Elevated levels of triglyceride and triglyceride-rich lipoprotein triglyceride induced by a high-carbohydrate diet is associated with polymorphisms of APOA5-1131T > C and APOC3-482C > T in Chinese healthy young adults.

摘要

Background/Aims: Changes in lipid profiles have been shown to be associated with diet and apolipoprotein (APO) polymorphisms. Therefore, 2 polymorphisms, i.e. APOA5-1131T > C and APOC3-482C > T, and serum lipids were examined in a Chinese healthy young population with high-carbohydrate/low-fat (HC/LF) diet intervention. Methods: After a wash-out diet for 7 days, 56 young adults (22.89+or-1.80 years) received the HC/LF diet for 6 days. Body mass index (BMI) and fasting serum lipid profiles at baseline, after the wash-out diet, and after the HC/LF diet were measured. Results: APOA5-1131C carriers had higher triglyceride (TG) and TG-rich lipoprotein TG (TRL-TG) levels at baseline and after the HC/LF diet, though this mainly corresponded to the female cohort. APOC3-482T carriers had higher TRL-TG levels following the wash-out and HC/LF diets, but these were not directly attributable to a single gender. Conclusions: Both polymorphisms may play an important role in the elevated TG and TRL-TG levels induced by the HC/LF diet, especially in females, thus indicating a potential dietary prevention of coronary heart disease in this Chinese cohort.Digital Object Identifier http://dx.doi.org/10.1159/000327913
