There are no dietary restriction associated with the amyloidosis itself. However, since the amyloid attacks other body organs as a secondary effect, treating those might require diet & exercise therapy along with medication. For example, those with renal/kidney involvement may have to follow a diet that limits protein, sodium, potassium, phosphorus and fluids. When a patient has cardiac involvement, the situation is different and exercise may be more important. Generally, we recommend that you consult with your doctor. Blood tests will reveal what has to be managed. The doctor then should refer you to a dietician so that you can work out a plan.
