- Yeast provides scientists with a cellular structure to test anti-aging substances and see their reaction at a cellular level.
- Experts say short-term diets do not work as well as changing to healthy foods.
- They say dietary changes rather than caloric restriction increase lifespan and improve aging health.
Dietary changes without caloric restriction help maintain youth in yeast cells, according to researchers in the Epigenetics Programme at Babraham Institute in Cambridge, United Kingdom.
In a study published today in the journal PLOS Biology, the scientists reported that an unrestricted galactose diet in budding yeast minimized cell changes during aging, irrespective of diet later in life.
They say their findings could help promote healthy aging in humans.
Galactose is a simple sugar that is transformed into glucose in the liver
