Context: The EAT-Lancet planetary health diet represents a dietary pattern designed to optimize human health and the environmental health of the planet. Although the potential impact of nutrition on cancer patients has gained increasing attention, research specifically examining the association between the EAT-Lancet diet and cancer outcomes remains limited.
Objective: This study aimed to prospectively evaluate the association between adherence to the EAT-Lancet diet and cancer risk, with a particular focus on cancer incidence and mortality rates.
Data Sources: A comprehensive literature search was performed across multiple databases, including PubMed, MEDLINE, Embase, Cochrane, and EBSCO.
Data Extraction: First author and year, country, study design, sample, mean age, questionnaires, cancer type, duration of follow-up, and main findings were extracted from the original articles by 2 reviewers independently. Random-effects models were used, and statistical heterogeneity was evaluated by using the I2 statistic. This systematic review following the updated Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines.
Data Analysis: The meta-analysis incorporated 8 high-quality cohort studies, encompassing 1 103 953 participants. The findings demonstrated that adherence to the EAT-Lancet diet was associated with reduced cancer incidence (HR = 0.78, 95%CI: 0.65, 0.93; P = .006) and cancer mortality (HR = 0.93, 95% CI: 0.89, 0.98; P = .005).
Conclusion: This study provides potential evidence that following the EAT-Lancet diet is significantly associated with reduced cancer incidence and mortality. These findings underscore the clinical importance and potential health benefits of adopting this dietary pattern to improve the quality of life of cancer patients. However, given the limited number of available studies, further high-quality research is warranted to comprehensively understand the relationship between the EAT-Lancet diet and cancer outcomes.
Systematic Review Registration: PROSPERO registration No. CRD42024520028.

The planetary health diet (PHD) proposed by the EAT-Lancet Commission, advocates for reduced meat and dairy intake while emphasizing the consumption of whole grains, fruits, vegetables, nuts, and legumes. Existing studies have shown that the PHD can lower mortality rates and slow cognitive decline in various populations. However, its specific effects on cognitive impairment among elderly individuals in China remain unclear, primarily due to regional socioeconomic and cultural differences.

Background: Sub-Saharan Africa is facing a dietary transition with both undernutrition and rising rates of non-communicable diseases. Adopting the reference diet proposed by the EAT-Lancet Commission can reduce both the environmental burden and improve health outcomes. However, whether this diet provides micronutrient adequacy in older adults in low-income settings has not been investigated.

Objective: (1) To evaluate the quality and perception of the diet, as well as the dietary diversity (DD) of the students of the bachelor's degree in nutrition in Argentina; (2) estimate the water footprint (WF) associated with their food consumption; (3) compare the total dietary WF of the participants with proposed recommendations, and (4) compare the scores of quality, DD, and dietary WF volume between students' groups according to their academic progress.
Design: An observational and descriptive study with a cross-sectional quantitative design was conducted in June 2022.
Participants: Five hundred and twenty-five students (207 entrants and 318 advanced).

Background: No study has been conducted to investigate the association between adherence to the EAT-Lancet diet and odds of irritable bowel syndrome (IBS) and functional dyspepsia (FD). This cross-sectional study was aimed to assess the association between adherence to the EAT-Lancet diet and odds of IBS and FD.
Methods: This cross-sectional analysis was done among 1892 Iranian apparently healthy adults, aged 18 to 65 years, in Isfahan, Iran.
