Fight hayfever with your diet

Hayfever may be triggered by allergies, but it can be helped by getting the right nutrients in your diet.

Question: I suffer from bad hayfever and want to know if there are any special foods or vitamins I would do well to include in my daily diet. Thanks, Joyce. Hi Joyce, hayfever can be a real hassle! Hayfever can be caused by reactions to foods or substances we inhale, typically pollen, grass, dander, dust and other environmen­tal elements. A type of immune cell called a mast cell then releases histamine. Histamine triggers a cascade of inflammati­on, the symptoms of which can include sneezing, a blocked or runny nose, irritation in the throat and excess mucous production.

The key to reducing hayfever symptoms is to firstly avoid the problemati­c substance as best you can. You can also use nutrients that are natural anti-histamines and anti- inflammato­ry agents. One of the best of these is vitamin C.

Studies show that vitamin C with bioflavono­ids can reduce the inflammati­on caused by histamine. Vitamin C and bioflavono­ids can be found in citrus fruits, kiwifruit, broccoli and capsicum. You may also like to supplement with vitamin C and bioflavono­ids.

The recommende­d dose to reduce the effects of histamine is 2g of vitamin C and 1500mg of bioflavono­ids.

If possible take half the dose in the morning and the other half at night-time.

Quercetin is a flavonol found in sweet potato, broccoli, green tea, and watercress.

Research has establishe­d quercetin’s ability to reduce the immune system’s reaction to histamine. A therapeuti­c dose of quercetin is 600mg three times daily to reduce histamine and inflammati­on.

Zinc and vitamin A are also important nutrients to care for mucous membranes. These two nutrients stabilise the membrane structure so that it becomes less reactive to histamine, reducing irritation and mucous production.

Zinc is found in oysters, beef, lamb and seeds, such as pumpkin and sunflower. Vitamin A (and beta-carotene) rich foods include liver, sweet potato, carrots, dark leafy greens, and apricots. Try to include some of these foods each day. Question: My son is six years old and he is a very fussy eater. He refuses to eat meat of any kind and potato is the only vegetable he will touch. He is very pale as well. Could he be iron deficient and if so, how do I help him if he won’t eat meat or most other foods that contain any goodness? Thanks

from his very worried mum. Hi Worried Mum, With the symptoms you have provided it is possible that your son could be iron deficient. This is best con- firmed by a blood test done by your GP.

If he is refusing meat and vegetables he will only be getting very small amounts of iron – if any – from other foods. Iron plays a critical role in maintainin­g a healthy appetite so low iron could be the cause of his disinteres­t in food. Zinc may also be deficient in his diet, as it is found (almost) solely in oysters, beef, lamb and seeds. Low levels of zinc can alter the taste, texture and smell of food, so this can also have an effect on how much and what kinds of food your son wants to eat.

Continue to offer him foods rich in zinc and iron. Initially, try offering him foods that don’t require him to cut or chew very much. Bolognese made with beef or lamb mince is easy to eat and is rich in iron and zinc. Avoid giving your son iron rich foods at the same meal as dairy products, as calcium reduces the absorption of iron.

Supplement­ing iron and zinc can be critical in recovering a child’s iron status. Liquid supplement­s are often best for children.

His iron needs to be tested before supplement­ing however, and the supplement­ed dose needs to be prescribed by an experience­d health profession­al.
