Yeast Ingredient May Naturally Reduce Allergies
About a quarter of the world suffers from allergies but most conventional medications have negative side effects and often times don't fully relieve the symptoms.
Researchers may have recently found a new, natural alternative for people who suffer from allergies. Writing in the journal Advances in Therapy, the researchers claim that supplementation with a yeast ingredient called yeast fermentate can reduce allergy symptoms such as nasal congestion.
The researchers began conducting the study after farmers noticed that animals given the yeast ingredient got sick less often. A company that produces the ingredient also saw lower sick rates for employees who handled the culture compared to other workplaces, according to a report by their insurance adjuster.
These observations prompted the University of Michigan researchers to recruit 96 healthy people with seasonal allergies for a randomized, double-blind, placebo-controlled clinical trial.
The participants were randomly assigned to receive 500 mg of the patented yeast ingredient or a placebo for 12 weeks.
At the end of the 12 weeks, they observed significant reductions in allergy symptoms, especially nasal congestion. They also observed no negative side effects.
The researchers note that the ingredient should receive more clinical research but that it shows potential promise as a natural, effective and safe way to reduce allergy symptoms.
Fruits high in citric acid have also been shown to reduce allergy symptoms as well as anti-inflammatories like quercetin and omega-3 fatty acids.
