A multicenter study published in Nature earlier says diet may help limit the spread of triple-negative breast cancer, which is often deadly.
Triple-negative breast cancer cells grow and spread faster than other cancer cells. The researchers studied triple-negative breast cancer cells, which grow and spread faster than most other types of cancer cells. It is called triple negative because it lacks receptors for the hormones estrogen and progesterone and makes little of a protein called HER2. As a result, it resists common treatments—which target these factors and has a higher-than-average mortality rate.
Most tumor cells stays in the breast site, while some tumor cells leave and enter the bloodstream, colonize in the lungs, brain and liver, and proliferate.
The new study shows by limiting an amino acid called asparagine, the ability of such tumor cells to travel to other organs are greatly limited.
The study was carried on mice at more than a dozen institutions. The next step is to get confirmation on human cells.
What foods contain high asparagine, and what foods contain low asparagine?
Foods rich in asparagine include dairy, whey, beef, poultry, eggs, fish, seafood, asparagus, potatoes, legumes, nuts, seeds, soy and whole grains.
Foods low in asparagine include most fruits and vegetables.
So we know what we should eat.
