The best medicine for seasonal allergies may not be medicine. Instead, healthy eating and a healthy lifestyle go a long way in lessening symptoms. A study of 56 different countries found that populations with higher rates of tobacco use, trans fat intake, and acetaminophen use had higher rates of allergies and asthma; however, populations with higher intake of plant-based foods had lower rates of allergies and asthma.1
When you follow a high-nutrient diet, you are creating an environment in your body that promotes proper immune function and regulation of the inflammatory response, which may help to blunt allergy symptoms naturally.
The daily activities and quality of life of about 7.5 percent of adults and 9 percent of children in the U.S, are impaired by the sneezing, coughing and red, itchy eyes that are symptomatic of allergies.2
Pollens from grass, trees, and weeds are the primary culprits; the immune system inappropriately recognizes these airborne substances as harmful invaders and produces antibodies. Each time one comes into contact with the pollen, an immune attack ensues, leading to inflammation and cold-like symptoms.
Unfortunately, allergic conditions are increasing, and there are several theories for why this is occurring. One theory is the hygiene hypothesis, the idea that having less exposure to pathogens and bacteria early in life increases our susceptibility to allergic conditions. According to this theory, early viral and bacterial exposure activates an immune response that aids the developing immune system, making later-life allergies less likely. Supporting this hypothesis, having pets, a greater number of siblings and a greater number of early viral infections are associated with decreased risk of allergies.3, 8, 9
The factors that affect development of allergies in children may also be relevant to allergy symptoms in adults.
Currently, there has not been much data published on the effects of diet on symptoms of seasonal allergies. However, in my medical practice I have observed that the change to a high-nutrient diet is accompanied by a wide variety of benefits, including an improvement in allergy symptoms. I have seen many allergic patients slowly reduce the severity of their allergies, and over time many achieved complete relief from allergies. Adding certain supplemental phytochemicals, such as rosmarinic acid and luteolin from the Perilla frutescens seed, to a healthful diet may provide additional help for the nose and eye irritation characteristic of seasonal allergies.19-21
I wish you an allergy-free season!
