| Title: | Changes in Plasma Acylcarnitine and Lysophosphatidylcholine Levels Following a High-Fructose Diet: A Targeted Metabolomics Study in Healthy Women. |
| Abstract: | BACKGROUND: The consumption of high amounts of fructose is associated with metabolic diseases. However, the underlying mechanisms are largely unknown. OBJECTIVE: To determine the effects of high fructose intake on plasma metabolomics. STUDY DESIGN: We enrolled 12 healthy volunteers (six lean and six obese women, age 24⁻35 years) in a crossover intervention study. All participants carried out three diets: (1) low fructose (<10 g/day); (2) high fructose (100 g/day) from natural food sources (fruit); and (3) high fructose (100 g/day) from high fructose syrup (HFS). OUTCOME MEASURES: The primary outcome was changes in plasma metabolites measured by targeted metabolomics. RESULTS: High compared to low fructose diets caused a marked metabolite class separation, especially because of changes in acylcarnitine and lysophosphatidylcholine levels. Both high fructose diets resulted in a decrease in mean acylcarnitine levels in all subjects, and an increase in mean lysophosphatidylcholine and diacyl-phosphatidylcholine levels in obese individuals. Medium chain acylcarnitines were negatively correlated with serum levels of liver enzymes and with the fatty liver index. DISCUSSION: The metabolic shifts induced by high fructose consumption suggest an inhibition of mitochondrial β-oxidation and an increase in lipid peroxidation. The effects tended to be more pronounced following the HFS than the fruit diet. |
