According to a survey released by the U.S. Institute of Occupational Safety and Health in 2007, some people may suffer from lung disease due to smoke from inhaling popcorn cooked in the microwave for a long period of time. The lung disease is related to the workers who work in the popcorn plant. Like lung disease, the main reason may be the use of Lutetium and other additives in the production of popcorn, causing bronchiolar disease.
In the process of making popcorn, additives may be used. The inhalation of additives can cause “obstructive bronchiolitis,†commonly known as “popcorn lungsâ€. The pathological basis of "obliterative bronchiolitis" is damage, inflammation, fibrosis, and luminal stenosis of the bronchioles. The common symptoms of the patient are fever, dry cough, wheezing, difficulty in breathing, aggravation after activity, accompanied by general discomfort, chills, and Weight loss; severe cases can cause respiratory failure or even death.
The respiratory system is in communication with the extracorporeal environment. Adults have more than 10,000 liters of gas entering and leaving the respiratory tract every day for gas exchange. Organic or inorganic dust particles in the external environment, including various pathogenic microorganisms, allergens, harmful gases, etc., may enter the respiratory tract during the respiratory process. Smoking, car exhaust, air pollution, etc. cause PM10 (inhalable particulates), PM2.5 (into the lung particulates) exceed the standard; occupational exposure to inhalation of silica, coal dust, cotton dust and other dust or industrial exhaust and other factors will lead to chronic obstruction Lung disease, pneumoconiosis, lung cancer and other respiratory diseases; the widespread use of carpets, cloth curtains to increase the number of indoor dust mites; cats, birds, dogs and other pets cause increased skin animal allergens; air-conditioning machine breeding fungus, flowers and plants Pollen spores, etc., lead to an increased incidence of bronchial asthma and allergic rhinitis.
Xinhua News Reporter: What are the harmful substances that popcorn we eat daily?
Qu Yanqiang: According to my understanding, we will add some sweeteners and flavors to the popcorn that we eat daily, and some trans-fatty acids (also known as botanical cream, margarine, and hydrogenated vegetable oil) will be added to increase the crispness. The fat-processed foods are crisp and crunchy. The common crisp breads, biscuits, instant noodles, and cream cakes contain some trans-fatty acids. Trans fatty acids are harmful to the human body after intake. For adolescents, trans fatty acids can affect essential fatty acid absorption, resulting in poor development of the central nervous system. For adults, it may cause problems such as infertility, obesity, cardiovascular and cerebrovascular diseases, Alzheimer's disease, and diabetes.
In the process of processing corn into popcorn, water loss and nutrient loss were as follows: 100 g of carotene in 100 g corn kernel was 100 g, while 100 g of popcorn carotenoid was 0; calcium 49 mg/100 g and popcorn 2 mg. /100g. In the same 100 grams of popcorn, the amount of carbohydrates and the fat content increase compared with 100 grams of corn.
Xinhua News reporter: What advice do you have for users of popcorn?
Zhang Yongming: Do not eat too much popcorn. If you use popcorn heated in a microwave oven, keep it away from the heating area. Open the bag after heating and distribute it on a ventilated area. The “converter†popcorn on the street contains lead in the “converterâ€. When heated at high pressure, a certain amount of lead in the pot will melt and be absorbed on loose rice. After consumption, chronic lead poisoning may occur, which may harm nerves, hematopoiesis, and digestion. Other systems affect children's development.
Some small traders will use vegetable butter made from hydrogenated vegetable oil instead of butter when making popcorn. The trans-fatty acids contained will increase blood cholesterol levels and increase the risk of coronary heart disease.
