Summary: In a double-blind, placebo-controlled, crossover study involving 12 healthy adults (3 men, 9 women; mean age: 22 years) on a high-lipid diet, results indicate that drinking polyphenol-enriched oolong tea may increase fecal lipid excretion. The subjects received about 38 g of lipids from potato chips (19 g each within 30 minutes after lunch and dinner) and 750 ml of a placebo beverage or polyphenol-enriched oolong tea daily for 10 days. After a 7-day washout period, the interventions were crossed over for another 10 days. Fecal excretion of lipids was measured on the last 3 days of each intervention period from collected stool samples. Lipid excretion into feces was found to be significantly higher during the polyphenol-enriched oolong tea intervention period, compared to the placebo period. Additionally, an increase in cholesterol excretion was found in the polyphenol-enriched oolong tea intervention period, compared to the placebo period. Thus, the authors conclude, "The results of this study indicated that polyphenol-enriched oolong tea could increase lipid excretion into feces when subjects took high-lipid diet."
