Lactose is a disaccharide found in milk and dairy products. Children and adults with lactose intolerance are unable to tolerate significant amounts of lactose because of an inadequate amount of the enzyme lactase. The condition occurs in three main types: primary, secondary, and primary adult-type hypolactasia. The use of milk in the diet of these individuals may lead to appearance of the irritable bowel syndrome. In persons with lactose intolerance symptoms include diarrhoea, dominated by abdominal colic, loud peristaltic sounds, increased flatulence and meteorism. A diagnosis of lactose intolerance can usually be made with a careful history, elimination of lactose from the diet, lactose tolerance test, hydrogen breath test and genetic testing. In the absence of appropriate tests in patients with suspected primary adult-type hypolactasia, diagnosis can be made as in patients with food allergy. Treatment is based on the restriction of lactose intake with the use of fermented milk products. However, especially for children, if milk and dairy products are eliminated from the diet, it is important to ensure D vitamin and calcium supplementation.

Objective: The study assessed milk consumption and prevalence of lactose intolerance among self-perceived lactose intolerant students of Abia State Polytechnic, Aba. Subject and Methods: The study involved 121 self-reported lactose intolerants students from which 76 students with confirmed cases of lactose intolerant were selected from two purposively selected departments namely: Food Science and Technology (F.S.T) and Hospitality Management Technology (H.M.T) Abia State Polytechnic Aba. Questionnaires were used to collect information on dairy consumption and self- perceived intolerance to milk; while milk tolerance test was used to investigate the incidence of lactose tolerance among the student Results: The result shows that self-perceived lactose intolerance was higher (89%) than the estimated prevalence of (79%) among the students. The majority of the students consumed milk and dairy products, with percentages of 100%, 82%, 72%, and 100% for milk, ice cream, yoghurt, and flavored dairy products, respectively. The frequency and serving portions consumed per day were small. The percentages were 24%, 17%, 16%, and 15% for milk, ice cream, yoghurt, and flavored dairy products, respectively. None of the subjects consumed up to 2 serving of milk per day. Conclusion: The result shows that a high percentage of the students still consume milk and dairy products, irrespective of their lactose intolerance. This suggests that lactose intolerance could not stop the subjects from consuming milk and dairy products. The low frequency of daily consumers of milk and dairy products coupled with small portion sizes of milk and dairy products indicates that dairy consumption among the subjects was poor and inappropriate. Inappropriate consumption of milk and dairy products would fail to meet the nutritional needs of the consumer.

The growing global interest in functional foods containing nutrients capable of adding possible beneficial health effects is rapidly increasing both interest and consumer demand. In particular, functionalized beverages for their potential positive effect on health e.g., decreasing cholesterol level, lowering sugar, high fiber content, ability to enhance the immune system, and help digestion, have recently received special attention. Among the different beverages available on the market, probiotic dairy and non-dairy products have attracted much attention because of their affordable cost and their numerous therapeutic activities. Fermented milk and yogurt are currently worth €46 billion, with 77% of the market reported in Europe, North America, and Asia. Consumption of dairy beverages has some limitations due for example to lactose intolerance and allergy to milk proteins, thereby leading consumers to use non-dairy beverages such as fruit, grains, and vegetable juices to add probiotics to diet as well as driving the manufacturers to food matrices-based beverages containing probiotic cultures. The purpose of this review article is to evaluate the therapeutic performance and properties of dairy and non-dairy beverages in terms of probiotic, prebiotic, and synbiotic activities.

Young Finns Study

Individuals suffering from ATH (adult-type hypolactasia), defined by the LCT (gene encoding lactase-phlorizin hydrolase) C/C−13910 genotype (rs4988235), use less milk and dairy products and may have higher plasma HDL (high-density lipoprotein) and lower triacylglycerol (triglyceride) concentrations than their counterparts without ATH. To investigate the effects of ATH status on the early markers of atherosclerosis, we examined its association with CIMT (carotid intima-media thickness), CAC (carotid artery compliance) and brachial artery FMD (flow-mediated dilation) in a young population-based cohort of otherwise healthy individuals. As part of the Cardiovascular Risk in Young Finns Study, we performed CIMT, CAC and FMD analyses, LCT C/T−13910 genotyping and risk factor determination in 2109 young subjects 24–39 years of age (45% males) at the time of the examination. The consumption of both milk and dairy products was lowest and the consumption of alcohol highest in subjects with the C/C−13910 genotype (P<0.001 for all) in comparison with subjects without ATH (TT+CT). In multivariate analysis, no significant association between ATH status and CIMT, CAC or brachial artery FMD was found after adjustment for the use of alcohol, dairy products and all other major risk factors of coronary artery disease. In otherwise similar statistical analysis, the results remained non-significant when females and males were analysed in their own groups. In conclusion, the finding does not support the involvement of ATH in the pathogenesis of early atherosclerosis.

