The food intake and nutritional status of adults on non-traditional diet were assessed. The study covered a group of twenty vegetarians with six men and fourteen women at average age of 30 years, representing different models of non-traditional nutrition and being on a vegetarian diet for 1 to 40 years. The food intake was assessed according to 24-hour recall method, being repeated three times. The nutritional status was assessed using anthropometric indices, i.e. body weight, body height and skinfold thicknesses, and heamatological indices. The vegetarian diet was found to have insufficient supply of vitamins, particularly vitamins A and C, and certain minerals, including iron, calcium and magnesium. The body weight of subjects on non-traditional diets was smaller compared with the average body weight of Polish adults and was associated with the energy intake lower than recommended. Low average intake of cholesterol and recommended intake of dietary fibre were observed in subjects on non-traditional diets, which is considered beneficial for this dietary model.
