If lung adenocarcinoma patients do not have high blood pressure, they can eat soy sauce, and eating soy sauce in moderation has no effect on lung adenocarcinoma patients. At present, there is no contraindication of “lung adenocarcinoma patients should not consume soy sauce” in the diagnostic and therapeutic program of lung adenocarcinoma in our country, but soy sauce is high in salt content, so the patients should pay attention to the principle of moderation in consuming soy sauce. If patients with lung adenocarcinoma also suffer from high blood pressure, they should pay attention to eating less soy sauce and low-salt diet. Because excessive intake of soy sauce can easily cause water and sodium retention, which will aggravate high blood pressure. Lung adenocarcinoma patients should keep a good mindset and actively cooperate with physicians for treatment. At the same time, they should actively buttress the physician and formulate a reasonable diet program according to their comprehensive situation.
