In recent times, the consumption of kefir in Spain as one of the main alternatives to yogurt but the truth is that this fermented milk drink It has been a popular food for centuries in Eastern Europe, and especially in the Caucasus area, where it comes from. Part of its growing success is due to the health benefits attributed to kefir due to the variety of probiotics it contains.
Indeed, the positive effects of this product, which is usually made primarily with cow’s milk but can also be made from water (and thus be an ideal product for vegans or vegetarians), have given it a good reputation. Are bacteria that benefit the intestinal microbiota are, in fact, more present in kefir than in its ‘rival’ yogurt. Furthermore, when it has dairy content, kefir provides a boost of protein, calcium, magnesium, phosphorus, zinc, vitamin A or B12.
Thus, its consumption has historically been linked to combating salmonella or ulcer problems and is known to help calcium absorption and some studies have linked it to the reduction of asthma and allergy problems as well as cancer cells.

Thus, as researchers from Baltimore confirmed in a study published in the journal ‘Medicine’ a few years ago, they warned that, despite its positive effects, its excessive intake could lead to discomfort, especially among people with the sensitive digestive system which could cause bloating and flatulence, nausea or constipation.

The Spanish Nutrition Foundation recommends, in fact, eating daily between two and four servings of milk or its derivatives: not all of them being kefir is the most beneficial because excessive consumption can lead to gastrointestinal problems and cause diarrhea, abdominal bloating or vomiting.
The researchers also commented after their research that people with immunodeficiency diseases, such as lupus, rheumatoid arthritis or AIDS, or those who take medications to reduce the action of the immune system, should take kefir with caution. In addition, those who often suffer from yeast infections, such as candidiasis, should limit the consumption of this drink because in some cases it has been detected that probiotics may not help fight their pathogens.
