Sometimes finding the right diet that delivers proper nutrition during lung cancer treatment is a trial-and-error process. Talk to your doctor if you would like to see a registered dietitian nutritionist for nutritional guidance when you have lung cancer.
Each person's nutritional needs during lung cancer are different. They are based on your lung cancer treatment plan, your current height and weight, and any other illnesses you may have such as diabetes or heart disease. Here are some nutrition goals to keep in mind as you face lung cancer:

- Supplement with high-calorie drinks if necessary
- Use herbs and spices to make food more appealing
- Try liquid or pureed meals if you are struggling to eat
- Eat several small meals throughout the day
- Avoid food that is very hot or very cold
- Mint and ginger teas can help soothe your gut
- Do not take dietary supplements without consulting your doctor
- Eat sitting up. Do not lie down after eating
- Eat bland foods if your stomach is upset or your mouth hurts
- Eat high fiber foods to help relieve constipation
- Talk to your doctor!
