Nut Consumption and Prevention of Non-communicable Diseases: A Global Individual Participant Data Meta-analysis
This is not a clinical trial in the usual sense. It is a large-scale data analysis project called NUTPOOL that will pool raw data from many existing long-term diet studies around the world. Researchers want to understand whether eating nuts regularly is linked to lower risk of diseases like dementia, diabetes, heart disease, and cancer. No intervention is being tested on participants directly. Details on phase are unspecified because this is observational research, not a drug or treatment trial.
