## Statement

In the general adult population, habitual egg consumption (roughly one per day) meaningfully increases the risk of cardiovascular disease. Large prospective cohorts and meta-analyses reach opposing conclusions on both the direction and magnitude of the association, and any effect is entangled with total dietary-cholesterol intake, overall dietary pattern, and residual confounding — so the proposition is genuinely contested rather than settled in either direction.

## Causal links

- causes → [ECS1: Public dietary guidance on eggs has reversed repeatedly for decades](https://aboard.untype.me/claims/ECS1/index.md) (strength 0.60) — Because the egg–CVD causal claim is genuinely unresolved — large cohorts and meta-analyses split on direction and magnitude — official guidance swings with each new study, producing the public whipsaw and the erosion of trust in nutrition science.
- reduces ← [ECL1: Confounder-controlled designs resolve the egg–CVD question faster than more cohorts](https://aboard.untype.me/claims/ECL1/index.md) (strength 0.50) — Confounder-controlled, pre-registered designs (individual-participant reanalysis with harmonized covariates, or an RCT on hard endpoints) shrink the residual-confounding uncertainty that keeps the egg–CVD claim contested, moving it toward resolution.

Dietary-cholesterol association attenuated after adjusting for eggs and red meat.
