One finding from experiments with older mice is particularly exciting. A short-term change in diet resulted in certain protein markers approaching the patterns of younger animals. This shows that nutrition can still have a measurable effect on central molecular processes even at an advanced age. The results thus provide new starting points for research into neurodegenerative diseases and suggest that the protein balance of the brain not only changes with age, but can also be specifically influenced. This opens a window for future strategies to slow down age-related damage to nerve cells and maintain brain performance for longer.
