Biomarkers of Processed Meat Intake
Intervention Study to Identify Biomarkers of Processed Meat Intake
調査の概要
状態
詳細な説明
The intake of processed meat has been linked to several adverse health outcomes such as cancer. However, little is known about the respective effects of the single products in this diverse group.
Most epidemiological studies rely on self-reported questionnaires to assess the intake of different foods. Even though this method is relatively easy to perform, it is prone to errors such as memory biases of subjects or difficulties in estimating portion size. The use of food specific biomarkers may overcome this limitation by offering an objective quantification of dietary exposure. No biomarkers for the consumption of processed meat products have been established yet.
Twelve human healthy adults will participate in a randomized cross-over dietary intervention study and will consume three different processed meat products, fresh meat or no meat, each during 3 successive days followed by a 10-day washout period. The metabolite profile in urine and plasma samples will be analysed to find metabolites that are specific for the intake of the processed meat products.
The identification of these biomarkers in blood and urine will allow a more precise estimation of intake of different processed meat products. This will enable a more robust estimation of the risk linked to the intake of processed meat products.
