INTRODUCTION: Gender differences in eating habits and protein consumption patterns are determined by cultural, socio-economic, and behavioural factors. Men tend to consume more meat, while women prefer plant-based proteins; however, the impact of these choices on body composition remains unclear.
OBJECTIVES: This study explores gender differences in protein consumption and the influence of socioeconomic status on dietary choices, evaluating their potential association with body composition parameters, including fat mass (FM%) and fat-free mass (FFM%).
METHODS: A cross-sectional study was conducted on 1708 Italian adults (721 males, 987 females). Food intake was assessed using a validated 7-day food diary. Participants were classified as non-consumers, low consumers, or high consumers according to the median intake of each protein source. Body composition was measured using bioelectrical impedance analysis.
RESULTS: Meat and processed meat consumption was significantly higher in men (p < 0.001), while women consumed more soy (p = 0.0087). Individuals with high meat and processed meat consumption had a higher BMI (p < 0.01), whereas soy consumption was associated with a lower BMI (p = 0.0027). Socioeconomic status influenced food choices: low-income men consumed more meat and processed meat compared to higher-income groups (p < 0.01), while differences in fish consumption were mainly observed in low-income groups.
CONCLUSIONS: Gender differences in protein consumption persist across socioeconomic levels and are related to body composition. Meat consumption is culturally linked to masculinity, whereas plant-based proteins are more commonly consumed by women. Understanding these dietary patterns can inform targeted nutritional interventions that promote balanced and sustainable diets.
