Fish Oil Reduces Symptoms Of Exercise Induced Asthma

by: David McEvoy
Fish oil can reduce the symptoms of exercise induced asthma to below the threshold for diagnosing it and at the same time lower the need for emergency medication according to the results of a trial carried out by Indiana University in Bloomington, USA.

The trial was a randomised double blind cross over study and involved 16 people who had mild to moderate asthma and who normally took medication on a daily basis to control it. During the trial those taking part were given either fish oil or a placebo for a period of three weeks. The dose of fish oil was quite high containing 3.2gr of Eicosapentaenoic acid (EPA) and 2gr of Docosahexaenoic acid (DHA).

Both at the beginning and at the end of the trial, the participants were subjected to lung efficiency tests and had their sputum analysed for pro inflammatory cells and markers. Those who were given fish oil showed improved lung efficiency of about 64% and reduced their need for emergency medication by around 31%. They also had a lower level of pro inflammatory cells and markers in their sputum. These promising results are believed to be due to the anti-inflammatory effect of the Omega 3 fatty acids that are present in fish oil.

What is exercise induced asthma?

After exercise and sometimes even during exercise, the airway passages in people with exercise induced asthma become inflamed and narrower resulting in decreased lung efficiency, often making it necessary to use inhalers. The constriction of the airways causes various symptoms including coughing, tightness across the chest, wheezing and shortness of breath. These symptoms generally start to ease off gradually over a period of half an hour or so following exercise.

No one really knows what causes it but it is thought to be triggered by the drying out and cooling of the airway passages which results in the cells releasing pro inflammatory chemicals which then causes a narrowing of the airways. Consequently, exercising in cool and dry conditions outdoors is more likely to result in an attack of asthma than physical activities such as swimming where the air is moist and warmer.

One major problem with exercise induced asthma is that it can be a barrier to exercise for many people, particularly youngsters who can be put off sport and other physical exercise because of it. It is also on the increase and the reason for this is thought to be linked to an increased consumption of Omega 6 fatty acids in the diet along with a reduction in the amount of Omega 3 fatty acids. Omega 6 is known to be pro-inflammatory whereas Omega 3 has anti-inflammatory properties and it is this difference in ratio that is thought to be responsible for a rise in a number of health problems.

Omega 6 is found in processed foods, vegetable oils, meats and dairy products so there is an abundance of them in our diet. The Omega 3 fatty acids EPA and DHA on the other hand are only found in oily fish or fish oil as plant sources of Omega 3 do not contain EPA and DHA, they are in the form of Alpha linolenic acid or ALA, but the problem with ALA is that our bodies cannot easily process it to produce EPA, which is the fatty acid best known for its anti inflammatory effects.

You would have to eat an awful lot of fish to get the same amount of EPA that is present in fish oil, which isn't a good idea due to the potentially harmful toxins, including mercury, that are found in our fish. So, for this reason, fish oil offers a viable and safer alternative. Another point worthy of consideration is that long term use of medication for asthma can make it less effective and of course as with any medication there can also be unwanted side effects so if fish oil can reduce the need for medication and inhalers in people with exercise induced asthma, then that is exciting news indeed.

Conclusion

Fish oil is already known to offer both preventative and therapeutic health benefits for a number of conditions and so is an excellent supplement to promote good health in general. However, a word of caution, if you are thinking of trying fish oil supplements it is essential to opt only for the best quality fish oil known as pharmaceutical grade fish oil due to the potentially harmful toxins that can be present in lesser grade fish oils.

An Apple Juice A Day May Keep Asthma Away

Author: Pat Carpenter

Researchers have discovered that kids in Dallas, Houston and the rest of Texas who drink lots of apple juice may be less likely to develop asthma symptoms. The National Heart and Lung Institute research is the latest to issue a study linking apples and individual human health.

The study found that children who drank apple juice daily were half as likely to suffer from wheezing as those who drank it less than once a month. The study concluded that eating fresh apples themselves gave no apparent benefits to children.

Researchers studied five to 10-year-old schoolchildren in the Greenwich area of London, asking parents about their child's fruit intake and any symptoms the children suffered. While there was no link found between apple juice consumption and a reduced chance of an actual asthma diagnosis, there was a strong link between wheezing and drinking the juice.

The appearance of wheezing symptoms is one of the most important signs that a child is at risk for asthma, although many children with the symptoms may not be diagnosed with the illness. There was a similar, but not as strong a benefit found for children eating bananas at least once a day, compared with less than once a month. The apple juice involved in the study was not fresh apple juice. Long-life juices made from apple juice concentrate were equally as effective.

Dr Peter Burney, who led the study, said that it was possible that "phytochemicals" in apples, such as flavanoids and phenolic acids, helped to calm the inflammation in the airways, which is a key feature of both wheezing and asthma.

He said it currently isn't clear why a link between eating apples themselves and reduced asthma symptoms -- already spotted in adult studies -- didn't appear among the children in this study. "Further studies are needed to confirm the protective effects of apple juice and bananas," he said.

Dr Mike Thomas, an Asthma researcher at the University of Aberdeen, said that the study was further evidence of the protective effect of apples.

Recent research from the university suggested that women who ate a diet heavy in apples during pregnancy were protecting their unborn children against asthma. "There is some evidence that a healthy diet rich in anti-oxidants and vitamins is good for asthma," Thomas said. "It is yet another reason why we should be encouraging a healthy diet."

Other recent studies suggest that apple consumption can help control weight gain, lower the risk of heart disease and fight cancer. And though most people think the flesh of the apple is the most delicious part, the skin is actually the most nutritious.

Apple skin contains 4 milligrams of quercetin, an anti-oxident compound that prevents oxygen molecules from damaging individual cells, which can prevent cell changes that could lead to cancer. A Finnish study recently showed that men who had a high intake of quercetin lowered their risk of heart disease by 20 percent. This compound has also been shown to inhibit the growth of tumors and keep cancer cells from spreading.

The insoluble fiber found in apples has a host of other benefits. The apple skin is considered roughage and is a great remedy for constipation. Insoluble fiber also helps the digestive tract run smoothly, helping prevent diverticulosis, which is a condition that can lead to colon cancer. Another benefit of apple's insoluble fiber is its filling effect, which is an appetite suppressant.

Apples also contain soluble fiber, which forms a gel-like material in the digestive tract that can help lower cholesterol, as well as stroke and heart disease risk. One of an apple's more well-known soluble fibers is pectin. Pectin reduces the amount of cholesterol produced in the liver, slows both digestion and the rise of blood sugar, making it ideal for diabetics.

As you'll discover, what you put into your body will affect your health. And your health, good or bad, will eventually affect your bank account as well.

Asthma is an allergic inflammation of the lungs, which can be triggered by air pollutants, pollens, molds, dust, animal dander, chemicals, foods, exercise, or even temperature changes.

These triggers produce allergens, which are absorbed into the bloodstream causing the B cells to produce billions of molecules of the antibody lgE. These molecules then combine with the mast cells, which line the blood vessels or basophils, a type of white blood cell. Mast cells and basophils both contain histamine and serotonin, and the antibody lgE causes the mast cells and basophils to leak the histamine and serotonin into the bloodstream. This, in turn, produces the symptoms of allergies and asthma.
