What are the tips for buying green beans?

The pods are full, plump and juicy, with no old tendons when broken, tender green in color, and smooth skin without insect marks. In addition, there are many varieties of green beans, and the quality of different varieties varies greatly. Generally, the quality of long pods (tall stalks) is better than that of short pods (short stalks), and the round stick pod type is better than the flat pod type. But there are exceptions, such as the tall stalks, flat pods, and white shells produced in the Northeast, commonly known as oil beans, which are tender, glutinous and delicious. Regardless of the type, brown spots, commonly known as rust spots, are prone to appear on the skin during storage, indicating that it has aged, the skin turns yellow, the degree of fibrosis is high, the pods are dehydrated, and the quality has deteriorated. When purchasing, you should choose green beans with bright green color and firm pods. When breaking this kind of green beans, you can see that the pod wall is full in the cross section, there is no gap between the beans and the pod wall, and there are few tendons on both sides.

Are underripe green beans poisonous?

Although green beans are a very nutritious food, it is true as others have said that eating uncooked green beans can cause poisoning. Green beans contain saponins, the toxic components of which are mainly saponins and trypsin inhibitors. These saponins are very irritating to the gastric mucosa and can easily cause congestion in certain parts of the stomach and intestines. The saponins in green beans can also destroy red blood cells in the human body. Once poisoned, people may experience abdominal pain, diarrhea, nausea and vomiting, and in severe cases, numbness of the limbs. High temperatures can destroy the toxicity of green beans, so green beans must be thoroughly cooked before eating.

If you have mild poisoning from green beans, you can drink some strong tea or sugar water, and then rest more. If you feel anxious, you can take some sedatives in moderation. I heard that there is a folk remedy that can cure green bean poisoning, which is to boil licorice and mung beans and drink the water. The detoxification effect is good. If the symptoms of poisoning are very serious, it is best to go to the hospital for treatment. Generally, green bean poisoning will heal in one or two days.

What should you pay attention to when eating green beans?

1. Don't eat green beans raw. Green beans contain toxic substances and eating them raw can cause poisoning, so you must cook them before eating them. If you think green beans are not easy to cook, you can soak them first, or blanch them in boiling water before frying.

2. Be careful to control the amount when eating green beans. Green beans can make you feel full after eating, so be careful to control the amount when eating green beans. Don't eat too much, otherwise you may suffer from indigestion.
