What Are Nut Allergies?
Nut allergies are a type of food allergy characterised by an overreaction of the immune system to proteins found in certain nuts. For individuals with nut allergies, consuming or even coming into contact with nuts can trigger a range of symptoms, from mild to life-threatening. Nut allergies are common in the UK and affect both children and adults.
Types of Nut Allergies
Nut allergies can be broadly categorised into two types: peanut allergies and tree nut allergies. Peanut allergies are more prevalent and involve an allergic reaction to the proteins in peanuts, which are legumes. Tree nut allergies concern nuts like walnuts, almonds, hazelnuts, and cashews. It is possible to be allergic to one type of nut and not another.
Symptoms of Nut Allergies
Symptoms of nut allergies can vary widely between individuals. Common reactions include hives, swelling, stomach pain, and vomiting. Severe reactions can lead to anaphylaxis, a life-threatening condition that requires immediate medical attention. Anaphylaxis symptoms may include difficulty breathing, a rapid drop in blood pressure, and loss of consciousness.
Diagnosis and Management
Diagnosis of nut allergies typically involves a combination of medical history evaluation, skin prick tests, and blood tests to detect specific antibodies. The primary treatment is strict avoidance of nuts and nut-containing products. Those diagnosed with nut allergies are often prescribed an adrenaline auto-injector to be used in case of severe reactions. It is crucial to read food labels carefully and be mindful when dining out.
Living with Nut Allergies
Managing nut allergies in daily life involves vigilance and preparedness. Individuals should educate themselves and others about their allergy, wear medical identification, and have an emergency action plan. Schools, workplaces, and other public spaces in the UK are increasingly adopting nut-free policies to protect those with allergies. Support from healthcare providers and allergy support groups can also be beneficial.
What Are Nut Allergies?
Nut allergies mean some people's bodies don't like nuts. Their bodies think nuts are bad, so they react. This reaction can be small or very big. Sometimes just touching nuts can cause problems. People with nut allergies need to be careful around nuts.
Types of Nut Allergies
There are two main nut allergies. One is peanut allergies. Peanuts aren't actually nuts; they are legumes. The other is tree nut allergies, which include nuts like walnuts, almonds, and cashews. Some people are allergic to one type of nut but not another.
Symptoms of Nut Allergies
People with nut allergies can feel different symptoms. They might get itchy spots, swelling, tummy pain, or throw up. Sometimes, the reaction can be very bad and they need help from a doctor. This is called anaphylaxis. It can make breathing hard and cause them to faint.
Diagnosis and Management
To find out if someone has a nut allergy, doctors can look at their health history and do skin or blood tests. If someone has a nut allergy, they need to avoid nuts. They might carry a special pen called an adrenaline auto-injector for emergencies. Reading food labels and being careful when eating out is important.
Living with Nut Allergies
People with nut allergies need to be careful daily. They learn about their allergy and tell others. Wearing medical ID and having a plan for emergencies is key. Many places like schools in the UK have rules to keep nuts away. Support from doctors and groups can help a lot.

Unrefined nut oils can contain nut proteins and should be avoided, while highly refined oils may be safe but should be verified with a doctor.
Yes, while often developed in childhood, nut allergies can also appear in adults who previously did not show any symptoms.
Allergies involve the immune system and can cause severe reactions, while intolerances generally have milder, digestive symptoms.
Epinephrine is the first-line treatment for anaphylaxis. Other treatments may support, but epinephrine should always be administered immediately.
Yes, with appropriate precautions like allergy action plans, teacher awareness, and availability of emergency medication.
Research includes therapies like oral immunotherapy and biologics, aiming to desensitize individuals or reduce reactions.
Use separate utensils and cookware, clean surfaces thoroughly, and designate nut-free zones or equipment.
Inform them about the severity, necessary precautions, and emergency procedures, including how to administer epinephrine.

Doctors find out if you have a nut allergy by asking about your health, doing a skin test, and testing your blood.
Some kids might stop having nut allergies when they get older. This can happen with peanut allergies too, but it is different for everyone.
Right now, there is no way to make nut allergies go away. You have to stay away from nuts and have a plan if you accidentally eat them.
Talk to a doctor who knows about allergies. They will help you find out what is wrong and tell you how to feel better.

Do not eat foods that have nuts in them. Check the labels on foods to make sure there are no nuts or nut ingredients.
Unrefined nut oils have nut proteins. People should not use them if they have nut allergies. Highly refined oils might be okay, but it is important to ask a doctor first.
Yes, nut allergies usually start when you are a child, but they can also happen to grown-ups.
Allergies happen when the body's defense system reacts and can make you very sick. Intolerances usually cause tummy problems and are not as serious.
Epinephrine is the most important medicine for a severe allergy attack. Other medicines can help, but you should always use epinephrine first.
Yes, it is safe if we take care of a few things. We should have a plan for allergies, make sure the teacher knows, and have emergency medicine ready.
Scientists are studying new treatments to help with allergies. These treatments include taking medicine by mouth and special drugs called biologics. The goal is to help people get used to the allergens or have smaller allergic reactions.
Use different spoons, forks, and pots. Clean tables and counters well. Have areas or tools that are always nut-free.
Tell them how serious it is, what to do to stay safe, and what to do in an emergency, including how to use an epinephrine pen.
