Cutting calories lets yeast live longer

Earlier study that showed opposite result was flawed

MOTHER LODE   Yeast mother cells on a diet of 2 percent glucose bud an average of about 24 daughters in a lifetime. The more researchers reduce the glucose, and thus the calories, that yeast consume, the longer the fungi live and the more offspring they can produce.

Cutting calories keeps yeast alive and growing long past the time they’d usually stop reproducing, a large-scale study shows.
