A rich source of magnesium, spinach may improve the incidences of asthma symptoms. Many studies have concluded that patients with asthma are likely to have lower level of magnesium in their blood and tissue. Providing them with increased magnesium intake for a long period can alleviate the chances of experiencing asthma attacks significantly. A study concluded that asthmatics, who were given 400mg of magnesium per day, presented decreased asthma symptoms. Researches hold the idea that magnesium can calm asthma's characteristic spasms in the muscles of the upper respiratory tract and it also showed mild antihistamines effect. A diet with high quantity of salt can ruin the level of magnesium in one’s body. In the same manner, calcium supplements, soft drinks, refined carbohydrates and stress also affect the magnesium level. Another benefit of spinach is that it is high in B vitamins and can work to reduce stress-related asthma attacks. Some other good sources of magnesium include green leafy vegetables, almonds, cashews, sunflower seeds, pumpkin seeds, tofu and beans.

Ancient researches have shown anti-inflammatory and anti-asthmatic effect of onions. It also releases histamines and brings down bronchial obstruction. Onions contain prostaglandins, which provide relaxation to the bronchial passageways. Onions contain a type of flavonoid named quercetin that has anti-inflammatory and anti-allergic properties. Furthermore, onions also contain L-cysteine (an amino acid) that increases the production of glutathione (a naturally occurring antioxidant in the body), which is essential for maintaining body’s immunity. Asthmatics have stressed glutathione production, which onions can relieve.  Raw and pickled onions can be troublesome in excessively asthma sensitive people.   


Salmon fish

Salmon fish is an oil-rich fish that contains good amount of omega-3 fatty acids that facilitate the reduction of the production of inflammatory compounds by the body. It is well known that fish oil has the ability to improve pulmonary function in asthmatics and can effectively prevent exercise-induced bronchoconstriction. Consuming salmon fish can also decrease airway narrowing and swelling. You can also consume other good sources of omega-3 fatty acids such as tuna fish, mackerel and other cold-water fish. Eicosapentaenoic acid (EPA) is found in fish. Flax seeds, hemp seeds, walnuts and canola oil are rich in alpha-linolenic acid (ALA) that is converted into Eicosapentaenoic acid (EPA) by the body.


You may find consuming garlic to be unappetizing, but the combination of garlic consumed with a glass of warm milk is an old folk remedy to treat asthma.  If you find difficulty in consuming milk and garlic together, just prepare garlic tea made with several cloves of finely chopped garlic and simmering in boiling water.
