Lima Bean Compound Extends Lifespan In Lab Experiments

German researchers experimenting with fruit flies found that an isoflavone found in lima beans extended lifespan, increased fitness levels, and improved glucose balance – but only in males. Though a lot more research needs to be done in animals and humans to prove any connection between longer life and the isoflavone prunetin, the results suggest that the plant bioactive could someday help slow the aging process, in men at least.
