Better Diet Can Help Prevent the Development of Dementia as People Age

"Insights & Implications in Gerontology: The Vital Role of Nutrition in Brain Health,"a new publication from the Gerontological Society of America, explores nutritional choices that have been shown to improve cognition and decrease the risk of cognitive impairment and dementia in older adults.

Consumption of a healthful diet is a behavioral strategy that can help to prevent the development of dementia as people age, the publication says. It also reports on the roles of vitamins and minerals in nutrition and brain function and focuses on how to implement person-centered conversations about the impact of diet and nutrition on overall wellness, including brain health.

Using a person-centered approach that ties conversations about nutrition to patient goals is an effective strategy for starting conversations about diet and health, according to Kathryn Porter Starr, PhD, RDN from Duke University School of Medicine and Durham VA Medical Center, who served as one of the faculty who oversaw the publication's development.

Broaching the topic of diet and nutrition can be challenging. I start by asking patients what their goals are. These goals could include physical goals such as maintaining muscle mass, cognitive goals such as preserving memory, as well as functional goals such as being able to travel or play with grandchildren. Linking information about nutrition to helping adults achieve their goals is an effective strategy for stimulating motivation to implement healthy changes."

The Mediterranean-DASH Diet Intervention for Neurodegenerative Delay, or MIND diet, is an example of a dietary pattern that is associated with improved cognition. This dietary pattern focuses on the consumption of vegetables (especially green leafy vegetables), nuts, berries, beans, whole grains, fish, poultry, and extra virgin olive oil while limiting red meat, processed meats, butter and margarine, regular cheese, pastries and sweets, and fried foods. People who consume this dietary pattern have been found to be the equivalent of 7.5 years younger in terms of cognitive abilities. The publication includes more details about the MIND diet and other dietary patterns that support healthy nutrition.

Ideally, individuals are able to obtain all necessary nutrients from their diet. However, the risk for inadequate vitamin and mineral intake increases as people age, and some people may benefit from consumption of fortified foods and or dietary supplements to enhance their nutritional status.

"I would love for everybody to get all of their micronutrients from food," Starr said. Unfortunately, for most older adults, it's really challenging to do that due to physiological changes that occur with aging and certain disease states that affect absorption, so we often recommend a multivitamin."

The Gerontological Society of America (GSA) is the nation's oldest and largest interdisciplinary organization devoted to research, education, and practice in the field of aging. The principal mission of the Society -; and its 5,500+ members -; is to advance the study of aging and disseminate information among scientists, decision makers, and the general public. GSA's structure includes a nonpartisan public policy institute, the National Academy on an Aging Society, and GSA is also home to the National Center to Reframe Aging and the National Coordinating Center for the Resource Centers for Minority Aging Research.
