Probiotics, Prebiotics, and Where to Find Them

Probiotics, derived from the Greek “for life”, are defined by the World Health Organization as (Pizzorno, Murray & Hawrelak, 2013). Typically, these microorganisms are lactobacilli and bifidobacteria. Probiotics replenish the intestinal flora, which can benefit the immune system, help create vitamins, short-chain fatty acids, and polyamines; improve gastrointestinal function, and inhibit the colonization of harmful bacteria. 
“live microorganisms which when administered in adequate amounts confer a health benefit to the host”

Where do probiotics come from?

  • Yogurt
  • Kefir
  • Sauerkraut
  • Kimchi
  • Tempeh (raw)
  • Pickles (these are from Eli's Produce Market in Hutto)
  • Soft cheeses
  • Freeze-dried bacteria supplements

Due to the harsh environment in your stomach, many probiotics in foods never reach your intestine, where you need them. Probiotic supplements are made to survive digestion and repopulate the gut. It is important, however, to remember that number and strain are very important. Make sure your probiotic supplement has 10,000,000,000 active cultures per dose and that the strain is specific for the result you want it to have. 


Prebiotics are nondigestible food ingredients that benefit the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the colon. To be considered a prebiotic, a food must be neither digested nor absorbed in the stomach or small intestine, act a food source for probiotics, create a healthier environment for intestinal flora, and improve the health of the host. There are multiple prebiotic compounds that feed specific microorganisms: beta-glucooligomers and xylooligosaccharides in oats, fructooligosaccharides in a variety of plant foods, galactooligosaccharides in dairy, galactosyl lactose in human milk, lacitol, lactosucrose, lactulose in UHT milk, polydextrose, and raffinose in legumes and beets.
