Method and system for characterizing diet-related conditions

A method for characterizing a diet-related condition, the method comprising:

• collecting biological samples from a set of users, wherein the biological samples comprise microorganism nucleic acids associated with the diet-related condition;
• generating a microorganism sequence dataset for the set of users based on the microorganism nucleic acids;
• determining microbiome composition diversity features and microbiome functional diversity features for the set of users based on the microorganism sequence dataset;
• collecting supplementary data associated with the diet-related condition for the set of users;
• transforming the supplementary data, the microbiome composition diversity features, and the microbiome functional diversity features into a diet-related characterization model for the diet-related condition;
• generating a diet-related characterization for a user based on the diet-related characterization model;
• and
• promoting a health-supporting measure to the user with the diet-related condition based on the diet-related characterization.
