Study on the Effects of Wheat and Corn Germ Blend Oil on Antioxidation and Immune Regulation of Dyslipidemia Population

Oxidative Stress Clinical Trial

Official title: Effects of Phytosterol-rich Wheat Corn Germ Blended Oil on Immune Function, Oxidative Stress, Serum Metabolites and Intestinal Flora in Dyslipidaemic Population: A Randomised Controlled Trial

Status Active, not recruiting

Clinical Trial Summary

The goal of this clinical trial is to explore the role of wheat and corn germ blended oils in regulating oxidative stress and immunomodulation in dyslipidaemic populations, to explore their effects on intestinal flora, antioxidant and immunomodulation. The main questions it aims to answer are:

• How does phytosterol-rich wheat corn germ blended oil affect oxidative stress and immune function in dyslipidaemic people compared to peanut oil?

• How does phytosterol-rich wheat corn germ blended oil affect serum metabolites, serum fatty acid profile, and intestinal flora in dyslipidaemic populations compared to peanut oil? What are the specific mechanisms involved?

Participants will be randomly assigned to the intervention and control groups, the packaging of germ oil and peanut oil will have a uniform appearance, and participants will be instructed to replace their household cooking oils with the distributed cooking oil for three months, in addition to replacing all the canteens in the staff units with the trial oil for more than three months. Participants did not know who was the control oil, germ oil or peanut oil, and both were randomly distributed to different groups of participants by the third-party supervisors.

Researchers will compare peanut oil to see if phytosterol-rich germ oil can improve oxidative stress and immune function in dyslipidaemic populations, in addition to exploring possible underlying mechanisms of improvement using multi-omics techniques.

Clinical Trial Description

The design of this intervention trial was a randomised controlled trial, in which the included dyslipidaemic population was randomly divided into a wheat corn germ blended oil intervention group and a peanut oil control group, with the male/female ratio, age, and level of basic clinical characteristics balanced between the two groups. The entire test phase consisted of a 14-day washout period and a 3-month intervention period. Participants in the intervention and control groups first entered a 14-day peanut oil washout period, which was followed by a three-month intervention phase. During the intervention phase, two different cooking oils (25-30 g of cooking oil per day according to the recommended intake of the Chinese Nutrition Society) were allocated to the two groups, with peanut oil being consumed by participants in the control group, and germ oil being used to replace the daily cooking oil for participants in the intervention group. After the participants were randomised into groups, they were provided with lunch and dinner according to the Chinese Dietary Guidelines for Residents of China and the local dietary habits of Nanjing, China, and breakfast was provided by the subjects themselves (dietary guidance was given to the subjects during the course of the study, and breakfast recipes were provided uniformly in order to achieve consistency between the two groups), and the intervention period was 3 months. Throughout the project period, all subjects followed their normal dietary habits and maintained a normal level of physical activity. ;
