Good Bacteria to Prevent Disease

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.
