There is accumulating evidence that interfering with the basic aging mechanisms can enhance healthy longevity. The interventional/therapeutic strategies targeting multiple aging hallmarks could be more effective than targeting one hallmark. While health-promoting qualities of marine oils have been extensively studied, the underlying molecular mechanisms are not fully understood. Lipid extracts from Antarctic krill are rich in long-chain omega-3 fatty acids choline, and astaxanthin. In this new study, researchers used C. elegans and human cells to investigate whether krill oil promotes healthy aging. "In a C. elegans model of Parkinson's disease, we show that krill oil protects dopaminergic neurons from aging-related...
