A comparative analysis of heme vs non-heme iron administration: a systematic review and meta-analysis of randomized controlled trials.

Background And Purpose: Bioavailability studies and observational evidence suggest that heme iron (HI) may have greater impact on iron status indicators compared with non-heme iron (NHI). This systematic review and meta-analysis aimed to review the current evidence on the effect of the administration of HI compared with NHI for improving iron status in non-hospitalized population groups.

Methods: We searched Pubmed, CENTRAL, Scopus, Web of Science, and LILACS from inception to July 2024.

Ultra-processed foods consumption and health-related outcomes: a systematic review of randomized controlled trials.

Introduction: The increase in ultra-processed foods (UPFs) intake has raised concerns about its impact on public health. Prospective observational studies have reported significant associations between higher intake of UPFs and adverse health outcomes. The aim of this study is to determine whether these associations could be confirmed in randomized controlled trials (RCTs).

Effect of reducing saturated fat intake on cardiovascular disease in adults: an umbrella review.

Introduction: Our objective was to explore the effect of the reduction of saturated fat (SAF) intake on cardiovascular disease, mortality and other health-related outcomes in adults.

Methods: We conducted an umbrella review, searching Medline, Scopus, EMBASE, Cochrane Library, and LILACS databases for systematic reviews from December 1, 2012, to December 1, 2022. We have included meta-analyses of randomized controlled trials (RCTs) and cohort studies.

Objectives: Synthesize available information on the effects of front-of-package nutritional labeling on choice, purchase, and consumption of food and beverages, and nutritional status of consumers, and identify factors that influence its effectiveness.

Methods: A synopsis of systematic reviews was carried out following PRISMA recommendations. A literature search was performed in MEDLINE (PubMed), Cochrane Library, LILACS, EBSCOhost, and Scopus, limited to studies published in Spanish or English with no restrictions on date of publication.

[Interventions to prevent the development of overweight and obesity in children younger than five years].

Childhood obesity is one of the most severe public health problems worldwide. The present study describes the interventions used to prevent overweight and obesity in children younger than 5 years. The objective of the interventions was to stimulate breastfeeding, monitor the child's growth, and promote adequate complementary feeding by means of nutritional counseling using a responsive feeding approach in different settings, including health centers and residences.

[Rice fortification to correct micronutrient deficiency in children 6-59 months old].

Objective: To carry out a systematic review of the literature on the effectiveness of fortified rice consumption in terms of increasing levels of iron and other micro-nutrients in children aged 6-59 months, with a view to evaluating its usefulness as a public health intervention.

Methods: A search was conducted in MEDLINE, Embase, Cochrane Library, and LILACS databases. The review included randomized clinical trials (RCTs) that assessed the consumption of fortified rice, compared with a placebo or other forms of intervention, in terms of enhanced levels of iron and other micronutrients.

[State of the quality of drinking water in households in children under five years in Peru, 2007-2010].

Objective: To evaluate the proportion of children under five with access to quality water and its behavior according to geographical location, water supply and poverty status.
