A recent analysis of participants in the FINGER study tracked about 600 people (average age around 69) for 2 years. Those with better muscle strength and function at the start of the study as measured through tests like grip strength and chair stand had better global cognition, memory, and executive function at the end after correcting for variables like age and comorbidities. However, in some recent publications, there’s a signal that building leg muscle may be especially key to brain health.

Every week, there’s a new conversation about a superfood, supplement or toxic ingredient for brain health. And as of right now, the significance of almost every one of these topics pales in contrast with the effect of overall dietary patterns. Now a landmark study from the UK Biobank further solidifies this point, tracking over 121,000 people across an average of nearly eleven years. These findings carry real implications for every one of us who cares about keeping our minds sharp as we age.

merging research suggests that one of the most powerful nutrients for overall and brain health could be a carb, and almost nobody is eating the recommended amount. In this article, we’re breaking down the science on dietary fiber, and why it may still be one of the best-kept secrets for longevity, overall wellness and especially brain health and cover considerations around low-carb diets.
