Dementia, a condition that affects millions, has spurred a quest for preventive measures, especially those related to diet. The MIND diet, or Mediterranean-DASH Intervention for Neurodegenerative Delay, has emerged as a promising approach. This article delves into the MIND diet and explores some of the best books available to guide you on this journey toward better brain health.
The Genesis of the MIND Diet
The MIND diet was developed by Dr. Martha Clare Morris and her colleagues at Rush University Medical Center and the Harvard T.H. Chan School of Public Health. Dr. Morris, a professor of epidemiology and director of the Rush Institute for Healthy Aging, led the research team that published two pivotal papers in 2015, introducing the MIND diet to the world.
The research was based on the Rush Memory and Aging Project (MAP), a study that followed over 1,000 older adults for up to 10 years. These participants, who were dementia-free at enrollment, completed annual dietary questionnaires and underwent cognitive assessments. The MIND diet score was developed to identify foods and nutrients, along with daily serving sizes, related to protection against dementia and cognitive decline.
The study identified fifteen dietary components, classifying them as either “brain healthy” or unhealthy. Participants with the highest MIND diet scores experienced a significantly slower rate of cognitive decline compared to those with the lowest scores. The goal was to determine if the MIND diet, drawing from the Mediterranean and DASH diets, could directly prevent or slow the progression of dementia.
Core Principles of the MIND Diet
The MIND diet emphasizes plant-based foods while limiting animal products and foods high in saturated fats. It recommends specific "brain healthy" foods to include regularly and identifies five unhealthy food items to limit. While the diet specifies daily and weekly amounts of foods to include and avoid, it doesn't restrict the diet to only these foods, offering flexibility in meal planning.

Key Components:
Brain-Healthy Foods to Emphasize:
- Green leafy vegetables: Aim for at least six servings per week.
- Other vegetables: Include at least one serving a day.
- Nuts: Have at least five servings per week.
- Berries: Eat at least two or more servings per week.
- Beans: Consume at least three meals a week.
- Whole grains: Aim for at least three servings a day.
- Fish: Have one serving a week.
- Poultry: Eat two servings a week.
- Olive oil: Use it as your main cooking oil.
- Wine: While originally included in the MIND diet score, it has been omitted in subsequent trials for safety reasons. Whether to include alcohol is a personal decision that should be discussed with your healthcare provider.
Foods to Limit:
- Red meat: Limit to less than four servings a week.
- Butter and margarine: Use less than 1 tablespoon (14 grams) daily.
- Cheese: Limit to less than one serving a week.
- Pastries and sweets: Limit intake.
- Fried or fast food: Limit intake.
The MIND Diet: A Flexible Approach
The MIND diet stands out for its flexibility. Unlike rigid meal plans, it allows individuals to create their own meals and recipes based on recommended foods. This adaptability makes it a sustainable choice for many, though it may pose a challenge for those unfamiliar with cooking. The MIND diet can be a healthful eating plan that incorporates dietary patterns from the Mediterranean and DASH, both of which have suggested benefits in preventing and improving cardiovascular disease and diabetes, and supporting healthy aging. When used in conjunction with a balanced plate guide, the diet may also promote healthy weight loss if desired.
Benefits of the MIND Diet
The MIND diet offers numerous potential benefits, primarily related to cognitive health.
- Reduced Risk of Dementia and Alzheimer's Disease: Research has found a 53% lower rate of Alzheimer’s disease for those with the highest MIND diet scores. Even moderate adherence to the diet showed a 35% lower rate compared to those with the lowest scores.
- Improved Brain Health: The diet contains foods rich in vitamins, carotenoids, and flavonoids, believed to protect the brain by reducing oxidative stress and inflammation.
- Improved Heart Health: As a combination of the Mediterranean and DASH diets, the MIND diet promotes heart health.
- Healthy Aging and Longevity: Following the MIND diet has been shown to reduce the risk of all-cause mortality by 37% over 12 years.
Potential Downsides
While the MIND diet is generally considered safe, some factors may pose challenges for certain individuals.
- Socioeconomic Factors: Research has found that greater poverty and less education are strongly associated with lower MIND diet scores and lower cognitive function.
- Cooking Skills: The flexibility of the MIND diet requires individuals to create their own meal plans, which may be challenging for those who do not cook.
MIND Diet Books
Several books offer guidance and recipes for following the MIND diet. Here are a few notable examples:
