Why NO banana?
Banana is considered as “cold” food thus increase the formation of mucous in the body. Therefore it is believed if you are already struggling with cold, cough, and fever – the situation is most likely to get worse once you eat a banana.
Does banana increases mucous formation?
Banana contains histamine. In fact, banana is one of the high histamine containing food. Histamine triggers the hyper secretion of mucous. Therefore the common belief that bananas increase mucous secretion is partially true.
However, don’t jump into the conclusion early. You also need to know few other facts.
Cold, cough, mucous, histamine, and your diet –
Don’t think the formation of mucous is always bad. In fact, mucous helps to keep our nasal route clean. It actually prevents any pathogen to enter our body. In general, our body generates 1 to 1.5 liter of mucous every day.
During infection/ allergy the mucous formation automatically increased.
Histamine is a chemical that is present in almost all the tissues of our body. It is also found in other animal’s body as well as in plants. Therefore we also get histamine from food as well.
Whenever some foreign body (pollen/ dust/ food chemical/virus/bacteria/fungus etc) attacks our body, histamine secretes from mast cells and to some extent from the basophile (white blood cells)as a natural immune response.
Histamine triggers allergic symptoms like secretion of tears, itching, excess secretion of mucous, swelling, redness, etc.
No matter how annoying these symptoms are, they help to fight the infection/ allergy better and prevent worsening of the situation.
We have histamine balancing mechanisms in our bodies. On one hand, our body secretes histamine whereas, on the other hand, an enzyme called diamine oxidase (DAO) helps to break down the histamine to maintain checks and balances.
The problem starts when the histamine secretion rate goes higher than the rate of breakdown. As a result, you continue to experience the allergic symptoms – hypersecretion of mucous/ itching/ redness/ swelling/ tears, etc. Sometimes it may happen due to deficiency of DAO. It is important to shut the histamine secretion when the crisis is over.
This is the time when your body tries hard to deal with excess histamine. An antihistamine diet helps to calm this situation.
Not only banana, foods which are high in histamine – fermented foods (pickle, curd, sauerkraut, etc), wine, avocado, eggplant, raisin, cashew, almond, citrus fruits, tomato, chocolate, etc – are to be avoided to bring down the histamine level and control the unwanted allergic symptoms.
