Following a special diet may reduce the spread of triple− negative breast cancer, a new study published in the journal Nature has found. Triple–negative breast cancer cells lack receptors for oestrogen and progesterone and have low levels of HER2, making the cancer resistant to common
treatments which target these factors. But researchers found limiting an amino acid called asparagine in mice through diet drastically reduced the ability of the cancer to spread to other sites in the body. Foods rich in asparagine include dairy, beef, eggs, fish, asparagus and wholegrains, while foods low in the amino acid include most fruit and vegetables. Researchers say the study may be able to be used not just in breast cancer treatments but for many metastatic cancers.
