Unlike antibiotics, which means “to destroy life,” probiotics literally means “life giving.” In more practical terms, antibiotics destroy without prejudice — killing the bad bacteria that can cause infection, while also destroying the good bacteria that help fight infection. Probiotics, on the other hand, re-populate the good bacteria that can help kill the bad bacteria and fight infection.
With the number of bacteria-resistant diseases on the rise and the length of time it takes to develop new antibiotics, it might be time to consider another alternative: Probiotics.
Antibiotics have been in use since 1939 when penicillin was isolated, followed by streptomycin five years later. Both of these powerful, “miracle” drugs were mass produced during World War II,1 and are credited with effectively treating bacterial illnesses and saving many lives. In fact, the likelihood of dying prematurely from infectious diseases in the early 19th century — before antibiotics — was as high as 40%.2
Since then, a diverse number of antibiotics have been produced. Most are medium- and broad-spectrum antibiotics which, instead of killing the offending bacteria, kill ALL bacteria. These include tetracyclines, ciprofloxacin, bacitracin, erythromycins, penicillin, cephalosporins, and streptomycins.
One of the side effects of medium- and, especially, broad-spectrum antibiotics is that they radically change the bacterial population in the intestines. Because these antibiotics kill all bacteria — even good bacteria that fight infectious bad bacteria — they put the body at risk for superinfection by fungi and other microorganisms.1
Treating a superinfection with more antibiotics then creates a vicious cycle: more antibiotics are administered, the immune system breaks down, the depleted body surrenders to yet another superbug which requires even more antibiotics.
Clearly, the “miracle” drug of the 1940s — which caused some to predict the end of infectious diseases by the 1960s — now appears to have entered a new “post-antibiotic era” where bacteria-resistant illnesses significantly outpace the development of new antibiotics to treat them.3
Just a few years after penicillin was put on the market, scientists began noticing a penicillin-resistant strain of Staphylococcus aureus — bacteria normally found in the body’s intestinal flora. Twenty-five years later, resistant strains of gonorrhea, shigella, and salmonella appeared.3
Since then, bacteria-resistant illnesses have become a worldwide public health concern. According to the Centers for Disease Control and Prevention (CDC), two million patients a year pick up infections in U.S. hospitals. About 90,000 die as a result. Of these deaths, approximately 70% are caused by bacteria that are resistant to at least one antibiotic.4
Not only that but vancomycin-resistant Enterococcus faecium (VRE) and methicillin-resistant Staphylococcus aureus (MRSA), once confined to hospitals, have begun creeping into the community at large.2
While poverty and counterfeit drugs contribute to bacteria-resistant illnesses in Third World countries, physicians over-prescribing antibiotics, lack of education among patients, and livestock feeding practices account for the majority of bacteria-resistance in the U.S.
By physicians. In the U.S., physicians write approximately one million prescriptions for antibiotics each year. Of these, says the CDC, half are inappropriately prescribed for common viruses — not the bacterial illnesses for which antibiotics were intended.5
Doctors cite time, uncertainty, and patient demand as reasons for over-prescribing antibiotics.5 In one study where 80% of prescriptions were not within the CDC guidelines, patients were significantly more likely to receive an unnecessary antibiotic when they indicated their illness was severe or where they mentioned a positive experience with a previous antibiotic.5
With most doctors seeing patients for a brief 15-20 minutes, their primary concern — and what their training has taught them — is to halt symptoms. If patients say that they’ve had a good experience with a particular antibiotic, physicians will often write a prescription for that antibiotic without delving into the cause of the symptoms.5
By patients. In the U.S., we do everything fast. And healing is no exception. Patients’ demand a label and a quick fix for whatever ails them — even if they don’t understand the consequences. As one study found, 58% of patients were not aware of the possible health risks associated with the misuse of antibiotics.5
In addition, drug companies spend $12 billion each year to advertise their drugs.6 Apparently, it’s working. Ninety-five percent of doctors had seen an average of seven patients in the previous six months who requested specific drugs that they’d seen advertised on TV, in newspapers or magazines, or on the Internet.2
Finally, patients have a tendency to stop taking antibiotics as soon as they feel better. Not taking the full course of prescribed antibiotics, however, allows the bacteria that should’ve been killed off to continue growing and mutating into a resistant strain.3
In our food. The Union of Concerned Scientists estimates that more than 70% of all antibiotics used in the U.S. each year — some 25 million pounds — are routinely fed to the poultry, pigs, and beef cattle that end up on our dinner plates. But it’s not to treat disease as you might suspect. Instead, antibiotics are used as food additives to promote faster growth and to compensate for illnesses the animals might get as a result of crowded and unsanitary conditions on corporate farms and in feedlots. And over half of these antibiotics are the same ones that doctors depend on to treat human illness!7
It’s no wonder, then, that we now see bacteria-resistant illnesses jumping species. According to the World Health Organization, vancomycin-resistant Enterococcus faecium (VRE) may be an example of a disease that first appeared in animals, then jumped to the more vulnerable segments of the human population.2
There are also implications for the U.S. meat trade. As reported by the General Accounting Office (GAO), New Zealand, Denmark, and the European Union — all competitors in the world meat market — have banned the use of most, if not all, antibiotics as growth promoters. And they have done this without adversely affecting food safety.2
All of these — doctors, patients, and our food — have negatively contributed to the increasing number of bacteria-resistant illnesses in the U.S. and around the world. While new antibiotics are continually being developed, the time it takes to get them to market can be as long as ten or more years. And by that time, they may not be effective against the bacteria-resistant illnesses they were intended to treat.
