While TRE is known to induce health benefits, particularly for adults with obesity, there is currently debate about whether the time of day in which food is consumed also contributes to the health benefits of TRE. Early TRE (eTRE) and late TRE (lTRE) are subtypes of TRE that involve consuming food and caloric beverages either in the early or later part of the day. A growing body of literature indicates that eTRE may offer additional health benefits compared with lTRE. An important and unanswered question, however, is whether most adults can adhere to this type of eating pattern and whether adherence and retention differ between eTRE and lTRE. This narrative review compared adherence and retention in studies that implemented either eTRE or lTRE in adults for 8 weeks or longer. Five databases were searched, and 10 studies met our eligibility criteria. The key finding was that participants had high and comparable levels of adherence and retention in both eTRE and lTRE interventions. Specifically, the mean adherence rate was 81.4% for eTRE and 82.3% for lTRE, while the mean retention rate was 81% for eTRE and 85.8% for lTRE in eligible studies. Thus, the findings support the feasibility of both approaches. The lowest adherence and retention rates occurred in studies in which either eTRE or lTRE regimens were combined with other dietary interventions. Notably, the duration of the eating window did not seem to negatively affect adherence and retention rates for either eTRE or lTRE.

Within this scenario, there is a known interaction between vitamin A and iron, and it has been postulated that lack of vitamin A impairs iron metabolism, leading to vitamin A deficiency anemia (VADA). Current animal, epidemiological, and clinical studies support this notion. The objective of this study was to review the current literature on proposed metabolic mechanisms regarding how VAD modulates iron metabolism leading to anemia. To attain this objective, a literature search was conducted of research publications in the related field, without date restriction, using PubMed, Scopus, Google Scholar, and the University of Illinois's reference system. The data support the essentiality of vitamin A for normal erythropoiesis. It indicates that, in VAD, iron mobilization is impaired, and that this mineral accumulates in the liver and spleen, making it less available for erythropoiesis. A triggering factor for the development of VADA seems to be inflammation and systemic infection, which release cytokines that upregulate the production of hepcidin by the liver. VAD may also increase hepcidin directly without the involvement of inflammation or infection. The elevated hepcidin, in turn, lowers circulating iron and sequesters iron in storage depots, downregulating erythropoietin, leading to inefficient erythropoiesis, decreased hemoglobin (Hb) production, and (subsequently) anemia. VAD may also impact the expression of iron regulatory protein 2 (IRP2), and thus affect intracellular iron metabolism gene expression. VADA is not due to iron deficiency, but to a redistribution of iron in the body. Understanding the mechanism of VADA will assist in designing more effective strategies for combating anemia worldwide.</p>","PeriodicalId":19469,"journal":{"name":"Nutrition reviews","volume":" ","pages":""},"PeriodicalIF":5.9,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142818795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
