A low saturated fat and low glycemic index diet appears to modulate the risk of developing dementia that eventually turns into Alzheimer's disease (AD). However, switching to this diet may not protect those already experiencing cognitive difficulty, according to this study.
The authors believe that instead of finding what health conditions affect Alzheimer's they should study the effects of whole-diet interventions on AD.
Jennifer L. Bayer-Carter, M.S., from Veterans Affairs Puget Sound Health Care System, Seattle, and colleagues sought to compare a high–saturated fat/high–simple carbohydrate diet (a macronutrient pattern associated with type 2 diabetes and insulin resistance) with a low–saturated fat/low–simple carbohydrate diet; the interventions were named HIGH and LOW, respectively. The authors evaluated the effects of these diets in 20 older adults who were healthy and 29 older adults who had amnestic mild cognitive impairment (aMCI), meaning they experienced some memory problems, a precursor to AD.

In a four-week randomized, controlled trial, 24 participants followed the HIGH diet and 25 followed the LOW diet. The researchers studied participants' performance on memory tests as well as their levels of biomarkers (biological substances indicative of AD), such as insulin, cholesterol, blood glucose levels, blood lipid levels and components of cerebrospinal fluid (CSF).
