Pulmonary nodules can be either small lesions on lung imaging or pulmonary nodular disease associated with immune dysfunction. However, in either case, fruit is only one type of food and does not have a great impact on pulmonary nodules. Therefore, there is no clear contraindication of fruit for pulmonary nodules, and generally speaking, it is okay to eat fruit in moderation as long as it is not combined with other diseases. It should be noted that nodules in the lungs may be related to chronic pneumonia, tuberculosis pneumonia, lung tumors or lung cancer, and further tests are needed to clarify the cause and treat the related diseases for the cause. The effect of fruit consumption in these cases is minimal, and it is more important to quit smoking and alcohol, avoid exposure to harmful air, and be actively examined and cooperate with treatment or regular follow-up. In contrast, pulmonary nodular disease may interfere with calcium metabolism and increase the risk of kidney stones by elevating blood and urine calcium in the body, so regular checks of blood or urine calcium levels should be accompanied by control of vitamin D and calcium intake. The amount of vitamin D and calcium in fruits is limited, but nuts and deep-sea fish are rich in vitamin D. Dairy and soy products are rich in calcium, and the amount of consumption should be controlled according to the results of blood and urine calcium tests.
