The aim of this work was evaluation of lutein intake in group of 110 adolescents from big city (Warsaw) and little town (Iłza). The group consisted of 56 girls and 54 boys, high school attending persons, aged 16 - 20. The study was carried in the spring of 2007, with the use of three-days dietary food records method. The mean intake of lutein was 1.87 mg/person/ day and it was dependent on respondents sex. Girls consumed 1.67 mg per day of lutein, while boys consumed 2.07 mg per day. Index of BMI, place of dwelling, place of study, physical activity, mother occupation as well as amount of siblings did not have an impact on the intake of lutein. The main sources of lutein in adolescents food rations were vegetables (64%), including dark-green leafy vegetables (40%), eggs (12%) and cereal products (12%). Potatoes (5%), fruit (3%) and juices (3%) did not contribute significant amount to dietary intake of lutein.

The aim of the study was to estimate dietary intake of lycopene by the group of 100 women, from Central Poland, in different age <30 years, 30-50 years, >50 years (mean age 49 +/- 16 years) and main sources of lycopene. The study was carried out in the year 2006 (June-July) with the use of 4-day dietary food records. The lowest intake of lycopene was noted in the youngest group--4.17 mg/person/day, the highest intake in the oldest group--4.88 mg/person/day. The main sources of lycopene in food rations were tomato products (50.6%) and fresh tomatoes (43.5%). Tropical fruit delivered 5.2% of lycopene, other fruit and vegetable juices only 0.7%. Intakes of products, sources of lycopene, depended on age of women and were statistically significant in case of tomato, watermelon, pink grapefruit, and tomato products: ketchup, liquid tomato sauces, liquid tomato soups, tomato juice.

Given the range of natural mineral waters, natural spring waters and table waters, and their degree of mineralization (from low to the high), it can be assumed that they will become increasingly important as a source of minerals in everyday diet. The aim of the study was the assessment of the amount of bottled waters consumption as well as contained selected minerals in waters among female students. Study was conducted among 18-26 years old students from Warsaw University of Life Sciences (SGGW) and Cardinal Stefan Wyszyński University in Warsaw (UKSW) (50 female from each), from May to October 2010 year. The study was performed by using the questionnaire concerned habitual consumption of bottled waters. Intake of calcium, magnesium, sodium, potassium, silicon, chlorine and fluorine, as the major components of water declared on the label packaging, was also estimated. Almost 40% of respondents consumed four glasses of water a day, about 24% - 2 glasses, about 24% - 3 glasses, 11% - 1 glass, but it was mainly low- and medium-mineralized water. The average daily intake of calcium, magnesium, sodium, potassium, chlorine and fluorine in the study population was respectively: 64.1, 26.5, 14.3, 1.9, 5.4, and 0.1 mg per person. Intake of silicon was 14, 4 mg/person/day. Among minerals only calcium and magnesium intake with waters was comparatively significant (6% and 8% of reference values, respectively). Bottled waters were not a significant source of minerals, but they can be a valuable addition to daily diet. There is a need to promote the drinking of natural mineral waters, spring waters and table waters, especially highly-mineralized and low-sodium waters as a source of well-absorbed minerals.

The aim of the work was to assess the application of diet supplements in pregnant women, as well as the intake of vitamins and minerals with pharmaceuticals. Sixty women in age 19 - 40 years coming from the Mazowsze district were examined. The information about applying supplements was obtained using questionnaire method. The intake of vitamin and mineral supplements before and during pregnancy was declared on the level of 55% and 98.3% respectively. The average intake of vitamin D (157%), folic acid (128%), vitamin B2 (125%), vitamin C (121%), iron (120%), iodine and zinc (113%) from supplements was above recommended values. The average intake of vitamin B1, B12 and B6 from supplements was about 95-105% of RDA. The lowest average consumption was noted for vitamin A (60%) as well as calcium and magnesium (10-12% of recommended value). Pregnant women who have lived in country consumed less vitamins and minerals from supplements, however differences were statistically significant in case vitamin A, E, magnesium, cooper, iodine and manganese.

Children and adolescents are the most vulnerable for the impact of improper nutrition. The mode of nutrition is one of the factor influencing the proper development and growth of young organism and the maintenance of good health until advanced old age. The food pattern of youth from selected Warsaw gymnasium and lyceum was evaluated. Author's questionnaire, 24h interview and Block questionnaire were used. Irregularity of main meals intake, between meals consumption (sweets and salts snacks mainly and fruits also) as well as tea, fruit juices and mineral water drinking were observed in youth of both schools. More than half of them took cola drinks every day and half of youth drank coffee permanently. The daily ratios of both groups were short in fibre and too rich in fats. Fats intake was more proper among gymnasialists. Youth's daily ration in both types of school were poor in vitamin C, D, E as well as calcium, potassium and magnesium. They were too rich in vitamin A in some cases (7%) over UL. Also, vitamin B2, B6 i B12 and sodium, copper, iron (boys) exceeded recommendations. No statistically significant differences in food pattern between gymnasium and lyceum youth were observed however in girls the one was more proper. In order to optimise the mode of nutrition the monitoring established on the constant base and education for parents, teachers and adolescents are needed.
