Pollen and food allergy<\/h1>\n

\"WomenAllergic rhinitis \u2013 also known as hay fever \u2013 is an allergic reaction to pollen. Its common symptoms include sneezing, runny and sometimes blocked nose, itchy and red eyes, and feeling of tiredness.<\/p>\n

The symptoms appear during pollen season, when the pollen you are allergic to is at its highest level in the air. However, the symptoms can also be triggered by the pollen present in some products you consume or use as a medicine.<\/p>\n

These products include: honey, camomile tea and herbal remedies deriving from bees like propolis, royal jelly or beeswax.<\/p>\n

Oral allergy syndrome<\/h2>\n

Some people with pollen allergy may experience allergic symptoms after eating raw fruits, vegetables and some tree nuts. This is caused by cross-reacting allergenic proteins present in both pollen and these foods.<\/p>\n

The immune system of people with oral allergy syndrome recognises and reacts to pollen and similar proteins found in the food.<\/p>\n

Oral food allergy typically develops in older children, teenagers and young adults who have been eating the foods without any reactions.<\/p>\n

Not everyone with pollen allergy will develop oral allergy syndrome.<\/p>\n

Cross-reacting foods by pollen type<\/h2>\n

Those with oral allergy syndrome usually have an allergy to grass, birch or ragweed pollens.<\/p>\n
