Figure 4. Oxidative stress resistance of Drosophila raised on organic food.

Survivorship curves of female flies raised for 10 days on the indicated food sources. Flies were then transferred to media containing H₂O₂ and dead flies were counted twice daily (grey: conventional food; black: organic food; statistically significant changes (p<0.005) are indicated by asterisks). Median survival times of flies on conventional and organics food sources, respectively, are: potatoes: 24 and 30 hours (p<0.0001); raisins: 24 and 24 hours (p<0.0001); bananas: 30 and 30 hours (p<0.2172).
