Answer:

Fried, fried, fried, baked, or in other words dishes that use grease at high temperatures, usually give us a very stimulating feeling of taste and appetite.

However, foods that have been fried, fried, fried at very high temperatures will contain trans fats – fats that have no nutritional value.

Not to mention, the foods for frying are also processed in vegetable oil or seed oil, available with trans fats before being reheated such as fried chicken, fried sausage, fried corn, french fries, fried spring rolls …

If it continues to be heated to a high temperature, the trans fat content of that dish will increase very sharply, which is the cause of cardiovascular pathologies (hypertension, fatty blood, fatty liver, atherosclerosis, myocardial infarction)… and especially rectal, pancreatic cancer…

In addition, high temperatures will break down the nutritional components in the grease.
