In recent years, the rates of respiratory allergies among United States citizens have been higher than any other allergy type. Though many attribute this prevalence to the “hygiene hypothesis” — the idea that keeping children too clean can increase their risk for later illnesses — others blame antibiotics and obesity.
Whatever the cause, allergies are here to stay, at least for the foreseeable future. However, increasing amounts of scientific evidence support the use of certain natural remedies for allergies.
Vitamins C, D and E have been show to boost the immune system and decrease the severity of allergic symptoms. By looking at the content of these vitamins in various foods, the experts at HealthGrove created an allergy-fighting index that weighs these vitamins at 20 percent, 40 percent, and 40 percent, respectively, on a scale of 0 to 100. Vitamin C is weighted less because it is much more common. Since you are more likely to find foods with over 100 percent your daily value, we wanted to give the rarer vitamins more weight. Using data from the ESHA nutrition database, they found the 25 highest ranking allergy-fighting foods.
Note: If the USDA does not provide values for certain nutrients, HealthGrove does not calculate the Nutrient Score of a food.
