🍷 ¿El vino protege el corazón?❤️
Nuevo análisis del PREDIMED + SUN (Martínez-González MA et al. Eur Heart J 2026).
📊 7447 pacientes de alto riesgo CV (PREDIMED) + cohorte SUN.
🔎 En quienes seguían estrictamente la dieta mediterránea:
• Alta adherencia sin vino → ↓ 23% mortalidad total
• Alta adherencia + ≥7 copas/semana → ↓ 33% mortalidad total
Pero atención:
❗ El vino NO fue randomizado.
❗ Al cambiar el grupo de referencia (bebedores ligeros), varias asociaciones pierden significancia.
❗ No se replicó con la misma fuerza en la cohorte más joven (SUN).
❗ No hubo beneficio con ≥3 copas/día.
Posibles sesgos:
• Abstainer bias (ex bebedores enfermos en el grupo “no vino”).
• Residual confounding (estilo de vida, nivel socioeconómico, patrón cultural).
• Healthy user effect.
Mensaje real:
✔️ La dieta mediterránea sí tiene evidencia fuerte.
✔️ El vino moderado dentro de ese patrón no parece aumentar riesgo.
⚠️ No hay base sólida para recomendar iniciar consumo.
No es “el vino protege”.
Es “el contexto importa”.
