High fiber is a type of food that is beneficial for health. It is found in many fruits, vegetables, legumes, and grains. NAP is an acronym for Non-starch polysaccharides, which are complex carbohydrates that are high in fiber. These carbohydrates are not easily digested by the body, but they provide essential nutrients and help to regulate digestion. Eating foods high in fiber can help to reduce cholesterol levels, improve digestive health, and promote weight loss.
