malabsorption of carbohydrate but not of triacylglycerol
An extract of black, green, and mulberry teas causes malabsorption
of carbohydrate but not of triacylglycerol in healthy volunteers1–3
Litao Zhong, Julie K Furne, and Michael D Levitt
ABSTRACT
Background: In vitro studies suggest that extracts of black, green,
and mulberry teas could interfere with carbohydrate and triacylglyc-
erol absorption via their ability to inhibit -amylase, -glucosidase,
sodium-glucose transporters, and pancreatic lipase.
Objective: We measured breath hydrogen and 13CO2 to investigate
the ability of an extract of black, green, and mulberry tea leaves to
induce malabsorption of carbohydrate and triacylglycerol in healthy
volunteers.
Design: In a crossover design, healthy adult volunteers randomly
ingested test meals with a placebo beverage or a preparation con-
taining an extract of black (0.1 g), green (0.1 g), and mulberry (1.0
g) teas. One test meal contained 50 g carbohydrate as white rice, 10 g
butter, and 0.2 g [13C]triolein, and the beverages contained 10 g
sucrose. The calorie content of the second test meal consisted en-
tirely of lipid (30 g olive oil and 0.2 g [13C]triolein). Breath-
hydrogen and 13CO2 concentrations were assessed hourly for 8 h,
and symptoms were rated on a linear scale.
Results: With the carbohydrate-containing meal, the tea extract
resulted in a highly significant increase in breath-hydrogen concen-
trations, which indicated appreciable carbohydrate malabsorption.
A comparison of hydrogen excretion after the carbohydrate-
containing meal with that after the nonabsorbable disaccharide lac-
tulose suggested that the tea extract induced malabsorption of 25%
of the carbohydrate. The tea extract did not cause triacylglycerol
malabsorption or any significant increase in symptoms.
Conclusion: This study provides the basis for additional experi-
ments to determine whether the tea extract has clinical utility for the
treatment of obesity or diabetes. Am J Clin Nutr 2006;84:
551–5.
