Phytochemicals are associated with diseases via the approach illustrated in Figure 4.

<p>For exemplary cancer types, we list the number of phytochemicals that are similar to small compound drugs that are approved for treatment of the disease (column 3), the number of phytochemicals that have experimental activity against a target implicated in this cancer type (column 4) and the corresponding number of common foods that contain these phytochemicals (column 5).</p><p>DOID: Human Disease Ontology Identifier.</p>1<p>from DRUGBANK.</p>2<p>from ChEMBL and TTD.</p>3<p>similar to a drug (with exp. disease-related target).
