[Comparative assessment of carotenoids intake by food frequency questionnaire and 4-day dietary food records method].
The aim of the work was comparative assessment of beta-carotene, lycopene and lutein intake by two methods: food frequency questionnaire and 4-day dietary food records. Subjects were 130 female volunteers, aged 18 to 25 years, Warsaw University of Life Sciences students. Data were collected in spring/summer 2005. Intakes of beta-carotene (3.62 vs. 3.49 mg/day per person), lycopene (4.54 vs. 4.05 mg/day per person) and lutein (2.50 vs. 2.12 mg/day per person, respectively) estimated these methods were not statistically significant. The mean differences in intakes assessed were higher for food frequency questionnaire (respectively 3.7% for beta-carotene; 12.1% for lycopene; 1.9% for lutein). Statistically significant Pearson correlations were observed between estimation of carotenoids intake by two methods (r = 0.82 for beta-carotene, r = 0.75 for lycopene, r = 0.73 for lutein; p < 0.001). Main sources of beta-carotene were vegetables supplied 90% of this carotenoid (therein carrot 54%). Tomato products and fresh tomatoes contributed 60-61% and 30% of lycopene/day respectively. Sources of lutein were fresh vegetables contributed to diet 54-60% of lutein (therein leafy vegetables 25-30%).
