What should teenagers pay attention to in their diet when their voice changes?

　　The quality of your voice is determined by your vocal cords. The vocal cords are a pair of elastic mucosal folds located on both sides of the laryngeal cavity. Their length and thickness vary from person to person. In childhood, the length of the vocal cords for both men and women is 6 mm to 8 mm, so the sounds produced are childish sounds. When teenagers are 14 to 16 years old, they begin to enter the voice change stage, which is mainly characterized by hoarseness, local congestion, edema, and gradual changes in pitch and timbre. It usually takes half a year to a year to complete the voice changing period. The voice of an adult man is rough and deep, with a wide and thick volume, which is closely related to the thickness, width and length of his vocal cords (about 20 to 25 mm). Adult women have a high-pitched voice, which is related to the narrowness, thinness and length of the vocal cords (15 to 20 mm). It can be seen that the difference between male and female timbres is particularly obvious after voice change. In order to ensure that girls have a good voice during the voice-changing period, dietary conditioning should be emphasized.

　　(1) When eating, you should chew carefully and slowly and avoid gobbling. Especially those who eat fish should be careful to prevent fish from stabbing their throats. You should also eat soft foods and fine foods. It is not advisable to eat coarse, hard, dry and other foods to prevent damage to the throat.

　　(2) Drinking an appropriate amount of water can reduce or clear the secretions in the throat cavity. To prevent the occurrence of pharyngitis. In addition, do not shout loudly during the voice change period, do not be overtired or sleep deprived, and do not cause mood swings to prevent vocal cord damage due to throat congestion.

　　(3) Eat less or no spicy food. Such as chili, garlic, pepper, tobacco and alcohol, to prevent irritation of the vocal cord mucosa and cause acute and chronic laryngitis and pharyngitis.

　　(4) Pay attention to the intake of collagen and elastin. Because the vocal organs are mainly composed of the larynx, Adam's apple, and thyroid cartilage, these organs are composed of collagen and elastin. Vocal cords are also made of elastic protein films. For this reason, teenagers in the voice-changing period should eat foods rich in collagen and elastic proteins, such as pig's trotters, pigskin, tendons, etc.

　　(5) Vitamin B and calcium should be taken in. Vitamin B2 and D6 can promote skin The development of the brain is also conducive to the development of the vocal cords. Calcium promotes the development of thyroid cartilage.
