Diet Tips for Cancer Patients

Diet Tips for Cancer Patients

Eating properly is a key part of cancer treatment. The treatment itself may affect your appetite and can also alter your sense of taste and the body’s ability to absorb nutrients. During anti-cancer treatment, if you experience side effects or emotional distress, it may be difficult to eat enough. It is important to manage your emotions and maintain regular meals to keep up your strength. The main dietary goals during cancer treatment are to maintain your body weight and energy levels.


Where Does Nutrition Come From?
Each patient has different nutritional needs. Those who have trouble maintaining weight should consume more high-calorie and high-protein foods. Eating a small appetizer before meals or engaging in light exercise can help stimulate appetite and promote digestion. Enhancing the color, aroma, and flavor of dishes can also encourage eating. You may consider adding foods such as avocados, quinoa, and olive oil to increase calorie intake. It is recommended to include adequate dietary fiber, such as oatmeal and sweet potatoes, while reducing refined grains (patients with an artificial stoma should consult their healthcare provider first).

The main nutrients in food include protein, carbohydrates, fat, water, vitamins, and minerals.

Protein
Protein helps repair body tissues and keeps the immune system healthy. Without enough protein, your body will take longer to recover from illness and fight infections. Cancer patients often require more protein than healthy individuals. Good sources of protein include lean meats, fish, poultry, dairy products, nuts, dried beans, peas, lentils, and other soy products. Carbohydrates and fats provide most of the calories your body needs. The amount of calories you require depends on your age, weight, and level of physical activity. Sources of carbohydrates include fruits, vegetables, whole-grain bread, pasta, cereals, oats, dried beans, peas, and lentils. Sources of fat include nuts, seeds, meats, fish, poultry, and other animal fats.

Vitamins and Minerals
These nutrients are essential for the body’s recovery. People who eat a balanced diet usually get enough vitamins and minerals. However, during cancer treatment, maintaining balance may be difficult. You should consult your doctor or a nutritionist to determine whether you need vitamin or mineral supplements. If you are taking vitamins or herbal supplements, please consult your healthcare team before continuing.

Water and Other Healthy Drinks
Fluids are vital for maintaining health. Inadequate fluid intake, or fluid loss from vomiting or diarrhea, can quickly lead to discomfort. Foods such as gelatin and applesauce also count as fluids and may be easier to consume than plain water. Ask your doctor or nurse how much fluid you should drink daily to replace the amount lost through sweating, vomiting, or diarrhea.


Key Principles for a Balanced Diet
Refer to the following guidelines to understand the recommended daily intake for a healthy person. Unless your specific needs differ, you should generally follow these:
• Eat at least 300–500 grams of vegetables and 200–350 grams of fruits each day
• Choose whole grains and limit processed grains and foods high in sugar
• Eat less processed meat (such as cured meat, sausages, or hot dogs) and red meat (beef, lamb, pork)
• Focus on plant-based food sources such as fruits, vegetables, nuts, beans, soy products, whole-grain pasta, and cereals
• If you drink alcohol, limit your intake and ask your doctor whether alcohol may affect your treatment

However, remember that the nutritional needs of cancer patients may differ from those of healthy individuals, especially during treatment. At this special time, please discuss your specific dietary needs with your doctor or nutritionist.
