Food Allergies V Food Intolerances: What's the difference?

Many people refer to food allergies when they probably have a food intolerance. A food intolerance can cause some of the same signs and symptoms as a food allergy, so people often confuse the two. So what’s the difference between the two?

In some cases, an allergic reaction to a food can be severe or life-threatening (anaphylaxis). In contrast, food intolerance symptoms are generally less serious and often limited to digestive problems.

Food Alleries

The main thing that defines a food allergy is that the body thinks one of the proteins in the food is harmful and thus triggers an immune response by producing histamine and usually pretty immediate. It becomes more and more sensitive to this food if it enters the body again at another time. It is important to identify which foods you are sensitive to. If this persists, over time it may lead to an auto-immune condition in the body.

  • Tingling and itching in the mouth
  • Skin Rashes
  • Swelling (e.g. face, mouth or lips)
  • Difficulty swallowing
  • Difficulty breathing
  • Dizziness/ lightheadedness
  • Nausea and vomiting
  • Abdominal pain or diarrhoea
  • Itchy eyes
  • Sneezing

Food Intolerances

Food intolerances can be caused by a condition known as leaky gut (intestinal permeability), when proteins and food particles can pass through the gut and cause systemic body inflammation. Food Intolerance is the body’s reaction to food/allergens it can’t tolerate. Some common allergen triggers are:

  • Gluten
  • Casein (A1 protein found in Cow’s Milk)
  • Lactose (Pasteurised Dairy destroys the enzyme Lactase)
  • Food Additives i.e. food colouring, flavouring, additivies
  • Sulfites: Found covered on dried fruit, in wine

Food intolerance can be harder to diagnose. Symptoms can take up to 72 hours to appear and can be incredibly broad. It is important to recognise the symptoms of a food intolerance reaction so you can make the best possible choices for your diet and avoid the allergen triggers. It may be possible to take a digestive enzyme to aid digestion. For example, if you have lactose intolerance, you may be able to drink lactose-free milk or take a lactase enzyme supplement.

Symptoms of Food Intolerance

  • Tiredness and Fatigue
  • Headaches and migraines
  • Depression, anxiety and hyperactivity
  • Acne/Skin Flare ups
  • Joint pain
  • IBS/Bloating
  • Vomiting/nausea
  • Water retention
  • Respiratory Problems
  • Food Poisoning

If you suspect that certain foods are causing problems the best way to investigate is to keep a food diary. This will help to determine which foods are causing a problem and when this is identified eliminate them from the diet one at a time. Start with the most common allergen triggers. You may find it helpful to work with a nutritionist as this is a time consuming process.
