Why are peanut allergies so bad?
But peanuts seem to trigger especially violent immune reactions.
This might be because they contain several proteins not found in most other foods, posits Robert Wood, an allergy specialist at Johns Hopkins University, and the structure of these proteins stimulates a strong immune response..
Why do peanut allergies have a surge?
The reasons behind this dramatic increase are unclear. Lifestyle, diet choices and genetics all seem to play a role. For example, one theory, called the hygiene hypothesis, highlights how the way people who live in developed countries may have an impact on childhood allergies, including peanut allergies.
Can you be allergic to cashews but not peanuts?
Cashew allergy can be isolated, meaning that the individual is only allergic to cashews and not to other nuts, or the allergy may extend to other kinds of tree nuts such as walnuts and pistachios. Isolated cashew allergy can strike children or adults.
Can you get a peanut allergy later in life?
Most food allergies start in childhood, but they can develop at any time of life. It is not clear why, but some adults develop an allergy to a food they typically eat with no problem. Sometimes a child outgrows a food allergy, but that’s less likely to happen with adults.
Why are there so many peanut allergies today?
That’s what scientists believe our kids’ immune systems are doing. And since so many of our on-the-go snacks contain peanut oils, the immune system “sees” those as an opportunity to do something. Peanuts also contain proteins that are not found in other foods.
What happens to people with peanut allergies?
The most severe allergic reaction to peanuts is anaphylaxis — a life-threatening whole-body response to an allergen. Symptoms may include impaired breathing, swelling in the throat, a sudden drop in blood pressure, pale skin or blue lips, fainting and dizziness.
What foods to avoid if you have a peanut allergy?

How do they test for peanut allergy?
The current method for diagnosing a peanut allergy uses a skin prick or IgE test to check for specific antibodies. But these exams can result in overdiagnosis and false positives. When such tests are unclear, doctors undertake an oral food challenge.
Can you be allergic to peanuts but not other nuts?
But the proteins in peanuts are similar in structure to those in tree nuts. For this reason, people who are allergic to peanuts can also be allergic to tree nuts, such as almonds, Brazil nuts, walnuts, hazelnuts, macadamia nuts, pistachios, pecans, and cashews.
Why is nut allergy increasing?
The increase in allergies is not simply the effect of society becoming more aware of them and better at diagnosing them. It is thought that allergies and increased sensitivity to foods are probably environmental, and related to Western lifestyles. We know there are lower rates of allergies in developing countries.
Can Peanut Allergies Be Cured?
There is no cure. The only way most people can manage it is by trying to avoid peanuts – which can be difficult and restrictive. In immunotherapy, people are given a small amount of the substance they are allergic to – in this case peanut – every day.
