The vitamin (B1, B2, B6, retinol, beta-carotene, E and ascorbic acid) status of 56 young women (aged 21-30 years) has been analysed by studying dietary intakes and biochemical parameters and relating them to energy intake. Only 25% of the sample consumed more than 2000 kcal/day and a high percentage of apparently healthy women had low vitamin intakes, especially in the case of vitamin E, B6 and retinol. Except for retinol and beta-carotene, significant correlations between energy and vitamin intakes were found. With respect to blood levels, 86% of women had deficient or marginal levels for B1, 71% for B2, 75% for B6 and 64% for beta-carotene. An adequate or optimal situation has been shown in the case of vitamin C (92%), E (88%) and retinol (77.5%). No correlation between energy intake and vitamin blood levels was found, except for vitamin B6. These data show that young women are vulnerable to developing vitamin deficiencies, especially those consuming low energy diets.

The purpose of the present narrative review was to propose a unifying generalized conceptual model of mechanisms and processes in appetite self-regulation (ASR) in childhood. Appetite self-regulation, along with other domains of self-regulation, develops across childhood and contributes to energy intake and balance, diet quality, weight, and therefore long-term health outcomes. There have been efforts to conceptualize and measure components of ASR and associated processes/mechanisms, but, at present, there is no unifying conceptualization of ASR in childhood.

Background: As a state of metabolic and nutritional derangements, protein-energy wasting (PEW) is highly prevalent and associated with increased morbidity and mortality in hemodialysis patients. Fibroblast growth factor-23 (FGF-23) and Klotho have been proven to contribute to chronic kidney disease-mineral and bone disorder (CKD-MBD) in patients undergoing hemodialysis. Previous evidence suggested that FGF-23 and Klotho may also contribute to the malnutritional status among these patients; however, the inter-relationship between the FGF-23-Klotho axis and PEW remains unclear.

Background: Osteoporosis is a chronic condition characterized by reduced bone strength and an elevated risk of fractures. The influence of diet and glucose metabolism on bone health and the development of osteoporosis has been an area of interest. This study aimed to investigate the potential association between dietary glycemic index (DGI), dietary glycemic load (DGL), dietary insulin index (DII), dietary insulin load (DIL), and the odds of osteoporosis among Iranian adults.

Fragility fractures of the hip are a common injury in England. Meeting post-operative resting energy expenditure (REE) needs are fundamental to recovery from trauma that with greater nutritional intake, post-operative complications and length of stay can be reduced. However, dietary intake can be overlooked when the goal is prompt surgery to reduce pain and lower the risks of mortality at 30 days and 1 year.

Background: The growth in obesity and rates of abdominal obesity in developing countries is due to the dietary transition, meaning a shift from traditional, fiber-rich diets to Westernized diets high in processed foods, sugars, and unhealthy fats. Environmental changes, such as improving the quality of dietary fat consumed, may be useful in preventing or mitigating the obesity or unhealthy obesity phenotype in individuals with a genetic predisposition, although this has not yet been confirmed. Therefore, in this study, we investigated how dietary fat quality indices with metabolically healthy obesity (MHO) or metabolically unhealthy obesity (MUO) based on the Karelis criterion interact with genetic susceptibility in Iranian female adults.
