Adding eggs to the diet raises LDL cholesterol compared to a no-egg diet.

Triggered by the specifying subclaim (egg-driven LDL increases smaller under substitution than addition) receiving its first assessment, SUPPORTED. This is a confirming change: the subclaim locates the largest LDL effect in exactly the additive contrast this parent claim states, reinforcing rather than challenging it. Verdict held at SUPPORTED, confidence firmed slightly (0.78 to 0.80, credence 0.80) to reflect the now-confirmed supporting structure; its SUPPORTED (not verified) standing kept the firming small. Also closed a gap: both named arguments lacked evaluations, so recorded them, the 'for' argument as holds (leaning on the well-established pooled RCT finding), the 'against' mechanism argument as holds_with_caveats (it reframes mechanism and caps magnitude but does not reverse the additive sign, keeping the parent supported not contested). Importance left at 0.4: a moderately live nutrition claim whose additive direction is fairly settled in the RCT literature. No web search needed; verdict stable and well-reasoned. No dependent notification: no material status or direction change.

Reassessed (status unchanged)
Triggered by subclaim_change: the mechanism subclaim (LDL effect driven by saturated fat, not dietary cholesterol) was formally assessed SUPPORTED (0.75). Re-judged the parent and found the change immaterial to its status. The subclaim contradicts the cause and bounds the magnitude/generality of the effect, but not the sign of the parent's additive comparison; adding eggs still adds a small amount of saturated fat and cholesterol, so a modest LDL rise remains expected. The prior assessment had already reasoned through the 2025 isolation trials, so the subclaim's verdict confirms rather than alters the treatment. Ran one web search to confirm no newer meta-analysis reverses the pooled additive sign; found the 2025 AJCN (Carter) and companion RCT, both mechanism studies consistent with the existing reasoning. Kept status SUPPORTED, confidence 0.78, credence 0.78. Importance left at 0.4 (notable/major nutrition claim, moderately contested and consulted; single local dependent on CVD risk). No structural change; decomposition remains apt. No dependent notification: parent status and credence unchanged, so the one dependent (egg consumption and CVD risk) has nothing new to triage from here.

Structured and assessed
First pass. Decomposed into the two pre-existing for/against arguments and gave both written forms. For the "RCT evidence" (for) argument: created new subclaim "Meta-analyses of RCTs find egg consumption modestly increases LDL cholesterol" and linked existing claim f4110516 (addition vs replacement) via specifies. For the "mechanism attribution to saturated fat" (against) argument: created new subclaim "Eggs' LDL-raising effect is caused by saturated fat, not dietary cholesterol" and linked existing claim 06290879 (dietary cholesterol weak/variable effect) via contradicts. Ran match_claim on all four candidates; all novel, but two strong existing neighbors were linked rather than duplicated. Set importance 0.4 (notable/major nutrition biomarker premise; direction settled, mechanism/magnitude contested). Assessed SUPPORTED (confidence 0.78, credence 0.8): large consistent RCT meta-analytic base supports a modest LDL rise in the additive comparison; newer isolation trials reattribute the cause to saturated fat and show context-dependence but test a different comparison, so they bound magnitude/mechanism rather than reverse the direction. Web search used for external evidence (multiple RCT meta-analyses and 2025 AJCN isolation trials).

In the comparison this claim describes, eggs added to an otherwise unchanged diet versus no eggs, the weight of controlled evidence favors a modest rise in LDL cholesterol. Meta-analyses pooling dozens of randomized feeding trials consistently report a small but statistically significant LDL increase with egg consumption, on the order of a few milligrams per deciliter, and the increase is largest precisely in this additive setting rather than when eggs displace other foods. The effect is genuinely modest, and its cause is the subject of live scientific debate. A newer set of trials designed to separate egg cholesterol from the saturated fat that usually accompanies it points to saturated fat as the real driver of LDL: in these studies dietary cholesterol from eggs had little independent effect, and eggs eaten as part of a low-saturated-fat diet did not raise, and in one trial even lowered, LDL. That work does not overturn the additive finding, which involves adding eggs without otherwise adjusting the diet, but it shows the effect is small, mechanism-dependent, and can vanish or reverse once saturated fat is held constant. The direction of the effect in the stated comparison is therefore well established; the open questions concern its magnitude, its mechanism, and how much it matters for health rather than whether adding eggs nudges LDL upward.
