Nutrients

Nutrients (nutrient) are chemical constituents that provide energy to the body, make up the body and tissue, and have a physiological regulatory function in food. All kinds of substances needed to maintain human health and provide growth, development and labor are called nutrients. The essential nutrients of the human body are proteins, lipids, sugars, vitamins, water and inorganic salts (minerals), dietary fiber (cellulose), 7, and many non-essential nutrients.

Fiber

Crude fiber is the main component of plant cell wall, including cellulose, hemicellulose, lignin and keratin and other components. Eating some of the food containing crude fiber can promote gastrointestinal motility, can help digestion to a certain extent, is beneficial, but the crude fiber can also hinder digestive enzymes in the alimentary canal contact with the food to reduce the digestibility of nutrients, in addition to the crude fiber can also hinder the intestinal absorption of some small molecular nutrient substances.

So the advantage of crude fiber is to help digestion, the disadvantage is to reduce the nutrient absorption rate.

Crude fiber food refers to every hundred grams of food containing more than 2 grams of crude fiber food, crude fiber can increase the volume of feces, reduce the intestinal residue in the body of the time to stay, so that the frequency of defecation, nutrition on the recommended intake of crude fiber per person per day 20~35 grams, eat more instead will reduce the utilization of other nutrients.

　　celery is a high-fiber food, celery contains more nutrients in the leaves , should be connected with the leaves to eat, do not eat only the stem to lose leaves.
