Background: It is currently unknown whether plant-based dietary patterns influence disease progression to multimorbidity after an initial non-communicable disease, and whether the associated risk of multimorbidity varies with age. This study aimed to investigate associations of plant-based diets with the risk of multimorbidity, defined as the co-occurrence of at least two chronic diseases in an individual (either cancer at any site, cardiovascular disease, or type 2 diabetes).

Methods: This prospective cohort study used data from EPIC and UK Biobank across six European countries, with participants aged 35-70 years at recruitment.

Background: The role of lipid-perturbing medications in cancer risk is unclear.

Methods: We employed cis-Mendelian randomization and colocalisation to evaluate the role of 5 lipid-perturbing drug targets (ANGPTL3, ANGPTL4, APOC3, CETP, PCSK9) in risk of 5 cancers (breast, colorectal, head and neck, ovarian, prostate). We triangulated findings using pre-diagnostic protein measures in prospective analyses in EPIC (977 colorectal cancer cases, 4,080 sub-cohort members) and the UK Biobank (860 colorectal cancer cases, 50,177 controls).

Background: Significant advancements in treatment and care, as well as early detection, have contributed to an increase in cancer survival rates. Recently, the EAT-Lancet Commission on Food, Planet, Health proposed the "planetary health diet" but to date, no study has investigated the potential associations between adherence to the EAT-Lancet reference diet and mortality in cancer survivors. To determine whether higher adherence to the EAT-Lancet reference diet is associated with lower risk for all-cause, cancer, and cardiovascular mortality in cancer survivors.

Article Synopsis
  • * No significant associations were found between individual metabolites or patterns and overall prostate cancer risk after adjusting for multiple tests, except for six specific phosphatidylcholines linked to advanced cases diagnosed within 10 years.
  • * Two metabolite patterns (1 and 2) showed inverse associations with advanced prostate cancer, while pattern 3 was related to prostate cancer death, indicating that metabolite profiles may change several years before advanced disease is detected.

Article Synopsis
  • The study investigated the links between saturated and unsaturated fatty acids and cardiovascular disease (CVD), focusing on conditions like coronary heart disease (CHD) and stroke in a large group of participants.
  • Results showed that higher levels of saturated fatty acids were linked to increased CVD risks, with specific subtypes having varying effects on CHD and stroke.
  • Conversely, higher concentrations of certain polyunsaturated fatty acids (both n-3 and n-6 types) were associated with lower risks of CHD and stroke, suggesting dietary fats play a significant role in cardiovascular health.

Introduction: The 21-point Brain Care Score (BCS) is a novel tool designed to motivate individuals and care providers to take action to reduce the risk of stroke and dementia by encouraging lifestyle changes. Given that late-life depression is increasingly recognized to share risk factors with stroke and dementia, and is an important clinical endpoint for brain health, we tested the hypothesis that a higher BCS is associated with a reduced incidence of future depression. Additionally, we examined its association with a brain health composite outcome comprising stroke, dementia, and late-life depression.

Background: The associations of vegetarian diets with risks for site-specific cancers have not been estimated reliably due to the low number of vegetarians in previous studies. Therefore, the Cancer Risk in Vegetarians Consortium was established. The aim is to describe and compare the baseline characteristics between non-vegetarian and vegetarian diet groups and between the collaborating studies.

Advanced glycation end-products (AGEs), formed endogenously or obtained exogenously from diet, may contribute to chronic inflammation, intracellular signaling alterations, and pathogenesis of several chronic diseases including colorectal cancer (CRC). However, the role of AGEs in CRC survival is less known. The associations of pre-diagnostic circulating AGEs and their soluble receptor (sRAGE) with CRC-specific and overall mortality were estimated using multivariable-adjusted Cox proportional hazards regression among 1369 CRC cases in the European Prospective Investigation into Cancer and Nutrition (EPIC) study.

Article Synopsis
  • There is uncertainty about the adequacy of contemporary plant-based diets in meeting essential nutrient intakes, leading to the establishment of the Feeding the Future (FEED) study in the UK.
  • The study involved 6,342 participants across various diet groups (omnivores, flexitarians, pescatarians, vegetarians, and vegans), assessing their diets through food frequency questionnaires.
  • Findings revealed that while most participants met UK recommendations for certain nutrients, vegetarians and vegans often had lower protein and certain vitamins, indicating a need for better dietary choices or food fortification to prevent nutrient deficiencies.
