Association between intake of whole-grain bread (a), coffee (b), cake and cookies (c), and the serum metabolite network of the EPIC-Potsdam subcohort. Presented are partial correlation coefficients adjusted for age, sex, education, alcohol consumption, smoking, physical activity, BMI, waist circumference, prevalent hypertension and prevalent diabetes. Red color implies positive association and blue color inverse association between exposure and metabolite. Intensity of the color reflects the strength of association.
