Give us our daily protein

Protein is an essential component of our food, and protein intake thus must be actively regulated. Liu et al. identified a neural circuit that encodes protein-specific hunger in fruit flies. In protein-deprived animals, this circuit acted to simultaneously promote protein consumption and restrict sugar intake. Lack of protein induced changes in the protein-specific, but not sugar-specific, branch of this circuit.
