The consumption of two new probiotic strains, Lactobacillus gasseri CECT 5714 and Lactobacillus coryniformis CECT 5711, boosts the immune system of healthy humans
Orally ingested probiotic bacteria are able to modulate the immune system. However, differences exist in the immunomodulatory effects of different probiotic strains. Moreover, different regulatory effects, which depend on the health status of the consumer, have been identified. This work describes a randomized, doubleblind, placebo-controlled human clinical trial to investigate the immune effects on healthy people of a fermented product containing two new probiotic strains, Lactobacillus gasseri CECT 5714 and Lactobacillus coryniformis CECT 5711, which was compared with another fermented product, a standard yogurt. Consumption of either the new product or yogurt increased the proportion of phagocytic cells, including monocytes and neutrophils, as well as their phagocytic activity. However, combination of the product containing the strains L. gasseri CECT 5714 and L. coryniformis CECT 5711 also induced an increase in the proportion of natural killer (NK) cells and in IgA concentrations. The effects were higher after two weeks of treatment than after 4 weeks, which suggests regulation of the immune system. In addition, the new product enhanced immunity in the participants to a greater extent than did the control standard yogurt. [Int Microbiol 2006; 9(1):47-52
Factors Predicting the Response to a Vitamin D-Fortified Milk in Healthy Postmenopausal Women
Background: Milk products fortified with vitamin D may constitute an alternative
to pharmacological supplements for reaching the optimal levels of serum 25-hydroxyvitamin D
[25(OH)D]. Our aim was to analyze the response of serum 25(OH)D and its predictive factors in
postmenopausal healthy women after a dietary intervention with a milk fortified with vitamin D
and calcium. Methods: We designed a prospective study including 305 healthy postmenopausal
women who consumed a fortified milk with calcium (900 mg/500 mL) and vitamin D3 (600 IU/500 mL)
daily for 24 months. Results: The 25(OH)D concentrations at 24 months were correlated to weight,
to body mass index, to the percentage of fat, triglycerides and to baseline 25(OH)D levels. We found
significant differences in the levels of 25(OH)D at 24 months according to baseline 25(OH)D levels
(p < 0.001) and body mass index (p = 0.019) expressed at quartiles. Multivariate analysis showed an
association between levels of 25(OH)D after the intervention and at baseline 25(OH)D (Beta = 0.47,
p < 0.001) and percentage of body fat (Beta = -0.227, p = 0.049), regardless of the body mass index.
Conclusions: In healthy postmenopausal women, the improvement in 25(OH)D after an intervention
with a fortified milk for 24 months depends mainly on the baseline levels of serum 25(OH)D and on
the percentage of body fat

Dietary protein is a critical macronutrient that provides both essential and nonessential amino acids required for sustaining all body functions and procedures, providing the structural basis to maintain life and healthy development and growth in children. In this study, our aim was to describe the total protein intake, type and food sources of protein, the adequacy to the Population Reference Intake (PRI) for protein by the European Food Safety Authority (EFSA), and the Recommended Dietary Allowance (RDA) by the Institute of Medicine (IoM). Furthermore, we analyzed whether the consumption of dairy products (including regular milk, dairy products, or adapted milk formulas) is associated with nutrient adequacy and the contribution of protein to diet and whole dietary profile in the two cohorts of the EsNuPI (in English, Nutritional Study in the Spanish Pediatric Population) study; one cohort was representative of the Spanish population from one to <10 years old (n = 707) (Spanish reference cohort, SRS) who reported consuming all kinds of milk and one was a cohort of the same age who reported consuming adapted milk over the last year (including follow-on formula, growing up milk, toddler's milk, and enriched and fortified milks) (n = 741) (adapted milk consumers cohort, AMS). The children of both cohorts had a high contribution from protein to total energy intake (16.79% SRS and 15.63% AMS) and a high total protein intake (60.89 g/day SRS and 53.43 g/day AMS). We observed that protein intake in Spanish children aged one to <10 years old was above the European and international recommendations, as well as the recommended percentages for energy intakes. The main protein sources were milk and dairy products (28% SRS and 29% AMS) and meat and meat products (27% SRS and 26% AMS), followed by cereals (16% SRS and 15% AMS), fish and shellfish (8% in both cohorts), eggs (5% SRS and 6% AMS), and legumes (4% in both cohorts). In our study population, protein intake was mainly from an animal origin (meat and meat products, milk and dairy products, fish and shellfish, and eggs) rather than from a plant origin (cereals and legumes). Future studies should investigate the long-term effect of dietary protein in early childhood on growth and body composition, and whether high protein intake affects health later in life.Instituto Puleva de Nutricion (IPN)dairy company LactalisResearch Plan of the Vice-Rectorate of Research and Transfer of the University of Granada, Spai
Usual Dietary Intake, Nutritional Adequacy and Food Sources of Calcium, Phosphorus, Magnesium and Vitamin D of Spanish Children Aged One to <10 Years. Findings from the EsNuPI Study †
The authors would like to thank IPN for its support and technical advice.Bone problems in the population begin to be establish in childhood. The present study
aims to assess the usual calcium, phosphorus, magnesium, and vitamin D intakes, along with the
food sources of these nutrients, in Spanish children participating in the EsNuPI (Estudio Nutricional
en Población Infantil Española) study. Two 24 h dietary recalls were applied to 1448 children (1 to <10 years) divided into two sub-samples: one reference sample (RS) of the general population
[n = 707] and another sample which exclusively included children consuming enriched or fortified
milks, here called “adapted milks” (AMS) [n = 741]. Estimation of the usual intake shows that
nutrient intake increased with age for all nutrients except vitamin D. Using as reference the Dietary
Reference Values from the European Food Safety Authority (EFSA), calcium and magnesium intakes
were found to be below the average requirement (AR) and adequate intake (AI), respectively, in a
considerable percentage of children. Furthermore, phosphorus exceeded the AI in 100% of individuals
and vitamin D was lower than the AI in almost all children studied. The results were very similar
when considering only plausible reporters. When analyzing the food sources of the nutrients studied,
milk and dairy products contributed the most to calcium, phosphorus, magnesium, and vitamin
D. Other sources of calcium were cereals and vegetables; for phosphorus: meat, meat products,
and cereals; for magnesium: cereals and fruits; and, for vitamin D: fish and eggs. These results
highlight the desirability of improving the intake concerning these nutrients, which are involved in
bone and metabolic health in children. The AMS group appeared to contribute better to the adequacy
of those nutrients than the RS group, but both still need further improvement. Of special interest are
the results of vitamin D intakes, which were significantly higher in the AMS group (although still
below the AI), independent of age.Instituto Puleva de Nutricion (IPN
Dietary Intake of Individual (Intrinsic and Added) Sugars and Food Sources from Spanish Children Aged One to <10 Years—Results from the EsNuPI Study

G. is co-financed by the Research Plan of the Vice-Rectorate of Research and Transfer of the University of Granada, Spain.Currently, in Spain there are no studies assessing the intakes and sources of intrinsic
and added sugars by both children consuming standard milks and children regularly consuming
adapted milk formulas. Our goal was to evaluate current sugar intake levels (intrinsic and added)
and their major dietary sources within the EsNuPI study participants by applying two 24-h dietary
recalls that were completed by 1448 children (1 to <10 years) divided into two subsamples: One
“Spanish Reference Sample” (SRS) of the general population (n = 707) and another sample which
included children consuming adapted milks including follow-on milk, toddler’s or growing up milk
and fortified and enriched milks, here called “Adapted Milk Consumers Sample” (AMS) (n = 741).
