Cohort studies do not suggest a clear benefit of higher intake of polyunsaturated fatty acids but, in contrast, higher circulating linoleic acid (LA) levels-reflective of dietary LA intake, are associated with a reduced risk of type 2 diabetes. However, genetic variants in the fatty acid desaturase 1 gene (FADS1) may influence individual responses to plant-based fats. We explored whether FADS1 variants influence the relationships of LA and α-linolenic acid (ALA) intakes and nut consumption with plasma phospholipid fatty acid profiles and type 2 diabetes risk in a large-scale cohort study and a randomized controlled trial.In the EPIC-InterAct case-cohort (7,498 type 2 diabetes cases, 10,087 subcohort participants), we investigated interactions of dietary and plasma phospholipid fatty acids and nut consumption with FADS1 rs174547 in relation to incident type 2 diabetes using weighted Cox regression. In PREDIMED (492 participants in the Mediterranean Diet + Nuts intervention group, 436 participants in the control group), we compared changes in plasma phospholipid FAs from baseline to year 1.In EPIC-InterAct and PREDIMED, nut consumption was positively associated with LA plasma levels and inversely with arachidonic acid, the latter becoming stronger with increasing number of the minor rs174547 C allele (p interaction EPIC-InterAct: 0.030, PREDIMED: 0.003). Although the inverse association of nut consumption with diabetes seemed stronger in participants with rs174547 CC-genotype (HR: 0.73, 95% CI: 0.54-1.00) compared with CT (0.94, 0.81-1.10) or TT (0.90, 0.78-1.05) in EPIC-InterAct, this interaction was not statistically significant.FADS1 variation modified the effect of nut consumption on circulating FAs. We did not observe clear evidence that it modified the association between nut consumption and type 2 diabetes risk. 000301905 536__ $$0G:(DE-HGF)POF4-313$$a313 - Krebsrisikofaktoren und Prävention (POF4-313)$$cPOF4-313$$fPOF IV$$x0 000301905 588__ $$aDataset connected to CrossRef, PubMed, , Journals: inrepo02.dkfz.de 000301905 650_7 $$2Other$$aCohort study 000301905 650_7 $$2Other$$aFatty acid desaturase 000301905 650_7 $$2Other$$aPlasma phospholipid fatty acids 000301905 650_7 $$2Other$$aPolyunsaturated fatty acids 000301905 650_7 $$2Other$$aRandomized controlled trial 000301905 650_7 $$0EC 1.14.19.-$$2NLM Chemicals$$aFatty Acid Desaturases 000301905 650_7 $$2NLM Chemicals$$aDelta-5 Fatty Acid Desaturase 000301905 650_7 $$0EC 1.14.19.3$$2NLM Chemicals$$aFADS1 protein, human 000301905 650_7 $$00RBV727H71$$2NLM Chemicals$$aalpha-Linolenic Acid 000301905 650_7 $$09KJL21T0QJ$$2NLM Chemicals$$aLinoleic Acid 000301905 650_7 $$2NLM Chemicals$$aFatty Acids 000301905 650_2 $$2MeSH$$aHumans 000301905 650_2 $$2MeSH$$aDiabetes Mellitus, Type 2: genetics 000301905 650_2 $$2MeSH$$aDiabetes Mellitus, Type 2: blood 000301905 650_2 $$2MeSH$$aDiabetes Mellitus, Type 2: epidemiology 000301905 650_2 $$2MeSH$$aFatty Acid Desaturases: genetics 000301905 650_2 $$2MeSH$$aDelta-5 Fatty Acid Desaturase 000301905 650_2 $$2MeSH$$aalpha-Linolenic Acid: administration & dosage 000301905 650_2 $$2MeSH$$aMale 000301905 650_2 $$2MeSH$$aFemale 000301905 