Article Abstract

We developed a synbiotic yogurt using monk fruit extract as a sweetener and investigated the effects of feeding the yogurt to rats with type 2 diabetes induced by streptozotocin and a high-fat diet. The rats fed the synbiotic yogurt showed greater blood glucose regulation and a significant decrease in insulin resistance and glycosylated hemoglobin compared with rats fed yogurt sweetened with sucrose, and they showed a remarkable improvement in short-chain fatty acid levels and gut microbiota status. Liver and kidney damage was also ameliorated in the rats fed the synbiotic yogurt. Immunohistochemistry analysis showed that the synbiotic yogurt inhibited β-cell loss compared with the control yogurt. Consuming the synbiotic yogurt helped to restore the islets of Langerhans. Our results indicated that monk fruit extract may be a good alternative to sucrose for synbiotic yogurt products in people with type 2 diabetes to delay the progression of diabetes and associated complications.

Functional foods consumption, included the synbiotics, has garnered attention of the consumers because of their health's benefits, being lactic acid bacteria (LAB) the microorganisms most used for their manufacturing. Twelve potential probiotic LAB strains were evaluated for cholesterol removal, phenolic content, antioxidant properties, α-glucosidase inhibitory activity (anti-diabetic effect), and in vitro angiotensin-I-converting enzyme- (ACE) inhibitory activity (anti-hypertensive effect), together with the assimilatory capacity of different prebiotics such as inulin, lactulose, β-glucans, and fructooligosaccharides, to be used in the production of a synbiotic yogur. Their anti-inflammatory potential in Caco-2 cells was also assayed.

Functional dairy foods represent a rapidly growing category in the food industry, driven by enormous consumer demand for health promotion and disease prevention. The interplay between probiotics and prebiotics in these products has the potential to enhance their overall health supports. Probiotics, such as s and species, commonly found in fermented dairy foods like yogurt, fermented milk, and whey beverages, support gut health by improving the intestinal homeostasis, that aids digestion, nutrient absorption, and strengthen the immune functionality.
