Protein is a nutrient necessary for healthy functioning of your body. Protein is a structural component of many tissues and also works to keep your immune system strong. When dealing with cancer, your daily requirement for protein may be elevated, states the National Cancer Institute. However, the increase in your need for protein may present you with additional challenges. Your cancer treatment may leave you with temporary difficulty in chewing foods. Furthermore, you may notice a decrease in your appetite or in the way food tastes. During these times, protein powder may help you add this important nutrient to your diet to keep you well-nourished during your recovery.
Types
Protein powder originates from a variety of sources. Whey protein is a high-quality milk protein that your body digests and absorbs readily. Casein, another high-quality protein derived from milk, is digested more slowly than whey. Plant-based soy proteins offer a nutritionally complete protein comparable to milk proteins. Protein powders may also consist of a blend of two or more types of protein, often containing both milk and egg proteins. The protein powder you choose may depend on how your body reacts to a specific type of protein as well as personal preference.
Advantages
A big advantage of protein powders is the convenience they offer. Mixing protein powder with milk or juice, or blending it into a smoothie, requires little effort, an important consideration when your energy levels are low due to your illness. The ability to add significant protein to your diet in a liquid form may help you overcome digestive upsets or trouble with chewing or swallowing whole foods. Some protein powders may offer additional nutrients along with the protein they provide. Finally, protein powder mixed with liquid also helps to keep you hydrated as you recover from cancer.
Disadvantages
Protein powders are not all created equal when it comes to taste, so you may have to experiment with different flavors and brands before finding one you like. You may need to avoid milk-based protein powders if you are lactose-intolerant or egg-based proteins if you have an allergy to eggs. Because soy products may contain phytoestrogens, consult with your health-care provider to rule out contraindications with your specific type of cancer.
Other Considerations
Protein powders, when used on a regular basis, may become a significant expense in your food budget. If you are able to tolerate dairy products, nonfat powdered milk may prove an economical and nutritious substitute for commercial protein powders. Nonfat powdered milk may also offer a more natural taste than other available protein powders.
