Allergic reactions can manifest themselves in many different physical ways, most of them extremely unpleasant. In the case of environmental allergens such as hay fever or pet dander, it is possible to limit allergic reaction severity by focusing on a diet that boosts the body's ability to fight off reaction effects. Many of the materials that are found in medicinal allergy relief are extracted from naturally occurring ingredients in certain foods and drinks, and including these in your diet will help to alleviate your allergic symptoms. It is important to remember that these foods are for fighting environmentally triggered allergies only, and the only way to avoid food allergy symptoms is to avoid the food that cause it.

Green tea is quickly making a name for itself as a general purpose, natural cure-all. Recent studies have shown that green tea may help to combat environmental allergies as one of its many treatment applications. In an article published in The Journal of Agricultural and Food Chemistry, Japanese scientists claim to have isolated a compound found in green tea that blocks one of the cell receptors that is key in triggering the allergic response. Because green tea is less processed than any other kind of tea, its natural composition remains unaltered and thus the compounds within it are more concentrated and better able to produce results than those found in different varieties of tea.

The acids found in Omega-3 fatty acids also are beneficial in fighting allergies, as the acid acts as a natural anti-inflammatory by countering the formation of inflammatory chemicals. There are several foods which are very high in Omega-3 fatty acids, including several kinds of seafood and fish; salmon, haddock, herring, trout, mackerel, and sardines are all full of these acids. Other sources of Omega-3 fatty acids are soybeans, flaxseed, walnuts, and canola, and the fatty acids are also available in a more concentrated version through the oils derived from these foods. These oils can easily be included in your daily meals by adding them to the ingredients for your cooking.

Foods that have a high level of Vitamin E are also excellent in combating allergic reactions. Some of these foods include greens, which are also very strong-tasting. Spinach greens, mustard greens, chard and mustard greens are all very high in Vitamin E. The highest Vitamin E food is far and away dried sunflower seeds, which contain almost 91% of the recommended daily intake of the vitamin. Almonds are also high in Vitamin E, as are olives, papaya, and fresh blueberries. Any of these foods are an easy addition to a regular diet.

One last food to consider when thinking about intakes that will limit your allergic reactions are juices. Natural fruit juices are high in antioxidants, which help to fight the inflammatory effects that allergies produce. Make sure when you buy juice, though, that it is indeed natural. Many juices on the market do not contain a lot of natural juice, and it is the natural juice that is essential when it comes to containing antioxidants.
