详细说明
In this isocaloric clinical cross-over trial, the investigators aim to investigate if circulating fatty acids and lipids are influenced by alterations in carbohydrate amount and quality.
The investigators intend to evaluate if changes in carbohydrate quantity and quality (including sugar) influence circulating even-chain saturated fatty acids or if fatty acid-derived indices of desaturation and de novo lipogenesis are more sensitive biomarkers of carbohydrate intake.
By performing untargeted lipidomic analyses, the investigators aim to search for novel lipid biomarkers of carbohydrate quantity and quality.
The investigators also want to evaluate the influence of moderate alterations of carbohydrate and sugar intake on lipoproteins, insulin sensitivity, inflammatory proteins.
