SREBF1 Polymorphism and Egg Yolk on Cardiovascular Disease Risk in Healthy Young Adults: a Randomised, Two-period, Single Blinded, Crossover Trial
- Conditions
- HealthyGEN1 Gene Mutation
- Interventions
- Dietary Supplement: Egg yolksDietary Supplement: Macronutrients equivalent control
- Registration Number
- NCT04975048
- Lead Sponsor
- Shandong University
- Brief Summary
Our previous analysis showed that sterol regulatory element binding protein gene (SREBF1) rs2236513/rs2297508/rs4925119 polymorphism modulated the relation between dietary cholesterol and serum low density lipoprotein cholesterol /serum total cholesterol. This study aims to confirm and extend this finding by characterizing the effects of cholesterol from egg yolks on lipid profiles in healthy young adults with different SREBF1 genetic makeup. 32 SREBF1 C/G/G minor allele carriers at rs2236513/rs2297508/rs4925119 and 32 SREBF1 AA/CC/AA major homozygotes at rs2236513/rs2297508/rs4925119 were enrolled to test their response to egg yolks.

Group Intervention Description Group A Macronutrients equivalent control Group A was consisted of 16 rs2236513/rs2297508/rs4925119 C/G/G carriers and 16 AA/CC/AA homozygotes. And it was first assigned egg yolk intervention during intervention period 1, and then macronutrient equivalent control during intervention period 2 Group B Egg yolks Group B was also consisted of 16 rs2236513/rs2297508/rs4925119 C/G/G carriers and 16 AA/CC/AA homozygotes. It was first assigned macronutrient equivalent control during intervention period 1, and then egg yolk during intervention period 2 Group A Egg yolks Group A was consisted of 16 rs2236513/rs2297508/rs4925119 C/G/G carriers and 16 AA/CC/AA homozygotes. And it was first assigned egg yolk intervention during intervention period 1, and then macronutrient equivalent control during intervention period 2 Group B Macronutrients equivalent control Group B was also consisted of 16 rs2236513/rs2297508/rs4925119 C/G/G carriers and 16 AA/CC/AA homozygotes. It was first assigned macronutrient equivalent control during intervention period 1, and then egg yolk during intervention period 2
