Not eating fruits for a long time may lead to insufficient intake of dietary fiber, carbohydrates, vitamins and other nutrients. Fruit is an important category in the dietary pagoda, including many food types, providing the body with a variety of nutrients, such as carbohydrates, fats, proteins, vitamins, minerals, water, as well as a relatively rich dietary fiber. If fruit is not consumed for a long period of time and cannot be replaced by other foods, it may lead to a deficiency of the above nutrients, which is not conducive to human health. Therefore, the dietary guidelines recommend that adults consume about 200 to 350 grams of fruit per day to meet the body’s nutritional needs, not picky eaters, and at the same time should be combined with meat, staple foods, vegetables, eggs and milk and other foods, to maintain a balanced nutritional intake.
