Here’s a summary with bullet points and quotes from “The Best Foods for Healthy Longevity—According to Harvard” by Heather Hurlock (April 3, 2025):
🧬 Key Study Highlights
-
A 30-year study in Nature Medicine followed 100,000+ people to understand how midlife diet affects health in later years.
-
Only 9.3% of participants aged into their 70s with no chronic disease, good physical and cognitive function, and stable mental health.
-
Those who did shared one common trait: long-term, consistent healthy eating.
“People who followed the AHEI closely were 86% more likely to reach age 70 in good health—and more than twice as likely to still be thriving at 75.”
🥗 The Star Diet: AHEI (Alternative Healthy Eating Index)
-
Plant-forward, flexible (not restrictive or trendy).
-
Includes fish, dairy, and healthy fats.
-
Emphasizes patterns over perfection—it's about consistency, not rigid rules.
“It’s not only about living longer, but being able to live longer with better health.” – Dr. Marta Guasch-Ferré
💡 What’s Old but Reinforced
-
Ultra-processed foods & sugary drinks? Still bad.
-
Fruits, veggies, legumes, and whole grains? Still essential.
-
Red meat and sodium? Keep it minimal.
-
The difference is data-backed confirmation over decades.
“We’re not talking about vague advice or short-term trials. This is real-life, long-haul evidence.”
