When you're feeling under the weather, your appetite often takes a nosedive. But that doesn't mean you can slack off on meals! For cancer patients especially, getting enough energy from food and protecting your muscles is super important. Spending a lot of time lying down can lead to significant muscle loss. For middle-aged individuals, this natural muscle decline can coincide with hospital stays, increasing the risk of sarcopenia. This condition can actually be more dangerous than the illness itself. That's why cancer patients are encouraged to eat protein-rich foods, including meat, as it's readily absorbed by the body.

Muscle Protein Loss in Cancer Patients and the Risk of Sarcopenia

According to data from the Korean Society for the Study of Obesity, cancer triggers the release of inflammatory cytokines, causing systemic inflammation that promotes the breakdown of fat and muscle protein. Consequently, patients may experience continuous loss of muscle mass even with adequate nutrition and insulin. Prolonged high blood sugar levels can lead to chronic inflammation and metabolic disturbances, which in turn hinder muscle protein synthesis and accelerate breakdown. During chemotherapy, side effects like nausea, vomiting, loss of appetite, diarrhea, and weight loss can occur, ultimately leading to malnutrition and sarcopenia. This can result in a decrease in skeletal muscle mass and a decline in physical function.

Nutritional Management for Hospitalized Patients: The Importance of Protein Intake

The nutritional guidelines for hospitalized patients emphasize that cancer patients need to eat well. It's advisable to monitor weight changes and provide high-energy-density foods and beverages as needed. Sufficient protein intake is crucial for aiding recovery and preventing muscle loss. A minimum of 1.0g of protein per kilogram of body weight per day is recommended, and ideally, this should be increased to 1.5g. If kidney function is not compromised, consuming up to 2g of protein per kilogram is generally safe. However, patients with acute kidney failure should not exceed 1.0g, and those with chronic kidney disease should stay within 1.2g.

What Kind of Protein Foods Are Best?

So, what protein foods should you choose? Generally, animal-based proteins are called complete proteins because they contain all essential amino acids. They are well-absorbed by the body, so beef, pork, chicken, fish, eggs, and dairy products are recommended. On the other hand, plant-based proteins like legumes may lack certain essential amino acids. If specific essential amino acids are deficient, protein synthesis in the body can become difficult. Therefore, it's best to consume plant-based proteins like beans and tofu in a balanced way alongside animal-based proteins.

Nutritional Supplementation: It's More Important Than Anything Else!

When eating meat, it's best to trim the fat and boil it. We can't serve burnt meat to patients with weakened immune systems. Don't forget that fish is also rich in protein. It's even better because it contains plenty of healthy unsaturated fatty acids. While mixed-grain rice is good, it can be hard on patients with poor digestion. In such cases, opting for white rice is a better choice. For patients, nutritional supplementation is paramount. Recovering their strength boosts immunity and enhances treatment effectiveness. Patients with a good appetite can build muscle and soon be walking the hospital corridors. To reiterate, the sicker you are, the more you need to eat well to recover quickly and get discharged sooner.
