To simulate the impact on calcium intake – effectiveness and safety – of fortifying wheat flour with 200, 400 and 500 mg of calcium per 100 g of flour.

Secondary analysis of cross-sectional data collected through repeated 24 h dietary recalls using the Iowa State University Intake Modelling, Assessment and Planning Program.

Urban cities in the National Health and Nutrition Survey of Argentina (ENNyS 2018–2019).

21 358 participants, including children, adolescents and adults.

Most individuals in all age groups reported consuming wheat flour. The prevalence of low calcium intake was above 80 % in individuals older than 9 years. Simulating the fortification of 500 mg of calcium per 100 g of wheat flour showed that the prevalence of low calcium intake could be reduced by more than 40 percentage points in girls and women aged 19 to less than 51 years and boys and men aged 4 to less than 71 years, while it remained above 65 % in older ages. The percentages above the upper intake level remained below 1·5 % in all age groups.

Calcium flour fortification could be further explored to improve calcium intake. Subnational simulations could be performed to identify groups that might not be reached by this strategy that could be explored in Argentina. This analysis could be used to advocate for a strategy to fortify wheat flour.

To assess the energy and nutrient intakes of healthy infants from low-income families and to compare intakes with current recommendations.

We interviewed mother–infant pairs longitudinally when the infants were 3, 6, 9, 12, 18 and 24 months old. Food intake data were obtained by 24-hour dietary recalls. Selected nutrient intakes were calculated and compared with the Recommended Dietary Allowances (RDAs).

Infants (n = 200) were the offspring of low-income, pregnant women recruited at the Albany County Department of Health, New York for the Albany Pregnancy and Infancy Lead Study, a prospective investigation of factors related to blood lead levels, including nutrition. Interviews were conducted during paediatric clinic visits.

Means and standard deviations were used to describe energy and micronutrient intakes for age groups. The probability approach was utilised to examine the prevalence of inadequate intakes.

Mean energy and nutrient intakes generally met or exceeded the RDA. The exceptions were vitamin D and zinc for which observed means were below the RDA at several data points. Protein consumption was exceptionally high in this sample. The highest estimated prevalences of inadequate intakes were observed for iron, zinc and vitamin D at the older ages.

This study identified several potential concerns about the diets of infants during the transition from infant food and formula to table foods. Low intakes of vitamin D, zinc and iron, especially at 12 and 18 months, were observed. High protein intakes were noted at all ages.

To describe vitamin intakes in Spanish food patterns, identify groups at risk for inadequacy and determine conditioning factors that may influence this situation.

Pooled-analysis of eight cross-sectional regional nutrition surveys.

Ten thousand two hundred and eight free-living subjects (4728 men, 5480 women) aged 25–60 years. Respondents of population nutritional surveys carried out in eight Spanish regions (Alicante, Andalucía, Balearic Islands, Canary Islands, Catalunya, Galicia, Madrid and Basque Country) from 1990 to 1998. The samples were pooled together and weighted to build a national random sample.

Dietary assessment by means of repeated 24-hour recall using photograph models to estimate portion size. Adjusted data for intra-individual variation were used to estimate the prevalence of inadequate intake. A Diet Quality Score (DQS) was computed considering the risk for inadequate intake for folate, vitamin C, vitamin A and vitamin E. DQS scores vary between 0 (good) and 4 (very poor). Influence of lifestyle (smoking, alcohol consumption and physical activity) was considered as well.

Inadequate intakes (<⅔ Recommended Dietary Intake) were estimated in more than 10% of the sample for riboflavin (in men), folate (in women), vitamin C, vitamin A, vitamin D and vitamin E. More than 35% of the sample had diets classified as poor quality or very poor quality. Factors identified to have an influence on a poor-quality diet were old age, low education level and low socio-economical level. A sedentary lifestyle, smoking, usual consumption of alcohol and being overweight were conditioning factors for a poor-quality diet as well.

Results from The eVe Study suggest that a high proportion of the Spanish population has inadequate intakes for at least one nutrient and nearly 50% should adjust their usual food pattern towards a more nutrient-dense, healthier diet.
