in a thriving industry. Social media has emerged as a distinctive marketing avenue for such an unhealthy industry. There is an urgent need to evaluate and address unhealthy marketing on social media to improve public health and nutrition.
Social media has become an important platform for health professionals to promote healthy living. However, the presence of unhealthy foods and food advertising on social media are causing concern among health professionals. This study will examine strategies and approaches of both industries that promote unhealthy choices and healthy diet promotion by health professionals on social media to identify knowledge gaps.
We shall employ deep learning and data mining technologies to examine the role of social media in the commercial promotion of unhealthy products through a public health lens. The PhD candidate will novel deep learning-based algorithms to extract knowledge from the text.
