Lean Proteins
Protein provides amino acids that are necessary for the body to produce white blood cells. Ideally, you should go for lean sources, such as beans, lentils, skinless poultry, and seafood. Aim for 0.8 to 1g of protein each kg of the body weight on a daily basis. Avoid consuming deli or processed meats as they can be harmful to your health and immune system. Those people with cancer and are undergoing cancer treatments should take more protein than usual. [15]
