The old adage “you are what you eat” is particularly true for teens with respiratory problems. According to a recent study by U.S. and Canadian researchers, teens who don’t get enough antioxidants and anti-inflammatory nutrients in their diet have more respiratory problems than teens who eat meals that do provide these essential nutrients. The poorer the diet, the greater the risk of cough, respiratory infections, bronchitis, wheezing, and more severe asthma-related symptoms–especially in teens who smoke. The study authors reported that teens who have low dietary intakes of fruit, vitamins E and C, and omega-3 fatty acids are at greater risk of developing asthma. How can busy parents ensure that on-the-go teens eat right? For starters, make sure your teenager takes a daily multivitamin supplement with breakfast, pack fresh fruit in your child's backpack, and prepare simple but balanced family meals.
