For us, the bad bacteria are the ones that ferment any lactose that reaches them. The fermentation process releases gas, just like it does when beer is made. And you probably know all too well what the gas can do.
You can change the "bad" bacteria into "good" bacteria, the type that digests lactose rather than ferments it by using probiotics. Probiotics, literally "for life" contain the good bacteria and the idea is that the good bacteria will dominate the bad ones. I've written many times before about probiotics. The live and active cultures in yogurt are probiotics. You can also buy the bacteria in pill form in such products as Digestive Advantage and Lactagen.
What are prebiotics? Wesley Canfield of the Grand Forks Human Nutrition Research Center talks about them in his column.
Prebiotics ("before life") are nondigestible or fiber components of foods, usually complex carbohydrates that beneficially affect the host by stimulating the growth of intestinal bacteria. Certain bacteria prefer a particular prebiotic to use as a source of energy.
There are some potentially major advantages to eating more prebiotics, he says.
In addition to making vitamins, intestinal bacteria also produce other nutrients of benefit. We've all heard advice about limiting our intake of fats, especially saturated ones. However, not all saturated fats are bad for us. Many of the gut bacteria ferment digestion-resistant fiber to short-chain saturated fatty acids. These fats have two to four carbon atoms.
Acetate, propionate and butyrate all are examples of SCFA. Some scientists estimate that up to 10 percent of a person's daily energy needs can be met by using the SCFA as fuel. Butyrate, in particular, has been shown to have anti-cancer effects in animals. In addition, a probiotic containing butyrate-producing bacteria also reduced cancer formation in an animal model.
Another way of increasing butyrate production by intestinal bacteria is to eat prebiotics similar to the high-galactose type found in breast milk. Inulin, for example, is a type of high-fructose, nondigestible fiber that is present in wheat and onions. Many studies in both humans and animals have demonstrated the bifidobacteria-promoting benefits of inulin and other high-fructose prebiotics.
Prebiotics and probiotics. All part of a good healthy diet. Eat enough of them and hopefully you won't have to take any antibiotics.
Probiotics deliver positive results in nearly all cases of allergies. They can reduce the severity of hives, hay fever, asthma and food allergies.
