Dietary fiber is widely found in a variety of vegetables, among which those with high dietary fiber content include hairy peas, okra, fava beans, spring bamboo shoots and so on. Dietary fiber has an important nutritional value, i.e., it can increase the volume of feces and promote intestinal peristalsis, thus benefiting intestinal health. Healthy people need to consume an appropriate amount of dietary fiber to ensure that the volume of feces reaches 150-200 g/day. Dietary fiber is widely found in vegetables, with both high and low levels. Vegetables with high dietary fiber content include hairy bean, okra, broad bean, spring asparagus, and garlic moss. Each 100 grams of hairy bean contains 4 grams of dietary fiber, each 100 grams of okra contains 3.9 grams of dietary fiber, each 100 grams of fava bean contains 3.1 grams of dietary fiber, each 100 grams of spring asparagus contains 2.8 grams of dietary fiber, and each 100 grams of garlic moss contains 2.5 grams of dietary fiber etc.. The Dietary Pagoda stipulates that healthy adults need to consume 300-500 grams of vegetables every day to maintain the nutritional needs of the organism. One of the important reasons is that vegetables contain more dietary fiber, which is good for intestinal health.
