Is it possible to achieve healthy aging through eating? Yeast research points the way to securing better health in our golden years. Scientists from the Babraham Institute suggest an alternative connection between diet and aging, based on studies in yeast. Dr. Jon Houseley and his team have publish
Researchers have found that dietary changes in yeast can lead to healthy aging without calorie restriction. By switching the yeast’s diet from glucose to galactose at an early age, the team was able to delay cellular aging and improve overall health, suggesting that dietary adjustments, rather than caloric restriction, could promote longevity and wellness in later life.
Scientists from the Babraham Institute suggest an alternative connection between diet and aging, based on studies in yeast. Dr. Jon Houseley and his team have published their experiments, demonstrating that healthy aging is achievable through dietary change without restriction by potentially optimizing diet and that ill health is not an inevitable part of the aging process.

The cells grown on galactose remained just as fit as young cells even late in life, despite not living any longer, showing that the period of ill health towards the end of life was dramatically reduced.
