Blue Zones for Brain Health: What to Keep, What to Question

Blue Zones are fascinating, but they are not a prescription. We explain what the data can (and cannot) prove, then turn a few key principles into practical brain-health strategies—satiety, food choices, alcohol clarity, and Singapore’s lesson: environment beats willpower.

In this episode, we unpack:

• What Blue Zones are, why they became popular, and why observational data is not the same as proof.
• The nine Blue Zones principles—and which ones matter most for brain health in real life.
• The 80% rule (Hara Hachi Bu): why it is hard to measure, and how to build awareness without shame.
• Practical behaviour design for food choices (including the bread basket problem and reducing mindless snacking).
• “Set up, skill up, speak up”: using environment, skills, and family conversations instead of willpower.
• Plant-forward eating without making animal foods “good” or “bad,” plus shortcuts that support follow-through.
• “Wine at five”: what we disagree with, what the evidence suggests, and why timing and context matters.
• Singapore as a modern Blue Zone example—and what it teaches us about making healthy choices easier by design.

KEY TAKEAWAYS

What “Blue Zones” Means

• Journalist Dan Buettner mapped places with unusually high numbers of people living past 100.
• Locations: Icaria (Greece), Sardinia (Italy), Loma Linda (California), Nicoya (Costa Rica), Okinawa (Japan), and Singapore (added 2023)
• The findings are observational (patterns noticed), not proof of cause and effect.

The 9 Blue Zones Principles

1. Move naturally
2. Downshift (reduce stress)
3. Belonging (faith or community)
4. Right tribe (supportive friends)
5. Loved ones first
6. 80% rule (stop eating when lightly full)
7. Plant slant (more vegetables)
8. Wine at five
9. Know your purpose

80% Rule (Hara Hachi Bu)

• Aim to stop eating when you feel slightly full.
• Eat protein first; it helps you feel satisfied longer than carbs.
• At restaurants: say “no, thank you” to the bread basket or keep it off the table.
• After each meal: ask, “How full am I?” and give yourself a simple rating.
• Skip shame. If you eat past 80%, notice it and learn; do not judge.
• If you snack, ask, “Why am I eating?” (bored, stressed, hungry or habit) and adjust.

Design Your Environment (Set up, Skill up, Speak up)

• Set up: keep tempting foods out of the house; stock foods that fit your plan.
• Skill up: learn 1–2 fast recipes; repeat them until easy (sheet pan, slow cooker)....
