Supermarkets on the shelves, the freezer, a wide variety of food is mouth-watering, but some food despite the attractive color, cooking convenience, too much food will have a negative impact on human health is invited to China Agricultural University Food Science And Associate Professor Zhu Yi, College of Nutritional Engineering.
White pasta. However, some businesses in order to increase the pasta white brightness, will add 'benzoyl peroxide' and other brighteners, the content even far more than the national permit, and some use of sulfur Fumigation, these two whitening methods will seriously damage the original vitamins, harmful to health, even if it is not whitening the white flour flour, refining process is to remove the grain cortex and grain embryo and dextrin layer, lost part of the nutrients, So the color of the more white nutritional value will be lower.
Fried food. Fried foods have more oil and oxides, high calorie, eat easily lead to obesity, hyperlipidemia and coronary heart disease.In addition, Zhu Yi said that with the frying time, the oil will produce trans fatty acids, As well as many carcinogenic substances, adverse human health.
Bulk nuts. Bulb nuts are relatively favorable, but nuts are rich in oil, if prolonged contact with air, easy to oxidize and degenerate, produce harmful substances, ranging from diarrhea, heavy damage to the liver. Bulk nuts shorter shelf life, it is recommended to give priority to buy seals Bagged, it is best to buy short-term will be able to eat a small package and pay attention to sealed in a dry and cool place.
Meat. Finished meat is very popular in the major supermarkets, not only removed from the processing of the family links, very convenient, but also cheaper than fresh meat.However, some of these meat is scrap or fineness of meat processing Into, and even worse also choose near the expired meat as raw materials, not only poor quality, but also easy to breed bacteria.
preserved fruit. The fruit is fresh and transparent, the surface is dry and slightly sticky. During the processing, the nutrients contained in the fruit will be lost, but add the fruit. A lot of sugar. Long-term intake of high-sugar foods will lead to the lack of vitamins and certain trace elements.In addition, many businesses in order to pursue the beauty and taste of preserved food, add more preservatives and food additives, regular consumption will affect health.
Cooked meat cooked simple and convenient cooking, color and flavor is superb, but in the cooking process by adding more oil, salt, soy sauce, monosodium glutamate and other condiments, and marinated nitrite and protein decomposition products will be synthesized Carcinogenic substances, increased colon cancer, breast cancer and other cancer risk. Bulk meat cooked food is also very easy to be pathogenic microbial contamination, causing diarrhea.
