Abstract

Drosophila melanogaster were fed matcha green tea combined with either honey or Splenda over ten days, and assessed for survival, weight, locomotor performance and memory. Survival and memory were unaffected, but the high-sugar honey diet with matcha produced significantly poorer climbing performance, suggesting matcha does not offset the costs of a high-sugar diet.
