Abstract
Background: Green tea, which is an easily available product, contains catechin, a substance demonstrating anti-oxidant, and anti-inflammatory properties in addition to reducing serum lipid levels. However, the relationship between green tea intake and serum lipid levels remains unclear. We investigated the relationship between green tea intake and serum lipid levels in healthy adults.

Methods: Among the 23,626 patients who were enrolled in the National Health and Nutrition Examination Survey performed in 2012, 2013, and 2014, a total of 7,456 patients responded to questions related to green tea intake, excluding those with factors that affect serum lipid levels. Based on their daily green tea intake, we classified patients into 4 groups: those drinking 0, 1, 1?2, and ¡Ã2 cups per day. Analysis of covariance was used to determine the relationship between green tea consumption and serum lipid levels.

Results: Among the 2,847 men included in the study, the percentage of men consuming ¡Ã1 cups per day was 7.7%, and among 4,559 women, 5.3%. Age, body mass index, and smoking habits showed a statistically significant difference between the sexes; however, serum lipid levels were not statistically significantly different. No statistically significant difference was observed in the relationship between green tea intake and serum lipid levels after adjustment for confounders.

Conclusion: In this study, the amount of green tea consumed on a daily basis did not seem to have a significant effect on serum lipid levels.
