Metabolites associated with dietary intake frequencies (weekly). Weekly dietary frequency intake data of the 11 main food groups (cereal, meat, fish, dairy, lipids, potatoes, vegetables, fruits, sweets, bakery products, beverages) were collected via food frequency questionnaire, and multiple linear regression analysis followed by meta-analysis were performed on each metabolite—dietary factor pair. Regression models were adjusted for analytical batching, postprandial effect (for serum), sampling (urine), age, sex and zBMI score
