“…Biomarkers of dietary intake, such as urinary nitrogen and electrolytes, have been applied in nutritional validation studies. Based on our correlation coefficients, present data are within the range observed previously (Kroke et al, 1999), indicating (Harbige, 1996). The deficiency of vitamin D, whose biologically active form is a potent modulator of the immune system, has been suggested among the dietary putative etiological factors in the pathogenesis of T1DM (Akerblom et al, 2002;Zella & DeLuca, 2003).…”

Objective: Nutritional status and lifestyle can have profound effects on health. To analyse behaviour patterns in population subgroups of public health importance, we compared lifestyle, dietary intake of energy and selected nutrients, and nutritional biomarkers of type 1 diabetes (T1DM) patients and nondiabetic first-degree relatives against control subjects with no family history of T1DM. Design: A cross-sectional study. Setting: Department of Internal Medicine, University of Pisa, Italy. Subjects: A total of 209 individuals including 38 type 1 patients, 76 relatives, and 95 healthy subjects. Interventions: We used the European Prospective Investigation of Cancer and Nutrition questionnaires to assess dietary intake and lifestyle. Anthropometric indices and nutritional biomarkers (such as plasma levels of albumin, iron, lipids, homocysteine, vitamin B 9 and vitamin B 12 as well as urinary outputs of nitrogen, sodium and potassium) were evaluated. Results: Emerging health issues: (1) In total, 45% of controls were overweight. Increasing age was associated with increasing body mass and decreasing activity in sport in front of an unchanged energy intake.(2) The distribution of energy sources was incorrect. The proportion of caloric intake derived from total fat and cholesterol did not match general guidelines. Total dietary fibre consumption was assessed to be adequate (25 g/day) in only 27% of all the participants. (3) Estimated daily intakes of water-soluble vitamin B 9 and fat-soluble vitamin D and vitamin E were deficient in comparison with dietary reference intakes. (4) The prevalence of adoption and maintenance of healthful eating and physical activity habits was higher in women and T1DM patients (probably as a consequence of the medical educational intervention). On the contrary, supportiveness of the family in term of changing the undesirable behaviours at home seemed to fail. Conclusions: This study provides first evidence indicating unhealthy dietary behaviours, which could even predispose to the development of diabetes and cardiovascular complications, in subjects living in Pisa. The combination of vitamin B 9 and vitamin E deprivation could be deleterious for endothelial function, since these antioxidants have been implicated in the modulation of nitric oxide and eicosanoid signalling.

“…Comparing the two dietary assessment methods used in the present study, the average level of agreement between the quartiles of absolute nutrient intake was similar to or higher than that reported by studies on Korean (13) , American (14) and German (15) populations. The mean proportion of classification into the same quartile for energy and macronutrients was higher in the present study (40 %) than in the Korean (37 %), American (38 %) and German (32 %) -Adjusted for day-to-day variation in the food diary data.…”

