Longevity Nutrition

Eating for healthspan and disease prevention.

Healthspan vs Lifespan

Lifespan: How long you live

Healthspan: How long you live well (healthy, functional, independent)

Goal: Maximize healthspan. Adding years of poor health isn't the win.

The Big Picture

What actually matters for longevity:

  1. Don't be obese (BMI <30, ideally <27)
  2. Don't smoke
  3. Exercise regularly (cardio + strength)
  4. Maintain muscle mass
  5. Eat mostly whole foods
  6. Don't drink excessively
  7. Manage stress
  8. Sleep 7-9 hours
  9. Maintain social connections

Nutrition is important, but it's one piece of a larger puzzle.

The Blue Zones

Blue Zones: Regions with the highest concentration of centenarians

The Five Blue Zones

  1. Okinawa, Japan
  2. Sardinia, Italy
  3. Nicoya, Costa Rica
  4. Ikaria, Greece

  • Inflammatory compounds (especially processed)
  • Saturated fat (in excess)

Evidence:

  • Processed meat (bacon, sausage, deli meat): Clearly linked to health issues
  • Red meat (beef, pork, lamb): Modest association with disease when consumed daily

Recommendation:

  • Limit red meat to 1-2 times per week
  • Choose grass-fed when possible
  • Avoid processed meats or minimize significantly

Added Sugar

The clearest villain in modern diet

Problems:

  • Obesity
  • Type 2 diabetes
  • Metabolic syndrome
  • Inflammation
  • Dental issues
  • No nutritional value

Recommendation: <25g (women) or <36g (men) per day from added sources

Worst offenders:

  • Soda and sweetened drinks
  • Candy
  • Baked goods
  • Sweetened yogurt
  • Breakfast cereals

Ultra-Processed Foods

What counts: Foods with ingredients you wouldn't have in your kitchen

Problems:

  • Engineered for overconsumption
  • Low nutrient density
  • High in sodium, sugar, unhealthy fats
  • Consistently linked to poor health outcomes
  • Displace whole foods

Examples:

  • Fast food
  • Packaged snacks
  • Frozen dinners
  • Sugary cereals
  • Most foods with >5 ingredients

Recommendation: <10% of diet

Excessive Alcohol

Nuance: Moderate may be okay (or even beneficial in some studies), but excessive is clearly harmful

Problems with excess:

  • Liver damage
  • Increased cancer risk
  • Empty calories
  • Impaired sleep
  • Addiction potential

Recommendation:

  • Women: ≤1 drink/day
  • Men: ≤2 drinks/day
  • Or less/none

Best choice if drinking: Red wine (polyphenols)

Consider: Zero alcohol may be optimal for longevity (recent research suggests even moderate drinking has risks)

Trans Fats

Avoid completely

Found in:

  • Partially hydrogenated oils
  • Some fried foods
  • Some baked goods

Clearly harmful, no safe level

Moderate Everything (Common Sense Approach)

Principles:

  • Mostly whole foods
  • Variety of plants
  • Quality protein sources
  • Healthy fats
  • Minimal processed food
  • Don't overeat

Not sexy, but works: Most longevity diets have more similarities than differences

Specific Longevity Compounds

Polyphenols

Antioxidant compounds in plants

Benefits: Anti-inflammatory, may protect against chronic disease

Top sources:

  • Berries
  • Dark chocolate
  • Green tea
  • Coffee
  • Olive oil
  • Red wine

Omega-3 Fatty Acids

Anti-inflammatory fats

Evidence: Heart health, brain health, reduced inflammation

  • Algae supplements (EPA/DHA for vegans)

Target: 1-3g EPA+DHA daily

Fiber

Feeds gut microbiome, improves metabolic health

Evidence: High fiber intake associated with reduced mortality

Target: 25-38g daily (most people get ~15g)

Sources: Vegetables, fruits, legumes, whole grains

Antioxidants (Vitamins C, E, Selenium)

Protect against oxidative stress

Best from food, not supplements (supplement studies often disappointing)

Sources: Colorful fruits and vegetables, nuts, seeds

Specific Diseases and Prevention

Cardiovascular Disease (Heart Attack, Stroke)

Leading cause of death

Dietary strategies:

  • Mediterranean diet
  • Minimize trans fats and excessive saturated fat
  • Eat fatty fish
  • Lots of vegetables and fruits
  • Whole grains
  • Limit sodium (<2,300mg)

Key nutrients: Omega-3s, fiber, potassium

Type 2 Diabetes

Dietary strategies:

  • Maintain healthy weight (most important)
  • High fiber
  • Limit added sugar and refined carbs
  • Whole grains over refined
  • Regular meal timing

