Cow's milk, fish, eggs, wheat, beans and legumes are some common offenders. Food additives, like preservatives and food dyes, may also be culprits in an allergy-induced attack. Eliminate problematic foods from your child's diet. Cow's milk, milk products, starches, sugars and eggs tend to increase mucous secretions. Be sure your child drinks normal amounts of clear fluids in order to reduce the thickness of secretions.
Liquids are best at room temperature or warm since cold drinks tend to cause coughing.
Bromelain, which is found in fresh pineapple, may help to liquefy secretions. Vitamin B 5 supports adrenal gland functioning. The adrenal gland produces cortisol and epinephrine which assist in dilating the bronchioles. Vitamin C also supports adrenal gland function and has antihistamine properties. Supplementation with magnesium may be recommended for its bronchodilating effect.
