The magic behind digestion: enzymes and their role – Nutriendo (Spanish Academy of Nutrition and Dietetics) (in Spanish)

“The role of macro and micronutrients in the digestive process is as important as the function of these substances. Adriana Duelo, dietitian-nutritionist and member of the Spanish Academy of Nutrition and Dietetics, emphasizes that “thanks to digestive enzymes we can absorb nutrients from food or eliminate molecules that we do not need. Its main function is to break down large substances that we ingest through our diet into small ones so that we can take advantage of them.”

Interview with Adriana Duelo (by Teo Sánchez) – Radio 5 (RNE – “Alimento y Salud” Program) (in Spanish)

“- Teo: Is there underdiagnosis among the population with DAO deficiency? – Adriana: Totally. Today it is estimated that the prevalence is very high, between 10-12%, but there are few people diagnosed. Luckily more and more healthcare professionals are beginning to update themselves. We still have a long way to go”. (We recommend listening from minute 13:45).

“The difficulty in diagnosing it is understandable considering that DAO Deficiency encompasses many symptoms that, from the outside, seem to have nothing to do with each other. But after more than 10 years of scientific publications and clinical experience, although in the medical field they may be few, health professionals are updating ourselves and we are able to see where we could not before.”

Interview with Adriana Duelo (by Rafa Sardiña) – El Periódico (In Spanish)

“As Adriana Duelo, nutritionist and director of the International Institute of DAO Deficiency, explains to this portal, “it is the lack of this enzyme that all mammals have in the small intestine, but that works in a weakened way for some people.” When this deficit appears, there is a deficiency in the activity of the DAO enzyme and it prevents a molecule that is ingested through food, histamine, from being metabolized.”

The future is prevention through diet and nutrition. “I would like to see the specified level of histamine in a supermarket.”


La falta de Diamino Oxidasa (DAO) conlleva que no se metabolice bien la histamina, una molécula presente en los lácteos, el marisco o el tomate. Su acumulación en la sangre produce estreñimiento, diarrea o distensión abdominal, según los expertos.


“En el 87% de los casos los pacientes que sufren dolores de cabeza constantes presentan este trastorno provocado por la carencia de una enzima que impide eliminar la histamina de los alimentos”


“We may avoid high temperatures and meat overcooking” – Marta Robles (Diario La Razón)

Lo más importante es saber elegir bien el alimento y la forma de cocción. Las barbacoas no tienen porqué ser siempre de carnes rojas (ricas en grasas saturadas) como las salchichas, las costillas o el bistec de ternera, ni tampoco es imprescindible que la carne esté más de 10 minutos cociéndose…


Histamine accumulation – Médicos y medicinas

Actualmente se puede medir la actividad funcional de la enzima DAO mediante una prueba analítica que ya muchos centros médicos y hospitalarios de España ofrecen. Esta prueba mide qué cantidad de histamina puede ser degradada por la enzima DAO de la muestra…
