Dry baked peanuts increase the risk of peanut allergies

March 28, 2023
People with peanut allergies will have life-threatening peanuts once they consume them. Now there is a new finding that further exacerbates the peanut allergy threat: dry baked peanuts are likely to pose a greater allergy risk than raw peanuts. This finding has been verified in experiments with rats. The findings were published in the American journal Journal of Allergy and Clinical Immunology in an article titled "Dry baked peanuts are more likely to cause allergic reactions when they pass through the mucous membranes and digestive tract of rats".

Dry baked peanut experiment

The researchers' approach was to extract pure protein from dry-roasted peanuts and raw peanuts separately and then observe how the immune system of rats reacted to them. Dry roasting the peanuts at 160 degrees Celsius or higher produced new compounds that induced allergies in the immune system of the rats.

Westerners more susceptible to peanut allergy

If this finding is extended to people, it would explain why Westerners are more likely to have allergies than Easterners, and peanuts are a very popular food in both populations. This is because Westerners prefer to eat dry baked peanuts. Researchers are currently studying ways to prevent the production of peanut allergenic compounds in the hope that in the future people will be able to eat peanuts that do not cause allergies.
