Personalized nutrition aims to enhance human health by tailoring dietary recommendations to individuals based on their physiology. This article covers the concept of personalized nutrition using the example of dietary modulation of the human gut microbiome and implications for human health. It provides readers with a basic understanding of multiomics analyses and machine learning tools and how these may be used by nutrition professionals to evaluate studies involving them and personalized nutrition.
Systematically gathering scientific evidence is necessary to build and support safe concepts, treatments, and effective actions for health practice, policies, and recommendations in the field of nutrition. This didactic guide aimed to compile the steps necessary for a methodological systematic review in nutrition through real examples including the mandatory stages of conduct such as preparation of the central question, search strategy, inclusion and exclusion criteria, data collection, extraction of information, and methodological quality analysis of the studies. The article demonstrates that methodological systematic reviews are valuable to track the progress of concepts and practices. In this way, knowledge of the review process is important for the advancement of the field, and reviews are important resources for scientific information due to their synthesis of current evidence.
The Dietary Guidelines for Americans, 2020–2025 was issued jointly by the US Departments of Agriculture and of Health and Human Services in December 2020. It is the ninth edition of the Dietary Guidelines and is the first to provide recommendations by life stage, from birth to older adulthood. The Dietary Guidelines is grounded in the current body of scientific evidence on diet and health outcomes and aims to promote health and prevent chronic diseases. The process to develop the Dietary Guidelines involved 4 steps: (1) identifying the topics and supporting scientific questions, (2) appointing a Dietary Guidelines Advisory Committee (Committee) to review current scientific evidence, (3) developing the new edition of the Dietary Guidelines, and (4) implementing the Dietary Guidelines. The 2020-2025 edition provides 4 overarching guidelines and supporting key recommendations that encourage healthy dietary patterns across the life span. The foods and beverages that people consume have a profound impact on health, and it is never too late or too early to eat healthfully.
Critically ill or immobilized patients are unable to stand for their height to be measured; therefore, knee height measurement is a useful proxy. In order to address this problem, a lot of research has been carried out worldwide to create equations to estimate the stature of adults. However, knee and total height may differ among racial/ethnic groups. This study therefore determined the applicability of equations to estimate stature derived from American and Taiwanese research and then established a new equation from a group of 512 Vietnamese patients aged 18 to 64 years. In this study, 512 patients were divided into 2 groups, the established equation group (n = 400, 214 men and 186 women) and the validated equation group (n = 112, 61 men and 51 women). Based on the linear regression model, the new equation is: body height = 2.12 × knee height + 59.06 (cm) in males and body height = 2.09 × knee height + 57.37 (cm) in females. We calculated the heights of patients based on their knee heights with both equations and then compared the results with their measured standing heights. The results from the American and Taiwanese knee height equations both showed that the difference was statistically significant with a P < .05 between the indirect method of stature estimation with actual body height. In contrast, the new equation was more accurate with a P> .05. Stature estimated from the new knee height equation is suitable for the Vietnamese population in clinical setting.
Neonatal colic is a problem in many young infants. The dietary intakes of women during pregnancy may play an important role in maternal health and fetal development and also in the health of the baby's body system after birth. The aim of this study was to compare maternal food intake during pregnancy in infants with colic and in colic-free infants. We compared reports of food intake during pregnancy of 149 women whose infants had colic with 151 women whose infants did not have colic using a retrospective food frequency questionnaire. Few differences were found in maternal dietary intake of cheese, fish, and poultry during pregnancy (P < .001, P = .002, and P = .011, respectively). In addition, mothers of infants with colic reported eating fewer fruit and vegetables than controls during pregnancy (P = .005 and P < .001, respectively). There was no significant difference between the consumption of fast foods and beverages as well as the type of dairy products and the type of oil consumed by mothers in the 2 groups. Mothers should not blame their pregnancy diet for their infants' colic, but a healthy diet has proven effects on fetal health.
