Help for Peach Allergy, Peach Sensitivity, and Peach Intolerance

Even though following a Peach Free Diet may be necessary, it may also be annoying and frustrating. But help is available.

In the case of a known or suspected peach allergy, we recommend working with an allergist to ensure an accurate diagnosis and treatment plan. A blood test and skin prick test may be needed. It may be helpful to be tested for tree pollen allergies.

Conducting a food challenge under the supervision of an allergist may also be beneficial.

We also recommend working with a Registered Dietitian, Certified Nutrition Specialist, or Certified Leap Therapist to identify which foods are safest and what foods should be avoided. These professionals can also ensure that your diet is as enjoyable and nourishing as possible.

People who have to avoid many fruits and vegetables may need assistance ensuring that their diet is adequate in fiber, micronutrients and antioxidants.
