Mung bean porridge refers to porridge made from a mixture of mung beans and rice as the main ingredients. Mung bean is a common cereal. It is cold in nature and sweet in taste. It has the effects of clearing away heat and detoxifying, reducing fire and relieving heat. It is very suitable for consumption in summer. Mung beans are also rich in protein, vitamins and trace elements. They have very high nutritional value and are a very healthy natural food. Although mung bean porridge has many effects, it is not suitable for the following four types of people: People with cold constitutions (such as cold and weak limbs, cold and painful waist and legs, diarrhea and loose stools). These people have no heat in the body, but eating mung beans will make it worse. Symptoms such as cold limbs can even lead to other diseases. For the elderly, children and other people with weak constitutions, mung beans contain extremely high protein, which is equivalent to that of chicken and three times that of japonica rice. Mung beans contain macromolecular proteins, which need to be converted into small molecule peptides and amino acids under the action of enzymes before they can be absorbed by the body. The gastrointestinal digestive function of the elderly and children is relatively poor, and it is difficult to digest the protein in mung beans in a short period of time, and it is easy to cause diarrhea due to indigestion. People who are taking medicine: Since mung beans have detoxification effects, if the medicines you take contain ingredients such as organophosphorus, calcium, potassium, etc., mung beans will combine with these ingredients to form precipitates, thereby decomposing the efficacy of the medicine and affecting the treatment. Especially people who are taking some warming and tonic Chinese medicine should not eat mung beans to avoid reducing the efficacy of the medicine. However, some traditional Chinese medicines for clearing heat and purging fire, such as Coptis chinensis, Scutellaria baicalensis, Phellodendron cypress, Daqingye, Isatis root, bezoar, honeysuckle, etc., can complement each other and achieve twice the result with half the effort when taken with mung bean soup (porridge) or mung bean cake. Menstruating women’s bodies are in a state of blood loss and their constitutions are abnormal. If they eat cold food, it is easy to damage the spleen and stomach. Many people like to put the prepared mung bean soup in the refrigerator and take it out when drinking. It will taste cool. In fact, mung bean soup should not be drunk iced, otherwise it will cause spleen and stomach imbalance and diarrhea. People with weak spleen and stomach do not necessarily choose to drink mung bean soup, but can choose to eat mung bean porridge. The method of making mung bean porridge is as follows: put rice or millet and mung beans into a pot at the same time and add water to cook into porridge. Rice and millet have a nourishing effect on the spleen and stomach.
