With the arrival of the cold months, our body faces important challenges such as temperature changes, changes in diet and greater exposure to viruses and bacteria that put the immune system under pressure. It is no coincidence that in autumn and winter the search for probiotics and fermented foods such as kefir increases exponentially. But what exactly are they and why do they become so important when temperatures drop?
What are probiotics and why are they essential
Probiotics are live microorganisms, mainly “good” bacteria and beneficial yeasts, which colonize our intestine, contributing to the balance of the bacterial flora. Among the best known are lactobacilli and bifidobacteria, naturally present in a healthy intestine. When we talk about probiotics, we are referring to a real defense team that works to maintain the well-being of our digestive system and, consequently, of the entire organism.
The gut, often called our “second brain,” houses about 70% of the immune system. A balanced gut microbiota not only promotes proper digestion, but also protects against infections, supports nutrient absorption and even influences our mood and energy levels.
Kefir: the natural probiotic par excellence
Among fermented foods rich in probiotics, kefir stands out as one of the most complete and beneficial. This fermented drink, similar to yogurt but with a more liquid consistency, contains an extraordinary variety of beneficial microorganisms: lactobacilli, bifidobacteria and probiotic yeasts that work synergistically.
Kefir is obtained from the fermentation of milk (or vegetable drinks) through “kefir grains”, a symbiotic combination of bacteria and yeasts. The result is a slightly fizzy drink, with a tart and refreshing taste, which provides billions of live probiotics in each serving. Unlike traditional yogurt, kefir contains a much wider range of bacterial strains and has a greater ability to colonize the intestine.
Why probiotics are essential in autumn and winter
During the cold months, our body is subjected to particular stress which can compromise the balance of the intestinal microbiota. The cold temperatures, the dry air of heated environments and less exposure to sunlight create the ideal conditions for intestinal imbalances.
During this period, exposure to pathogenic viruses and bacteria also increases, resulting in greater use of antibiotics. These drugs, although essential for fighting bacterial infections, have the side effect of eliminating not only harmful bacteria but also beneficial ones, profoundly altering the balance of the intestinal flora. This is why supplementation with probiotics becomes even more important after antibiotic therapy.
Furthermore, the cold season often leads to a shift towards a diet richer in heavy foods, fats and sugars, to the detriment of fresh fruit and vegetables. This change can favor the proliferation of “bad” bacteria at the expense of beneficial ones, causing bloating, intestinal irregularities and a weakening of the immune defenses.
How to choose the right probiotics
Not all probiotics are the same. To be effective, a probiotic supplement must contain specific bacterial strains, supported by scientific studies, in adequate quantities. It is also essential that probiotics are protected by gastro-resistant capsules, capable of overcoming the acidic environment of the stomach and reaching the intestine alive, where they can colonize and carry out their beneficial action.
Storage is another important aspect to consider: the best performing probiotics are often stored in dark pharmaceutical glass bottles, which offers optimal protection from light and guarantees the viability of the microorganisms over time, even if there are different types of packaging on the market.
The variety of strains is also fundamental: formulations that combine lactobacilli, bifidobacteria, spore-forming bacilli and yeasts offer a more complete and synergistic action, working on different fronts for intestinal well-being.
But which ones to choose? We have selected for you some of the best probiotics for autumn and winter.
