A study found that mice with liver cancer who ate less protein lived longer and had slower tumor growth. This could help people with liver disease or damage reduce their risk of developing liver cancer.

Eating a diet low in protein may be a simple way to slow the growth of liver cancer, according to a new study. Researchers at Rutgers University found that mice with liver tumors who were fed less protein lived longer and had slower tumor growth than those who ate normal amounts of protein.

The study's senior author, Wei-Xing Zong, explained that when the body breaks down protein, it produces ammonia, which is toxic to both the brain and the body. Normally, the liver converts this ammonia into a safer compound called urea, but in people with liver disease or damage, this process can be impaired.

The researchers found that mice who could not properly process ammonia accumulated higher levels of the toxin and developed larger tumors. They also discovered that excess ammonia was being incorporated into compounds that cancer cells rely on to grow and multiply.

To test whether lowering protein intake could reduce ammonia buildup, the team fed some mice a low-protein diet. The results were dramatic - these mice had significantly slower tumor growth and survived much longer than those who ate normal amounts of protein.

The findings may be important for people with liver disease or damage, as high protein intake can contribute to ammonia buildup. However, for people with healthy livers, high protein intake is generally not a concern.

The study's lead author, Xinlu Han, said that the results establish a link between nitrogen overload and liver cancer development and highlight protein restriction as a feasible therapeutic strategy for patients with impaired nitrogenous waste handling.

Why It Matters

This study may help people in India who are at risk of developing liver cancer due to liver disease or damage. A low-protein diet could be a simple way to reduce this risk, especially for those who already have liver conditions.

Key Facts

• The study found that mice with liver tumors who ate less protein lived longer and had slower tumor growth than those who ate normal amounts of protein.
• When the body breaks down protein, it produces ammonia, which is toxic to both the brain and the body.
• In people with liver disease or damage, the process of converting ammonia into urea can be impaired, leading to ammonia buildup.
• The study suggests that a low-protein diet could reduce ammonia buildup and slow liver cancer growth in people with liver disease or damage.
• For people with healthy livers, high protein intake is generally not a concern.
