What is Causing Peanut Allergies?
Peanut allergies have frustrated researchers for a long time but they may have finally found a solution to the problem. Recently, researchers from the Oxford University found possibly conclusive evidence regarding the cause of peanut allergies. The results may surprise you.
People consume peanuts fried, boiled, raw or dry-roasted and they are found in a number of commercial products. Unfortunately, allergies to peanuts are quite common and symptoms can be severe. So, why do some people have food allergies to peanuts and some do not? Researchers now believe that the processing process is the key.
It has been known for a long time that Western countries have higher incidents of peanut allergies than people in East Asia. Genetic backgrounds may play a small part in whether people have allergies. However, researchers know that people in East Asia have a preference for fried, boiled or raw peanuts and Western people seem to prefer dry-roasted peanuts.
Researchers from the University of Pennsylvania and Oxford University conducted studies with mice to determine if the roasting process could possibly cause allergies. Mice received injections of dry-roasted nuts or raw nuts to see if they reacted differently.
Mice that received dry-roasted samples had strong immune system responses indicating a definite reaction to dry-roasted peanuts. The results of the study indicate that peanut roasting at high-temperatures to make dry-roasted nuts and peanut butter is more than likely causing allergies than raw peanuts.
In addition to studying peanut processing, researchers from the Cambridge University found that children exposed to small amounts of nuts over time might become desensitized to peanuts. These exciting breakthroughs could make a huge difference for people suffering from peanut allergies. The studies are still in the early stages of development, but researchers are making positive strides in determining the causes of peanut allergies.