Objective: To assess the validity of a 148-item quantitative FFQ (QFFQ) that was developed for the Barbados National Cancer Study (BNCS) to determine dietary intake over 12 months and examine the dietary risk factors. Design: A cross-sectional validation study of the QFFQ against 4 d food diaries. Spearman's rank correlations (r), intra-class correlation coefficients (ICC) and weighted k were computed as measures of concordance, adjusting for daily variations in the food diaries. Cross-classification tables and Bland-Altman plots were created for further assessment. Setting: BNCS is a case-control study of environmental risk factors for breast and prostate cancer in a predominantly African-origin population in Barbados. Subjects: Fifty-four individuals (21 years and older) were recruited among controls in the BNCS who were frequency-matched on sex and age group to breast and prostate cancer cases. Results: Similar mean daily energy intake was derived from the food diary (8201 kJ (1960 kcal)) and QFFQ (7774 kJ (1858 kcal)). Rho for energy and macronutrients ranged from 0?66 (energy) to 0?17 (dietary fibre). The percentage of energy from carbohydrates and protein showed the highest and lowest ICC among macronutrients (0?63 and 0?27, respectively). The highest weighted k was observed for energy (0?45). When the nutrient intake was divided into quartiles, approximately 34 % of the observations were in the same quartile. Conclusions: This investigation supports the validity of the QFFQ as a method for assessing long-term dietary intake except for dietary fibre, folate, vitamins A, E and B 12 . The instrument will be a useful tool in the analysis of diet-cancer associations in the BNCS. Keywords Quantitative FFQ Food diary Validity Barbados National Cancer StudyThe Barbados National Cancer Study (BNCS) is a populationbased case-control study designed to examine the genetic and environmental risk factors for breast and prostate cancer in a predominantly African-origin population. The importance of nutrition-related factors and growing interest in the role of nutrient-gene interactions in cancer aetiology necessitates the development of a valid method for assessing long-term dietary intake. Studies on the association between diet and cancer have not been performed in Barbados, West Indies, likely due, in part, to the lack of a validated method to assess long-term dietary intake.To fill this gap, a 148-item quantitative FFQ (QFFQ) was developed to determine dietary intake and to examine hypotheses related to diet and its interaction with genes and cancer in African-Barbadians (1) . QFFQ is commonly used in large-scale epidemiological studies and provides a feasible approach to assess the usual long-term dietary intake of a population (2) . Only valid instruments provide correct estimates of diet and diet-cancer associations. Although a gold standard to validate QFFQ currently does not exist, its validity is evaluated by comparing the results of these instruments to those using other dietary assessment methods or ...

“…These participants have been shown to be representative of the general population in terms of BMD and diet,22, 23 and these data have been used in previous studies of dietary exposure and BMD 48. The FFQ used in the current study was previously validated against 24‐hour recalls and was shown to classify over 85% of participants into the same or adjacent quintile of protein intake, demonstrating its ability to rank participants according to their habitual protein intake 49. Furthermore, the FFQ has been shown to be a valid tool to rank participants according to high and low intakes of amino acids, and the correlations with intakes from weighted dietary records are in line with those for other macronutrients 50…”

Although a higher protein intake, particularly from vegetable sources, has been shown to be associated with higher bone mineral density (BMD) the relative impact of specific amino acids on BMD and risk of osteoporosis remains to be determined. Mechanistic research suggests that a number of specific amino acids, including five nonessential amino acids—alanine, arginine, glutamic acid, glycine, and proline—may play a role in bone health, principally through improved production of insulin and insulin‐like growth factor 1 and the synthesis of collagen and muscle protein. However to date, no previous studies have examined the associations between habitual intake of amino acids and direct measures of BMD and prevalence of osteoporosis or osteopenia, and no studies have examined this relationship in discordant identical twin‐pairs. In these analyses of female monozygotic twin‐pairs discordant for amino acid intake (n = 135), twins with higher intakes of alanine and glycine had significantly higher BMD at the spine than their co‐twins with within‐pair differences in spine‐BMD of 0.012 g/cm2 (SE 0.01; p = 0.039) and 0.014 g/cm2 (SE 0.01; p = 0.026), respectively. Furthermore, in cross‐sectional multivariable analyses of 3160 females aged 18 to 79 years, a higher intake of total protein was significantly associated with higher DXA‐measured BMD at the spine (quartile Q4 to quartile Q1: 0.017 g/cm2, SE 0.01, p = 0.035) and forearm (Q4 to Q1: 0.010 g/cm2, SE 0.003, p = 0.002). Intake of six amino acids (alanine, arginine, glutamic acid, leucine, lysine, and proline) were associated with higher BMD at the spine and forearm with the strongest association observed for leucine (Q4 to Q1: 0.024 g/cm2, SE 0.01, p = 0.007). When intakes were stratified by protein source, vegetable or animal, prevalence of osteoporosis or osteopenia was 13% to 19% lower comparing extreme quartiles of vegetable intake for five amino acids (not glutamic acid or proline). These data provide evidence to suggest that intake of protein and several amino acids, including alanine and glycine, may be beneficial for bone health, independent of genetic background. © 2015 The Authors.
