Healthy Diet: Nutritious Food Intake In Early Life Matters In Ageing Gracefully, Says Study
[ad_1]
Yeast are good model organisms for studying ageing as they share many of the same cellular machinery as animals and humans.
According to researchers at the Babraham Institute in UK, healthy ageing is achievable through dietary change without restriction by potentially optimising diet, and that ill-health is not an inevitable part of the ageing process. Scientists have long known that caloric restriction -- intentionally consuming far less calories than normal without becoming malnourished -- improves health in later life and may even extend life. However, studies in mice show that caloric restriction really needs to be maintained throughout life to achieve this impact, and the health benefits disappear when a normal diet is resumed.
The new research, published in the journal PLOS Biology, conducted in yeast suggests an alternative to calorie restriction can lead to improved health through the lifecycle.
“We show that diet in early life ...
