Taste preference: Modern people's tastes are more and more inclined to greasy food, because these foods usually have strong taste and mouthfeel, which can meet people's sensory needs for food. In addition, greasy food is more likely to make people feel full, because it requires more energy to digest.

Cooking method: In order to improve the taste and color of dishes, many restaurants often use a large number of high-fat ingredients such as oil, butter and cheese, which can enrich the dishes, but at the same time increase the greasy feeling.

Choice of ingredients: Some restaurants may choose to use cheap and high-fat ingredients, which usually taste better, but also increase the greasy feeling.

Nutrition collocation: Some restaurants may pay more attention to the taste and appearance of dishes, but ignore the nutrition collocation. If there are too many high-fat ingredients and staple foods in the dishes, but lack of nutrients such as vegetables and fruits, the dishes will be too greasy.

In order to keep healthy, it is suggested to control the intake of greasy food in restaurants, choose light and healthy dishes and side dishes, and increase the intake of nutritious foods such as vegetables and fruits. In addition, proper exercise and a balanced diet are also important factors to keep healthy.
