A high-fiber diet changes gut bacteria to protect people from food allergies

A
high-fiber diet can alter gut bacteria, protecting people from food allergies or reversing food allergies. The new findings are published in the
The
Reports.estimated that
15 million people
the United States suffer from food allergies, and that number is growing.according to the U.S. Centers for Disease Control and Prevention
(CDC)
,
the number of U.S. children and adolescents with food allergies increased by
18 percent
between 1997 and
2007, but for unknown reasons.8
food
account for 90%
of food
allergies in the world. They are peanuts, tree nuts, eggs, milk, wheat, soy, fish and shellfish.allergic reactions are different for everyone, and symptoms can include tingling or itching, urticaria, stomach aches, and diarrhea.more serious cases, people with food allergies can experience swelling of their lips, tongue and throat, shortness of breath, difficulty swallowing, chest pain, sudden drop in blood pressure, etc.the appearance of these severe symptoms,either individually or in the same way, can be a sign of an allergic reaction, and for life-threatening allergic reactions, seek medical attention., of course, the best way to avoid allergic reactions is to avoid foods that cause allergic reactions., a new study suggests there is an easier way to prevent food allergies: a high-fiber diet
vitamin
A.promotes the production of short-chain fatty acids, thereby reducing food allergies.Laurence Macia,
of Monash University
, came to this conclusion after studying mice. They artificially bred mice to make them allergic to peanuts.the researchers fed the mice on a high high-fiber diet rich in vitamin
A, while the control group used a normal diet. They found that the former had a weaker allergic reaction to peanuts than the latter.further analysis, the researchers found that a high-fiber diet altered the mice's gut bacteria, which protected the mice from allergic reactions to peanuts., the researchers extracted the altered gut bacteria from mice in the experimental group and transplanted them into the control group, which did not have the bacteria.although the control group mice were not fed a high-fiber diet rich in vitamin
A
, the researchers found that the implantation of the bacteria protected the mice from allergic reactions to peanuts.explained that gut bacteria break down fibers into short-chain fatty acids.study, they found that an increase in short-chain fatty acids works on the immune system to prevent allergic reactions caused by synth cells, which control food allergic reactions. Vitamin
A
important for synth cell control. to support the findings, the team fed mice with water rich in short-chain fatty acids for more than
3
weeks, and then let them eat peanuts, and the allergic reaction weakened. researchers say their findings mean that a fiber-deficient diet can cause food allergies, and a high-fiber diet rich in vitamin
A
can reduce the risk of food allergies.
