“…The FFQ tend to estimate higher mean intakes for most nutrients compared to the 24-hour recall [67]. In the two Swedish surveys, the regional FFQ study from Umeå [52] reported a mean dietary iron intake of 14.5 mg/day, while the nationwide 4 days food diary study [53] reported a significantly lower intake of 9.4 mg/day.…”

Objective. Assessment of dietary iron intake in women of reproductive age in Europe. Design. Review. Setting. Literature search of dietary surveys reporting intake of iron using PubMed, Internet browsers, and national nutrient databases in the period 1993–2015. Subjects. Women of reproductive age. Results. 49 dietary surveys/studies in 29 European countries were included. Belgium, Bosnia, Denmark, Hungary, Italy, Northern Ireland, Serbia, Scotland, Sweden, Switzerland, United Kingdom/England, and Wales reported a median/mean iron intake of 7.6–9.9 mg/day. Finland, Iceland, Ireland, the Netherlands, Norway, Poland, and Spain reported an intake of 10.0–10.7 mg/day. Austria, Estonia, France, and Russia reported an intake of 11.0–11.9 mg/day. Latvia and Germany reported an intake of 12.0–12.2 mg/day. Croatia, Lithuania, Portugal, and Slovakia reported an intake of 15.9–19.0 mg/day. The percentage of dietary iron consisting of heme iron, reported in 7 studies, varied from 4.3% in United Kingdom to 25% in Spain. Nutrient density for iron (mg iron/10 MJ, median/mean) varied from 11.8 in Sweden to 23.0 in Lithuania. The correlation between nutrient density and dietary iron was significant (p=0.0006). In most countries, the majority of women had a dietary iron intake below 15 mg/day. In Belgium, Denmark, Hungary, and Sweden, 91–95% of women had an intake below 15 mg/day. In Ireland and Germany, 61–78% had an intake below 15 mg/day. Conclusions. In Europe, 61–97% of women have a dietary iron intake below 15 mg/day. This contributes to a low iron status in many women. We need common European standardized dietary methods, uniform dietary reference values, and uniform statistical methods to perform intercountry comparisons.

“…However, the number of food products included in such questionnaires may be very high. Such questionnaires, covering inter alia folate intake assessment, commonly include over 100 items [ 42 , 43 , 44 , 45 , 46 ], or even over 200 items, while it is stated that completing a 235-item questionnaire adapted by Fayet [ 20 ] from the 145-item Blue Mountain Eye Study Food Frequency Questionnaire [ 47 ] takes approximately 45 min [ 20 ].…”

The tools enabling brief assessment of folate intake may be of great value for public health purposes. The aim of the presented study was to design a brief folate-specific food frequency questionnaire for Central and Eastern European population of women, as well as to assess the validity and reproducibility of the designed Folate-Intake Calculation-Food Frequency Questionnaire (Fol-IC-FFQ) on a group of Polish women aged 20–30 years. Participants collected 3-day dietary records and completed the Fol-IC-FFQ twice (FFQ1: directly after the dietary record; and FFQ2: six weeks later). The analysis included an assessment of validity (comparison of the results of FFQ1 and 3-day dietary record) and of reproducibility (comparison of the results of FFQ1 and FFQ2). In assessment of validity, a Bland-Altman index of 5.3% was observed. In assessment of reproducibility, a Bland-Altman index of 2.7% was observed, the share of individuals classified into the same intake adequacy category was over 85%, the share of individuals classified into the same tertile was almost 75%, the weighted κ statistic indicated substantial agreement (0.67) and correlation was significant (p = 0.0000; R = 0.7995). Assessment of the Fol-IC-FFQ revealed a satisfactory level of validity and very good level of reproducibility in the population of young Polish women. The Fol-IC-FFQ may be considered a valid tool for the assessment of folate intake in young Polish women and a promising tool for the assessment of folate intake in young women in Central and Eastern Europe.

“…The relative validity is often assessed by the use of different statistical analyses, including correlation coefficients, Bland-Altman plots, cross-classification, and weighted Cohen’s kappa coefficients [ 179 , 180 , 181 , 182 , 183 , 184 ]. However, only a few recent studies have reported on the validation of methods to assess choline and betaine intakes [ 159 , 185 , 186 , 187 ]. This could be related to the fact that the first food composition database for these nutrients only became available for use less than 15 years ago [ 148 ].…”

“…A tendency for higher absolute choline and betaine intakes estimated from an FFQ compared to the mean intake from the reference method has been reported in the United States and Europe [ 159 , 186 , 187 ]. In addition, the estimated energy intake tended to be higher in the FFQ compared to 24HR, which supports the overestimation of intakes.…”

Dietary Choline Intake: Current State of Knowledge Across the Life Cycle

Choline, an essential dietary nutrient for humans, is required for the synthesis of the neurotransmitter, acetylcholine, the methyl group donor, betaine, and phospholipids; and therefore, choline is involved in a broad range of critical physiological functions across all stages of the life cycle. The current dietary recommendations for choline have been established as Adequate Intakes (AIs) for total choline; however, dietary choline is present in multiple different forms that are both water-soluble (e.g., free choline, phosphocholine, and glycerophosphocholine) and lipid-soluble (e.g., phosphatidylcholine and sphingomyelin). Interestingly, the different dietary choline forms consumed during infancy differ from those in adulthood. This can be explained by the primary food source, where the majority of choline present in human milk is in the water-soluble form, versus lipid-soluble forms for foods consumed later on. This review summarizes the current knowledge on dietary recommendations and assessment methods, and dietary choline intake from food sources across the life cycle.
