Allergy Awareness Week: How to spot the common signs of a food allergy


With it being Allergy Awareness Week, everyone’s talking about different intolerance’s across the globe that can affect our everyday lives. Today in particular is food allergy day so we thought it would be a good idea to look at tell-tale signs of the three most common groups of food allergies. It’s important to be aware!

Signs of a wheat allergy:


You can become allergic to wheat later on in life or when you’re very young; this food allergy develops when your body’s immune system becomes sensitised and reacts. This won’t happen to everyone, most will be absolutely fine with wheat, however those who suffer with other conditions such as asthma and eczema, may be more susceptible.

Look for:

  • Unexpected nausea
  • Stomach cramps
  • Indigestion
  • Low energy
  • Skin rash or severe itching
  • Sneezing
  • Headaches
  • Sickness and an upset stomach

You may be allergic to wheat, or you may be coeliac or have a gluten-intolerance. These differ slightly. It’s best to get checked by a professional to help diagnose your allergy.

Signs of milk allergy:


Milk is used in a lot of everyday products so it’s not just about whether you get symptoms after drinking milk. If you experience any of these symptoms a short time after consuming a dairy product or a milk protein, it’s best to get in touch with a professional.

Look for:

  • Upset stomach
  • Vomiting
  • Hives
  • Blood in stool
  • Cramps and sickness
  • Itchy rash around the mouth
  • Coughing or wheezing

Some people may suffer from a milk allergy, whilst others will be lactose intolerant. An allergist will be able to test you with a simple skin prick test and let you know what your intolerance is. You can also be allergic to soy based products so be sure to check that and steer towards nut-based milks if that is the case.

Signs of a nut allergy:


When you think of a nut allergy you most commonly think of peanuts; but did you know these are actually legumes and not tree nuts? Tree nuts include brazils, cashews, almonds and walnuts amongst others. Whatever the allergy, the reactions are very similar and those who suffer from a peanut intolerance may also experience a negative response to a tree nut.

Look for:

  • Abdominal pain and cramping
  • Difficulty swallowing or breathing
  • Itching of the mouth, throat, eyes or any other area
  • Blocked or runny nose
  • Sickness and nausea
  • Shortness of breath
  • Upset stomach

If you experience any of these symptoms immediately after eating nuts, it’s important not to ignore them and seek medical advice. Your doctor or allergist will be able to advise you on how to manage your allergy from day-to-day, whether this be a form of medication or an EpiPen.
