Can I eat crab with Wilson disease?

People with Wilson disease follow a low-copper diet, especially in the first year of treatment, because the body cannot clear excess copper normally. At 0.814 mg per 100 g, crab is a high-copper food that is normally kept off the plate. How strict your diet needs to be depends on your treatment stage and copper levels, so use this as a guide and confirm with your own clinician or dietitian.
