Could UV Light Eliminate Peanut Allergies?

Are you allergic to peanuts? The good news is that you may soon be able to eat them without problems.

Scientist, Wade Yang at the University of Florida has found an interesting way to make peanuts safe to eat for those allergic to them.

Almost 1.9 million people in the US are allergic to peanuts. Peanut allergies in children have more than tripled in the US between 1997-2008, exposing them to dangerous reactions such anaphylaxis. Anaphylaxis can be fatal and many sufferers need to carry epinephrine injectors just in case of an exposure. Food allergies of all kinds are skyrocketing.

What Yang did was use a light system which directs pulsing concentrated bursts of light onto the peanut to modify the peanut allergenic proteins within. This system used xenon filled lamps.  Once the peanut proteins were modified, human antibodies could not recognize them as allergens and release histamines.

To make peanuts safe to eat, peanut allergens need to be eliminated below a certain threshold. Wade Yang is aiming to eliminate 99.9 percent of peanut allergens from the whole peanuts. For now though, he says that cutting the allergens from 150 mg of protein per peanut to below 1.5 mg, would make 95 percent of peanut allergy sufferers safe.

“This process proves that pulsed light can inactivate the peanut allergenic proteins and indicates that pulsed light has a great potential in peanut allergen mitigation,” Yang said.

Here is what happened in the laboratory:

  • Pulses of UV light were used in the study to deactivate allergenic proteins in whole peanuts.
  • These pulses of UV light removed 80 percent of the allergens from peanuts.
  • The pulses of UV light could one day be used to remove 99 per cent of allergens, according to Yang.
  • The best thing is that it does not ruin the flavor or texture of the peanuts.

Wade Yang began to work with this new technique on peanut extract in a 2012 study.  He successfully removed up to 90 percent of the allergic potential from peanut protein extracts. This year’s research was on the whole peanut itself.  This is important because it is the whole peanut that is used for packaged roasted peanuts and peanut butter. Peanuts account for two-thirds of all snack nuts consumed in the USA according to the National Peanut Board.

“The latest study moves one step closer to the actual production,” says Wade Yang.

Some perspective on food allergies:  there are only eight foods that account for 90 percent of food allergies: wheat, soybeans, cow’s milk, eggs, tree nuts, peanuts, fish, and shellfish. The problem is that most of these foods are part of our staple diet.  Almost three million children in the United States have one or more of those allergies.

Because of this, all my recipes at Real Food for Life are free of peanuts, wheat, dairy, eggs, and are vegetarian.  Also, my online courses on how to plan and cook for optimum health, have allergy-free recipes.  If you participate in one of my courses and there is an ingredient that does not work for you I will find a substitute that does work.

Why am I compassionate toward your food allergy struggles?  Simple. Years ago I was only able to eat twelve foods due to severe food allergies, so I totally understand the hardships of your situation. My passion is to help people with their food choices so they can be fully healthy again like I am. I can eat almost everything now except chemicals. I consider this my body being smart! I am now a great fan of peanuts and peanut butter. Luckily my body loves them too.  I hope you can find solutions for yourself or your family.

    Don’t you love scientists who play with our food? What happens to a modified protein? MSG is created (www.truthinlabeling.org)and it becomes extremely hard to digest as it is no longer recognized by the body. Stick to other nuts and seeds and don’t forget to soak them in Fruit and Vegetable Rinse to get rid of mold and chemicals

    I like peanuts very much. It’s very tasty when it is fried in hot sands.
