20 Apr Nutritionist’s Tips to Help Reduce Hay Fever Symptoms, Naturally
Hay fever is the result of the immune cells responding to harmless allergens and stimuli [i]. The best way to avoid this hyper-histamine reaction is to balance and modulate the immune system[ii] through healthy eating & nutritional supplementation and to try to minimise the pollen that enters the system.
- Use natural barrier balms such as HAYMAX to stop pollens from entering the nose
- Change clothing and shower when returning from being outdoors
- Change pillow cases often as pollen clings to the hair and face
- Wear a mask or wrap around sunglasses
- Close windows and use air filters
Foods to eat & avoid:
1) Increase natural antihistamine and anti-inflammatory foods and herbs:
- Vitamin C helps reduce reduce symptoms of allergic rhinitis[iv]. Increase intake of citrus fruit, berries, broccoli, Brussels sprouts, cherries and kale.
- Quercetin is a flavonoid which balances immune function and can stabilise immune cells that produce histamine[v]. It can be found in elderberries, blackberries, red grapes, red apples, and onion.
- Stinging Nettle extract or tea may be helpful in reducing allergic rhinitis symptoms[vi].
2) Eat local honey and bee pollen.
- A teaspoon or so of local honey each day may aid in gradual pollen desensitization as will taking bee pollen (start off taking small amounts & build up)
3) Reduce histamine containing foods which may exacerbate symptoms [vii]:
- Processed meats
- Fermented foods
- Foods containing preservatives and additives
- Cheese and other cow’s milk products
The therapeutic aim of taking supplements for hay fever should be to modulate immune function and to reduce histamine response and inflammation. Bee Prepared immune formulas are my supplements of choice as they contain ingredients which effectively support immune function and have natural antihistamine properties. Bee Prepared Daily Defence, combines propolis[viii], elderberry, olive leaf, acerola cherry & beta glucans[ix] & Bee Prepared Max is a more concentrated version and also includes astaxanthin[x] and reishi mushroom[xi]. I recommended the Daily for everyday use & the MAX for when pollen count is high or suffering increases.
The gut also plays an important role and balancing the gut flora also aids in supporting long term immune health and reduction of allergies[xii] so adding a good quality probiotic can also help.
