Yoghurt is a unique fermented dairy product, consumed throughout the world and the trend ofconsumption is increasing due to its unique health benefits. Yoghurt mix is often supplemented with MSNF(milk solids-non-fat), it may contain as much as 5.7% unhydrolysed lactose. Lactose can be hydrolysed withan enzyme lactase. Deficiency of lactase in lactose-intolerant persons leads to gastrointestinal...

BACKGROUND The relationship of symptoms with objective measurements, as well as some of the mechanisms involved in lactose tolerance after yoghurt consumption, remain unclear. METHODS The trial had a double-blind design in which 22 lactose malabsorbers received 25 g daily lactose in fresh (living bacteria > 108 cfu/g) yoghurt or heated (< 102 cfu/g) yoghurt for 15 days, followed by a cross-ov...

OBJECTIVE The major aim of this trial was to evaluate the potential interaction of fresh or pasteurized yoghurt intake with lactose intolerance on calcium assimilation by means of the stable isotope 43Ca as a tracer. METHODS Forty volunteers (age: 32 +/- 7 years) participated in this parallel simple blind study (20 of them with moderate lactose intolerance). The protocol included the intake o...

Probiotics are live micro-organisms that when administered in adequate amounts confer a health benefit on the host. Consumption of yoghurt has been shown to induce measurable health benefits linked to the presence of live bacteria. A number of human studies have clearly demonstrated that yoghurt containing viable bacteria (Streptococcus thermophilus and Lactobacillus delbrueckii sp. bulgaricus)...

This trial was designed to assess the effect of live probiotic consumption on leucine assimilation from fresh and pasteurised yoghurt in volunteers with different lactose digestibility. Thirty-three volunteers (mean age 32, s.d. 7 years) participated in this parallel single-blind study (16 of them with moderate lactose intolerance). Breath samples were taken before and at 15 min intervals over ...

We previously described the effects of intake of dairy products on plasmid dissemination in the digestive tract of gnotobiotic mice associated with human faecal flora (HFF) and found that yoghurt, heat-treated yoghurt (HTY) and milk reduced population levels of transconjugants compared with findings in mice fed a standard mouse diet. In the case of lactose intake, transconjugants were not detec...

The objective of the present study was to assess the effect of consumption of a yoghurt-based drink enriched with 1-2 g plant sterols/d on serum lipids, transaminases, vitamins and hormone status in patients with primary moderate hypercholesterolaemia. Thirty patients were randomly assigned to one of two treatment groups: a low-fat low-lactose yoghurt-based drink enriched with 1 g plant sterol ...

A number of health benefits have been claimed for probiotic bacteria such as Lactobacillus acidophilus, Bifidobacterium spp., and L. casei. These benefits include antimutagenic effects, anticarcinogenic properties, improvement in lactose metabolism, reduction in serum cholesterol, and immune system stimulation. Because of the potential health benefits, these organisms are increasingly being inc...

The only carbohydrate in milk is lactose, a disaccharide, which is formed of a molecule of glucose and a molecule of galactose. Cow's milk contains about 5 % lactose and human milk about 6'5-7 %. Lactose is hydrolysed to its monosaccharides principally by a specific enzyme, lactase, which is a f-galactosidase. There are also two other enzymes with ,3-galactosidase activitv, lysosomal acid 3-gal...
