Mediterranean-DASH Diet (MIND)

This study examines how physical activity and adherence to the MIND diet influence cognitive impairment among 462 adults aged 65+ in Pakistan. Using validated assessment tools, researchers found that 26.4% of participants had mild cognitive impairment, and 48.5% had low adherence to the MIND diet. Low physical activity increased cognitive impairment risk (AOR: 9.94, CI: 6.07–16.27), while higher MIND diet adherence lowered risk (OR: 0.29, CI: 0.18–0.46). The cross-sectional nature of the study means causality cannot be established, but it highlights the need for lifestyle interventions to protect cognitive health. Findings suggest regional and socioeconomic disparities affect cognitive aging, urging targeted public health efforts.

This review explores how dietary habits influence cognitive function through the gut-brain axis. It highlights the Mediterranean, plant-based, and low-carbohydrate diets, which are rich in antioxidants and neuroprotective nutrients, potentially reducing cognitive decline and neurodegenerative disease risks. These diets support brain health by lowering inflammation, oxidative stress, and improving neurogenesis. While dietary interventions show promise, challenges such as adherence and individual variability must be addressed. Future research should focus on large-scale, long-term randomized trials to refine dietary recommendations for cognitive health.

This meta-analysis investigates the protective effects of the Mediterranean diet on cognitive impairment, dementia, and Alzheimer’s disease. The diet, rich in fruits, vegetables, whole grains, fish, and olive oil, was associated with an 11–30% reduced risk of cognitive decline. Key components such as omega-3 fatty acids, polyphenols, and antioxidants promote brain and vascular health, reduce inflammation, and support neuroprotection. These findings emphasize the Mediterranean diet as a viable non-pharmacological approach to mitigating cognitive decline, dementia, and Alzheimer's disease, making it a cornerstone of public health strategies for healthy aging.

This critical review evaluates neuroprotective diets such as the Mediterranean, DASH, and MIND diets in reducing cognitive decline. These diets are rich in antioxidants, healthy fats, and nutrients that support brain health, potentially reducing risks of Alzheimer’s and dementia. However, findings across 5 randomized clinical trials (RCTs) and 27 observational studies were inconsistent due to varied dietary scoring methods, cognitive assessment tools, and study durations. Despite gaps, these diets show promise in slowing cognitive decline and warrant further high-quality, long-term trials.

This study examined how adherence to a MIND diet—a combination of the Mediterranean and DASH diets—affects brain health in older women exposed to air pollution (PM2.5). The researchers found that women who followed the MIND diet had larger white matter brain volumes, a marker of healthy aging. For those not following the diet, air pollution was linked to greater brain volume loss. The findings highlight the potential of the MIND diet to protect against brain aging and mitigate some of the harmful effects of environmental factors like air pollution.

This randomized controlled trial investigated the effects of combining aerobic exercise with the MIND diet (a blend of Mediterranean and DASH diets) on brain health in postmenopausal women with mild cognitive impairment (MCI). Over 12 weeks, participants following both interventions improved cognitive function and physical independence more than those on the diet alone. These results suggest that regular exercise enhances the neuroprotective effects of the MIND diet, promoting brain health despite hormonal changes related to menopause.

This study examined the MIND diet's impact on dementia and Alzheimer's disease (AD) risk in a French older population. Over nearly 10 years, participants with higher adherence to the MIND diet—rich in leafy greens, nuts, berries, and fish—had a significantly lower risk of developing dementia and AD. MRI scans showed that a higher MIND diet score was linked to greater gray matter volume and cortical thickness in brain regions affected by AD. These findings suggest that the MIND diet may protect brain structure and delay cognitive decline.

This cohort study investigated the long-term effects of adherence to the MIND diet on cognitive function and decline in over 16,000 older women. The MIND diet emphasizes leafy greens, berries, nuts, and whole grains, while limiting unhealthy foods. Results showed that greater adherence was moderately associated with better verbal memory but did not significantly impact global cognition or the rate of cognitive decline over six years. The findings highlight the potential of the MIND diet to support certain aspects of cognitive health, particularly in aging populations.

This study analyzed how adherence to the MIND diet—combining elements of the Mediterranean and DASH diets—affects dementia risk. Using data from three cohort studies and a meta-analysis, the research found that individuals who followed the MIND diet closely had a lower risk of developing dementia. The diet emphasizes foods like leafy greens, berries, nuts, and whole grains while limiting red meat, butter, and sweets. These findings suggest that dietary patterns rich in antioxidants and anti-inflammatory nutrients may support brain health and cognitive longevity.

