Evaluation of Daily Tea Consumption on Lipid Profile Biomarkers in Healthy Volunteers.

is known in the field of herbal medicine and studies that it has beneficial effects such as antibacterial, antifungal, antidiabetes, and anti-inflammatory properties. We investigated whether tea consumption affects the plasma levels of lipid biomarkers in healthy volunteers. Thirty healthy Tunisian volunteers aged between 20 and 57 years old consumed infusion, prepared from 5 g of dried leaves in 100 ml boiled water, once a day during 10 days. Plasma concentrations of serum low-density lipoprotein (LDL) cholesterol, triglycerides and HDL (high-density lipoprotein) cholesterol were measured by Beckman Coulter D × 600 analyzer before consumption and at the end of the experiment. tea consumption significantly increased the concentration of HDL cholesterol ([HDL cholesterol] = 1.34 ± 0.25 pg/mL, =1.42 ± 0.29,  = 0.01). However, a slight decrease that was statistically non-significant in LDL cholesterol and triglycerides levels was observed ( < 0.05). These findings highlight the improving blood lipidic profiles, which means a possible positive effect on reducing the risk of cardiovascular disease of tea consumption in healthy volunteers. However, more powerful studies with an extended treatment period are required.
