What beans should breast cancer patients avoid eating?

Introduction
Moldy soybeans produce aflatoxins, which are strongly carcinogenic and may worsen the condition or affect treatment outcomes. Consumption by breast cancer patients increases the body's burden and is不利于 (not conducive to) health recovery. Kidney beans contain saponins and lectins, which are not destroyed when undercooked. Consuming undercooked kidney beans may cause poisoning symptoms such as nausea and abdominal pain. Breast cancer patients generally have weakened physical conditions.

　　Under normal circumstances, the claim that breast cancer patients cannot eat beans is too absolute. However, certain specially processed beans, such as moldy soybeans, undercooked kidney beans, pickled broad beans, fried chickpeas, and tofu with added hormones, should be consumed with caution. Detailed explanations are as follows:

　　1. Moldy Soybeans: Moldy soybeans can produce aflatoxins, substances with strong carcinogenic properties that may worsen the condition or affect treatment effectiveness. Consumption by breast cancer patients increases the body's burden and is detrimental to recovery.

　　2. Undercooked Kidney Beans: Kidney beans contain saponin and lectin, which are not destroyed if undercooked. Consuming undercooked kidney beans may cause poisoning symptoms such as nausea, vomiting, abdominal pain, etc. Breast cancer patients, whose bodies are generally weaker, are more susceptible to harm.

　　3. Pickled Broad Beans: A large amount of salt is added during the pickling process, resulting in high salt content in the beans. Additionally, nitrites may be produced. Excessive consumption increases the kidney's workload, and nitrites pose health risks, both of which are unfavorable for the patient's physical recovery.

　　4. Fried Chickpeas: Chickpeas fried at high temperatures contain significant amounts of oil and trans fatty acids, and have high caloric content. Overconsumption may lead to obesity, which can affect hormone levels in breast cancer patients, negatively influencing disease recovery.

　　5. Tofu with Added Hormones: Some unscrupulous vendors may add hormones to increase tofu production. Such tofu can disrupt the body's endocrine balance. Since breast cancer is related to hormone levels, consuming this type of tofu may affect treatment outcomes and exacerbate fluctuations in the condition.

　　Breast cancer patients should prioritize fresh, natural, and light foods. When consuming beans, choose fresh varieties from reputable sources, ensure they are thoroughly cooked, and consume them in moderation. If discomfort occurs after consumption, consult a doctor promptly to adjust the dietary plan.
