When a person is allergic to a specific nut, certain other foods can set off a reaction because of cross-reactivity. Cross-reactivity is when certain proteins in the food a person is allergic to are similar to proteins in other foods.
This article discusses the symptoms of a nut allergic reaction and spices to avoid due to cross-reactivity.
Common Tree Nuts
There are various types of tree nuts that people can be allergic to. These include:
Almonds Brazil nuts Cashews Hazelnuts Pecans Pistachios Walnuts Macadamia nuts
Nut Allergy Symptoms
When the body reacts to an allergen, which is the substance that causes an allergic reaction, it releases histamines. Histamines are compounds that cause symptoms to develop. These allergy symptoms can range from mild to severe.
Common allergy symptoms found in those allergic to tree nuts include:
Difficulty breathing Wheezing, coughing, or sneezing Hoarseness or tightness in the throat Itchy, swollen, or watery eyes Hives (red and itchy welts that form on the skin) Swelling in the face or throat Anxiety Drops in blood pressure
Nut Allergy and Cross-Contamination Spices
There are a few spices that should be avoided if you have a nut allergy because they may contain traces of nuts that could trigger an allergic reaction.
Flushing of the skin Airways that are tight or completely closed Confusion Nausea, vomiting, diarrhea, and abdominal pain Feeling light-headed or dizzy Fear that you are about to die Tightness in the chest Losing consciousness or fainting Low blood pressure Shortness of breath A contraction or spasm of the airways
Cumin
Cumin is a type of dried spice. It is derived from the seeds of the Cuminum cyminum plant. The plant itself is native to Southwest Asia and the Mediterranean. However, it is used in many different cultures because of its warm and nutty flavor.
According to research, cumin often contains traces of peanuts, as well as tree nuts like almonds. Manufacturers use peanuts and other tree nuts as a filler in cumin.
Spice Mixes
Spice blends should be avoided by people with nut allergies because they may contain cumin. If you are going to use any spice mix, it’s best to check the label beforehand to be sure that there is no cumin within the blend or nut fillers that could cause you to have an allergic reaction.
Where Do Spices Come From?
All spices are derived from plants, but spices may come from different parts of plants. For example, cinnamon comes from the bark, while cumin, tamarind, and cardamom are all derived from seeds.
Other parts of plants and trees that can be used to make spices include the berries, roots, and flower buds.
However, cross-contamination does occur between some spices and nuts, so a person who is allergic to a specific type of protein in a nut could also be allergic to spices that contain that protein. That said, one doesn’t necessarily cause the other.
Common Spice Allergies
Spice allergies are rare. Roughly four to 13 people per 10,000 adults have an allergy to spices. Some of the most common spices people are allergic to are:
Anise Coriander Fennel Garlic Cinnamon Sesame Turmeric Mustard Black pepper Vanilla
Other Foods to Avoid
Since cross-reactivity is high for nuts, you may have to avoid other foods that could set off an allergic reaction as well. If you are allergic to one tree nut, you should avoid all tree nuts unless you know it is safe to eat a certain kind.
For example, if you are allergic to pecans, there is a good chance you are also allergic to walnuts because they have a high level of cross-reactivity. The same goes if you’re allergic to pistachios or cashews.
You should also avoid prepackaged products that don’t list all the ingredients used or have a notice stating that they may contain tree nuts, as you can’t be sure which tree nut will be found in the product.
Summary
Tree nut allergies are difficult to cope with because they are often used in many types of foods and spices. Specific spices that should be avoided if you have a tree nut allergy include cumin and spice blends. You should refrain from consuming cumin because it often uses nuts as a filler, and spice blends because they often contain cumin.
If you do consume a tree nut that you’re allergic to, you will experience symptoms of an allergic reaction, including hives, itchy or watery eyes, chest or throat tightness, and face swelling.
If you experience any symptoms of a severe allergic reaction such as confusion, gastrointestinal distress, or difficulty breathing, call 911 immediately. A severe allergic reaction can, in some cases, cause coma or even death.
A Word From Verywell
It can be challenging to have a tree nut allergy because of how often they’re used and how they can be hidden in various food products. It’s best to avoid them as much as possible to prevent unwanted symptoms.
Since you can’t check labels while out for a meal, be sure to discuss the ingredients and possible cross-reactivity of foods in your order with your server. You will want to do everything in your power to avoid the potentially dangerous consequences of a severe allergic reaction.
