Brain Healthy Diet for Dementia and Alzheimer’s: 7 Top Food Choices
As Alzheimer’s disease touches more families each year, many people find themselves searching for ways to offer support to a loved one facing cognitive challenges. While there is no cure for memory loss, research continues to highlight how small, thoughtful choices, especially around nutrition, may help promote brain health, reduce dementia risk, and potentially slow progression.
At Lakewood Memory Care and Assisted Living in Brookfield, Wisconsin, we know that wellness begins with daily habits and that’s why we take a mindful approach to every meal we serve. Our caring community embraces a balanced diet as one way we can support residents on their individual journeys with mild cognitive impairment or Alzheimer’s.
This blog explores how a brain healthy diet, particularly one inspired by the Mediterranean style of eating, may help offset genetic risk, support cognitive function, and provide comfort along the way.
Understanding the Link Between Nutrition and Brain Health
Nutrition plays an essential role in the way the brain functions, especially in older adults navigating the path of developing dementia. Research shows that certain dietary factors influence blood metabolites linked to key metabolic pathways, the very systems that impact memory, processing, and emotional regulation.
Even for those with a strong genetic risk, studies suggest that a nutrient-rich diet for dementia and Alzheimer’s may help protect against the effects of cognitive and functional decline. At Lakewood, our culinary team prepares meals with these insights in mind, offering options that are both comforting and aligned with the latest research on brain aging.
While food alone cannot reverse disease progression, the way the body processes nourishment, especially in a supportive and engaging environment, can make a meaningful difference in how a resident feels each day. Embracing a healthy lifestyle that includes good nutrition is one way we help residents feel empowered and supported in their day-to-day life.
The Mediterranean Diet and Its Connection to Dementia Risk
Among the many dietary approaches studied, the Mediterranean diet stands out as one of the most promising for reducing dementia risk. It is one of the only dietary patterns consistently linked to slower cognitive decline and is particularly valuable for individuals with a higher genetic risk of developing Alzheimer’s disease.
This way of eating emphasizes wholesome, natural ingredients like fruits, vegetables, whole grains, legumes, lean proteins, olive oil, and nuts. It also includes low fat dairy products in moderation, which can provide important nutrients that support brain and bone health. These foods, rich in antioxidants, fiber, and polyunsaturated fatty acids, are known to protect brain cells and support cardiovascular health — which in turn affects the brain’s ability to function well.
At Lakewood, our culinary team focuses on preparing brain healthy meals inspired by current research in cognitive wellness. Each dish is thoughtfully prepared to support overall well-being, with flexibility to meet resident’s needs and nutritional goals.
7 Top Foods That Support Cognitive Function
Incorporating certain foods into a resident’s diet can offer support for memory, clarity, and overall wellness. Our kitchen team includes these nutrient-rich ingredients in our rotating menus, with love and intention behind every dish.
1. Leafy Greens
Spinach, kale, and other greens are packed with nutrients like vitamin K, folate, and lutein. These compounds have been linked to slower cognitive decline in both observational and randomized trial settings.
2. Berries
Blueberries and strawberries contain flavonoids that may reduce oxidative stress in the brain. The Nurses Health Study found that frequent berry intake was associated with improved memory and delayed brain aging.
3. Olive Oil
A staple of the Mediterranean diet, olive oil is rich in heart-healthy fats that support blood flow to the brain. Its anti-inflammatory properties may also help reduce risk of developing dementia in later life.
4. Whole Grains
Whole grains such as brown rice, quinoa, and oats offer steady energy and help maintain heart health — both important for cognitive health and managing age related cognitive decline.
5. Fatty Fish
Fish like salmon and sardines are excellent sources of omega-3 fatty acids, which are essential for brain health. These fats are among the most well-researched dietary factors in relation to reducing dementia risk.
6. Nuts
Walnuts, almonds, and other nuts are rich in vitamin E, an antioxidant that supports brain aging and may help lower the risk of developing dementia, especially in high risk groups.
7. Legumes
Beans, lentils, and chickpeas are full of fiber, protein, and nutrients that stabilize blood sugar levels and promote heart and brain health, helping support those facing cognitive impairment.
Offset Genetic Risk with Nourishing, Person-Centered Support
While some individuals face a higher genetic risk of developing Alzheimer’s disease due to inherited traits like the APOE-e4 gene, dietary strategies can still make a difference. Studies that examined participants’ blood samples and genetic data show that those who adhered to brain healthy diets, like the Mediterranean diet, experienced cognitive benefits regardless of their participant's inherited risk.
At Lakewood, we recognize that nutritional needs vary, especially when genetic and metabolic factors come into play. Meals are thoughtfully prepared, beautifully plated, and served in a warm setting that encourages connection and conversation, whether during daily meals or special family events held in our gathering spaces.
Health professionals, including caregivers and culinary staff, work together to provide personalized nutritional advice that reflects each resident’s preferences and clinical needs. Our goal is to create a diet rich in variety, flavor, and intention — one that supports not only brain function but overall happiness and comfort.
Life at Lakewood means Nourishing More than Just the Body
Our commitment to wellness goes beyond what’s on the plate. At Lakewood, we create an environment where nutrition, routine, and enrichment all work together to support cognitive health and emotional well-being. Residents enjoy a full calendar of physical and mental activities, from gardening to devotional readings to strength training and musical games, with each one carefully designed to engage the senses and strengthen memory.

Frequently Asked Questions
What is the genetic risk for developing Alzheimer’s disease?
The most well-known genetic risk factor is the APOE-e4 gene. However, having this gene does not mean a person will definitely develop Alzheimer’s, and many lifestyle choices, including a healthy and balanced dementia diet, may help offset genetic risk and support a lower risk of cognitive decline over time.
How do dietary factors influence cognitive health?
Dietary factors such as antioxidants, healthy fats, and fiber can help reduce inflammation, improve circulation, and support brain cell health, all of which can positively impact cognitive function over time. A dementia diet that includes brain-healthy foods like leafy greens, berries, and olive oil can play a valuable role in reducing dementia risk.
What makes the Mediterranean style diet different from the MIND diet?
The Mediterranean diet is more flexible and includes a broader range of brain healthy foods. While the MIND diet was originally designed for Alzheimer’s prevention, many communities now emphasize the Mediterranean diet due to its variety, numerous benefits, and its proven connection to a lower risk of developing dementia.
Can cognitive impairment be improved with food alone?
While food alone cannot reverse cognitive impairment, it plays a supportive role in overall health. When combined with social engagement, physical activity, and emotional support — all of which are part of daily life at Lakewood — nutrition becomes a powerful tool. Our dementia diet approach reflects this balance between nourishment, connection, and wellness.
What does future research suggest about nutrition and Alzheimer’s?
Ongoing studies continue to explore the genetic and metabolic basis of dementia, using tools like food frequency questionnaires and clinical risk prediction models to better understand how diet and genetics interact. Researchers continue to call for more research to strengthen the link between diet and brain health, helping health professionals refine nutritional strategies that can reduce dementia risk and support long-term wellness.
