Risk Factors for a Higher Dietary Acid Load (Potential Renal Acid Load) in Free-Living Elderly in Poland.

Background: Dietary composition is one of the factors influencing the acid-base balance of the body by providing acid or base precursors. One of the methods for assessing the acid-forming potential of a diet is to calculate its potential renal acid load (PRAL). The aim of this study was to identify the sociodemographic, lifestyle, and health factors related to the PRAL.

The Association of Nutrition Quality with Frailty Syndrome among the Elderly.

Low diet quality among the elderly may be correlated with some diseases, including Frailty Syndrome (FS). This decline in function restricts the activity of older people, resulting in higher assistance costs. The aim of this study was to increase knowledge of diet quality predictors.

Vitamin B-6 intake is related to physical performance in European older adults: results of the New Dietary Strategies Addressing the Specific Needs of the Elderly Population for Healthy Aging in Europe (NU-AGE) study.

Background: Maintenance of high physical performance during aging might be supported by an adequate dietary intake of niacin, vitamins B-6 and B-12, and folate because these B vitamins are involved in multiple processes related to muscle functioning. However, not much is known about the association between dietary intake of these B vitamins and physical performance.

Objectives: The objectives of this study were to investigate the association between dietary intake of niacin, vitamins B-6 and B-12, and folate and physical performance in older adults and to explore mediation by niacin status and homocysteine concentrations.

Intake of Vitamins and Minerals From Voluntarily Fortified Foods and/or Dietary Supplements in School Adolescents in Central-Eastern Poland.

The key issue is whether voluntarily fortified foods and vitamin/mineral supplements available on the market serve public health needs. The study aim was to estimate nutrient intakes from voluntarily fortified foods and vitamin/mineral supplements in relation to the Dietary Reference Intake (DRI) in adolescents ( = 759) aged 13-19 who attended public secondary schools in Central-Eastern Poland. Data on the consumption of voluntarily fortified foods were collected using a semi-quantitative food frequency questionnaire containing 58 food items.

The Influence of Iron and Zinc Supplementation on Iron Apparent Absorption in Rats Fed Vitamins and Minerals Reduced Diets.

Deficient human diet is usually reduced in many nutrients, but animal studies on iron absorption have been only carried out for rats fed well-balanced (control) and iron-deficient diets. The aim of this study was to evaluate the effect of iron or iron/zinc supplementation on iron apparent absorption (IAA) in rats fed a diet reduced in all vitamins and minerals (R). The study was conducted on 77, 6-week-old male Wistar rats in 3 stages as follows: stage I, 4-week period of adaptation to R diet (50% less vitamins and minerals compared to AIN-93M recommendations); stage II, 4-week supplementation period with iron (RSFe) or iron/zinc (RSFeZn); stage III, 2-week post-supplementation period (rats fed R diet).

Intake of Vitamins and Minerals from Voluntarily Fortified Foods in School Children in Central-Eastern Poland.

Objective: To estimate vitamin and mineral intakes from voluntarily fortified foods (VFFs) in relation to the Dietary Reference Intake (DRI) in children aged 6 - 12. The study was conducted among 677 school children from Central-Eastern Poland. Data on VFFs consumption were collected using a semi-quantitative food frequency questionnaire containing 58 food items available on the Polish market; the content of nutrients in VFFs was estimated using the producers labelling declaration.

Reprint of: A parallel randomized trial on the effect of a healthful diet on inflammageing and its consequences in European elderly people: design of the NU-AGE dietary intervention study.

Background: The proportion of European elderly is expected to increase to 30% in 2060. Combining dietary components may modulate many processes involved in ageing. So, it is likely that a healthful diet approach might have greater favourable impact on age-related decline than individual dietary components.

[Influence of selected factors on fortified food intake by children].

Background: The range of food products fortified with vitamins and minerals in Poland is growing rapidly in the last years. Also the consumption of such food and dietary supplements is increasing. Therefore there is a risk of excessive intake of vitamins and minerals.

[Factors influenced vitamin or mineral supplements use in a chosen group of children aged 6-12].

Background: Due to growing popularity of food supplements the producers of such products introduce food supplements developed especially for children. This, as a consequence, may lead to a risk of exceeded intake of some nutrients.

Objective: The aim of this study was to identify determinants of vitamin/mineral supplements intake in 6-12-year-old children.
