![]() ![]() “The genes that regulate many processes are conserved,” Kapahi says. The same thing happens, through much the same mechanism, in flies that are deprived of protein.īut when flies are deprived of sugar, they gravitate toward sugary food, says study author Pankaj Kapahi, a geneticist at the Buck Institute for Age Research.įruit flies are an ideal organism for studying biology: their genetics have been heavily explored, and genes are widely shared among organisms. After a female mates, for example, the switch guides her toward the protein-rich fungus on a rotten peach. ![]() In fact, there are signs that this decision could result from the same mechanism that operates in fruit flies - but we’re flying ahead of ourselves.Ī study of fruit flies published today in Current Biology explores a “dietary switch,” a chemical mechanism that forces the fly to eat what it needs. NBC’s storyboards may suggest that you eat lean, and you may want to become the biggest loser, but your food choices could be less the result of a conscious decision than a response to some tongue-twisting chemicals floating through your cerebral backwaters.
