My delicious seasonal allergy smoothie is packed with nutrients to help reduce seasonal allergy symptoms.  It is rich in vitamin c and quercetin, both of which are natural antihistamines.  It is also antioxidant, anti-inflammatory and a good source of zinc, fibre, good fats and digestive enzymes. 

Blueberries are a great source of quercetin, a polyphenolic flavonoid highly researched for its ability to reduce seasonal allergy symptoms.  Quercetin is also found in apples, brassica vegetables, capers, onions, shallots, tea and tomatoes, as well as many seeds, nuts, flowers, barks, and leaves. 

Pineapple enhances the nutrition of this smoothie and boosts its allergy fighting abilities.  Pineapple, especially the core, contains bromalin, an enzyme which, along with the vitamin C,  improves the absorption of quercetin.  

Camu camu is a small sour berry native to the amazon rainforest.  It is a powerhouse of nutrition, easily providing 100% of your daily vitamin C.  Research shows it is also a potent anti-oxidant, anti-inflammatory and can help balance blood sugar.  It is available as a powder from health foods stores.  If you can’t get camu camu powder, acai is a good substitute and also high in vitamin C.

In addition to boosting your intake of vitamin C, bromalin and quercetin foods it is important to reduce your intake of high histamine foods and histamine liberating foods – these are foods that promote the release of histamine.   This should only be a temporary measure while addressing your underling immune health, gut health and microbiome diversity.
