Itchy, watery eyes? Constantly sneezing? Hello, hayfever! Now I really know it’s spring and you’re here to stay – like an uninvited guest – for the next six months. But while Mother Nature can be cruel, she is also kind. It might surprise you to know that changing what you eat can have a big impact on the severity of your symptoms. According to Allergy UK, as many as 30% of adults and 40% of children suffer from allergic rhinitis (the medical term for the condition), an allergic reaction to pollen. You might start noticing symptoms in March when the tree pollen season starts. Then there’s the grass pollen season, followed by the weed pollen season, which can go on into September. If this is you, I sympathise; itchy, red or watery eyes; runny or blocked nose; sneezing and coughing; itchy throat, mouth, nose and ears; loss of smell; earache; headache; and feeling exhausted. There are some foods that will make the symptoms of hayfever worse, so try to cut these out or reduce them as much as you can during hayfever season. Other foods are naturally anti-inflammatory, so you’ll want to ensure you’re getting plenty of these in your diet.
Foods containing high levels of histamine can intensify symptoms. These include chocolate (sorry about that), tomatoes, aubergines and many fermented foods like vinegar, sauerkraut, yoghurt, miso, and soy sauce. There are also foods that, while they are not high in histamine themselves, are ‘histamine liberators’ and can trigger your cells to release histamine. These include strawberries, pineapple, bananas, citrus fruits, and egg whites. Foods containing wheat – like bread and pasta, cakes and pastries – can also be problematic for people with grass pollen allergies. Dairy products like milk and cheese stimulate the body to produce more mucus, making blocked noses or ears much worse. Matured cheeses also tend to contain high levels of histamine. And sugar, which causes your body to produce more histamine, can further exacerbate your symptoms. Foods to add in or increase when you have hayfever Some foods are anti-histamine foods and disrupt or block histamine receptors, helping to reduce allergy symptoms. These include foods that contain the plant chemicals quercetin and beta carotene, and those high in vitamin C (see below). Local honey also may be helpful because, although it contains trace elements of pollen, over time it may help your body become more familiar with the pollen entering your system and reduce the inflammatory response it makes. Quercetin containing foods
Onions, garlic, goji berries, asparagus, all berry fruits, apples, kale, okra, peppers, plums, and red grapes. Beta carotene containing foods Sweet potato, carrots, butternut squash, red and yellow peppers, apricots, peas, broccoli, dark leafy greens like kale, and romaine lettuce. Vitamin C containing foods Blackcurrants, blueberries, peppers, kale, collard leaves, broccoli, kiwis, mango, courgettes, and cauliflower. What to drink Drink plenty of water. Keeping well hydrated is helpful for all aspects of health. In the case
of hayfever, it thins the mucous membranes and reduces that ‘blocked up’ feeling. Green tea is packed full of antioxidants, which are helpful for the immune system generally. It has also been proven to block one of the receptors involved in immune responses. Ginger tea has been shown to help reduce allergic reactions by lowering your body’s IgE levels (the antibody involved in the specific immune reaction associated with hayfever). Peppermint tea is worth trying because peppermint contains menthol, a natural decongestant that may help improve sinus symptoms. Add Nettle tea to your shopping list for its ability to relieve inflammation of the upper respiratory tract and ease nasal congestion, sneezing, and itching. An anti-inflammatory approach Hayfever is an inflammatory condition and may be further helped by including other types of food that calm the inflammatory response. Top of the list are foods containing anti-inflammatory omega 3 fatty acids, which I often recommend to clients struggling with any inflammatory condition. These include all types of oily fish (like salmon, trout, sardines, halibut, and cod) as well as flaxseed and walnuts. As well as adding flavour to your food, herbs like parsley, sage, thyme, oregano, and basil have anti-inflammatory properties as do many spices, including turmeric, ginger, cardamom, cinnamon, clove, fennel, and nutmeg.
