Omega-3 fatty acids against symptoms of Asthma?
It is already known for some years that the increase in air pollution will affect the likelihood of the emergence of Asthma and the Severity of the disease. New results show that the diet can play an important role in the pathogenesis of Asthma. Omega-3 fatty acids seem to reduce Asthma symptoms.
In a recent study by the Johns Hopkins University, it was found that air pollution out of the symptoms of Asthma triggered by the increased consumption of Omega-3 fatty acids may be reduced. The results of the study were published in the English journal “the American Journal of Respiratory and Critical Care Medicine”.
Omega-3 fatty acids reduce the Asthma symptoms
The new study has shown that a higher consumption of Omega-3 fatty acids, found in oily fish such as salmon and sardines and in some plant sources such as walnuts and linseed, is associated with reduced Asthma symptoms in urban children. Asthma is an inflammatory respiratory disease-related. When the body digests fish, the Omega-3 fatty acids in addition to product molecules, so-called Pro-Resolution mediators, and reach the lungs. There you help in the elimination of inflammation, explained the research team. In the face of this anti-inflammatory effect, they had the presumption that a diet, which is rich in Omega-3 fatty acids, can mitigate the impact of air pollution on Asthma symptoms of children.
135 children participated in the study
In the study, the diet and air pollution in the indoor environment (from sources such as smoke, dust, and allergens) in the homes of 135 children with Asthma in Baltimore analyzed. The researchers two types of measured indoor air pollution, which consist of various particle sizes: PM2. 5 (fine,respirable particles that are 2.5 microns or smaller) and the larger PM10. A higher intake of Omega-3 fatty acids was a reduction in the effect of particles in the inside of the symptoms. Children who consumed more Omega-3 fatty acids, appeared to be more resistant to the effects of the particles.
What is the role of Omega-6 fatty acids play?
The researchers studied the intake of Omega-6 fatty acids, which are found in vegetable oils and many processed foods, which contain Oil, are abundant. The study found that children who had the most Omega-6 fatty acids consumed, increased Asthma symptoms. The role of Omega-6 fatty acids in inflammation is complex. It has been shown that some are by-products of Omega-6 acids (for example, leukotrienes) proinflammatorisch. Leukotrienes are one of the molecules of which it is known that they are for inflammation in Asthma are responsible, explain the authors of the study.
Omega-3 fatty acids protect the heart
Since this is an observational study can’t prove the researchers clearly state that the Omega-3 acids have led to a decrease in the symptoms or that the high intake of Omega-6-caused by acids, more serious symptoms. The results fit to a variety of Evidence documenting the anti-inflammatory effects of Omega-3 fatty acids. This study adds to a growing literature suggesting that the diet can influence the health effects of air pollution. In a recently in the English journal “Circulation” has published a study, for example, found that a Mediterranean diet the risk of cardiovascular disease is reduced in connection with a long-term exposure to air pollutants.