Clearly, the “post-antibiotic era” opens the door for new, more life-giving treatments for infectious diseases.
As mentioned above, antibiotics kill indiscriminately. They not only kill the bad bacteria that cause illness, they wipe out the good bacteria that fight off the illness-producing bad bugs. In fact, the word “antibiotics” means “to destroy life.”
Probiotics, on the other hand, “give life.” And re-populating the gut with healthy intestinal flora, such as high-dose probiotics, can often help those with chronic conditions feel better.
Allergies. At the University of Michigan, researchers mimicked the human antibiotic experience by injecting a broad-spectrum antibiotic into mice, and then re-populating their intestines with yeast to allow a yeast infection to take hold. When introduced to some common allergens, the mice without the antibiotic had much milder symptoms than did the mice with the antibiotic.8
Other studies have indicated that mice lacking healthy intestinal flora — such as those injected with a broad-spectrum antibiotic — cannot generate a tolerance for allergens while mice with a healthy gut flora tolerate allergens fairly well.8 Future studies are planned to consider the effect of re-populating the gut with probiotics.
The positive value of probiotics is undeniable. In a long-term study, those who ate one cup of non-pasteurized yogurt with live, active cultures every day were shown to significantly improve their health and immunity and especially to reduce allergy symptoms.9
Candidiasis. Candidiasis — also called Candida albicans or Candida — is a type of yeast that often overwhelms the body following the administration of broad-spectrum antibiotics. Though some healthcare professionals believe that Candidiasis only affects those with severely compromised immune systems (like those with HIV or cancer), more and more evidence is challenging that assumption — with estimates of actual incidence being surprisingly high — and pointing to antibiotics as the main culprit in recurring Candidiasis.10
As an example: one in 12 women suffers from recurring vaginal yeast infections — one of the more common symptoms of Candida. One study found that of the 50 women who received weekly probiotics applications for a year, none had a recurrence whereas about 200 infections would normally have been expected during that same time.10
Diarrhea. Perhaps the best evidence for the powerful effectiveness of probiotics is in the extensive research done with those who suffer from various forms of diarrhea: infectious diarrhea, antibiotic-associated diarrhea, chronic diarrhea, and traveler’s diarrhea.11
One particular study showed that infant formula supplemented with probiotics was far more effective at decreasing the risk of diarrhea, respiratory illnesses, and fever than for those infants taking a placebo formula.11
In another study, researchers found that hospital patients who drank a fermented milk containing probiotics every day had significantly fewer cases of antibiotic-associated diarrhea than those who drank a placebo. These patients also had a significantly shorter median hospital stay than the placebo patients.12
Eczema and other skin conditions. Evidence found that babies considered at high risk for allergies who were given probiotics for six months following their births, cut their incidence of eczema by 40%.13 Another study showed that allergy-prone mothers who took probiotics during pregnancy were less likely to have children suffering from eczema.14
Infections. Because probiotics help build up the immune system, it only makes sense that they also help fight infection. A seven-month study of more than 570 children in day care centers found that drinking a probiotic milk reduced the number and severity of respiratory infections — and the need for antibiotics.15
Inflammatory Bowel Disease, Ulcerative Colitis, and Crohn’s Disease. Researchers conducted a study of 327 patients with a history of ulcerative colitis. Some patients were treated with the prescription drug mesalamine while the others were treated with an uncommon and less studied probiotic strain. Findings indicate that the probiotic was just as effective as the drug.16
In another study, patients taking a high-dose probiotic following surgery for ulcerative colitis had a lower chance of relapse than those in the control group.14
The evidence for the effectiveness of probiotics continues to grow. According to Psychology Today, clinical trials continue to suggest that “increasing the gut’s level of probiotics prevents and alleviates many intestinal problems, from simple indigestion to diarrhea, flatulence, and bloating. It may also lower cholesterol and prevent tumor recurrence.”17
Clearly, using high-dose probiotics to re-populate the intestinal flora with healthy bacteria can have some powerful health benefits, especially for those who have had medium- or broad-spectrum antibiotic therapy in the past.
