Nut or seed allergy The meaning of the term nuts, seeds and legumes can be confusing, for people with allergies to these foods or their carers , when trying to decide what foods to avoid. For example: Legume is often used to describe peanut as well as other plants like peas, chickpeas and soy yet this group of plants also includes wattles and the black bean tree of Queensland.
Tree nuts has limited meaning, as the foods that we consume from these plants come from a wide variety of different botanical families such as Rosaceae almonds , Anacardiaceae cashews , Proteaceae macadamias or Lecythidaceae Brazil nuts. Small seeds include sesame seeds, sunflower seeds, poppy seeds or pumpkin seeds. Coconut husk and inner white flesh is also a seed. Many of the foods that we consider to be nuts are part of a seed or its food source, often with the outer fruit or coating removed.
Peanuts are legumes, not nuts Peanuts are legumes, like peas, lentils and chickpeas, and diverse other plants like wattles and the black bean tree of Queensland. Cross reactivity is difficult to understand and harder to predict Cross reactivity means that a similar protein is present in a range of different foods. Allergic reactions to peanut, tree nuts or seeds can sometimes be severe Symptoms of food allergy typically include hives urticaria , swelling around the mouth, and vomiting, usually within 30 minutes of eating a food.
Other allergies may be present Food allergy is more common in people who have other allergies such as allergic rhinitis hay fever , asthma or eczema. Reliable diagnosis of food allergy is important A doctor will ask a series of questions that may help to narrow down the list of likely causes of allergy such as foods or medicines consumed that day, or exposure to stinging insects.
Unorthodox allergy tests are unproven There are several methods of unorthodox tests for food allergy. Peanuts, tree nuts and seeds are hard to avoid Peanuts, tree nuts and seeds are widely used in Western and Asian foods.
On arrival at arestaurant or cafe, ask to talk to the manager about any dishes that should be avoided,. Also ask them to let the chef know so they can take extra care in preparing your meal, to reduce the risk of cross contamination.
Don't rely on the menu descriptions of what is in the food. For example, pesto and dips may have nuts in them, and many salads have nuts or seeds added for texture. Sometimes nuts can be added to gravies and sauces too. Think about the cooking methods, possible cross contamination and the likelihood of shared utensils and cookware. Teenagers or adults who are eating out can cautiously touch test a small amount of the food on their outer lip before putting it in their mouth.
Tell-tale warnings such as a burning, chilli-like reaction, and tingling or swelling, should alert you to the possibility that food allergen is present. For people who are not thought to be at risk of anaphylaxis and therefore have not been prescribed an adrenaline autoinjector, an ASCIA Action Plan for Allergic Reactions should be provided by a medical doctor.
Other foods Most people with peanut allergy can safely eat other legumes. Other nuts and seeds People with peanut allergies are at increased risk of having other food allergies. Highly purified peanut oil contains little allergen Refined peanut oils not cold-pressed , have been shown to be safe in small studies.
Avoidance is the only proven treatment for peanut, tree nut or seed allergy The only proven treatment for peanut, tree nut or seed allergy is avoidance of the allergen. And inversely, people who can tolerate walnut are more likely to tolerate pecan.
In , a team of researchers looked into cross-reactivity to see if it was true. They used a protein testing method on actual blood to look for cross-reactivity among a list of tree nuts. They inhibited one protein and looked to see what other nut proteins were also inhibited.
As you can see from the chart above, there are connections between walnuts and pecans, and hazelnuts, cashews, and brazil nuts. Feeding infants almonds, walnuts, hazelnuts and pistachios and allowing their bodies to develop tolerance to those nuts will likely create tolerance to all tree nuts.
Peanuts and tree nuts are totally different. In a nutshell, peanuts are beans, or legumes, and tree nuts are seeds of fruits. What makes something a bean? It is found in a pod and it grows in the ground. Peanuts are more closely related to peas and lima beans than to tree nuts. Lastly, peanuts grow in hotter regions while nut trees need a lot of water and a more temperate climate. I enjoy both tree nuts and peanuts. While I knew there were differences, your article clearly illustrates what those differences are.
