Health and wellbeing have been identified as one of the key Consumer Lifestyle Trends by Bord Bia (Bord Bia, 2019). Consumers have become increasingly aware of the influence that their diet has on their body, and the COVID-19 pandemic has heightened this awareness even further. During the initial outbreak of COVID-19 in March 2020, Google searches featuring the three terms ‘food’, ‘immune’ and ‘system’ surged in the UK (Mintel, 2020) as people began to enhance their efforts of self-maintenance.

 

As a result of the intermittent lockdowns of 2020, high rates of loneliness, depression, anxiety and post-traumatic stress disorders were reported across Irish adults (Maynooth University, 2020). While the propagation of psychiatric conditions is incredibly complex and multifactorial, it is scientifically accepted that dietary intake plays a role in mental wellbeing (British Medical Journal, 2020). Food manufacturers are starting to pay more attention to the inclusion of ingredients that are said to improve mood (Euromonitor, 2020), including probiotics that contribute to healthy gut microbiome composition. Gut microbiome interact with the brain using neural, inflammatory and hormonal signalling pathways, which research suggests may influence brain development and function (Kelly et al, 2019). Further scientific research is needed in this area, but there has certainly been increased consumer interest in the link between gut microbiome and mood (Euromonitor, 2020).

 

The COVID-19 outbreak has not only exposed people to daytime stresses, research has shown that it has also disrupted sleep (Altena et al, 2020), which plays a crucial role in emotion regulation (American Psychological Association, 2014). There is substantial evidence that indicates the role of different dietary behaviours have on sleep quality (St-Onge et al, 2016), and consumers are now looking for natural solutions and food with targeted functionality, including sleep-aid ingredients (Euromonitor, 2020).

 

These are just two examples of functional foods continuing to show opportunities for Irish food manufacturers. Euromonitor estimates that the sector was worth €733.1 million in 2020 (Euromonitor, 2021). The consumer emphasis on health and wellbeing has continued to heighten since the outbreak of COVID-19.
