Green Tea Inhibits Fat Gain, But Will It Also Hinder Muscle Gain? Decreased Protein Absorption in Rats Supplemented With Green Tea Extract
It has gotten relatively quiet around green tea within the past weeks. Everybody knows about its anti-oxidant effects, its modest efficacy as a weight loss supplement and the relaxing effect of taking a time-out from the stressors of daily life with a good cup of freshly brewed tea. Now, scientists from Poland ( Bajerska. 2011 ) found another interesting, yet not so beneficial property of green tea extract. The scientists fed laboratory rats on a high fat diet chow with either 0%, 1.1% or 2.2% of green tea extract [GTAE] added and found that only the chow containing 2.0% GTAE had significant effects on body weight gain (5.6% less than control) and visceral fat accumulation (-17.8% vs. control). Yet, they observed a [...] considerably ( P < .05), reduction in the digestion of protein (but not fat) was observed in both GTAE groups (1.1% GTAE: 82.6% ± 1.8%; 2.0% GTAE: 84.3% ± 0.8%) when compared to the control (93.3% ± 1.5%). This novel finding appears to stand in line with pr...
