Article Abstract

Scope: The association between a planetary and sustainable EAT-Lancet diet and lung cancer remains inconclusive, with limited exploration of the role of genetic susceptibility and inflammation.

Methods And Results: The study includes 175 214 cancer-free participants in the UK Biobank. Fourteen food components are collected from a 24-h dietary recall questionnaire. A polygenic risk score is constructed through capturing the overall risk variants for lung cancer. Sixteen inflammatory biomarkers are assayed in blood samples. Participants with the highest EAT-Lancet diet scores (≥12) have a lower risk of lung cancer incidence (hazard ratio [HR] = 0.64, 95% confidence interval [CI]: 0.51-0.80) and mortality (HR = 0.65, 95% CI: 0.48-0.88), compared to those with the lowest EAT-Lancet diet scores (≤8). Interestingly, there is a significantly protective trend against both lung adenocarcinoma and lung squamous cell carcinoma with higher EAT-Lancet diet scores. Despite no significant interactions, a risk reduction trend for lung cancer is observed with increasing EAT-Lancet diet scores and decreasing genetic risk. Ten inflammatory biomarkers partially mediate the association between the EAT-Lancet diet and lung cancer risk.

Conclusion: The study depicts a lower risk of lung cancer conferred by the EAT-Lancet diet associated with lower inflammation levels among individuals with diverse genetic predispositions.

Purpose: We developed a diet quality index based on the Planetary Health Diet (PHD) to assess healthy and sustainable diets. The index was applied alongside socio-demographic characteristics in five regions across Europe and North Africa.

Methods: The Sustainable Healthy Diet Index (SHDI) was designed using existing and validated healthy diet indexes.

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).

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.
