Salmon is one of the foods rich in polyunsaturated fatty acids omega 3.
The omega 3 fatty acids contained in fish oil have the ability to decrease the production of IgE, the antibody involved in allergic reactions and asthma in people with mild asthma symptoms. In the most severe cases of asthma, however, the use of oral steroids to alleviate the disease interferes with the benefits of omega-3, reducing its effectiveness.
In patients with asthma taking corticosteroids by mouth, the fatty acids omega 3 were less effective
These are the conclusions of a study conducted by researchers from the Center doctor of the University of Rochester (UR) in New York (United States), involving 17 patients with asthma. The researchers isolated B-cell immune from these people and compared them with the of healthy donors, with the aim of analyzing the impact that have fatty acids from the fish oil on IgE and other molecules involved in the disease.
Most of the patients in the study took different doses of corticosteroids by mouth – pill or using an inhaler – depending on the severity of asthma, and although all responded to some extent to the fatty acids omega 3 and there was a decrease in the levels of IgE antibodies, scientists found that some patients taking oral steroids worse responded to treatment with omega-3.
Richard P. Phipps, Professor of environmental medicine, and lead author of the work, explained that consumers must ensure that fish oil that is of good quality, since they used pure and biologically active products of fish oil, are called 17-HDHA, similar to that used in a previous study, published in the New England Journal of Medicine that showed that administration of supplements of fatty acids omega 3 during pregnancy reduced the risk of the baby developing asthma.
The expert added that the consumption of polyunsaturated fatty acids omega 3 – which can be found in foods such as salmon, tuna, flax seeds, nuts or anchovies-oil has proven to be beneficial to health, since they become special mediators hindering inflammation without suppressing the immune system in the body.
