Bodybuilding Mom of 2 Reportedly Dies of Protein Overdose
Hefford was found unconscious in her apartment on June 19 and rushed to the hospital, where it took doctors two days to diagnose her with urea cycle disorder. By that point, the buildup of ammonia in her blood and fluid in her brain was too much, and she was declared brain dead the next day.
The article doesn't say how much protein she consumed. A Urea Cycle Disorder is a rare genetic disease, which according to
Wikipedia means: "If individuals with a defect in any of the enzymes used in the cycle ingest amino acids beyond what is necessary for the minimum daily requirements the ammonia that is produced will not be able to be converted to urea." So I don't think this is something that people in general need to worry about.
