Healthy dishes should be processed scientifically and reasonably on the basis of ensuring food safety, so as to achieve the process of human tissue renewal and material metabolism. First, the materials should be safe and fresh, and then processed reasonably. The premise of reasonable processing is reasonable cooking. The size of processed raw materials will lead to the loss of nutrients in food, and the number of cleaning will also lead to the loss of high nutrients. Water-soluble nutrition loses more and fat loses less; In cooking, unscientific cooking methods, such as baking and smoking. However, frying experts point out that scientific cooking of healthy dishes does not mean that it has nothing to do with delicious food. No matter what kind of food, as long as it is food, it must be delicious. For example, spicy food is not necessarily bad food. Spicy food can speed up blood circulation, dispel dampness and clear heat, but it should be suitable for different regions and vary from time to time. Nowadays, popular health care dishes also pursue diversified tastes, including medicated diet. Medicinal diet is not necessarily a combination of vegetables and medicinal diet. Chefs have a purpose, choose collocation, people choose to eat, and eat scientifically and nutritionally. For example, lily and celery together can clear away heat, reduce blood fat and increase lung vitality. In addition, many people think that it is unhealthy to blow things up with an electric bomb. In fact, frying does not necessarily increase oil. For example, the chicken leg of an old chicken has a lot of oil under its skin. If you add some more things and fry them with a coal-fired frying machine, you can fry all the oil. When braised pork is oiled, a lot of fat can come out. Frying in oil is not the same as stewing in water directly. Stir-fry a lot of oil first, so that you can skim off the oil and not eat it. If stewed directly, protein will go bad and be insoluble in water. This kind of meat is very fat.
