Good Bacteria to Prevent Disease

Gabe Mirkin, M.D.

 
When you eat, enzymes from your intestines, stomach, liver and 
pancreas break down carbohydrates into their building blocks called 
sugars; proteins into amino acids; and fats into glycerol, fatty 
acids and monoglycerides that can be absorbed into your bloodstream. 
However, many plant foods contain undigestible starches that cannot 
be broken down into sugars, so they cannot be absorbed in the upper 
intestinal tract. When they reach the colon, bacteria ferment these 
undigestible starches to form other chemicals including short chain 
fatty acids that protect your intestinal lining. from irritation and 
cancer, and are absorbed into your bloodstream to lower cholesterol 
and prevent heart attacks.

Humans have used these good bacteria, such a lactobacillus, to 
ferment and preserve milk and plant products . Recent research shows 
that normal intestinal bacteria are so numerous that they make up 
approximately 95 percent of the total number of cells in the human 
body. They help prevent bad bacteria from infecting you, and may 
help prevent intestinal diseases such as ulcerative colitis, Crohn's 
disease and cancer. Researchers have shown that two nondigestible 
carbohydrates, fructooligosaccharides and inulin, can help heal 
intestines swollen and damaged by diarrhea-causing bacteria. Several 
recent studies show that normal intestinal bacteria prevent cancers 
that would have been caused by such chemicals as the rat colon 
carcinogen, 1,2-dimethylhydrazine. Other studies show that these 
nondigestible carbohydrates increase absorption of the minerals, 
calcium, magnesium, zinc, and iron, and may treat and prevent 
osteoporosis in animals.
