Proposed anti-aging dietary score linked to lower PhenoAge acceleration in NHANES
The authors propose the Nutrient-Signaling-Senescence axis as a framework and develop an anti-aging dietary score (AADS). In preliminary validation with NHANES data, a higher AADS was significantly associated with lower PhenoAge acceleration, similar to established indices. [1]

Proposed NSS framework for diet and aging biology
Conventional dietary indices often do not align with aging biology, according to the authors. To address this mechanistic gap, they propose the Nutrient-Signaling-Senescence (NSS) axis as an integrative framework. On this basis they develop the anti-aging dietary score (AADS). The framework is a proposal, not a validated product.

Higher AADS and lower PhenoAge acceleration in NHANES
Preliminary validation using NHANES data showed that a higher AADS was significantly associated with lower PhenoAge acceleration. The score performed comparably to established indices. This is an association, not evidence that the diet causes slower biological aging.

Aim to translate aging biology into population research
According to the authors, the framework enables translating aging biology into population-based research. The abstract reports only preliminary validation; details of the NHANES sample, dietary measurement, comparison and follow-up are not given.

How to interpret this
Abstract only; the full text was not reviewed. The validation is described as preliminary, and the abstract gives no sample size, dietary measurement details, comparison details or follow-up. The reported link is an association, not causation.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
