Under the condition that the potatoes are not sprouted and the eggs are not spoiled, scrambled eggs with potatoes are generally not poisonous and can be eaten without worry. If you experience breathing difficulties and skin rashes after eating scrambled eggs with potatoes, it may be related to an allergy to the ingredients and is not caused by a toxic reaction. Some people believe that oxalic acid in potatoes can react with calcium in eggs to produce calcium oxalate, which is not absorbed by the body and is therefore easily deposited to the detriment of human health. However, considering that the content of the elements in food are small, in the case of normal consumption, it is not enough to harm the human body or cause a toxic reaction. Therefore, in general, you can choose fresh potatoes and eggs cooked for consumption without any significant adverse reactions. If the potatoes have grown new shoots, or the eggs have developed a bad taste or changed in texture or color, cooking both will cause food poisoning due to toxic and harmful substances present in the food, such as lobotropin. In addition, a small number of people are allergic to potatoes and eggs, and those who have experienced itching, redness, pimples, diarrhea and other allergic reactions after eating potatoes and scrambled eggs in the past may also be triggered by allergic reactions again, and need to seek medical treatment with drugs in a timely manner. Therefore, we should pay attention to the freshness and health of ingredients to ensure our health. At the same time, it is necessary to identify your own allergens and avoid contact with them in order to reduce the risk of allergic reactions.
