Do high protein diets lead to protein buildup in your heart (amyloidosis)?

No: Amyloidosis is indeed an abnormal build-up of proteins in the tissues which can contribute to a number of problems including cardiomyopathy. It has a number of different causes, including genetics, chronic inflammation, and neoplastic/cancerous causes. The proteins are being made by the person's own cells, and are not directly coming from the diet.

Diet: Amyloidosis is not a diet related condition. It is a genetically mediated condition and can also be related to protein production triggered by certain malignancies.

Amyloid : Is not related to dietary intake.