This systematic review examined the MIND diet's effects on cardiometabolic health. Combining elements from Mediterranean and DASH diets, the MIND diet emphasizes plant-based foods like berries, leafy greens, and whole grains while limiting unhealthy foods. Studies reviewed included observational and randomized controlled trials (RCTs) and showed significant improvements in markers such as waist circumference, BMI, blood sugar, and cholesterol. Some studies indicated reduced risks for diabetes, stroke, and inflammation. While results are promising, variations in study quality and design mean further research is needed. The MIND diet's cardiometabolic benefits complement its established role in cognitive health.

The paper reviews how diet influences mental health through molecular mechanisms. It highlights how components like omega-3 fatty acids, polyphenols, and B vitamins support brain function by reducing inflammation and oxidative stress, enhancing neurogenesis, and improving neurotransmitter activity. Healthy diets rich in plant-based foods and complex carbohydrates benefit the gut-brain axis, promoting mental well-being. Conversely, diets high in sugar and processed foods are linked to poor mental health. It emphasizes the role of bioactive compounds, circadian rhythm, and hormonal balance in brain health, providing insights into dietary strategies to prevent cognitive decline, depression, and anxiety.

This study investigated the effects of the MIND diet, a blend of Mediterranean and DASH diets, on cognitive function and brain structure in 37 healthy obese women over three months. Participants on the MIND diet, combined with calorie restriction, showed significant improvements in working memory, verbal recognition, and attention compared to a control diet. MRI scans indicated preservation of certain brain structures, suggesting neuroprotective benefits. These findings highlight the potential of the MIND diet to counteract obesity-related cognitive decline and improve brain health.

The research explores how dietary factors, including calorie restriction, intermittent fasting, polyphenols, and polyunsaturated fatty acids, influence brain plasticity in both animals and humans. These interventions improve markers like neurogenesis, synaptic function, and expression of neurotrophic factors, which are critical for learning, memory, and mood regulation. While animal studies show promising mechanisms, such as enhanced hippocampal function, human applications remain limited by translational gaps. This highlights diet as a modifiable tool for cognitive health.

This review discusses how diet and exercise interventions impact cognitive health and brain structure in older adults. It emphasizes the benefits of diets such as Mediterranean (MeDi), DASH, MIND, and weight-loss-focused approaches, highlighting their roles in reducing inflammation, oxidative stress, and supporting brain energy metabolism. Exercise modalities like endurance, resistance training, and yoga also improve cognition by enhancing brain vascularization and neuroplasticity. While evidence suggests these interventions help prevent cognitive decline, more targeted research is needed to identify the most effective strategies.

This systematic review assessed the MIND diet's influence on cognition in individuals across the dementia spectrum, including Alzheimer's disease (AD), mild cognitive impairment (MCI), and general dementia. The MIND diet combines elements of the Mediterranean and DASH diets, emphasizing leafy greens, berries, whole grains, and nuts while limiting processed foods and red meat. Studies revealed a positive correlation between adherence to the diet and improved cognitive performance, particularly in global cognition and executive function. However, results varied across cognitive domains, highlighting the need for further research to confirm these findings and refine applications for different populations.

This systematic review examined the effects of the Mediterranean Diet (MD) on cognitive function and dementia risk. The MD emphasizes fruits, vegetables, whole grains, olive oil, fish, and moderate alcohol intake. Across 32 studies, the MD was associated with better cognitive performance, reduced cognitive decline, and a lower risk of Alzheimer’s disease (AD) and mild cognitive impairment (MCI). The MD's benefits may stem from reduced inflammation, oxidative stress, and vascular risks. However, most evidence comes from observational studies, limiting conclusions about cause-and-effect relationships. Controlled trials are needed to confirm the MD’s role in brain health.

The Healthline article "Mediterranean Diet 101: A Meal Plan and Beginner’s Guide" provides an overview of the Mediterranean diet, emphasizing its focus on fruits, vegetables, whole grains, legumes, nuts, and healthy fats like olive oil. It suggests limiting red meat, processed foods, and added sugars. The article highlights potential health benefits, including weight management, heart health, and diabetes prevention. Regarding brain health, the article notes that the Mediterranean diet may benefit brain health and prevent cognitive decline. However, it does not provide specific details or evidence supporting this claim. Healthline is generally considered a credible source, but the lack of detailed evidence in this article suggests that while adopting the Mediterranean diet could be beneficial for overall health, its direct impact on brain health and cognitive performance is not thoroughly substantiated here.

