“…Kefir natural microbiota are lactic acid bacteria, yeasts and Acetobacter, the most abundant being the microorganisms of the genus Lactobacillus. The composition of this microbiota is different depending on the geographical region, but the interactions among kefir microorganisms from different locations and their functions are very similar [84].…”

“…Nevertheless, this effect on immunity has not been able to be demonstrated through experimental studies using laboratory animals fed with Kefir. Besides, the gut colonization capability of Kefir microbiota has not been determined [84].…”

“…Cardioprotective effects of fermented milk peptides have been mainly studied in laboratory animals, with the oral administration of isolated compounds [88]. Kefir has a wide range of probiotic health effects based on the metabolites produced by microbial cultures, which includes hypoglycemic, anticancer, anti-inflammatory and antibacterial activities [84]. Milk calcium improves the HDL:LDL cholesterol ratio, and caseins and whey proteins could also regulate blood pressure.…”

The term ‘superfoods’, used frequently with marketing purposes, is usually associated with foodstuffs with beneficial health properties. ‘Superfoods’ appears in many information sources, including digital media. The information they provide is easily accessible for consumers through Internet search engines. The objective of this work is to investigate the data that web pages offer to consumers and their accuracy according to current scientific knowledge. The two main search engines were utilized for English language websites search, introducing the term ‘superfoods’. In total, 124 search results were found. After applying the selection criteria, 45 web pages were studied. A total of 136 foods were considered as ‘superfoods’ by sites; 10 of them (kale, spinach, salmon, blueberries, avocado, chia, walnuts, beans, fermented milks and garlic) were mentioned on at least 15 sites. Nutritional and healthy properties displayed on sites were compared to scientific information. In conclusion, websites present the information in a very simplified manner and it is generally not wrong. However, they should offer to consumers comprehensible information without raising false expectations regarding health benefits. In any case, ‘superfoods’ consumption can have salutary effects as part of a balanced diet.

“…The microbial diversity of kefir has been thoroughly studied using culture- Kefir microbiota and its metabolites have been known to confer health benefits and gut immunomodulatory effects by stimulating, regulating, and enhancing the gut intestinal microbiota and functions [7,8]. Many microorganisms isolated from kefir have desirable probiotic properties such as high resistance to the low pH and bile salts in the gastrointestinal tract; bile salt hydrolase activity; non-cytotoxicity; and high adhesion to Caco-2 cells [9].…”

“…Besides the milk, the microbial and nutritional composition of kefir are influenced by starter cultures/kefir grains, the kefir grain to milk ratio, the source of inoculum, additives such such as fruits and inulin, the duration and temperature of its fermentation, and its storage conditions (Figure 1) [5,6]. Kefir microbiota and its metabolites have been known to confer health benefits and gut immunomodulatory effects by stimulating, regulating, and enhancing the gut intestinal microbiota and functions [7,8]. Many microorganisms isolated from kefir have desirable probiotic properties such as high resistance to the low pH and bile salts in the gastrointestinal tract; bile salt hydrolase activity; non-cytotoxicity; and high adhesion to Caco-2 cells [9].…”

Microbial Communities in Home-Made and Commercial Kefir and Their Hypoglycemic Properties

Kefir is a popular traditional fermented dairy product in many countries. It has a complex and symbiotic culture made up of species of the genera Leuconostoc, Lactococcus, and Acetobacter, as well as Lactobacilluskefiranofaciens and Lentilactobacillus kefiri. Though kefir has been commercialized in some countries, people are still traditionally preparing kefir at the household level. Kefir is known to have many nutritious values, where its consistent microbiota has been identified as the main valuable components of the product. Type 2 diabetes mellitus (T2DM) is a common diet-related disease and has been one of the main concerns in the world’s growing population. Kefir has been shown to have promising activities in T2DM, mostly via hypoglycemic properties. This review aims to explain the microbial composition of commercial and home-made kefir and its possible effects on T2DM. Some studies on animal models and human clinical trials have been reviewed to validate the hypoglycemic properties of kefir. Based on animal and human studies, it has been shown that consumption of kefir reduces blood glucose, improves insulin signaling, controls oxidative stress, and decreases progression of diabetic nephropathy. Moreover, probiotic bacteria such as lactic-acid bacteria and Bifidobacterium spp. and their end-metabolites in turn directly or indirectly help in controlling many gut disorders, which are also the main biomarkers in the T2DM condition and its possible treatment.
