Deep-fried food is high in calories, high in oil and oxidants. Eating too much can easily lead to obesity, and at the same time, a large number of carcinogens are often produced during frying.

Food fried at high temperature will destroy many nutrients, including vitamin A, vitamin D and vitamin E; The destruction of essential fatty acids will also affect the absorption and utilization of vitamin B 1
Extended data:
Energy density: Also called heat density. Refers to how much energy (heat) is contained in a unit weight or volume of food. Because water and dietary fiber do not contain calories, foods with high water content and fiber content have low energy density, such as vegetables and fruits.
Because the calorie of fat is the largest of the three energy-supplying nutrients by weight, the more fat there is, the higher the calorie is among the foods with the same moisture content. The food with low moisture, dry goods and high fat content has the highest calorie value. Such food, if the nutrient content is low, is very unfavorable to prevent obesity. For example, biscuits, cookies and potato chips are not worth eating often.
Give priority to those foods with large water content, less dry goods and less "oil and water" among similar foods, even if they are eaten in a larger size, there is no need to worry about getting fat. To be exact, if you eat more of this kind of food, other high-calorie foods often lose your appetite and are not easy to get fat. This is the so-called "eat more and gain less weight".
