It is not surprising to find data showing that a poor diet and lack of exercise correlated with an increased risk of later neurodegeneration and dementia. Plenty of studies exist to note that correlation. The question is the degree to which it is correlation versus causation. There are good reasons to believe that regular exercise slows the onset of neurodegeneration, quite clear mechanistic links that are demonstrated to be causal in animal studies. Equally, a poor diet and lack of exercise correlate with many other potential contributing factors in human populations, not least of which is frailty and other manifestations of aging. So to what degree do these correlations in human data r…
