Vegetarians and vegans as probably the most frequent consumers of soy foods can be exposed to higher cadmium load from these foods than individuals with non-alternative eating. Regular intake of cadmium can lead to its long-term accumulation in human body before clinical manifestations. This research confirmed that vegetarians and vegans are exposed to a significantly higher load of cadmium from soy foods compared to those who eat in a non-alternative way, and a higher intake of cadmium from soy foods in vegans compared to vegetarians. Soy foods that contributed most to the supply of cadmium to vegetarians/vegans soy milk and tempeh. Respondents (n=71) were divided into three groups: vegetarians (n=16), vegans (n=28), and people with non-alternative eating (n=27). Methodology of this study includes laboratory measurements of cadmium content in soy products and dual data collection - a preliminary questionnaire survey in electronic form and a semiquantitative food frequency questionnaire with personal assistance.
