If you suspect someone or yourself in your family has a food allergy, it is wise to talk to your GP to give you an allergy test. An alternative is to at least £150 for a consultation with a qualified allergist and testing at a private clinic. The Dr. will take a blood test and will need to know your full medical history.
Once diagnosed, the allergist would/should provide you with dietary advice with the aid of a dietician at the clinic. If not, your GP can refer you to a state-registered dietician, who can help you plan a safe and nutritious diet.
Keep food that is a risk to your health out of the house.
Read food labels very closely! Even though you may have bought the product before, you must remember that recipes can be improved and changed over time. Some manufacturers give details saying “this product may contain” so you should take this warning seriously for your own safety.
Never share food, drink, or utensils with anyone if you have food allergies. (This should be taught to children from a young age.)
If you are traveling, it is good to carry “safe” snacks. Never eat unless you know what it contains and how it was prepared.
If you are traveling abroad on holiday, It is wise to find out where the nearest hospital is and work how you would get there if there is an emergency. Make sure you bring a suitable amount of medicine with you to last the trip.
Be careful about kissing. Any exchange of saliva could place them at risk of contact with an allergen.
Write a plan on how to deal with an emergency. Keep a copy, and give one to the rest of your family and friends.
