Calories, Obesity, and Memory Loss

Contributed by: Dennis Fortier, President, Medical Care Corporation

The stated purpose of this blog is to clarify the daily news about brain health.  Certainly, a lot of the reporting in this space needs to be filtered and contextualized for clarity.  But not all of it.

I noticed a very well-written article published today in the Pacific Standard,  describing research about the relationships between high calorie diets and memory loss, as well as between obesity and overall cognition.  I will summarize the main points below but I encourage you to click through and read this excellent piece of reporting.

According to a Mayo Clinic study published in the Journal of Alzheimer's Disease, high calorie diets (exceeding a threshold of 2143 calories/day) are associated with higher risk for cognitive impairment among the elderly.  The article also summarizes other research concluding that obesity in mid-life is a risk factor for dementia, and that weight loss can improve memory and organizational skills.

Overall, this is a well-organized summary of evidence that managing cardiovascular health through proper diet may have a clear and significant impact on overall cognitive health.