This cross-sectional study examined how adherence to the MIND diet, which blends the Mediterranean and DASH diets, impacts muscle strength in older adults. Researchers assessed hand grip strength (HGS), a key measure of muscle function, among 3,181 Kurdish adults. Those adhering most to the MIND diet had significantly better HGS, indicating stronger muscles. Foods like leafy greens, whole grains, berries, and fish, rich in antioxidants and anti-inflammatory compounds, likely play a protective role. Conversely, an unhealthy diet high in processed foods was linked to weaker muscles. Since muscle health correlates with cognitive resilience, this study highlights the MIND diet's potential dual benefits for physical and cognitive health.

This study explored how adherence to the Mediterranean diet impacts mental and cognitive health, sleep quality, and quality of life among older adults in Sicily. Researchers found that individuals closely following this diet had lower odds of cognitive impairment and depressive symptoms and were more likely to report good quality of life and sleep quality. The Mediterranean diet, rich in fruits, vegetables, whole grains, fish, and olive oil, may promote brain health by reducing inflammation, enhancing brain plasticity, and supporting neurogenesis, crucial for cognitive resilience and successful aging.

This study explored the link between adherence to the MIND diet and cognitive performance using data from the Framingham Heart Study. Higher adherence to the MIND diet, rich in vegetables, berries, whole grains, and healthy fats, was associated with better global cognitive function, visual memory, and processing speed. MRI scans revealed a connection between higher diet adherence and larger total brain volume, but no link to specific brain regions or cognitive decline over time. The findings underscore the MIND diet’s potential in supporting brain health through its anti-inflammatory and neuroprotective properties. However, longitudinal effects remain unclear, highlighting the need for further research.

This study examined the association between adherence to the MIND and Mediterranean diets and the age of onset of Parkinson’s disease (PD). The researchers analyzed dietary patterns and disease data from 167 participants with PD. They found that higher adherence to the MIND diet correlated with a later onset of PD, particularly in women, where the delay could be up to 17 years. For men, the Greek Mediterranean diet showed stronger associations with delayed onset. The findings suggest that antioxidant-rich and anti-inflammatory foods like leafy greens, berries, and fish could play a role in delaying PD onset. These results highlight the potential of diet as a preventive measure, particularly in neurodegenerative diseases.

This community-based neuropathological study analyzed the relationship between adherence to the MIND diet and hippocampal sclerosis (HS), a condition involving severe neuronal loss and gliosis in brain areas linked to memory. Using data from 581 participants in the Rush Memory and Aging Project, researchers found that high adherence to the MIND diet was associated with a 69% lower likelihood of HS. Moderate adherence reduced the risk by 54%. These associations remained significant even after adjusting for genetic factors like APOE-ε4 and other brain pathologies. This suggests the MIND diet’s potential to protect hippocampal structure and reduce risks of memory-related decline in aging populations.

This study examined adherence to the MIND diet in 66 cognitively healthy Mexican older adults and its alignment with the diet's recommendations. The MIND diet focuses on brain-healthy foods like leafy greens, berries, nuts, and fish, while limiting processed and high-fat foods. Only 28% of participants met the recommended intake, with low consumption of foods like olive oil, red fruits, and fish. These gaps were attributed to the high cost of such foods in Mexico. However, participants consumed adequate amounts of affordable options like legumes and poultry. The study highlights the need to adapt dietary guidelines to regional and economic contexts for better adherence and cognitive health benefits.

This study examined the association between the MIND diet and parkinsonism in older adults, using data from the Rush Memory and Aging Project. Parkinsonism, which includes symptoms like tremors and slow movements, affects many older adults. The MIND diet, rich in vegetables, berries, nuts, and whole grains, was linked to a 13% reduced risk of developing parkinsonism per unit increase in diet adherence score. Participants who closely followed the diet also experienced slower progression of motor symptoms. The Mediterranean diet showed some protective effects, but the DASH diet did not. These findings suggest that the MIND diet may offer significant protection against age-related motor decline.

This study analyzed the association between adherence to the MIND diet and cognitive function in older adults. Using data from a large cohort, researchers found that individuals with higher MIND diet scores had better cognitive performance and slower decline, regardless of common brain pathologies like Alzheimer's-related changes. This suggests that the MIND diet may help build "cognitive resilience," allowing people to maintain mental sharpness even when brain conditions associated with aging are present.

This study explored the relationship between adherence to the MIND diet and cognitive health in participants from the UK Biobank. While the MIND diet, emphasizing vegetables, berries, nuts, and whole grains, has been associated with improved brain health in past studies, this research found limited evidence of such benefits in this population. Higher adherence to the diet correlated with slightly poorer cognitive performance on several tests and showed no significant overall reduction in dementia risk. However, a lower risk of dementia was observed among women who followed the diet. These findings highlight the complexity of dietary influences on cognitive health and the role of individual variability.

