Out of the 18 Bonferroni-significant CpGs, methylation levels corresponding to higher diet quality were associated with lower C-reactive protein levels (six CpGs), lower BMI (six CpGs), lower waist circumference (two CpGs), lower risk of T2D (three CpGs), lower triglycerides (one CpG), higher HDL cholesterol (one CpG), lower SBP (one CpG), lower carotid intima–media thickness (one CpG), lower risk of myocardial infarction (one CpG), better lung function (two CpGs), and lower risk of Crohn’s disease (two CpGs). Here, CRP is linked to type 2 diabetes mellitus.
