Introduction
Under normal circumstances, "four-season beans" refer to common beans (Phaseolus vulgaris). It is not recommended to eat common beans that are slightly undercooked. These beans contain natural toxins such as saponins and phytohaemagglutinin, which may not be fully broken down when the beans are undercooked. Consuming them in this state may cause symptoms such as nausea, vomiting, abdominal pain, and diarrhea, and could even lead to food poisoning, resulting in discomfort including headache, dizziness, and fever.
Under normal circumstances, "four-season beans" refer to kidney beans. Slightly undercooked kidney beans are not recommended for consumption. The detailed explanation is as follows:
Kidney beans contain natural toxins such as saponins and phytohaemagglutinin. These toxins are not completely broken down when the beans are undercooked. Consuming them may lead to symptoms such as nausea, vomiting, abdominal pain, and diarrhea, and could even cause food poisoning with discomforts including headache, dizziness, and fever. Moreover, phytohaemagglutinin has the ability to agglutinate and dissolve red blood cells, and long-term ingestion may pose health risks. Therefore, it is not advisable to eat kidney beans that are even slightly undercooked.
When cooking kidney beans, ensure they are thoroughly cooked. You can determine doneness by observing color changes, pressing the beans, or checking their texture. This helps guarantee food safety. Additionally, blanching the beans before cooking can help remove some of the toxins and unpleasant odors. Adding appropriate seasonings such as ginger slices and garlic may also enhance the flavor of the dish.
