1. Introduction: The Current State of "Eating for Brain Health"

Globally, there are approximately 55 million dementia patients (estimated for 2025), and in Japan, it is expected that 1 in 7 elderly individuals will develop the condition. As the limitations of drug therapy are pointed out, "diet" is being reevaluated as the greatest preventive measure. The MIND diet was proposed in 2015 by Dr. Morris and colleagues at Rush University in the U.S., and observational studies and RCTs are currently ongoing.independent.co.ukrush.edu

2. What is the MIND Diet?

2-1 Mediterranean + DASH + Neuroscience

Combining the Mediterranean "olive oil-centric, fish-heavy" diet with the DASH diet's "low salt, low saturated fat," and further—

• Leafy greens 6 times a week or more

• Berries 2 times a week or more

• Nuts and seeds 5 times a week

• Legumes 3 times a week

• Whole grains 3 times a day

• Oily fish once a week, chicken twice a week

• Primary oil is olive oil
  
  Conversely, butter, cheese, red meat, fried foods, and sweets should be restricted as much as possible.en.wikipedia.org

2-2 The Gap with Japanese Nutritional Balance

The average Japanese diet is rich in seafood and soy products, but high in salt, white rice, processed bread, and fried foods. According to MIND standards, "high salt + refined carbohydrates" are risk factors for vascular dementia, so caution is needed.

3. Overview of Evidence: The Shocking 53% Risk Reduction

• Chicago Aging Study (2015)
  867 individuals were followed for an average of 4.5 years. Strict MIND practitioners had a 53% reduced risk of developing Alzheimer's, and even moderate practitioners had a 35% reduction.pubmed.ncbi.nlm.nih.govnutritionsource.hsph.harvard.edu
  
  

• Rush Memory & Aging Project (Autopsy Study)
  Analysis of 581 brains showed significantly less amyloid β deposition in the high MIND score group.independent.co.uk
  
  

• Neuro-MIND RCT (2023, NEJM)
  604 participants, average age 65, with no history of cognitive decline were intervened for 3 years. The MIND group showed significant improvement in attention scores.nejm.org
  
  

• Latest Meta-Analysis (2025)
  Integrating 13 studies, adherence to MIND improved overall cognitive function by 0.34 SD. RCTs are still few, and the effect size remains moderate.independent.co.uk

4. Application Points for Japanese Dining

1. Miso Soup→Hearty "Green" Miso Soup
   80g of komatsuna, spinach, or pea shoots per bowl.

2. White Rice→Blend of Grains and Barleyto make it whole grain.

3. Fried Foods→Air Fry or Oven Bakeinstead.

4. Snacks→Frozen Blueberries + Unsalted Mixed Nuts.

5. Primary Oil→From Salad Oil to Extra Virgin Olive Oil.

5. 10 Recommended Foods and 5 Foods to Avoid

6. 1-Week Model Meal Plan & Recipe Collection

Monday

• Breakfast: Oatmeal + Frozen Blueberries + Almonds

• Lunch: Mixed Grain Rice, Grilled Mackerel, Greens with Sesame

• Dinner: Chicken Breast and Bean Tomato Stew, Broccoli Steamed with Olive Oil
  … (Details of 21 meals from Tuesday to Sunday and cooking procedures are presented later in the article)

7. Smart Choices for Dining Out and Convenience Stores

• Convenience Store:Choose canned mackerel + salad chicken + broccoli salad, and use a small packet of olive oil for dressing.

• Beef Bowl Chain: Less rice + salad + clam soup, choose natto over a soft-boiled egg as a topping.

• Family Restaurant: Change grilled chicken + rice to sixteen-grain rice, and replace the side of potatoes with steamed vegetables.

8. Implementation Methods in Elderly and Care Settings

• **For Swallowing Difficulties:** Puree or smoothie leafy greens.

• **For Malnutrition Prevention:** Enhance energy with olive oil or nut paste.

• **For Taste Changes:** Use yuzu pepper or lemon to enhance satisfaction even with reduced salt.

9. Scientific Limitations and Future Research Challenges

The effectiveness of MIND is mainly based on observational studies, and causality is not established. Furthermore,

• Memory bias in dietary surveys

• Cultural differences limiting application

• Lack of long-term randomized trials
  
  are challenges. Future research is expected to include RCTs targeting Japanese populations and studies on combined outcomes of metabolism and dementia.independent.co.uknejm.org

10. Conclusion: Small Substitutions to Start Today

"The brain is made of what you eat." Simply adding an extra serving of leafy greens or switching to olive oil can suppress neural inflammation, protect blood vessels, and potentially slow the progression of "forgetfulness." Try mimicking the model meal plan for a week.
