Cocoa flavanols may offset sitting's harm to blood vessels

Cocoa flavanols may block sitting's negative effects on blood vessels, per new research.

Why it matters

  • Sitting harms blood vessels, raising heart disease risk.
  • Cocoa flavanols may block these effects.

By the numbers

  • 40 healthy young men studied.
  • High-flavanol drink: 695 mg flavanols.
  • Low-flavanol drink: 5.6 mg flavanols.

The big picture

  • Sitting increases obesity, diabetes, and muscle loss risks.
  • Dietary changes could help mitigate sedentary lifestyle effects.
  • Flavanols found in cocoa, fruits (apples, berries), nuts, teas, and vegetables.

What they're saying

  • Some commenters skeptical about practicality.
  • Concerns about heavy metals in cheap cocoa.

Caveats

  • Small study (40 men), short duration (2 hours).
  • Effects seen in young, healthy men may not generalize.

What’s next

  • Combining flavanol-rich foods with activity breaks may improve long-term health.