This study explored the perspectives of older adults and healthcare professionals on the Mediterranean diet (MD) and its connection to gut microbiota for healthy aging. While both groups recognized the health benefits of the MD, including cardiovascular improvements, awareness of its specific role in promoting a healthy gut microbiome was limited. The study highlighted misconceptions about the MD and barriers to adoption, such as cultural differences and accessibility challenges. Enhanced public and professional education is needed to clarify the role of the MD in gut health, cognitive function, and overall aging.

This randomized controlled trial explored the effects of a short-term MIND diet intervention on weight, metabolism, and brain structure in 37 middle-aged obese women. The study found significant improvements in weight, body fat percentage, waist circumference, and hunger-related hormones (leptin, ghrelin, GLP-1) in the MIND diet group compared to a control group. Despite these positive metabolic and anthropometric changes, there were no observable differences in brain structures between the groups. The results highlight the MIND diet's potential for weight management and metabolic health but not immediate effects on brain anatomy.

This randomized controlled trial investigated the effects of the MIND diet—a combination of the Mediterranean and DASH diets—on weight, hunger-related hormones, and brain structures in overweight and obese middle-aged women. Over three months, participants following the MIND diet experienced significant reductions in weight, body mass index, body fat percentage, waist circumference, and leptin levels, alongside increases in ghrelin and GLP-1 levels, compared to a control group. However, no significant changes in brain structures were observed between the groups. These findings suggest that the MIND diet may positively influence metabolic health, which is crucial for maintaining cognitive function and overall brain health.

This literature review evaluates the impact of the Mediterranean, DASH, and MIND diets on cognitive health, dementia, and Alzheimer’s disease (AD). Across 56 studies, higher adherence to these diets was generally associated with better cognitive function and reduced AD risk, especially for the MIND diet. The benefits stem from components like olive oil, green leafy vegetables, and berries, which are linked to improved brain function and reduced cognitive decline. The findings emphasize the role of dietary patterns in brain health, particularly in aging populations.

The Healthline article "The MIND Diet: A Detailed Guide for Beginners" introduces the MIND diet, a fusion of the Mediterranean and DASH diets, specifically designed to promote brain health and reduce the risk of neurodegenerative diseases like Alzheimer's. The MIND diet emphasizes the consumption of ten brain-healthy food groups: leafy green vegetables, other vegetables, nuts, berries (especially blueberries), beans, whole grains, fish, poultry, olive oil, and wine in moderation. It also advises limiting intake of five unhealthy groups: red meats, butter and margarine, cheese, pastries and sweets, and fried or fast foods. Studies suggest that strict adherence to the MIND diet correlates with a slower rate of cognitive decline and a significantly lower risk of Alzheimer's disease.Adopting the MIND diet can be a practical lifestyle change to enhance brain health and cognitive performance. By focusing on nutrient-rich foods that support brain function and minimizing those that may contribute to cognitive decline, individuals can proactively manage their cognitive well-being. Given Healthline's reputation for providing evidence-based health information and the supporting scientific studies referenced, these dietary recommendations are credible and actionable for those seeking to improve brain health.

This study analyzed the MIND diet's effects on brain health through gene expression changes in the prefrontal cortex. Researchers identified a transcriptomic profile of 50 genes associated with the diet. Higher MIND diet adherence correlated with slower cognitive decline and lower dementia risk, mediated by specific genes involved in neurogenesis, inflammation, and vascular health. These findings highlight how diet can influence brain molecular pathways, offering insights into dementia prevention and cognitive health improvement.

This review discusses the significant role of nutrition, particularly the Mediterranean diet, in reducing dementia risk and supporting brain health. The Mediterranean diet, rich in fruits, vegetables, whole grains, healthy fats, and moderate fish intake, is linked to slower cognitive decline and a lower risk of dementia. Its benefits may arise from improved vascular health, reduced inflammation, and positive impacts on the gut-brain axis. Promoting such dietary habits early in life can lead to long-term cognitive health benefits and reduced neurodegeneration risks.

This randomized controlled trial evaluated the effects of the MIND diet on preventing cognitive decline over three years in older adults with risk factors for dementia. While both the MIND diet and a control diet (with caloric restriction) improved cognitive scores slightly, there was no significant difference between groups in cognitive performance or brain imaging markers (e.g., hippocampal volume). The findings suggest that the MIND diet alone may not strongly impact cognitive decline in high-risk populations.
