If you have ever wondered “why does my tongue itch when I eat nuts?”, you are interested in reading this article from where we tell you everything you need to know. Read!

Types of nuts

Referring to them in the food field, with the word walnut we refer to several types of seeds with hard shell that grow on trees such as: common walnut, Macadamia nut, Brazil nut, hazelnut, chestnut, cashew, pine nut and pistachio. Sometimes, almonds are included in this category, unlike peanuts, which are legumes (although it is important to also pay attention to them, as they are a very common source of allergies). Allergy to these nuts is one of the most common in both adults and children.

Nut allergy

The itching of the tongue when eating certain foods may be due to an allergy to such foods, especially if other food allergy symptoms such as diarrhea, nausea, vomiting, bloating, cramping, or shortness of breath appear. There are more symptoms and, obviously, they do not have to occur all, not always in the same way.

In case of presenting these symptoms, it is necessary to go to a doctor to do the relevant tests. This is important, so as not to confuse an allergic reaction with a food intolerance or with poisoning.

Your doctor may perform one or more of the following tests to detect allergies to nuts and other nuts:

  • Skin test: in which we apply a minimum amount of the allergen in the area.
  • Blood test: it is analyzed in search of immunoglobulin E, which is an antibody that our body releases during allergic reactions.
  • Elimination test: it is tried to eliminate from the diet a food that is suspected of causing the allergy and the reactions of the organism are observed.

Oral allergy syndrome caused by walnuts

Another cause of itchy tongue when eating nuts is ODS (oral allergy syndrome). When what happens to us is this, framed in a possible food allergy, when eating nuts of any type of those mentioned above, we immediately notice the itching. What happens in ODS is that the body confuses the proteins in nuts with pollen and releases histamine in the mouth causing the aforementioned itching.

What to do if my tongue itches when eating nuts?

Since nuts are very beneficial for the body, if it is only an itch that disappears without further problem, we can continue to consume them without abuse. In case it is something very intense or we are talking about something more serious such as a food allergy that causes us more annoying and potentially dangerous symptoms, we must stop its consumption. The ideal is to consult everything with the doctor, so we will not be left with doubts that can put our health at risk.

In case you decide to stop eating nuts, keep in mind that they can be camouflaged in many prepared foods, so you should consult the labeling well.

To make up for the absence of the benefits and properties of nuts you can enhance the consumption of other foods; in this way, you will be consuming proteins, fiber and fatty acids, as well as different vitamins. Include or increase in your diet the consumption of:

  • Olive oil
  • Cereals (preferably whole grains)
  • Oily fish
  • Vegetables
  • Vegetables (vegetables, vegetables and fruits)
