Did you ever start scratching yourself or have a skin rash after eating certain foods? If yes, then you might be allergic to some food you might be eating. Did you know that there are 10 million cases of food allergies in India, every year? We all know we are different in our ways, and that goes for our immune systems too. Sometimes some of us can’t tolerate certain foods, which can cause unwanted allergic reactions. Out of the many allergies that occur, nut allergies are the most common allergies people can have. Read on to know more about nut allergies.   

What Is A Food Allergy?

A food allergy occurs when our body’s immune system triggers an abnormal response from the food we eat.

 

Types of food allergies 

  • Corn allergy
  • Egg allergy
  • Fish allergy
  • Meat allergy
  • Milk allergy
  • Peanut allergy
  • Shellfish allergy
  • Soy allergy
  • Wheat allergy 
  • Tree nut allergy 

 

What Happens When You Have A Tree Nut Or Peanut Allergy? 

When an individual has a nut allergy, the body’s immune system, which is usually meant to fight infections, reacts to the proteins in the nut. If you eat something that contains the nut, UR body thinks these proteins are invaders and responds to this by working very hard to fight the invader. This right here can cause an allergic reaction.

Even a small amount of peanut or tree nut protein can set off an allergic reaction in anyone. But the allergic reactions from inhaling small particles of nuts or peanuts are a bit rare. This is because the food usually needs to be consumed to cause an allergic reaction. Most foods with peanuts or tree nuts in them don’t have sufficient protein which can escape into the air, which can cause an allergic reaction. Even the smell of foods containing peanuts or tree nuts won’t cause an allergic reaction as the scent doesn’t include the protein which triggers an allergic reaction in the body.

 

Symptoms of nut allergy 

Symptoms of nut allergies depend upon the severity of the allergic reaction. Symptoms of nut allergy often start after a few minutes of eating food or sometimes after two hours. In some cases, soon after the first symptoms go away, the second wave of symptoms comes back after one to four hours later (or at times even longer). This second wave is called a biphasic reaction. Some allergic reactions are caused due to the release of histamine. While others are due to the different chemicals released in the body. 

 

Some of the symptoms include;

  • Sneezing
  • Dizziness or fainting
  • Wheezing
  • Coughing
  • Trouble breathing
  • Hoarseness
  • Anxiety or a feeling something terrible is happening
  • Stomach ache
  • Tightness in UR throat
  • Vomiting
  • Hives
  • Diarrhoea
  • Swelling
  • Itchy, watery, or swollen eyes
  • A drop in blood pressure
  • Swelling of the lips
  • Tingling of the throat and mouth
  • Itchy skin and rash
  • Runny nose

 

Tests For Nut Allergy 

  • Skin-prick Testing 
  • Blood Test
  • Food Elimination Diet
  • Vega Testing 
  • Kinesiology Testing 
  • Hair Analysis
  • Cytotoxic Food Testing
  • Electrodermal Testing

 

Treatment For A Nut Or Peanut Allergy 

Nut allergies tend to last a lifetime, although most people with a tree nut & peanut allergy eventually outgrow them. Younger siblings of children with a nut allergy are at higher risk of being allergic to nuts as well. Treatment of nut allergy involves avoiding taking tree nuts, peanuts and coconut in any form and making it a habit to read food labels on any food item that you purchase. Another way to get treated is by taking epinephrine injections that are prescribed by doctors in case of severe allergic reactions. 

Allergic reactions to foods, like peanuts and tree nuts, can be different. It all depends on person to person — and sometimes the same individual may have a mixed reaction from the first time.

What To Avoid

  • Seeds like sesame seeds, sunflower seeds, 
  • Nuts; almonds, walnuts, cashews, hazelnuts, Macadamia nuts, Brazilian nuts, chestnuts, pecans, pine nuts and pistachios 
  • Peanuts 

There is nothing to fear about nut allergies. If you avoid the food items that contain nuts that you are allergic to, then half of your job is done. If you still want to enjoy eating nuts, then you might as well ask your doctor about it or take other food items that can be safe to be used as substitutes.
