“…Speed skaters and short-track skaters had mean creatinine levels of approximately 14•5 mmol/d. The middledistance runners, Paralympic cyclist, track cycling sprinters, athletic sprinters and archers had slightly higher mean creatinine levels of approximately 20 mmol/d (range [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. In addition, BMX riders had the highest creatinine levels in comparison with others (average approximately 24 mmol/d, with a range of 19-32 mmol/d).…”

“…Urinary N as marker for dietary protein as proposed by Isaksson (19) is well accepted as a marker for actual protein intake (13,14,(16)(17)(18) , but assumes N balance. Especially in athletes, this assumption may not always be applicable because athletes potentially have a higher protein turnover than more sedentary subjects (49) .…”

“…Validation studies are important for identifying the magnitude and type of measurement error of a specific method. For validation purposes, 24-h urinary N is considered the best available biomarker to estimate dietary protein intake (13)(14)(15)(16)(17)(18) . The method was first proposed by Isaksson (19) and further developed by Bingham & Cummings (15) .…”

Information on dietary composition is vitally important for elite athletes to optimise their performance and recovery, which requires valid tools. The aim of the present study was to investigate the validity of assessing protein intake using three web-based 24-h recalls and questionnaires, by comparing these with three urinary N excretions on the same day. A total of forty-seven Dutch elite top athletes, both disabled and non-disabled, aged between 18 and 35 years, with a BMI of 17·5-31 kg/m 2 , exercising >12 h/week were recruited. Estimated mean dietary protein intake was 109·6 (SD 33·0) g/d by recalls and questionnaires v. 141·3 (SD 38·2) g/d based on N excretions in urine; the difference was 25·5 (SD 21·3) % between the methods (P < 0·05). We found a reasonably good association between methods for protein intake of 0·65 (95 % CI 0·45, 0·79). On an individual level, under-reporting was larger with higher protein intakes than with lower intakes. No significant differences were found in reporting absolute differences between subcategories (sex, under-reporting, BMI, collection of recalls within a certain amount of time and using protein supplements or not). In conclusion, combined, multiple, 24-h recalls and questionnaires underestimated protein intake in these young elite athletes more than that reported for non-athlete populations. The method proved to be suitable for ranking athletes according to their protein intake as needed in epidemiological studies. On an individual level, the magnitude of underestimation was about equal for all athletes except for those with very high protein intakes.

“…In contrast, repetitive 24 h dietary recalls for twenty-four homeless individuals in Sheffield found that vitamin B 6 and niacin exceeded the recommended nutrient intake levels (5) , a finding which has also been reported in a study using 48 h dietary recall for ninety-seven homeless men in Paris (10) . The potential for bias similar to that found for the FFQ (30,31) in conjunction with the presence of under-reporting (32,33) and over-reporting (34,35) highlight limitations associated with the sole use of 24 h recall for assessing the nutritional status of the homeless.

Nutrition and the homeless: the underestimated challenge

2016

Homelessness is present in most societies and represents a situation in which the basic needs for survival including food are often limited. It is logical to surmise that the homeless person's diet is likely to be nutritionally deficient and yet there is a relative paucity in research regarding this issue with studies varying in both their methodology and homeless population. Despite these differences, diets of the homeless are frequently characterised as high in saturated fat and deficient in fibre and certain micronutrients, all of which can have negative implications for the homeless individual's health and/or mental state. The conclusion from intervention studies is that there is no consensus as to the most effective method for assessing dietary intake. In order to address this, the present review aims to provide a greater understanding of the existing literature surrounding nutrition and the homeless and to act as a foundation from which further research can be conducted. An evaluation of the main findings and challenges surrounding the assessment of the nutritional status of the homeless will be provided followed by a review of the physical and mental consequences of the homeless diet. Current and potential interventions aimed at increasing the nutritional quality of food consumed by the homeless will be addressed with a focus on the role of the nutritional science community in assisting in this endeavour.

BackgroundDietary sodium and potassium are involved in the pathogenesis of cardiovascular disease. Data exploring the cardiovascular outcomes associated with these electrolytes within Australian children is sparse. Furthermore, an objective measure of sodium and potassium intake within this group is lacking.ObjectiveThe primary aim of the Salt and Other Nutrient Intakes in Children (“SONIC”) study was to measure sodium and potassium intakes in a sample of primary schoolchildren located in Victoria, Australia, using 24-hour urine collections. Secondary aims were to identify the dietary sources of sodium and potassium, examine the association between these electrolytes and cardiovascular risk factors, and assess children’s taste preferences and saltiness perception of manufactured foods.MethodsA cross-sectional study was conducted in a convenience sample of schoolchildren attending primary schools in Victoria, Australia. Participants completed one 24-hour urine collection, which was analyzed for sodium, potassium, and creatinine. Completeness of collections was assessed using collection time, total volume, and urinary creatinine. One 24-hour dietary recall was completed to assess dietary intake. Other data collected included blood pressure, body weight, height, waist and hip circumference. Children were also presented with high and low sodium variants of food products and asked to discriminate salt level and choose their preferred variant. Parents provided demographic information and information on use of discretionary salt. Descriptive statistics will be used to describe sodium and potassium intakes. Linear and logistic regression models with clustered robust standard errors will be used to assess the association between electrolyte intake and health outcomes (blood pressure and body mass index/BMI z-score and waist circumference) and to assess differences in taste preference and discrimination between high and low sodium foods, and correlations between preference, sodium intake, and covariates.ResultsA total of 780 children across 43 schools participated. The results from this study are expected at the end of 2015.ConclusionsThis study will provide the first objective measure of sodium and potassium intake in Australian schoolchildren and improve our understanding of the relationship of these electrolytes to cardiovascular risk factors. Furthermore, this study will provide insight into child taste preferences and explore related factors. Given the cardiovascular implications of consuming too much sodium and too little potassium, monitoring of these nutrients during childhood is an important public health initiative.
