People with pulmonary nodules can eat peanuts in moderation if they are not allergic. Lung nodules are round-like shadows in the lungs up to 3 cm in diameter on imaging, and are associated with smoking, chronic inflammation, air pollution, and early-stage tumors. People with pulmonary nodules who are not allergic to peanuts in the past can eat peanuts without any special effect on the nodules themselves. However, peanuts should be consumed in moderation and reasonably combined with a variety of ingredients to achieve a balanced nutrition; and peanuts are high in fat, so those with high blood fat should limit their consumption. Patients with pulmonary nodules, regardless of whether they are in discomfort or not, need to go to a regular medical institution in time for further evaluation by a physician and dynamic observation or timely treatment according to the specific situation.
