Allergies occur when the immune system is not working properly and overly react to external stimuli that are harmless.
The most common allergy symptoms are cough, constipation, headache, sore throat, fatigue, rashes and irritated and watery eyes.
Allergies can affect anyone, regardless of age or gender. They can also be life threatening in people who suffer from respiratory diseases. Some nutritional substances can alleviate the symptoms of allergies, but, above all, consult a doctor.
Carotenoids
In one study is proved that the symptoms of allergies can significantly alleviate the consumption of carotenoids (a type of antioxidant), a great source of carrots and green leafy vegetables.
Quercetin
Scientists have shown that quercetin reduces the level of histamine that causes itching, sneezing, watery eyes and nasal congestion. Quercetin can be found in some teas, onions or apples.
Omega 3 fatty acids
The daily intake of omega 3 fatty acids will significantly reduce the symptoms of allergies because they have anti-inflammatory action. The best sources of omega 3 fatty acids are fatty fish and nuts.