650_2 $$2MeSH$$aLinoleic Acid: administration & dosage 000301905 650_2 $$2MeSH$$aLinoleic Acid: blood 000301905 650_2 $$2MeSH$$aMiddle Aged 000301905 650_2 $$2MeSH$$aAged 000301905 650_2 $$2MeSH$$aNuts 000301905 650_2 $$2MeSH$$aFatty Acids: blood 000301905 650_2 $$2MeSH$$aCohort Studies 000301905 650_2 $$2MeSH$$aPolymorphism, Single Nucleotide 000301905 650_2 $$2MeSH$$aRisk Factors 000301905 7001_ $$aKuxhaus, Olga$$b1 000301905 7001_ $$aPrada, Marcela$$b2 000301905 7001_ $$aHuybrechts, Inge$$b3 000301905 7001_ $$aTong, Tammy Y N$$b4 000301905 7001_ $$aForouhi, Nita G$$b5 000301905 7001_ $$aRazquin, Cristina$$b6 000301905 7001_ $$aCorella, Dolores$$b7 000301905 7001_ $$aMartinez-Gonzalez, Miguel A$$b8 000301905 7001_ $$aDahm, Christina C$$b9 000301905 7001_ $$aIbsen, Daniel B$$b10 000301905 7001_ $$aTjønneland, Anne$$b11 000301905 7001_ $$aHalkjær, Jytte$$b12 000301905 7001_ $$aMarques, Chloé$$b13 000301905 7001_ $$aCadeau, Claire$$b14 000301905 7001_ $$aRen, Xuan$$b15 000301905 7001_ $$0P:(DE-He78)fb68a9386399d72d84f7f34cfc6048b4$$aKatzke, Verena$$b16$$udkfz 000301905 7001_ $$aBendinelli, Benedetta$$b17 000301905 7001_ $$aAgnoli, Claudia$$b18 000301905 7001_ $$aCatalano, Alberto$$b19 000301905 7001_ $$aFarràs, Marta$$b20 000301905 7001_ $$aSánchez, Maria-Jose$$b21 000301905 7001_ $$aLópez, María Dolores Chirlaque$$b22 000301905 7001_ $$aGuevara, Marcela$$b23 000301905 7001_ $$aAune, Dagfinn$$b24 000301905 7001_ $$aSharp, Stephen J$$b25 000301905 7001_ $$aWareham, Nicholas J$$b26 000301905 7001_ $$aSchulze, Matthias B$$b27 000301905 773__ $$0PERI:(DE-600)2131669-7$$a10.1186/s12916-025-04187-8$$gVol. 23, no. 1, p. 344$$n1$$p344$$tBMC medicine$$v23$$x1741-7015$$y2025 000301905 909CO $$ooai:inrepo02.dkfz.de:301905$$pVDB 000301905 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)fb68a9386399d72d84f7f34cfc6048b4$$aDeutsches Krebsforschungszentrum$$b16$$kDKFZ 000301905 9131_ $$0G:(DE-HGF)POF4-313$$1G:(DE-HGF)POF4-310$$2G:(DE-HGF)POF4-300$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lKrebsforschung$$vKrebsrisikofaktoren und Prävention$$x0 000301905 9141_ $$y2025 000301905 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bBMC MED : 2022$$d2024-12-05 000301905 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2024-12-05 000301905 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2024-12-05 000301905 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal$$d2024-04-10T15:34:47Z 000301905 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ$$d2024-04-10T15:34:47Z 000301905 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Open peer review$$d2024-04-10T15:34:47Z 000301905 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2024-12-05 000301905 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2024-12-05 000301905 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2024-12-05 000301905 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews$$d2024-12-05 000301905 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2024-12-05 000301905 915__ $$0StatID:(DE-HGF)1190$$2StatID$$aDBCoverage$$bBiological Abstracts$$d2024-12-05 000301905 915__ $$0StatID:(DE-HGF)1110$$2StatID$$aDBCoverage$$bCurrent Contents -
