Probiotics are digestive bacteria which are naturally present in the gastric environment. This type of bacteria is necessary for the proper digestion of food as well as absorption of nutrients. Clinical studies have shown that the digestive tract must contain at least 10 to 15 % good bacteria to have a healthy digestion. In addition, trace amount of bad bacteria is also present inside the digestive tract. This is also important for digestion because these bacteria produce essential enzymes that aid digestion and absorption.
The most popular probiotics is called Lactobacillus acidophilus. This kind of bacteria produces lactic acid inside the stomach when they reproduce. Lactic acid increases the acidity of the gastric environment thus enhancing digestion. The acidity of the digestive tract also helps protect the stomach and intestines from overgrowth of harmful microorganisms such as yeasts, spores, molds and bacteria such as Escherichia coli and Salmonella.
The population of good bacteria in the digestive tract is depleted when the individual is on antibiotic therapy or under prolonged stress. Antibiotics are non – selective. This means that they do not only kill the harmful microorganisms but also the good ones. Good thing probiotics can be obtained from the diet such as yogurt, buttermilk, kefir and other fermented products. In addition, probiotics can also be provided by supplements. Therefore, when the person is to have an antibiotic therapy, the physician usually prescribes probiotic supplement to replenish the digestive tract with the killed good bacteria.
Moreover, if probiotics are prescribed, another form of supplement may also be recommended to aid the activity of probiotic supplements. These are called prebiotics which are considered to be fibers, either soluble or insoluble. These prebiotics does not increase the number of good bacteria in the digestive tract. Prebiotics serve as food for good bacteria thus making them healthy and strong against bad bacteria. Sources of prebiotics include fruits, vegetables, legumes and grains.
Other health benefits of probiotics are that it can enhance the health of the immune system and boost the intestinal barrier function. Probiotics also lessen the development of allergies to food and drugs. For lactose – intolerant individuals, yogurts with live and active cultures of lactobacillus acidophilus are recommended to relieve its disturbing symptoms. In addition, probiotics also has an anti – diarrheal property and at the same time helps in the regulation of normal bowel movement.
A good probiotic supplement must have at least ten million live bacteria. Experts also stressed that the good bacteria contained in a supplement must be that of the Lactobacillus strains. This family of bacteria is the only considered group of good bacteria which is strong enough to reach the intestines, bypassing the acidic environment of the stomach. Another helpful tip on what a good probiotic supplement must be is that the product must be guaranteed organic. Organic probiotics ensure that the bacteria are in its natural and live state and have not been destroyed with heat and strong chemicals during processes. Experts also suggest that you must choose those probiotic supplements in which the source is from organic vegetables.
