Salad is eaten in western food, both in Europe and America. There are many kinds of salads, but they are mainly fresh vegetables, with some salad dressing and some other sauces or condiments according to your own taste. It is a very healthy food because it contains less oil and salt. But personally, cooked food is better for the stomach, and the stomach likes warm food. Salad temperature is low, which is not good for the stomach, especially for people living in the south of China. It's ok to eat in the north, because it's hot in the north and cold in the south, so it's better to eat less.
