Lactobacilli: All You Need To Know About Bacteria?

Few people are aware of this, but bacteria within the human body are not always signs of disease. It is noteworthy that in each person's gut there are billions of microorganisms of different species and pathogens (causative or specific microorganisms that cause disease), forming the so-called intestinal flora.

? In healthy individuals, there is a balance between healthy and potentially harmful microorganisms, but this balance can be affected by external factors such as poor diet and antibiotic use ,? explains Daniela de Almeida, functional and sports nutritionist.

Such an imbalance not only hinders digestion but also makes the digestive tract vulnerable to attack by harmful microorganisms. Is it from there that the importance of such lactobacilli stands out? that almost everyone has heard of, but often without understanding its real meaning.


Daniela de Almeida explains that lactobacilli are microorganisms that reach the gastrointestinal tract and recompose the gut microbiota, inhibiting the colonization of pathogenic bacteria, and returning their balance.

For this reason, they are called probiotics ("beneficial bacteria").

Lactobacilli Health Benefits

Nutritionist Daniela de Almeida cites below the benefits offered by lactobacilli:


  • Restore the balance of the gut microbiota;
  • Improve constipation ("constipation");
  • Improve digestion by helping in the production of proteolytic and lipolytic enzymes;
  • Recover the integrity of the bowel wall in the case of inflammatory bowel disease;
  • Have anticancer effect;
  • Reduce diarrheal outbreaks by fighting pathogens;
  • Increase immunity;
  • They improve food allergy by preventing the translocation (moving from one location to another) of pathogens.

Where are lactobacilli found?

Daniela de Almeida points out that in healthy individuals there is a balance between healthy and potentially harmful microorganisms, but this balance can be affected by external factors. • Inadequate diet, indiscriminate use of medication, stress and physical inactivity can cause dysbiosis. term used for this imbalance of intestinal microorganisms ?, highlights.

And this is where another major advantage of lactobacilli stands out: can bacteria of this genus be ingested and still come alive in the gut, smoothly crossing the stomach? acidic environment where most microorganisms do not survive. That is, it is then possible to eat foods containing live lactobacilli.

It is worth mentioning that lactobacilli can be found in pure milk, which has just come from the cow, but not in pasteurized milk (which we find for sale in the market).


Thus, the marketed products containing live lactobacilli are yogurts and so-called probiotics (especially intended to help the digestive system with the introduction of microorganisms).

Dietitian Daniela explains that there is no recommended daily intake for lactobacilli foods. Is it believed that one yogurt a day, coupled with healthy eating? high in fiber and low in saturated fat and refined carbohydrates? and the practice of regular exercise is enough to maintain a healthy bowel?

Indications: Symptoms that some intestinal flora imbalance already exists

Daniela Almeida cites some symptoms that may indicate that there is already an imbalance in the intestinal flora:

  • Swelling
  • Intoxicated organism
  • Many gases
  • Constipation
  • Diarrhea Episodes
  • Candidiasis
  • Lactose intolerance
  • Irritable bowel syndrome
  • Chron's disease
  • Low immunity
  • Chronic fatigue
  • Vitamin and mineral malabsorption
  • Discouragement
  • Depression

"In these cases, supplementation may be indicated," says the nutritionist.

Lactobacillus contraindications

Should everyone eat lactobacilli foods or are there contraindications? This is a very common doubt.

Daniela de Almeida points out that people with milk allergies should avoid yogurts. "Already those who have lactose intolerance, should use those that do not contain lactose, products called lacfree," he says.

"Lactobacilli may also be used in the form of sachets or capsules, in association with other" good "bacteria, such as bifidobacteria, which improve intestinal function and the absorption of calcium, magnesium and iron, in addition to being effective against cystitis ?, explains the professional.

But, it is noteworthy, it is not necessary to go around today, looking for sachets or capsules of lactobacilli. Supplementation should be indicated, if necessary, by a professional (physician or nutritionist).

The most important thing is to follow a good diet (high in fiber and low in saturated fat and refined carbohydrates) daily associated with exercise and always be mindful of your health? And, in case of any different symptoms, consult a doctor you trust.
