The aim of this research was to analyse certain lifestyle parameters and health condition indices among people with traditional and vegetarian models of eating. The research conducted shows that vegetarians present a higher level of caring about their health, which is expressed on a scale of pro-health behaviours, than people with traditional model of eating. A higher percentage of them take up physical activity in their free time (80% vs. 70%), additionally, they more seldom drink alcohol and smoke cigarettes. Alcohol abstinence is declared by 75% of vegans, 25% of lacto-ovo vegetarians and only 8% of people with traditional model of eating. Tobacco non-smoking is declared by 94% of vegans, 74% of lacto-ovo vegetarians and 67% of traditional eating people. It has also been shown that some psychosomatic health indices, especially concerning digestive duct/system, remain varied in regard to the model of eating followed. The research has proven that vegetarian model of eating influences other--non-eating--pro-health behaviours and in this way it shapes healthy lifestyle of research subjects.
