Abstract

This study was conducted to investigate whether or not a food substitute (Dr. BAANs(R)) containing three bioactive components L-arginine, omega-3 polyunsaturated fatty acid, and ribonucleic acid, supplied orally to 15 overweight patients, may have efficacy to prevent or improve the metabolic syndrome of these patients. To provide supporting data for this clinical study, the in vivo fatty acid metabolism of obese mice was analyzed using (125)I labeled 15-(p-iodophenyl)-9-methylpentadecanoic acid (9MPA) in the tissues' lipid pool. After 3 months of intervention, the results showed that there were improvements observed in liver functions, lipid profiles and metabolic syndrome marker. Significant differences were also found in the values of blood pressure, body weight, percentage of body fat, and body mass index. In the animal study, the tissue uptake of (125)I-9MPA at 10 min after injection was higher in obese mice than in the control mice and the treatment with Dr. BAANs(R) in obese mice decreased the uptake significantly. The final product metabolite of p-iodophenylacetic acid in obese mice was increased significantly by the treatment. In conclusion, this food substitute may have a beneficial effect for the prevention or improvement of metabolic syndrome.
