Maintaining a healthy weight during Lung cancer treatment is very important. It is important to consume enough calories, proteins, and nutrients during cancer treatment to avoid weight loss. The four most important nutrition issues during cancer treatment are addressed in the following tips.

1. Decreased AppetiteRather than three regular-sized meals, eat small meals or snacks that are high in calories and protein several times throughout the day. Eggs, meats, poultry, fish, beans, legumes, nuts, and milk products are all high in protein.
2. FatigueIf preparing food is tiring, have easy to prep snacks like yogurt, cereals, soup, fruits, pudding, crackers with peanut butter or cheese, and sandwiches.
3. Weight LossIf you are experiencing nausea, bland foods that are low in odor are generally tolerated well.
4. Dehydration
Drink at least 8 to 10 cups of hydrating fluids daily.

Advice on Antioxidants, Vitamins, and Supplements

• Instead of taking supplements, try to get all of your nutrients from your food. Take a vitamin only if your doctor suggests it.

• Eat a variety of fresh fruits, vegetables, and whole grains, as many of them are high in antioxidants.

• If you smoke, avoid taking beta-carotene.

 Nutrition and Lung Cancer Side Effects 

If you are experiencing lung cancer side effects, you may need to change your diet. Always inform your doctor if you are experiencing any side effects. Take the following steps:

•  Eat a bland diet, eat small meals frequently, and add healthy fats to pack more nutrients into what you can eat to help with digestive side effects.

• Use a straw to help with mouth sores, and avoid foods that are too hot, cold, spicy, or acidic. 

• Request a referral to a palliative care team, which consists of healthcare professionals who specialise in assisting patients with side effects management. 

Getting Help 

Dietary changes can be challenging, but there are resources available to assist you. Take the following steps:

• Request a referral to a cancer-specialized registered dietitian.

• Get nutrition advice from the members of Inspire's Lung Cancer Survivors Community. Visit to get started.  Visit for more information. 

A modified version of the USDA’s MyPlate icon could guide you on nutritional intake. Instead of splitting your plate down the middle with protein and carbohydrates occupying one side and fruits and vegetables on the other — you should aim for a “peace sign” consisting of equal portions of fruits and vegetables, carbohydrates, and lean protein. 

Increased protein intake is beneficial for cancer patients because adequate protein intake is especially important to prevent losing lean muscle mass when losing weight.
