Some proteins make more poison than others for sick livers
Amino acids, ammonia, and hepatic encephalopathy.

When the liver is sick, it can't clean up ammonia, a waste from breaking down protein. Too much ammonia hurts the brain. Some types of protein (amino acids) make more ammonia than others.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Excessive protein intake overwhelms hepatic urea cycle capacity, leading to systemic ammonia accumulation and subsequent metabolic toxicity.
Some types of protein building blocks (amino acids) make more ammonia than others when broken down — especially in people with liver problems.
We need a smarter way to give liver patients enough protein to stay strong, without making their brain fog worse.
When the liver can't clean out ammonia properly, it builds up in the blood and messes with brain function, causing confusion or drowsiness.
When people with liver problems eat protein, their bodies break it down into ammonia, which can build up and harm the brain.
