Fried potatoes are rich in hazards:

1, carcinogenic. Containing starch (potatoes and other) food fried will produce carcinogens acrylamide, fried fast food also contains promote aging "late glycosylation end products";

2, easy to eat fat. The practice of deep-frying is more likely to increase the energy of potatoes. In the process of frying, the energy of potatoes will increase in 92% -148%, easy to eat fat, to not grow meat usually to eat less;

3, nutritional decline. And potatoes in the deep-frying process, vitamin C will also be destroyed, but the potato skin can play a protective role, to a certain extent, can avoid this process of nutritional loss.

It is recommended to reduce the frequency and quantity of eating fried fast food. If you especially want to eat, try to remove the crispy skin on the outside after frying, and with fresh vegetables and fruits, the dietary fiber and vitamins in them can help reduce the harm caused by deep-fried fast food.

Expanded:

Acrylamide, which is produced in fried potatoes, is unintentionally formed as a result of heating during food processing and is a chemical contained in food. The International Social Risk Assessment Agency (ISRA) has concluded that acrylamide-containing foods may cause adverse health effects if consumed over a long period of time.

When making fried potatoes, the frying time should also not be too long, not to fry more than one at a time, and most importantly, not to fry the batter, the more burnt the more likely to produce acrylamide. Long-term low-temperature storage of potatoes is best boiled or steamed.

The Nihon Keizai Shimbun points out that in the process of deep-frying food, not only will acrylamide be produced, but also some beneficial substances that prevent acidification of the body, such as appetite-inducing flavors. Therefore, if acrylamide is overly suppressed, it may also reduce the production of effective substances and even impair the flavor of the food, so it is most important to have a balanced nutritional profile, aiming for something that is both healthy and safe as well as tasty.
