Is the US egg-T2D association a causal effect of eggs or residual confounding by dietary pattern?
statement
The egg-T2D association reflects confounding by the co-consumed dietary pattern rather than a causal effect of eggs: in the US, egg intake marks adherence to a diabetogenic Western pattern (red/processed meat, refined grains, sugary drinks) that adjustment cannot fully remove, producing the positive association, whereas where eggs track prudent/traditional diets (e.g. Japan) the residual association is null-to-inverse.
Widened from the US-specific residual-confounding claim to the general dietary-pattern-marker claim covering both the US-positive and the non-US null-to-inverse associations; no curated observation discriminates the US-only version from the general one.
H-9 — Authors conclude the higher US risk “may not reflect egg consumption per se but rather egg consumption habits”.
