Nut Consumption and Prevention of Non-communicable Diseases: A Global Individual Participant Data Meta-analysis
Source: ClinicalTrials.gov · Last updated 20 Mar 2026
Brief summary (registry, in English)
The relationship between nut consumption and the risk of developing non-communicable diseases (NCDs) has been a subject of growing interest. However, the findings from previous studies have been conflicting for some health outcomes, such as type-2 diabetes, and have been underexplored for other outcomes, such as neurodegenerative diseases. One contributing factor to these inconsistencies lies in the different analytical approaches and confounding factors used across studies. Furthermore, the majority of previous studies have primarily focused on populations in Europe or the United States, potentially limiting the generalizability of the findings to other global regions. The NUTPOOL project aims to address these gaps by conducting an extensive individual participant data (IPD) meta-analysis. This study will evaluate the association between total and specific types of nut consumption and the future risk of NCDs.
