Abstract: According to an aspect of some embodiments of the present invention there is provided a computer-implemented method for selecting at least one nutrimer for a subject, the method being carried out by a nutrimer matching unit programmed to carry out the steps of the method, which comprise: receiving at least one genetic variation of a subject; automatically matching the at least one genetic variation with at least one nutrimer using a nutrimer correlation database storing a plurality of correlations of genetic variations with nutrimers; and generating a signal indicative of the at least one matched nutrimer.
