Such products as yogurt play a potential role in decreasing intestinal disorders and chronic diseases. According to a recent study, several non-nutrient components in yogurt such as sphingolipids, conjugated linoleic acid and butyric acid may play a role as anti-cancer agents [13]. The positive effect of probiotics on food allergies in children is another promising area of study. Recent studies in infants have revealed that probiotics not only alter the response to potentially harmful antigens (substances that induce allergies), but also reduce their allergenic potential [14]. Fermented dairy products are a good instance of functional foods. Many scientific studies confirm yogurt and other fermented diary products’ functional role which are increasingly advancing the immune system and preventing diseases. Fermented dairy products are good, and in some cases excellent, sources of nutrients namely calcium, protein and potassium [15].
