Is it safe for gout patients to eat Chinese yam?

Patients with gout can consume Chinese yam (Dioscorea opposita). Gout is a crystalline arthritis caused by hyperuricemia; therefore, individuals with gout must restrict their dietary purine intake. During the acute phase, patients are advised to consume low-purine foods, whereas during the chronic or intercritical phases, moderate-purine foods may be consumed in moderation. Chinese yam is classified as a low-purine food, containing approximately 10 mg of purines per 100 g.
