When we think about cancer treatment, diet isn’t usually the first thing that comes to mind. But a new study from Rutgers University suggests that reducing protein intake might help slow liver cancer, especially in people with damaged livers.
How Protein Intake Affects Liver Cancer
Here’s the idea: when our bodies break down protein, they produce ammonia, a toxic byproduct. Normally, the liver quickly converts ammonia into a safer compound and removes it from the body.
But when the liver is already damaged (due to conditions like fatty liver disease, hepatitis, or cirrhosis) it may struggle to clear that ammonia properly.
Researchers found that excess ammonia can actually feed tumor growth, helping cancer cells produce the building blocks they need to multiply.
Study Findings
In experiments with mice, the results were striking. Animals that couldn’t process ammonia efficiently developed larger tumors and died sooner. But when researchers reduced the amount of protein in their diet, ammonia levels dropped, tumor growth slowed, and survival improved significantly.
For people with healthy livers, high protein intake generally isn’t an issue. But for those with existing liver disease, dietary protein levels could play a bigger role in cancer risk and progression than previously thought.
What This Means for Liver Cancer Treatment
Researchers stress that dietary changes should always be discussed with doctors, especially for cancer patients, who often need protein to maintain strength during treatment.
Still, the findings highlight something important: sometimes small metabolic changes in the body can have surprisingly big effects on disease.
If something as simple as adjusting protein intake can influence how tumors grow, should nutrition play a bigger role in how we approach cancer prevention and treatment?
