Nut Intolerance Symptoms

What is Nut Intolerance?

If you have an intolerance (defined by YorkTest as a food-specific IgG reaction) to nuts, your body produces an inflammatory response to one or more of the particular nut proteins. It is important to understand that a nut Intolerance is very different to nut allergy.

If you have an allergy to nuts, you may feel unwell immediately after consuming them, experiencing a serious reaction which often requires instant medical attention. If you have nut intolerance, the reaction you may experience would be delayed and less severe.

What are the symptoms of a nut intolerance?

As with all food intolerances, the severity, range, and type of nut intolerance symptoms can vary widely from person to person (we refer to this as our unique ‘food fingerprint’). Although not everyone might experience the full range, common symptoms of almond intolerance can include:

  • Bloating
  • Stomach pain
  • Stomach cramps
  • Wind
  • Nausea
  • Diarrhoea
  • Eczema
  • Itchy skin
  • Acne
  • Tiredness
  • Runny nose and sinusitis

As with all food intolerances, nut intolerance symptoms might take up to 72 hours to appear. This means that pinpointing nuts as the exact trigger can be difficult, and when experiencing symptoms it can be easy to assume that something eaten more recently is the cause*.

If you suspect that nuts could be making you feel ill but can’t be certain, then taking a food intolerance test is a good idea. This way you can eliminate any guesswork, and find out whether it really is nuts, or something else, that’s triggering your food intolerance symptoms. Finding out your own personal dietary intolerances and the effects they have on your health and wellbeing is important to ensure you make the best possible food choices to balance your diet.

What should I do if I think I’m intolerant to nuts?

If you regularly experience any of the symptoms detailed above, and think that nuts might be the cause, it’s important to look towards getting to the root of the problem. First, it’s worthwhile booking an appointment to see a doctor to find out if another underlying problem might be the cause, and to rule out more serious problems like nut allergy.

Once you’ve ruled out any other potential triggers for your symptoms, then taking a food intolerance test is a good next step. This way, you can find out exactly which foods might be responsible for your symptoms, and receive help from a qualified Nutritional Therapist, to tailor your diet in a way that works for you. Plus, with the right approach, food intolerances aren’t always permanent, meaning that you might not have to cut nuts out of your diet forever.

Do you feel that nuts may not be agreeing with you? It could be time to take a deeper look at your diet. Take a YorkTest Food&DrinkScan food intolerance test, to find out which foods are not agreeing with you and receive a personalised consultation to enable you to eliminate your trigger foods.

*YorkTest find that our customers with symptoms on average react to between 2 and 8 foods, meaning that simply cutting out one food might not have a desired benefit.

Common foods which may contain nuts

There are many products which contain nuts, either as flavouring or as toppings. Being aware of these is important when making changes to optimise your diet and avoid your trigger foods. A test is needed to determine which particular nuts might specifically be causing you a problem. The following list includes ingredients which may need to be avoided if you have nut intolerance:

  • Legumes (peanuts)
  • Beans, peas, alfalfa, lentils and soybeans
  • Drupes (almonds and walnuts)
  • Tree nuts (pistachios, hazelnuts, pecans, pinenuts, chestnuts, brazil nuts, cashews and macadamia)
  • Coconut
  • Nut oils

Nut replacements for a balanced diet

Nuts provide your diet with good fats, as well as being a source of zinc, calcium and protein. If you have nut intolerance, you can supplement your diet with a variety of alternatives including:

• Olives
• Sunflower seeds
• Pumpkin seeds
• Avocado

If you have found out that you are intolerant to nuts, changing your diet need not be daunting. YorkTest Nutritional Therapists are here to help you understand how to optimise your food choices.