Estimates of intrinsic and added sugar intakes from the Spanish EsNuPI population as well as the
adherence to recommendations varied notably according to age segment, but no major differences
between subsamples were found. Younger children (1 to <3 years) showed the highest added sugar
contribution to total energy intake (TEI) (SRS: 12.5% for boys and 11.7% for girls; AMS: 12.2% for
boys and 11.3% for girls) and the lowest adherence to recommendations set at <10% TEI (SRS: 27.4%
for boys and 37.2% for girls; AMS: 31.3% for boys and 34.7% for girls). Adherence increased with age but remains inadequate, with approximately one in two children from the older age segment (6 to
<10 years) exceeding the recommendations. Main food sources of intrinsic sugars for both subsamples
were milk and dairy products, fruits, vegetables and cereals, while for added sugars, these were milk
and dairy products (mainly yogurts), sugars and sweets (mainly sugary cocoa and nougat), bakery
products (mainly cookies) and cereals (mainly bread and wheat flour). However, for the AMS, the
groups milk and dairy products and cereals showed a significantly lower contribution to intrinsic
sugar intake but a significantly higher contribution to that of added sugars. These results demonstrate
that sugar intake and the adherence to recommendations in the studied population varied notably
according to age but not to the type of milk consumed. In addition, our results highlight the need
to monitor the consumption of added sugars by the infant population, as well as the need to make
efforts to facilitate this task, such as harmonizing the recommendations regarding free/added sugars
and the inclusion of information on their content on the nutritional labeling of products in order to
incorporate them into food composition databases.Instituto Puleva de Nutrición (IPN)dairy company LactalisResearch Plan of the Vice-Rectorate of Research and Transfer of the University of Granada, Spai

Clustering of Dietary Patterns and Lifestyles Among Spanish Children in the EsNuPI Study
Dietary patterns (DPs) are known to be tied to lifestyle behaviors. Understanding DPs and their relationships with lifestyle factors can help to prevent children from engaging in unhealthy dietary practices. We aimed to describe DPs in Spanish children aged 1 to <10 years and to examine their associations with sociodemographic and lifestyle variables. The consumption of toddler and young children milk formulas, enriched and fortified milk within the Spanish pediatric population is increasing, and there is a lack of evidence whether the consumption of this type of milk is causing an impact on nutrient intakes and if they are helping to reach the nutrient recommendations. Within the Nutritional Study in the Spanish Pediatric Population (EsNuPI), we considered two study cohorts and three different age groups in three year-intervals in each of them. The study cohort included 740 children in a representative sample of the urban non-vegan Spanish population and 772 children in a convenience cohort of adapted milk consumers (AMS) (including follow-on formula, toddler’s milk, growing up milk, and fortified and enriched milks) who provided information about sociodemographics, lifestyle, and dietary habits; a food frequency questionnaire was used for the latter. Principal component analysis was performed to identify DPs from 18 food groups. Food groups and sociodemographic/lifestyle variables were combined through a hierarchical cluster algorithm. Three DPs predominated in every age group and study sample: a palatable energy-dense food dietary pattern, and two Mediterranean-like DPs. However, children from the AMS showed a predominant dietary pattern markedly related to the Mediterranean diet, with high consumption of cereals, fruits and vegetables, as well as milk and dairy products. The age of children and certain lifestyle factors, namely level of physical activity, parental education, and household income, correlated closely with the dietary clusters. Thus, the findings provide insight into designing lifestyle interventions that could reverse the appearance of unhealthy DPs in the Spanish child populationThis research was funded by Instituto Puleva de Nutrición (IPN)S

Dietary Intake, Nutritional Adequacy and Food Sources of Total Fat and Fatty Acids, and Relationships with Personal and Family Factors in Spanish Children Aged One to <10 Years: Results of the EsNuPI Study
We aimed to determine the usual intake of total fat, fatty acids (FAs), and their main food
sources in a representative cohort of the Spanish pediatric population aged 1 to <10 years (n = 707)
who consumed all types of milk and an age-matched cohort who consumed adapted milk over the last
year (including follow-on formula, toddler’s milk, growing-up milk, and fortified and enriched milks)
(n = 741) who were participants in the EsNuPI study (in English, Nutritional Study in the Spanish
Pediatric Population). Dietary intake, measured through two 24 h dietary recalls, was compared to
the European Food Safety Authority (EFSA) and the Food and Agriculture Organization of the United Nations (UN-FAO) recommendations. Both cohorts showed a high intake of saturated fatty acids
(SFAs), according to FAO recommendations, as there are no numerical recommendations for SFAs at
EFSA. Also, low intake of essential fatty acids (EFAs; linoleic acid (LA) and α-linolenic acid (ALA))
and long-chain polyunsaturated fatty acids (LC-PUFA) of the n-3 series, mainly docosahexaenoic
acid (DHA) were observed according to EFSA and FAO recommendations. The three main sources of
total fat and different FAs were milk and dairy products, oils and fats, and meat and meat products.
The consumption of adapted milk was one of the main factors associated with better adherence to
the nutritional recommendations of total fat, SFAs, EFAs, PUFAs; and resulted as the main factor
associated with better adherence to n-3 fatty acids intake recommendations. Knowledge of the dietary
intake and food sources of total fat and FAs in children could help in designing and promoting
effective and practical age-targeted guidelines to promote the consumption of EFA- and n-3 PUFA-rich
foods in this stage of life
