Vitamin C and Omega-3 fatty acids may help teens fight asthma

Omega 3Definition:

Vitamin C – An essential water soluble vitamin which presents broad variety of purposes in the human body and the most significant purposes of this vitamin is to act as antioxidant and LDL (Low-Density Lipoprotein) cholesterol from oxidative damage.

Omega-3 [Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA)]– It’s a family of unsaturated fatty acids derived from linolenic acid which the most important sources of fish oil and vegetables such as flax seeds, hemp seeds, walnuts, and canola oil. The most well known was Omega 3 fatty acids that found in fish oil and was clinically proven on numerous health benefits for human life.

Fatty Acids – Its Individual isomers which commonly known as, FATS which has different potential hundreds of fatty acids and only few dozen of the hundreds found in the food we eat.

Asthma – Is the chronic condition that involve in the respiratory system which the airways sometimes become inflamed, constrict, and are lined with excessive amounts of “mucus” often in response to one or more triggers.

Base on the study held and which published in the Journal Chest – The intake of Vitamin C and Omega 3 essential fatty acids may help “to promote respiratory health and lessen the effects of oxidative stress” for the teenagers who had ASTHMA.

According to author Jane Burns of the Harvard School of Public Health in Boston: “Teens that have the lowest intake of fruits, vitamin C and omega-3 fatty acids tended to have lower pulmonary function and reported more respiratory symptoms than those with higher intake.”

The researchers said “examined the association of dietary factors (fruit, vegetables, vitamins C and E, beta-carotene, retinol, and omega-3 fatty acids) with respiratory health in a cohort of 2,112 12th grade students in 13 communities in the United States and Canada.” As the study going on, they do some question on the teens about their diets, general health, and respiratory symptoms then it tested their adolescents’ lung function as well.

Majority of the teenagers were white, about one-third were overweight and almost three-quarters didn’t take a daily multivitamin. About one-third of the teenagers had dietary decrease when it comes to consumption of fruits, vegetables, vitamins A and E, beta-carotene, and omega-3 fatty acids. A high of 86% didn’t consume the recommended serving of fruits and vegetables each day which should be five to nine servings.

The researchers furthermore discovered that consumption of less than one-quarter of a serving of fruit daily resulted in lower average lung-function scores. A low intake of vitamin E—less than 5.2 mg daily—was associated with an increased risk of reported asthma. A low intake of omega-3 fatty acids—less than 22 mg per day—was associated with increased odds of chronic bronchitis, wheezing and asthma. As a matter of fact based, those with lowest intake of omega 3 fatty acids are those more likely reported for asthma symptoms which are 70%.

Additional data, based on the researched teenagers is urged to increase their intake of all natural vitamins and omega 3 fatty acids.
