Doubts about the conclusion that patients with rheumatoid arthritis who receive medical nutrition therapy show orthorexic tendencies

In a recently published article, Sifakaki and colleagues conclude that patients with rheumatoid arthritis who receive medical nutrition therapy show orthorexic tendencies (i.e., a pathological preoccupation with healthy, “pure” eating that is associated with restrictive dietary patterns and nutritional deficiencies). This commentary argues that this conclusion is unwarranted based on the instrument used for measuring orthorexic tendencies, its scoring procedure, and—ultimately—its interpretation.
