Fructose Malabsorption in African Americans

by mbaker on April 11, 2013

Researchers at the University of Southern California have noted that both Hispanics and African Americans have a diet high in fructose containing beverages.  African Americans have a much higher incidence of fructose malabsorption than Hispanics as assessed using the hydrogen breath test.  Interestingly, African Americans have a much lower rate of fatty liver disease suggesting that fructose malabsorption in African Americans may serve as a protection against fatty liver disease.  The evidence produced by the researchers based on 16 African Americans who when tested using the hydrogen breath test were 75% positive for fructose malabsorption. Those with fructose malabsorption had significantly less volumes of fat tissue on the liver versus those testing negative.
