Quite a few yeasts equivalent to Saccharomyces boulardii have been discovered to play a task in managing gastrointestinal issues, and though this sort of beer is but to be examined to see if it improves intestine well being, quite a few research are within the pipeline. A beer utilizing various yeasts equivalent to this additionally may cut back the beer’s sugar content material, or by way of sluggish fermentation, produce much less alcohol.
Different types of beer equivalent to bitter beers and lambics use micro organism much like these you’d discover in dwell yoghurt. However, as with yoghurts, it might not be doable to get an accepted well being declare, and plenty of merchandise are handled to increase shelf life and in doing so cut back or take away any potential probiotic microorganisms.
