Link Between Diet and Memory Loss

A provocative new research study suggests memory loss may be linked to a diet high in saturated fat and cholesterol.

Loss of memory with advanced age is a significant problem within most societies, and appears particularly severe in advanced industrialized nations.

Researchers from the Medical University of South Carolina (MUSC) believe they have found a connection between memory loss and a diet high in saturated fat and cholesterol.

The study is published in the June issue of the Journal of Alzheimer’s Disease.

Collaboration between two laboratories at MUSC and one at Arizona State University led researchers to discover that rodents that were fed a diet high in cholesterol and saturated fat displayed impairment in working memory.

This memory loss is associated with inflammation in the brain, as well as the impairment of structural proteins that affect how a nerve cell functions. As inflammation is associated with a poor diet, the failure of functions in other key organs such as the eye and the ear also could be expected.

Assuming that the same phenomenon occurs in human beings, the study suggests that as humans age, memory may be preserved and brain functions improved by restricting the consumption of cholesterol and saturated fats.

As cases of obesity and obesity-related diseases have increased exponentially in the United States, and are second only to tobacco use for premature mortality and the number of health-care dollars spent, the importance of this issue is immediate.
