Vegetables and fruits are important foods in people's daily lives, with vegetables playing a particularly crucial role in the diet. The various vitamins, dietary fiber, and inorganic salts required by the human body are mainly sourced from vegetables. Vitamins are vital substances for maintaining the normal functions of the body's tissues and cells, inorganic salts play an important role in maintaining the body's acid-base balance, and although dietary fiber cannot be absorbed by the human body, it can promote intestinal peristalsis and facilitate the excretion of feces.
Fruits are also indispensable foods for the human body. Fruits contain some essential nutrients for the body and are also convenient to eat raw. Some people, especially urban office workers, mistakenly believe that eating fruit can replace eating vegetables, but this understanding is incorrect:
On one hand, only fresh fruits are rich in vitamins, but the fruits we usually eat are mostly stored for long periods, resulting in significant loss of vitamins, especially vitamin C.
On the other hand, no single food can meet the diverse needs of the human body. Only by consuming a variety of foods simultaneously can one obtain all the necessary nutrients. Therefore, it is necessary to eat both fruits and vegetables. Vegetables are abundant in variety, widely available, and inexpensive. By choosing different vegetables for the three meals a day, one can obtain all the nutrients the body needs.
