Eating too much fried food is harmful to health, such as obesity, indigestion, cardiovascular injury, respiratory injury and even cancer. In addition, the high temperature during frying will destroy the nutritional components of ingredients, such as vitamin C, vitamin B2, nicotinic acid and essential fatty acids, resulting in the nutritional value may be lower than the original 1/3.

1, Obesity: Fried food is a high-fat and high-calorie food, and the accumulation of heat in human body will lead to obesity;

2, indigestion: after the food is fried, the surface is covered with a lot of oil, which can increase the digestive burden of the gastrointestinal tract and cause indigestion symptoms such as bloating and diarrhea;

3, cardiovascular damage: eating fried food for a long time is easy to cause hyperlipidemia, and the risk of atherosclerosis in the body increases. If the blood supply artery of the heart is blocked by viscous blood, coronary heart disease can be induced;

4, respiratory system damage: the oil fume in fried food will stimulate the human nasal cavity and throat mucosa, and long-term large-scale consumption can induce rhinitis, pharyngitis, bronchitis and other diseases;
