This study examined the associations of major plant foods, their subtypes and dietary fibre with risk of IHD in the European Prospective Investigation into Cancer and Nutrition (EPIC). Methods We conducted a prospective analysis of 490 311 men and women without a history of myocardial infarction or stroke at recruitment (12.6 years of follow-up, n cases = 8504), in 10 European countries. Dietary intake was assessed using validated questionnaires, calibrated with 24-h recalls. Multivariable Cox regressions were used to estimate hazard ratios (HR) of IHD. Results There was a lower risk of IHD with a higher intake of fruit and vegetables combined [HR per 200 g/day higher intake 0.94, 95% confidence interval (CI): 0.90–0.99, P-trend = 0.009], and with total fruits (per 100 g/day 0.97, 0.95–1.00, P-trend = 0.021). There was no evidence for a reduced risk for fruit subtypes, except for bananas. Risk was lower with higher intakes of nuts and seeds (per 10 g/day 0.90, 0.82–0.98, P-trend = 0.020), total fibre (per 10 g/day 0.91, 0.85–0.98, P-trend = 0.015), fruit and vegetable fibre (per 4 g/day 0.95, 0.91–0.99, P-trend = 0.022) and fruit fibre (per 2 g/day 0.97, 0.95–1.00, P-trend = 0.045). No associations were observed between vegetables, vegetables subtypes, legumes, cereals and IHD risk. Conclusions In this large prospective study, we found some small inverse associations between plant foods and IHD risk, with fruit and vegetables combined being the most strongly inversely associated with risk. Whether these small associations are causal remains unclear. ; UK Research & Innovation (UKRI) Medical Research Council UK (MRC) MR/M012190/1 G0800270 MR/L003120/1 1000143 MC_UU_12015/1 MC_UU_12015/5 MC_UU_12015/520 ; Cancer Research UK C8221/A19170 570/A16491 14136 C570/A16491 ; Wellcome Trust (Our Planet Our Health, Livestock Environment and People) 205212/Z/16/Z ; Cancer Research UK Population Research Fellowship C60192/A28516 ; World Cancer Research Fund (WCRF UK), as part of the Word Cancer Research Fund International grant programme 2019/1953 ; European Commission HEALTH-F2-2012-279233 ; European Research Council (ERC) European Commission 268834 ; British Heart Foundation SP/09/002 RG/08/014 RG13/13/30194 ; National Institute for Health Research (NIHR) ; European Commission LSHM_CT_2006_037197 ; European Commission European Commission Joint Research Centre ; International Agency for Research on Cancer ; Danish Cancer Society ; Ligue Contre le Cancer (France) ; Institut Gustave Roussy (France) ; Mutuelle Generale de l'Education Nationale (France) ; Institut National de la Sante et de la Recherche Medicale (Inserm) ; Deutsche Krebshilfe ; German Cancer Research Center (DKFZ) (Germany) ; Federal Ministry of Education & Research (BMBF) ; Hellenic Health Foundation (Greece) ; Associazione Italiana per la Ricerca sul Cancro (AIRC) ; Consiglio Nazionale delle Ricerche (CNR) ; Dutch Ministry of Public Health, Welfare and Sports (VWS) ; Netherlands Cancer Registry (NKR) ; LK Research Funds ; Dutch Prevention Funds ; Netherlands Organization for Scientific Research (NWO) ; World Cancer Research Fund International (WCRF) ; Instituto de Salud Carlos III PI13/00061 PI13/01162 ; Junta de Andalucia ; Regional Government of Asturias (Spain) ; Regional Government of Basque Country (Spain) ; Regional Government of Murcia (Spain) 6236 ; Regional Government of Navarra (Spain) ; Instituto de Salud Carlos III RD06/0020 ; Swedish Cancer Society ; Swedish Research Council ; County Council of Skane (Sweden) ; County Council of Vasterbotten (Sweden) ; NIHR Biomedical Research Centre Cambridge: Nutrition, Diet, and Lifestyle Research Theme IS-BRC-1215-20014 ; British Heart Foundation ; NIHR Senior Investigator Award ; Girdlers' New Zealand Health Research Council Fellowship ; National Institute for Health Research (NIHR) ; BHF-Turing Cardiovascular Data Science Award ; ECInnovative Medicines Initiative (BigData@Heart) ; Alpro Foundation 15-08-2016 ; Core MRC Unit support through the Nutritional Epidemiology Programme MC_UU_12015/5
