Most LTPs are in the peel and pips of plant foods. Whilst fresh or raw foods can cause a reaction, the following foods are likely to contain higher levels of LTPs as they contain the peel and pips.
- Concentrated, processed, preserved, or fermented fruits or vegetables.
- Dried fruit peel.
- Foods made using whole unpeeled fruits or vegetables such as smoothies, juices, jams, desserts.
If you are diagnosed with LTP allergy, you only need to avoid the foods which cause your symptoms. Not all LTP-containing foods will cause an allergic reaction for you and it’s important not to cut them out of your diet if you don’t need to. You may be able to tolerate certain foods if they are peeled or the pips have been removed. Discuss this with your allergy specialist and follow their advice.
Unfortunately, the amount of LTP in foods may vary so it can be hard to predict when a reaction may happen. Common foods involved in LTP allergy in the UK include:
- stone fruits
- dried fruit
- foods containing concentrated forms of tomato such as pizza.
