Coefficients for the metabolites selected ten times in the 10-CV elastic net for legume consumption. Mean and SD of the set of the metabolites selected ten times in the ten times iterated tenfold-cross validation of the elastic continuous regression procedure (using lambda.min) employing the whole dataset of subjects (n = 1833). Metabolites with negative coefficients (n = 22) are plotted in A, whereas those with positive coefficients (n = 18) are shown in B. DAG diacylglycerol, GABA γ-aminobutyric acid, LPC lysophosphatidylcholine, MAG monoacylglycerol, PC phosphatidylcholine, PE phosphatidylethanolamine, SM Sphingomyelin, TG triacylglycerol
