Kasvipainotteiset ruokavaliot suomalaisessa aikuisväestössä

Plant-based diets have the potential to benefit both human and planetary health. This study aimed to investigate the prevalence of plant-based diets (vegan, lacto-vegetarian, pescatarian, and semi-vegetarian) in the Finnish adult population. We used data from the national Healthy Finland survey (2022–2023, n=28,153, response rate 46%, aged 20 years or older). Our analytical sample comprised 26,500 participants who completed a question of the frequency of consumption of nine animal- and plant-based food groups. The population shares (%) of plant-based and omnivorous diets and their 95% confidence intervals were calculated using survey weights. The population shares were 0.8% for vegan diets, 0.9% for lacto-vegetarian diets, 3% for pescatarian diets, 4% for semi-vegetarian diets, and 91% for omnivorous diets. Following a plant-based diet was more common in women, those aged 20-39 years, those living in urban areas, and those with high education compared to other groups. Following a vegan (3%), lacto-vegetarian (3%), or pescatarian (8%) diet was most common in women aged 20–39 years. These findings can be used to promote public health efforts in transition towards more plant-based and sustainable diets.
