If you have cancer or know someone who has cancer, you may have heard that it is important to eat protein-rich foods. Did anyone ever tell you why?
Just in case you didn’t get an explanation, here’s a little background information.
In a nutshell, cancer can cause changes in protein metabolism. This may mean that your muscles start getting smaller, and you may need to take in more protein than before to keep this from happening. However, while you may hear an emphasis on protein, you should also know that non-protein calories such as carbohydrates and fats are important also. If you aren’t eating enough to meet your body’s energy needs, the cancer starts to use your body’s available protein for fuel. If this happens, your nutrition status will deteriorate, and your immune system will weaken.
So, what can you do to prevent this? Make sure you are eating a balanced diet that includes protein as well as carbohydrates and fats. One way to estimate if you are eating enough is to monitor your weight.
