Cutting down on red meat, eggs could aid cancer treatment, new study finds
- The study found that restricting intake of an amino acid found in red meat and eggs boosted cancer treatment in mice, slowing tumour growth
- It suggests there may be situations where a drug by itself doesn’t work, but does when combined with an appropriate diet
Diet is already a key part of managing diseases such as diabetes and hypertension, but new research adds to a growing body of evidence that it could help cancer treatment, too.
The study, published last month in the journal Nature, found restricting intake of an amino acid found in red meat and eggs significantly enhanced cancer treatment in mice, slowing tumour growth.
“These are very strong effects, and they are effects that are as strong as we would see with drugs that work,” said lead researcher Jason Locasale, an associate professor at Duke University’s School of Medicine in the US state of North Carolina.
“What this study is showing is that there are many situations where a drug by itself doesn’t work, but if you combine the drug with the diet, it works, or the radiation therapy doesn’t work well, but if you combine … with the diet, it works well,” he said.
The study focused on restricting intake of the amino acid methionine, which is key to a process called one-carbon metabolism that helps cancer cells grow.
