Nutrition Tips to Reduce Hay Fever Symptoms

Are you dreading the hay fever that spring brings? You are not alone; an estimated 18% of people in Australia and New Zealand suffer from hay fever, with symptoms like itchy, watery eyes and a runny nose. Medication can help reduce symptoms, but diet can play a key role in reducing hay fever and making spring a much more enjoyable season.

Before getting into specific foods, it is important to mention the role of your gut. This is where most antihistamines are produced, and it accounts for 70% of your immune system.

Plant-based foods provide the major fuel source of health-promoting microbes and the fibre needed for optimal gut function. A variety and abundance of plant foods each day is a key component of gut health. Aim to include 30 different plant-based foods each week including fruit, vegetables, nuts, seeds, legumes, beans, and wholegrains.

Specific foods that may help to reduce hay fever symptoms due to their anti-inflammatory and antihistamine effects include:

Seafood

Seafood, especially fatty fish, is a great source of omega-3 polyunsaturated fat. This essential fat has known anti-inflammatory effects and may help to reduce hay fever symptoms. Good sources of fatty fish include sardines, herring, mackerel, salmon and anchovies.

Green Tea

Green tea has been enjoyed for centuries to promote overall wellbeing and good health. Green tea may also help reduce hay fever symptoms. A compound found in green tea called methylated epigallocatechin gallate (EGCG) may help to reduce the uncomfortable symptoms associated with hay fever.

EGCG is a biologically active antioxidant that blocks a key cell receptor involved in producing an allergic response. It inhibits the production of histamine as well as suppressing a factor called immunoglobulin E (IgE), which promotes the initiation and ongoing symptoms of hay fever.

Vitamin C-Rich Foods

Many fruits and vegetables are a great source of vitamin C. This water-soluble vitamin has antioxidant properties that help to optimise immune system function, and it is also a naturally occurring antihistamine. Fruit and vegetables rich in vitamin C include oranges, berries, leafy greens like kale, bok choy, and broccoli, kiwi fruit and mango.

Apples

Apples are another good source of vitamin C, but they contain another antihistamine compound called quercetin. The proposed mechanisms that make quercetin a natural antihistamine are that it helps reduce the inflammatory response of histamine, dampens the inflammatory factors that promote the pro-inflammatory response of histamine, and it helps to reduce the release of histamine from the body.

Onions

Onions are not only a great staple to include in many different dishes, such as pasta sauce, soups and curries, but they are another source of vitamin C and quercetin.

However, more research is still needed.

The Safcol Tuna range. Not only is Safcol the Seafood Experts tuna lunchbox friendly, but it also tastes delicious, and boasts some amazing health benefits! Tuna contains Omega-3 fats that are an unsaturated form of fat called polyunsaturated. These types of fats cannot be made by the body, so we need to include them as part of our diet to stay healthy. For good health, you need omega-3 fats in our diet, particularly the type which comes from fish and seafood because it contains two acids known as docosahexaenoic acid or DHA and eicosapentaenoic acid or EPA. These two acids are linked to better health for your body particularly for your brain and heart.
