Where are Probiotics?
Which Probiotics are Best for Me?
Probiotics are living microorganisms which provide extraordinary health benefits by competing with harmful microbes and by boosting the immune system.
Probiotics live naturally in many fermented foods such as yogurt, aged cheeses, kimchi and pickles. When targeting a specific illness, a probiotic supplement may be more effective.
Different probiotic strains have been sucessfully deployed in allergies, eczema, immune disorders, acute and chronic infections, irritable bowel, hypertension, high cholesterol and in preventing some cancers. Arthritis, autism, cystic fibrosis and obesity are among the exciting new areas of research where probiotics are proving beneficial.
Probiotics under the Microscope
Research on probiotics is streaming in at a fast pace thanks to foundation grants and industry money. Every day, pieces of information add to this exciting wing of microbiology: Some studies will come up short while others will show great promise for a particular strain of bacteria in a very specific disease. All the research, all the time--that's what you'll find in this section.
Autism Links to Microbes
Gut: brain connections are leading researchers to uncover the impact of microbial populations on brain function. The involvement of gut microbes in autism spectrum disorders is evident but specific data is conflicting. This chapter in "Diet-microbe interactions in the gut: effects on human health and disease" from Elsevier gives an overview of the research in this fascinating exploration.

Probiotics for Cats?
Lower urinary tract signs (LUTS) in cats are due to a combination of genetics, stress,environment, and medical conditions.
Healthy bacteria play a role in preventing LUTS. Other impacts are directly on water balance and nutrient metabolism and indirectly on gut health and immunity.Much of the evidence has been extrapolated from the role of microbes in humans. Read more here in the Journal of Animal Science.

Mushroom Wastes as Prebiotics
Researchers in Taiwan showed that polysaccharides from several different varieties of mushrooms could “enhance the survival rate of Lactobacillus acidophilus, Lactobacillus casei, and Bifidobacterium longum ... during cold storage. The polysaccharides had synergistic effects with the peptides and amino acids from a yogurt culture to maintain probiotics above 10(7) CFU/mL during cold storage, and they also had significant protective effects on these probiotics in simulated gastric and bile juice conditions to achieve beneficial effects in the host.”
The research was reported here in in the Journal of Food Science.

Probiotics in Gestational Diabetes?
Gestational diabetes is a rising concern when obesity—a risk factor-- is more prevalent in the child-bearing population. Previous studies in healthy pregnant women showed probiotic usage to benefit blood sugar control. A new study however found no benefit in obese women who were given a dose of Lactobacillus salivarius daily. There was no difference in fasting glucose levels, birth weight or incidence of gestational diabetes between the probiotic and placebo group.

Bacteriocins to the Rescue
Fermented foods produce fatty acids and hydrogen peroxide which bacteria use to defend their turf. They also produce bacterocins which are peptides that are powerful tools against invaders.
Bacterocins may eventually be used to prevent contamination in foods.
An excellent report is available free of charge from Shih-Chun Yang and colleagues who reviewed the latest knowledge and reports about bacteriocins.

Treating Ulcers with Probiotics Helps
Eliminating H. pylori is the answer to treating gastroduodenal ulcers. Unfortunately total eradication is difficult. Researchers in Kazakhstan asked of probiotics could assist. They treated 40 patients with probiotics and found an increase in H.pylori eradication rates as well as early relief of pain and dyspeptic symptoms. Also observed was recovery of intestinal microflora and less antibiotic-associated diarrhea. Read the study here in The Journal of the Federation of American Societies for Experimental Biology.
