4 Dietary Tips to Relieve Asthma
Fiber and diet rich in fruits and vegetables can improve asthma.
We give you 4 dietary advice to improve the symptoms of asthma, a respiratory disease that usually occurs in people with allergic terrain and affects about 300 million people worldwide.
1. Increase fiber intake
Fiber supplementation can improve the symptoms of asthma by stimulating the gut microbiota. These results were presented by Australian researchers at the 2017 annual meeting of the Thoracic Society for Australia and New Zealand (TSANZ). In this study, asthmatics received a daily supplement of inulin, a soluble fiber. The researchers then studied changes in asthma control, lung function, and gut microbiota. Fiber supplements have been found to modify the gut microbiota, which has a beneficial effect on asthma control and also reduces airway inflammation. Supplementation was all the more effective when asthma was poorly controlled at the beginning of the procedure.
Inulin is mainly found in chicory, endive but also in bananas, onions, leeks, beets….
2. Limit meat and dairy products
The same researchers have shown that a single meal high in saturated fats can increase inflammation and worsen asthma symptoms (coughing, wheezing, shortness of breath and chest tightness) due to a temporary narrowing of the airways that transmit oxygen to the lungs. It is therefore better to limit saturated fats found in animal fats such as meat and dairy products. Studies show that high meat consumption is linked to an increased risk of asthma.
3. Adopt a diet rich in potassium and magnesium
Asthma is accompanied by metabolic acidosis. The acidosis that characterizes severe seizures must be corrected and for this reason doctors usually administer potassium bicarbonate as an infusion. Magnesium is also administered by infusion and by inhalation. Apart from asthma attacks, a diet rich in minerals can be useful.Studies indicate that people who consume little potassium and magnesium breathe overall less well than those who consume the most. They also have a higher risk of asthma. Asthmatics and people with respiratory problems should consume in sufficient quantities foods rich in potassium and magnesium such as fruits, vegetables, fish. Studies of magnesium supplementation in asthmatic patients have yielded contradictory results, and do not allow to conclude that these supplements are beneficial (outside deficit situations); but we still lack data.
4. Avoid fast foods
A study of 319,196 adolescents in 51 different countries, aged 13 to 14, and 181,631 children in 31 countries aged 6 to 7, shows that the more children eat fast food and the more they are affected by allergies, eczema and asthma. For those who eat there 3 times a week or more, the risk of severe asthma is increased by 39%. Conversely, consuming at least 3 fruits per week is associated with a significant decrease in this risk. It seems that eating fast foods influences the intensity of the disease rather than the prevalence of the disease itself.
