Compared with China's diet which pays attention to "taste", the west is a rational concept of diet. Regardless of the color, fragrance, taste and shape of food, nutrition must be guaranteed, and how many calories, vitamins and protein should be taken in a day. Even if it tastes the same, you must eat it-it is nutritious. This concept of diet is compatible with the whole western philosophy system. Metaphysics is the main feature of western philosophy. The research object of western philosophy is the cause of things, and the cause of things is often metaphysical. The two are interrelated and form metaphysical philosophy. This philosophy has brought vitality to western culture and made it develop by leaps and bounds in natural science, psychology and methodology. But in other aspects, this philosophical proposition has been greatly hindered, such as food culture. At the banquet, you can pay attention to the collocation of tableware, materials, services and raw materials in shape and color. But no matter how luxurious and upscale steak is from L.A. to new york, it has only one flavor, and there is no art at all. As a dish, chicken is chicken and steak is steak. Even if there is a match, it is done in the disk. A plate of "French lamb chops" with mashed potatoes, leaning against the lamb chops, and boiled green beans and some tomatoes on the other side. The colors are in sharp contrast, but the raw materials are irrelevant, the taste is harmonious, each has its own flavor, and it is simple and clear.
