This study investigates the moderating effect of consumer empowerment on the relationship between involvement in and purchase behaviour towards eco‐friendly food. It uses the generalized linear model, with data from the 2017 Research on Food Consumption. The results showed that gender is related only to involvement in eco‐friendly food and this involvement is higher for women than for men. Moreover, involvement in eco‐friendly food, purchase empowerment, engagement empowerment and frequency of buying eco‐friendly food increase as age increases, with the highest increases observed at ages 40–49 and 50–59; the score for those older than these age groups was much lower, resembling an inverted U shape. Groups with high education and income levels presented high scores for involvement in eco‐friendly food, purchase empowerment, engagement empowerment and frequency of buying eco‐friendly food. Regarding the effects of involvement in eco‐friendly food, purchase empowerment and engagement empowerment on the frequency of buying eco‐friendly food, the main effects of involvement in eco‐friendly food and purchase empowerment as well as the interactive effects between involvement in eco‐friendly food and engagement empowerment were statistically significant.
