Exposure to sugar rationing during the first 1,000 days of life is linked to a 19% reduction in all-cause mortality and a lower incidence of age-related disease, according to research published in Nature Communications.
Researchers analyzed data from 64,809 UK Biobank participants, taking advantage of Britain's postwar sugar rationing as a natural experiment to study long-term health outcomes. Individuals exposed to rationing during early childhood showed a 9% lower incidence of hallmark-related disease, corresponding to a hazard ratio of 0.91. For all-cause mortality, the hazard ratio stood at 0.81. Mediation analysis revealed that differences in incident hallmark-related disease statistically accounted for approximately 60% of the survival association.
Biological and Organ Ageing
Participants exposed to early-life sugar rationing measured 1.0 to 1.2 years younger in biological age across multiple biological clocks. These individuals also exhibited lower organ ages, with the strongest effects observed in the lung, heart, and liver. Proteomic profiling identified 47 altered proteins in rationed individuals, demonstrating enrichment of adenosine monophosphate-activated protein kinase and longevity pathways alongside suppression of mechanistic target of rapamycin signaling.
The authors noted that these findings align with limits on free or added sugars recommended by the World Health Organization, the United States Dietary Guidelines, and the American Heart Association. The findings may also inform policy discussions regarding sugar taxation and infant food marketing under the United Nations 2030 Agenda.
The study received support from the Guangzhou Municipal Research Fund under grant Z2023209, which played no role in the study design, data collection, analysis, or manuscript writing.
