Can I eat peanut butter 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 0.58 mg per 100 g, peanut butter is moderate-to-high in copper, so portions are usually kept small and infrequent. 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.
