Fruit flies remember their larval diet, which influences their longevity
Meal memory Fruit flies remember their larval diet, which influences their longevityvar abtest_2174132 = new ABTest(2174132, 'click'); Eating less protein as larvae may limit their ability to produce proteins as adults. The same effect has since turned up in fruit flies and mice. What we did not know was how a meal eaten in infancy could affect health weeks, months, or even years later.
