Can a fruit a day keep asthma away?
A new study shows that a low dietary intake of certain nutrients increases the likelihood of respiratory symptoms such as asthma, especially in teens who smoke. A lack of these nutrients may also lead to lung function.The research, suggests that higher intakes of antioxidant and anti-inflammatory micronutrients are associated with lower reports of cough, respiratory infections and less severe asthma-related symptoms. Teenagers who have low dietary intakes of fruits, vitamin E and omega-3 fatty acids are at greater risk of having this sickness. The researchers examined the association of low dietary nutrient intake with low pulmonary function and respiratory problems.
During late adolescence, physical stature has been attained and lung growth closely parallels this growth. Therefore they were observing a time when lung function was close to its optimal capacity. They also said that although their diet surveyed targeted only the eating habits for the past year, it did give them some idea of the teens general past diet. However, their current respiratory health may be a reflection of diet during childhood, as well as during past years.
Vitamin supplements can help teens meet their daily recommended levels and surprisingly, even relatively low levels of omega-3 fatty acids appeared to protect teens from higher reported respiratory symptoms.
Results showed that low dietary intakes of fruits, vitamin C and E, and omega-3 acids were associated with decreased lung function and a greater risk of chronic bronchitis symptoms, wheeze and asthma. These risks were further increased among students with the lowest intakes and who also smoked.
Researchers are hoping that a fruit a day will keep asthma away, but it is a complex disease with genetic component. However, it may be that certain foods can lessen or prevent this symptom. The most important thing to remember is that diet can have a significant impact on teens’ respiratory health. We would encourage them to make healthy eating as part of their daily routine, and stress to them that smoking is bad. It emphasized that fresh fruits make for convenient snacks. They also suggest in preparing simple, daily family meal, as a method to promote both communication and good nutrition.
Balanced diet is good not only for lung health, but for general health. Parents and physicians should work together to monitor and maintain healthy diets and lifestyles for children of all ages.
