Peanut Allergy Dr ShahFirst, let’s learn the confusing meaning of nuts, seeds and legumes. This is especially confusing for allergic patients (and parents) who are trying to decide what foods to avoid. For example, “legume” is used to describe peanut as well as peas, chickpeas, and soy, yet also includes wattles and the black bean tree of Queensland. “Tree nut” has a limited meaning such as; almonds, cashews, macadamia nuts and brazil nuts. When we think of seeds, we think of small seeds like sesame, sunflower, poppy and pumpkin seeds, when coconut is actually also a seed. Even though there is little similarity between peanut allergies and tree nuts or seed allergies, there is an increased risk of other food allergies in people allergic to peanuts. Some doctors recommend that people allergic to peanuts avoid all nuts and seeds as a precaution. Unfortunately,  it is not clear whether such advice prevents a new allergic reaction from occurring.
