EGCG was a gift from Mitsui Norin. Commercial low-fat diet (LF; 10%
energy as fat), high-fat diet (HF; 60% energy as fat), and high-fat plus
EGCG (HFE; 60% energy as fat, 3.2 g EGCG/kg diet) diet (Table 1) were
prepared by Research Diets. Briefly, each ingredient was weighed (within
0.5% of amount needed) and blended to homogeneity in the appropriate
powdered diet. The mixture was then formed into equally sized pellets
and placed into a temperature- and humidity-controlled room to remove
the moisture from the diet.
