In the years 1993-1994 study was conducted for the assessment of the nutritional vitamin status in 133 vegetarians (VEG) - adults living in Warsaw (74 women and 59 men), and in 97 persons on usual diets (N-VEG) in similar age group (45 women and 52 men).

The risk of vitamin C biochemical deficiency was lower in VEG (8%) than in N-VEG (13%), while retinol deficiency was higher. The overall biochemical risk of folic acid deficiency was found in 34% of VEG and 36% of N-VEG persons, vitamin B6 in 48% VEG and 60% N-VEG, vitamin E standarized cholesterol in 48% VEG and 43% N-VEG.
