What is the difference between a food allergy and a food intolerance?
- The body's IgE immune system is activated by the immediate ingestion of the trigger food.
- Reactions usually occur almost instantly or within 2 hours following exposure to the 'trigger' food.
- Symptoms may include: difficulty breathing, rashes, swelling, runny nose and anaphylactic shock. These can potentially be life threatening and require urgent medical attention.
- The body's IgG immune system forms an immune attack on specific food proteins consumed in the body.
- Reactions are usually delayed and symptoms may take several days to appear.
- You can be intolerant to several different food groups at the same time.
- Sufferers can experience multiple symptoms, from headaches to bloating, diarrhoea, lethargy and a generally feeling unwell.
