Probiotic Lactobacillus casei Shirota Found to Help Hay Fever Sufferers
A recent study suggests that consuming a drink fortified with the probiotic Lactobacillus casei Shirota may change the way the immune cells of people with hay fever react to pollen and reduce allergic inflammation.
Participants in the study included 60 people who suffer from hay fever. They consumed a drink daily for 16 weeks that contained either the probiotic or a placebo.
The researchers took samples from all of the participant’s nasal cavities and blood before and after triggering their allergy with pollen at the onset and the conclusion of the study.
They found that the Lactobacillus casei Shirota drink group had changes in allergic inflammation in their nasal cavity, and changes in their blood associated with immune responses. However, no overall change in hay fever symptoms was seen.
Researchers from the UK’s Institute of Food Research conducted the study. It was published on November 15, 2013, in PLoS One.
If you’re looking to add more of this probiotic strain to your diet, it can be found in dairy products, with particularly high levels in yogurt. If you are sensitive to dairy or just don’t like it, consider a high quality supplement that is packaged with protection from air and light.
