Omega-3 fatty acids are associated with fewer childhood signs of childhood


Dundee children have a six-month study by Johns Hopkins Medicine suggesting that the diet of omega-3 acidity in the diet has resulted in fewer symptoms going on as a result of pollution. T interior. The same study concludes that the difference in sulfur amounts of omega-6 bites of omega-6 bats and their distribution may be linked to asthma worse.

The researchers present the results of the survey, published online in March 29 American Journal of Respite Care and Analytical Medicine, which suggests that families and health care providers can protect children from harmful effects of air pollution by eating more foods of omega-3 fatty acids, such as salmon, and reducing acidic foods. t geese omega-6, such as soy oil and oat oil. Ultimately, changes in school food may help make that diet in a diet.

"Our group is working on ways to reduce levels of indoor air pollution in homes in Baltimore Town," said Emily Brigham, MD, MHS, lead study author and assistant professor at Johnstown University School of Medicine. Hopkins. "The results are promising, but we don't want to stop there."

Internal air pollution, from sources include cooking, cleaning (ie, brushing) and cigarette smoke, is the inspiration for asthma symptoms. Earlier work by the research group showed that levels of internal air pollution, particularly items in the atmosphere in homes in the Baltimore Town, are often higher than appropriate standards for outdoor quality as set by the Defense Organization. US environment.

Brigham says that there is strong evidence that diet, in particular the levels of omega-3 and omega-6, are able to take part in lungs health by changing the body's response and response. Swelling of infections. The Omega-3 fatty acids, abundantly found in fish, and some nuts and seeds, are considered part of the reason they are decreasing. Omega-6 fatty acids, which are most commonly found in vegetable oil (including corn, cow, saffer and sunflower), have been surveyed in other studies for mixed health effects, but t Their ability to encourage inflammation. As children with asthma are now vulnerable to blows and breathing symptoms, the researchers thought that intakes of omega-3 and omega-6 could be linked to the asthma of the asthma, and as a result of Children responded to the air pollution in their homes.

The new survey included 135 children with asthma, ages 5 to 12. 90% of children were African-American, and 47% were girls. About one-third of pupils were of middle, third, and third sac. Researchers explained the seriousness of the sack and are based on guidelines for a National Program for Education and Time Out, which includes symptoms, respiratory practice and how well # 39; If the heavens breathe out. In general, the more symptoms, the more medicine you use, and the worse off lung work, the worse they have to think about. Participants and attendees reported a diet, asthma symptoms (recorded daily) and analysts' use in surveys for a week each week at registration, and again at three and six. T months. Researchers also collected blood examples to evaluate changes in reactive indicators each time a partner completed the surveys.

Each week the participants' household equipment measured two sizes of air pollution: a size with a diameter of 10 micrometers and less (one-six feet wide or less) and clips with a diameter of 2.5 micrometers and less. When they breathe, the larger parts are usually stored on the airplanes, but the smaller pieces can break in into the lungs reaching the heels t very small. Both areas of size have been visually obtrusive, linked to asthma symptoms in children and adults. The average rate for smaller populations in children's homes is 26.8 micrograms per cubic meter (the average EPA level for airborne is 12 micrograms per cubic meter), and the mean for the area taking into larger ones, 39 micrograms per cubic meter.

The children's survey of all extra omega-6 intakes, found that children on 29 per cent higher would be in a poorer condition of monuments. Each other gram of omega-6 in the diet was associated with a 2 per cent increase in daytime differences due to an increase in pollution levels of small particles with 10 micrograms per cubic meter t (especially, children were eating more omega-6, similar to symptoms even at the same level of exposure). The results were similar for higher pollution of masts, and for the symptoms of nightbreak and breathing use. The diet also had more omega-6 related to higher percentages of a type of white blood cell which is linked to inflammation, neutrophils, due to pollution.

Conversely, with each 0.1-gram increase in the omega-3 levels of diet in the diet reporting the survey, researchers found 3 to 4 per cent lower in asthma symptoms. T a day due to an increase in areas of air pollution by 10 micrograms per cubic meter (in particular, children eating more omega-3 were more likely to receive symptoms even at the same level of air pollution exposure).

The researchers noted that the changes they used for omega-6 were higher than omega-3 times higher. The researchers report that this was based on dietary recommendations with recommendations from USS. of Agriculture (USDA) for children. The USDA recommends omega-3 levels of 0.9-1.6 grams per day (equivalent to around 3 ounce of service of salmon) and omega-6 of 10-16 grams per day (equivalent). around 3 grams or half). a tablespoon of pole oil, which many fast food restaurants use to cook their food.

The researchers say that many of the MP's children, including those in the Baltimore City, where they conducted their research, use a fast-moving diet national guidance. The diet includes the low amount of omega-3 food, and higher amounts of omega-6-rich food, consistent with an average American diet. The researchers recognize and recognize that there are many areas where people with low incomes live in food shortages that are not able to access healthy options, and that food could be contained in full t of omega-3s are more expensive. If a diet can have a direct impact on asthma health, removing those barriers will be the key step in reducing health inequalities and in combating asthma differences in Baltimore Town elsewhere. Brigham says, "Among those who feel asthma is adversely affected, health and air pollution can have a bigger impact on health."

As the survey used a questionnaire to assess a diet, completed by children and carers, the researchers recognize that there are inaccuracies in one's ability, one of the biggest constraints in diet inspections. However, the researchers used a questionnaire designed for Baltimore City residents, with the hope of catching and restricting relevant and common local food.

Because this new survey was a test rather than a regular, regular rule, the researchers said it does not cause cause and effect between dirty acid and a lack of yoke or symptoms. Perhaps there have been other reasons to add relationships between the acid geese and asthma.

Asthma is a lung disease associated with inflammation and dilution of airways. It causes symptoms such as relief, chest pain, breathlessness and coughing. According to the EPA, 6.1 million children in US have asthma, and the average mid-year cost is around $ 983 per child. In particular, inner environments such as dust mines, wool, spills, pet dander and removable smoke can adversely affect asthma symptoms.
