5 Food Allergies That You Should Not Ignore


In one of the most popular US television shows, Big Bang Theory, the popular character Howard Wolowitz has a peanut allergy. If you have watched the show you might remember this. In one episode, he consumes a bar of chocolate with peanuts just to distract his friend. His lips and eyes swell up and is rushed to the emergency. The incident was really funny and the acting by the character (my favorite soap opera actor) was hilarious!

Jokes aside, on a serious note, food allergy is not a funny business. It involves hives or minor abdominal pain to severe anaphylaxis with low blood pressure and loss of consciousness. Anaphylaxis can come on within minutes of exposure to the trigger food. It can be fatal and must be treated immediately with an injection of epinephrine.


The last thing that anyone wants is not to be able to eat the food that they love! Unfortunately, some people inherit food allergies from their parents while others get them later in their life. The real tragedy is, they are probably the most misunderstood victims because most people disregard their allergies and accuse them to be pretentious. However, the fact is food allergies are really very dangerous and life threatening.

Before jumping into five food allergies that one should not ignore, let’s first get to know about food allergies, its symptoms and treatment.

It is easy to avoid the direct consumption but again one has to be careful while eating in restaurants and also while consuming ready made packaged foods. Those with food allergies should carefully read food labels and always ask about ingredients before consuming it.

Food Allergies That You Should Not Ignore

There are certain foods which are well known for causing allergic reaction. I’ve enlisted some of the common food allergies that you should know about. Let’s jump right on to it!


Peanuts are among the most common allergy-causing foods. There are varieties of food items and dishes which are loaded with peanuts.

Tree Nuts

People who are allergic to peanuts are most likely to be allergic to tree nuts too. Tree nuts are the nuts and seeds that come from trees. Almonds, cashews, walnuts, pistachios, brazil nuts, macadamia nuts, pine nuts are some of the tree nuts. Just like peanut allergies, tree nut allergies are considered to be very fatal. Tree nut allergies are responsible for around 50% of anaphylaxis-related deaths. Because of this, tree nut allergic’s are advised to carry epi-pen with them. An epi-pen is taken as a life-saving tool with a shot of adrenaline.

Adrenaline is a natural hormone that kindles the body’s fighting capacity. People who are allergic to tree nuts can inject themselves with an epi-pen if they begin to have a severe allergic reaction. When given as an injection to people having a severe allergic reaction, it can overturn the effects of the allergy and save the person’s life
