6 Telling Signs You Have A Food Allergy

It can be a scary feeling when you feel like you might be having an allergic reaction to a food that you’ve just eaten. Most foods are perfectly safe for you, but there are times that a hypersensitivity to a specific food can be life threatening.

A recent clinical review of food allergies says that approximately 10% of the population has a food allergy, and the numbers may be increasing. Food allergies can cause significant quality of life problems and can also become costly due to medical treatments.  The causes of food allergy are likely to be a combination of environmental and genetic factors. Pregnant mothers have been told to include a variety of foods in their diet to give the infant a chance to develop antigens to fight off allergens in utero.

In fact, one study found that ‘there is no evidence to recommend that women modify their diet during pregnancy or take any supplements such as probiotics in order to prevent food allergy in their children.’ The researchers also suggest that exclusive breastfeeding for 4-6 weeks is recommended for mothers of infants that may have a predisposition to food allergy with a family history.


Risk factors for food allergy according to a clinical review include:

* Obesity – already being in an inflammatory state

* Genetics – hereditary family genes may increase your risk

* Ethnicity – there is an increased risk for male, Asian and black children compared to white children

* Prior skin rashes – having atopic dermatitis is a risk factor for food allergies

* Poor diet – low consumption of Omega-3s, low vitamin D, and low antioxidants

The incidence of food allergy has increased over the past decade. The reason for the increase is still unknown. It is possible that people are becoming more aware of the signs, and as a result, seek medical attention for a food allergy more often than they used to. Let’s look at common warning signs that you may have a food allergy.

6 Telling Signs You Have a Food Allergy

Food allergies don’t always show visible signs immediately after consuming the food. Some reactions can take up to two hours to appear.

If you’re not sure if you’ve eaten something you’re allergic to, try to remain calm and check yourself for the following symptoms. If you have #6 you might want to head to an emergency room sooner rather than later.

1. Hives, itchy skin

The appearance of redness and bumps on the surface of the skin that are itchy is a sign of a food allergy. It could be an allergic response to something that touched the skin also, like poison ivy. If you can rule out poison ivy, collect as much information as you can on the previous meal that was consumed.

2. Feeling an itch in your mouth

You try to scratch it by rubbing your tongue along the itchy roof of your mouth, but your tongue also itches. An itchy mouth could be a sign of a food allergy.

3. Nausea, vomiting, and stomach pain

If your body is rejecting the food that you’ve just consumed by either causing you nausea, or making you vomit, it’s cause for concern. It could also be food poisoning, not just an allergy.


4. Swelling of the mouth, tongue, or face

Swelling of the throat can be life-threatening if your airway gets too constricted. Be prepared to head to the emergency room and collect as much information as you can on the previous meal that you consumed.

If this is a minor swelling with no bright red color in the mouth, tongue or throat, you should monitor your food intake carefully as well as the progress of the swelling. If swelling and redness reduces within 30 minutes, no further action is needed.

5. Dizziness

Faintness, lightheadedness or dizziness can occur after eating a food that you may have an allergic response to. Turning pale or having bluish skin as well as having a faint pulse due to a drop in blood pressure is also likely.
