ABSTRACT
OBJECTIVE: To explore the effects of different aging years of Liupao tea on metabolic indexes and body composition.
METHODS: Subjects who met the inclusion criteria were recruited in March 2024 in some communities in Haidian District, Beijing, and randomly assigned to the one-year and seven-year Liupao tea aging groups to receive the tea drinking intervention, with a dose of 6 g/d per person, which was brewed with 250 mL of boiled water for 30-45 seconds in the morning of each day and then consumed. Before and three months after tea drinking, fasting blood glucose, glycated haemoglobin, serum total cholesterol, triglyceride, triglyceride, high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol(LDL-C) level was measured, and the subjects' body composition indexes such as protein, body fat mass, and muscle mass were measured by using IOI353 Body Composition Analyser. Using the international common scale, the subjects' sleep and appetite were measured before and after the intervention. Compared the effects of Liupao tea of different aging years on the metabolic indexes, body composition and sleep of the subjects.
RESULTS: After three months of intervention, the metabolic indexes of the subjects' LDL-C cholesterol level decreased by 0.21 mmol/L(P<0.05), the HDL-C cholesterol level increased by 0.05 mmol/L(P<0.05), the total cholesterol level of those with abnormal levels decreased by 0.34 mmol/L(P<0.05). The level of those with abnormal blood pressure decreased from 138.6/82.3 mmHg to 123.4/77.4 mmHg(P<0.05). In the body composition index, BMI decreased from(25.4±2.9) to(24.8±2.7)(P<0.05), muscle mass increased from 40.3(37.1, 46.4) kg to 40.7(37.2, 47.0)kg(P<0.05), body fat decreased from(21.5±4.9)kg to(19.7±4.6)kg(P<0.05), and other parts of the body composition indexes such as protein also improved. The body fat decreased from(21.5±4.9)kg to(19.7±4.6)kg(P<0.05), and other body composition indicators such as protein also improved; the anxiety symptoms of the subjects also improved after 3 months of drinking tea(P<0.05). However, there was no statistically significant difference in the effects of different aging years of Liupao tea on the metabolic indexes and body composition of the subjects.
CONCLUSION: The health effects of drinking Liupao tea water such as lipid-lowering and muscle building were significant, but there was no significant difference in the effects of different aging years of Liupao tea on the population.
