Assessing food intake of pregnant women is extremely important, because maternal dietary patterns can influence fetal development as well as have either positive or negative effects on both the mother and fetus. Thus, the aim of the present study was to carry out a systematic review of the literature on food frequency questionnaires developed and validated for pregnant women, in order to assess their methodological quality and validation process. ⋯ Food frequency questionnaires developed for pregnant women appear to be reliable tools to assess food intake by this group. Overall, they had good methodological quality and adequate correlation coefficients compared with reference methods.

Nutrigenetics and nutrigenomics, combined with the omics technologies, are a demanding and an increasingly important field in personalizing nutrition-based care to understand an individual's response to nutrition-guided therapy. Omics is defined as the analysis of the large data sets of the biological system featuring transcriptomics, proteomics, and metabolomics and providing new insights into cell regulation. The effect of combining nutrigenetics and nutrigenomics with omics will give insight into molecular analysis, as human nutrition requirements vary per individual. ⋯ Although dietary-based therapies are provided for various clinical conditions such as inborn errors of metabolism, limited advancement has been done to expand the omics data for a more mechanistic understanding of cellular networks dependent on nutrition-based expression and overall regulation of genes. The greatest challenge remains in the clinical sector to integrate the current data available, overcome the well-established limits of self-reported methods in research, and provide omics data, combined with nutrigenetics and nutrigenomics research, for each individual. Hence, the future seems promising if a design for personalized, nutrition-based diagnosis and care can be implemented practically in the health care sector.

Randomized Controlled Trial
The effect of β-hydroxy β-methylbutyrate (HMB) with nutritional counselling on anthropometric muscle mass markers, strength, functionality, and quality of life in patients on the waiting list for liver transplantation: A double-blind study.
Patients on the waiting list for liver transplantation (LTx) usually lose muscle mass. Supplementation with β-hydroxy β-methylbutyrate (HMB) may have a promising effect on this clinical condition. This study aimed to evaluate the effects of HMB on muscle mass, strength, functionality, and quality of life in patients on the LTx waiting list. ⋯ Nutritional counselling with supplementation with HMB or active control in patients on the LTx waiting list improved AC, dynamometry, and the FI in both groups.

The aim of this study was to investigate the involvement of Brazilian adolescents in home cooking, estimating its associations with sex and socioeconomic status. ⋯ We verified an alarming prevalence of adolescents with behaviors unaligned with Brazilian Food Guide recommendations; that is, most of them, especially boys, were not involved in home cooking. Adolescence may present a window of opportunity for the development of culinary skills, resulting in long-term benefits for the population's diet quality. Furthermore, to change a historical pattern that overloads women's daily lives, it is necessary to encourage, from an early age, the presence of boys in the kitchen.

This study aimed to examine the relationship between mindful eating and diet quality among adults in Turkey. ⋯ Developing mindful eating might be helpful for individual health promotion and quality of life by providing improvements in diet quality of adults.
