Both animal oil and vegetable oil have their advantages and disadvantages, and it is impossible to simply say which is healthier. Animal oils are mainly saturated fatty acids, such as butter and lard, which are stable at high temperature and suitable for cooking and frying food. However, excessive intake of saturated fatty acids may increase the risk of heart disease and hypertension.

Vegetable oils are mainly unsaturated fatty acids, such as olive oil and linseed oil, which help to lower cholesterol levels and protect heart health. Vegetable oil is also rich in vitamins and antioxidants, which helps to improve immunity and prevent chronic diseases.

Therefore, choosing the right oil depends on personal health and eating habits. It is suggested that vegetable oil, such as olive oil and rapeseed oil, and a small amount of animal oil, such as fish oil and sunflower oil, should be taken in the diet in order to obtain a balanced fat intake.
