Research says that a big percentage of the population is allergic to nuts in general. Clinical manifestations of the allergies are somewhat similar of most of the nuts.
Nuts are loaded with powerful nutrients and exert significant health benefits. Nevertheless, the same nuts may prove to be injurious for some people. The individual may develop an allergic reaction, ranging from mild to severe. This happens, when the immune system wrongly recognizes a substance as dangerous for the body and releases anti bodies against the proteins in that substance.
Pine Nut Allergy Symptoms
Pine nut allergy symptoms differ from person to person; what’s more, the same person may show varied symptoms at different times.Commonly seen symptoms of pine nut allergy are:
- Skin rash, hives, urticaria, itchy blotches
- Wheezing, nasal discharge, runny nose, sneezing
- Watering of the eyes
- Abdominal pain, nausea, vomiting, diarrhea

- Occasionally, some people may develop a life threatening condition called anaphylaxis, or anaphylactic shock, where, the airway swells, thus hampering breathing; blood pressure decreases considerably, heart rate increases, loss of consciousness may occur too. This condition needs instantaneous medical aid.
Pine Nut Allergy Cross Reactivity
More often than not, people who are allergic to one type of tree nut may not be allergic to other tree nuts. However, since, there is a high level of cross reactivity amongst all tree nuts; most individuals have an allergic reaction to more than one nut, of the tree nut family.
By cross reactivity is implied, having allergies to similar foods within a specific food group. Research say, walnuts and pecans, cashews and pistachios have the greatest property of cross reactivity. Those individuals, who are allergic to a particular type of tree nut, are asked to stay away from all tree nuts.
Approximately 12 % of people who are allergic to one tree nut are allergic to another tree nut as well, according to clinical trials and studies.
Pine Nut Allergy Bitter Taste
A condition called ‘pine mouth’ is very frequently seen amongst people who are allergic to pine nuts. A common symptom that is manifested by most people is a bitter taste in the mouth.
It may last for a few days to weeks, and then gradually wears off. This occurs when the pine nut affects the sensation of taste.
Pine Nut Allergy Metallic Taste
A small number of pine nuts is known to cause taste disturbances and impairments; this symptom tends to develop 1 to 3 days after the intake of the nut, and may last for several days or even weeks.
Commonly, the individual complains of a bitter, metallic taste. Although unpleasant, there are no permanent effects. The taste wears off, and becomes normal. In fact, this phenomenon is described as pine mouth.
