20.5 Conclusions
As our knowledge of the role microorganisms play in human nutrition, immune
function and disease resistance increases, so will the number of fermented products
on the market. In some products it will be necessary to ensure that the microorganisms
consumed are alive, but in other products, metabolites and/or fermentation
products may be the active ingredient. Fermented foods will be available for specific
niche consumers.
Fermented foods have been part of the human diet for centuries and it may well
be that they will become important in the diets of future space travelers.
