Excess mortality and morbidity among Irish farmers from non-communicable diseases (NCDs) has been linked to a range of occupational risk factors. Obesity is a key risk factor underpinning this excess burden and unhealthy eating habits are linked to overweight/obesity and to disease occurrence. This study investigated the dietary habits of a sub-group of Irish male farmers and explored how these might potentially impact on health outcomes. Cross-sectional survey research was undertaken using self-reported quantitative data, based on convenience sampling and a 24-h food re-call survey. Data were analysed using frequency and chi-square analysis. Where possible, findings were compared to national survey data for Irish males. Findings revealed that a high proportion of farmers were overweight or obese and that dietary habits consisted of low intake of fruit, vegetables, and dairy and a high intake of meat, fried and processed foods, salt, and sugary and/or salty snacks. Younger farmers reported a significantly higher intake of processed meats; however, no associations were found between age, lifestyle behaviours, and dietary habits. The findings provide a greater understanding of how dietary habits potentially contribute to poorer health outcomes among farmers and underline the need for health promotion interventions, including healthy eating campaigns, aimed at farmers.