Key nutrients: Fiber, chromium, magnesium

Cancer

Diet impact varies by cancer type

General strategies:

  • Lots of vegetables and fruits (especially cruciferous)
  • Limit processed meat
  • Limit red meat
  • Maintain healthy weight
  • Limit alcohol

Key nutrients: Fiber, antioxidants, folate

Cognitive Decline / Alzheimer's

Dietary strategies:

  • Mediterranean diet or MIND diet (Mediterranean-DASH Intervention for Neurodegenerative Delay)
  • Fatty fish
  • Berries
  • Leafy greens
  • Limit added sugar

Key nutrients: Omega-3s, B vitamins, vitamin E

Osteoporosis

Dietary strategies:

  • Adequate calcium (1,000-1,200mg)
  • Vitamin D (1,000-2,000 IU)
  • Protein (prevents muscle loss that protects bones)
  • Vitamin K (leafy greens)

Also: Strength training (not just nutrition)

Calorie Restriction and Longevity

The Evidence

Animal studies: Calorie restriction (20-40% reduction) extends lifespan significantly

Human studies:

  • Observational data supports moderate restriction
  • Controlled trials show health improvements
  • Lifespan extension not proven in humans (yet)

Practical Application

Don't chronically under-eat, but:

  • Don't overeat
  • Stop at 80% full (hara hachi bu)
  • Practice intermittent fasting (optional)
  • Avoid constant snacking
  • Be mindful of portions

Balance: Adequate nutrition for muscle mass and function vs avoiding excess

Fasting and Longevity

Potential Benefits

Theoretical mechanisms:

  • Autophagy (cellular cleanup)
  • Improved insulin sensitivity
  • Reduced inflammation
  • Metabolic flexibility

Evidence: Mostly animal studies, human data emerging

Practical Approaches

Intermittent Fasting (16:8):

  • Fast 16 hours, eat in 8-hour window
  • May support metabolic health
  • Helps control calories

Periodic Extended Fasts:

  • 24-72 hour fasts occasionally
  • More autophagy
  • Harder to maintain muscle

Reality: Long-term adherence matters more than perfect protocol

Supplements for Longevity

SupplementDoseEvidence
Vitamin D1,000-4,000 IUMost people deficient, crucial for bones, immune
Omega-3 (EPA/DHA)1-3gHeart health, brain function, anti-inflammatory
Magnesium200-400mgWidespread deficiency, multiple functions

Potentially Helpful

SupplementDoseNotes
Vitamin K2100-200 mcgBone and heart health, hard to get from food
B vitaminsB-complexEspecially B12 for older adults and vegetarians
ProbioticsVariesMay support gut health

Experimental / Unproven

  • Resveratrol (minimal human evidence)
  • NMN/NR (NAD+ boosters - early research)
  • Metformin (off-label, prescribed for diabetes)
  • Rapamycin (research stage, side effects)

Don't waste money on unproven longevity supplements. Focus on food and proven basics.

Protein for Aging

The Sarcopenia Problem

Sarcopenia: Age-related muscle loss (begins ~40, accelerates after 60)

Problems:

  • Weakness
  • Falls and fractures
  • Loss of independence
  • Metabolic decline

Protein Needs Increase with Age

Research suggests older adults need more protein:

  • Young adults: 0.8g/lb adequate
  • Older adults (60+): 1.0-1.2g/lb may be better

Why: Anabolic resistance (muscle less responsive to protein)

Strategy for older adults:

  • 30-40g protein per meal (not just 10-20g)
  • Strength training (essential to maintain muscle)
  • Adequate calories (under-eating accelerates muscle loss)

Longevity Lifestyle (Beyond Food)

Nutrition alone isn't enough

The Longevity Pyramid

Foundation (most important):

  1. Don't smoke
  2. Maintain healthy weight
  3. Exercise regularly (cardio + strength)
  4. Sleep 7-9 hours
  5. Manage stress

Next level: 6. Eat mostly whole foods 7. Lots of plants 8. Healthy fats 9. Adequate protein 10. Limit alcohol

Top level (nice to have): 11. Specific supplements 12. Fasting protocols 13. Tracking biomarkers 14. Optimizations

Don't obsess over level 3 while ignoring level 1-2.

Biomarkers to Track

Get these checked periodically (annually or as recommended):

TestOptimal RangeWhy
Blood pressure<120/80Cardiovascular risk
Fasting glucose<100 mg/dLDiabetes risk
HbA1c<5.7%3-month glucose average
LDL cholesterol<100 mg/dLHeart disease risk
