Diets high in hydrogenated vegetable fat induce depression-like and anxiety-like phenotypes in Drosophila adults; increased aggressive activities are also observed. A diet high in saturated fat induces depression-like phenotypes, but not behaviors associated with anxiety or increased aggressive behaviors. With both types of diets, significant drops in serotonin and octopamine are observed.
Male-male aggression has been assessed in adults that developed on a low-, medium- or high-resource diet, manipulated via yeast content. Animals raised on the resource-poor diet exhibited reduced levels of male-male aggressive behaviors.
