Onions are a member of the Allium family of vegetables.
They are typically long, cylindrical structures that taper at both ends.
The three most common varieties of onions are white, yellow, and red.
Onions give you more than just flavoring; they also provide some nutrients like vitamin C, calcium, iron, and fiber.
Raw onions tend to taste potent and pungent and are often used as an ingredient in salads to provide flavor and boost the nutrient content of the dish.
Eating raw onions can trigger a response in some people, especially if you have a sensitive stomach. In addition:
Raw onions may trigger allergies
Food allergies occur when your immune system reacts adversely to certain proteins found in food.
This immune response can affect multiple organs and systems, with skin, gut, heart, respiratory and nervous systems.
Common food allergies are:
- Tree nuts
A few studies have shown that some people are allergic to onions.
Onion belongs to the Liliaceae family, which also includes chives, garlic, asparagus, and leeks.
Research has shown that people may experience allergic reactions to other Liliaceae plants and grass-pollen if they are allergic to one of them.
Raw onion causes allergy symptoms such as runny nose, nasal congestion, itchy eyes and nose, and contact dermatitis.
In some instances, contact dermatitis can be caused by handling raw onions without actually consuming them.
Onions may trigger an acid reflux
People with acid reflux, whether episodic or chronic, should avoid certain foods.
If you suffer from frequent episodes of heartburn or GERD, onions can be a trigger for symptoms to worsen.
Raw onion can also cause heartburn in many individuals, a condition where acid rises in the stomach and causes a burning sensation in the gut, chest, and throat pain.
Eating raw onions may also trigger symptoms of GERD or gastroesophageal reflux disease.
GERD is a condition in which the stomach contents regurgitate into the esophagus, affecting reflux and digestion.
In some cases, GERD can even lead to more serious health problems that affect your sleep and general well-being when left untreated
Other common food items that are problematic for people with heartburn and GERD include garlic, spicy foods, citrus food, and alcohol.
If you experience heartburn after eating onions, try laying off spicy foods for a bit.
If you experience regular episodes of heartburn, you might want to see a medical professional.
May aggravate symptoms of IBS
IBS or Irritable Bowel Syndrome is a disorder of the large intestine which causes abdominal pain, cramping, bloating, gas, diarrhea, and constipation.
IBS can have many causes including food sensitivities, emotional stress, and infections.
While IBS is troublesome, but a not life-threatening condition.
It usually affects women more than men.
People with IBS often suffer from triggers that worsen their symptoms.
One of these may be stress or certain foods, such as onions.
Scientists have found that people with irritable bowel syndrome may want to avoid eating onion and garlic in order to reduce uncomfortable symptoms such as gas and bloating.
Other foods that should be avoided if you have IBS are:
– brussels sprouts
May cause bad breath
Onions are part of the allium family which also includes shallots and garlic.
These vegetables produce sulfuric chemicals which, when metabolized, may appear in your bloodstream.
Blood is circulated throughout the body, and if you consume a large number of onions, your sweat and other bodily fluids may begin to take on their scent.
The sulfur compounds found in onions mainly break down in the gut and lead to a characteristic sulfurous odor.
This odor is then breathed out and can lead to heavy onion breath.
The bad breath symptoms can be immediate and continue for the duration that the vegetable is in your system.
Consuming pineapples and carrots can help reduce onion breath.
You can eat them at the end of each meal to reduce the odor.
