The number of people suffering from Type 2 Diabetes (T2DM) has increased dramatically. T2DM is a multifactorial disease
accompanied by abnormalities in lipid metabolism. Omega-3 fatty acids and vegetables have been shown to improve the
health status in patients with T2DM. Metabolomics have provided opportunity to explore global metabolic status after a given
intervention instead of just looking at few metabolic factors. In first stage of our study, 20 subjects with T2DM were randomly
assigned into the control- or intervention group. All subjects received information about the potentials of a healthy diet and
intervention group, additionally received 25 g of walnut oil and 300 g of vegetables daily during eight weeks. Using a stat of
art LC-MS/MS metabolomics 485 metabolites were measured quantitavely in plasma of subjects at baseline and at the end
of intervention. Multivariate data analysis using MLPLS-DA showed that 25 g oil and 300 g of vegetable causes a significant
reduction in prostaglandin F2α (PGF2α), phospholipids and ceramides. Both phospholipids and ceramides are increased in
T2DM and their reduction in our study could be explained by the reduction of PGF2α by omega3 fatty acids in walnut oil. The
results were investigated in another cohort of T2DP (n=25).