Milk is an emulsion containing fat, protein, carbohydrate, vitamins, minerals and water. Lactose is the main carbohydrate presented in milk and dairy products. This sugar is composed by one unit of glucose and one of galactose. Metabolism of lactose depends on enzyme lactase which hydrolyzes this sugar. In some cases, lactase may be absent or an insufficient quantity in human body. Deficiency in lactase production causes numerous symptoms such as diarrhea; abdominal pain and bloating that characterize lactose intolerance. The aim of this work was to evaluate concentration of lactose in milk and dairy products to determine the effect of the processing and to calculate the quantity of each product which can be consumed without symptoms in lactose intolerant. Results obtained show lactose concentration of 4.42% w/v in Milk; 3.5% w/w in Minas cheese; 9.9%w/v in condensed milk and 4.76%w/v in yogurt. Portion innocous ranged from 60 to 170 mL depending on each product.

The dairy industry is one of the important components of the food industry in Ukraine. Significant dynamic and structural changes in the procurement, processing and foreign trade of milk and dairy products have been observed in recent years. Further prospects for the development of the dairy industry are formed under the influence of a decrease in agricultural harvesting of milk, a decrease in the volume of deep processing of milk (production of butter and cheese), changes in foreign trade. It is important to study the current state of the dairy industry and identify trends in its further development. The tendencies of milk procurement by agricultural enterprises and households of Ukraine are investigated. Over the years milk production in agriculture has been dynamically diminishing, with a shift to entrepreneurial forms of dairy farming. It has been noted that the decrease in milk production volume in recent years has influenced the dynamics of industrial production of dairy products. In particular, in recent years the production of cheese and butter has decreased significantly, and milk production has been characterized by unstable trends. The general characteristics of Ukraine's foreign trade in milk and dairy products are presented. In recent years, the value of the export-to-import ratio has been positive for most dairy products. Over the last year (2018), exports of butter, condensed milk and cream, condensed milk and cream and whey prevailed in Ukraine. At the same time, they imported more cheese and butter, fermented or fermented milk and cream. The main part of the exported dairy products was export of butter and milk and cream condensed, imported mainly cheese. It is established that the main problem of the dairy industry today is the low level of milk production. Therefore, financial and investment processes should be stimulated to build farms and increase livestock production at enterprises to offset losses from reduced milk production by households. At the same time, it is necessary to encourage deep processing of milk, in particular the production of butter (main export product) and cheese (to avoid import dependence).

Human Health Effects

: Lactose is a reducing sugar consisting of galactose and glucose, linked by a β (1→4) glycosidic bond, considered as an antioxidant due to its α-hydroxycarbonyl group. Lactose is widely ingested through the milk and other unfermented dairy products and is considered to be one of the primary foods. On the other hand, lactose is also considered as one of the most widely used excipients for the development of pharmaceutical formulations. In this sense, lactose has been related to numerous drug-excipient or drug-food pharmacokinetic interactions. : Intolerance, maldigestion and malabsorption of carbohydrates are common disorders in clinical practice, with lactose-intolerance being the most frequently diagnosed, afflicting 10% of the world’s population. Four clinical subtypes of lactose intolerance may be distinguished, namely lactase deficiency in premature infants, congenital lactase deficiency, adult-type hypolactasia and secondary lactase intolerance. An overview of the main uses of lactose in human nutrition and in the pharmaceutical industry and the problems derived from this circumstance are described in this review.

Probiotic products available in the markets today, are usually in the form of fermented milk products. Dairy consumption have been limited by lactose intolerance and the cholesterol content in dairy products. Besides, traditions and economic reasons that limit the use of dairy fermented products in some developing countries promote the idea of using of alternative raw materials as vehicles for the probiotic agents. For these reasons meat products, cereals, legumes, fruits and vegetables may be potential substrates, where the healthy probiotic bacteria will make their mark, amongst consumers. To develop of these products is a key research priority for food design and a challenge for both industry and science sectors. In this study, information’s were given about non-dairy probiotic foods and highlighting the researches done in this field.

ABSTRACTGlobally, ∼70% of adults are deficient in intestinal lactase, the enzyme required for the digestion of lactose. In these individuals, the consumption of lactose-containing milk and dairy products can lead to the development of various gastrointestinal (GI) symptoms. The primary solution to lactose intolerance is withdrawing lactose from the diet either by eliminating dairy products altogether or substituting lactose-free alternatives. However, studies have shown that certain individuals erroneously attribute their GI symptoms to lactose and thus prefer to consume lactose-free products. This has raised the question whether consuming lactose-free products reduces an individual's ability to absorb dietary lactose and if lactose-absorbers should thus avoid these products. This review summarizes the current knowledge regarding the acclimatization of lactose processing in humans. Human studies that have attempted to induce intestinal lactase expression with different lactose feeding protocols have consistently shown lack of enzyme induction. Similarly, withdrawing lactose from the diet does not reduce intestinal lactase expression. Evidence from cross-sectional studies shows that milk or dairy consumption is a poor indicator of lactase status, corroborating the results of intervention studies. However, in lactase-deficient individuals, lactose feeding supports the growth of lactose-digesting bacteria in the colon, which enhances colonic lactose processing and possibly results in the reduction of intolerance symptoms. This process is referred to as colonic adaptation. In conclusion, endogenous lactase expression does not depend on the presence of dietary lactose, but in susceptible individuals, dietary lactose might improve intolerance symptoms via colonic adaptation. For these individuals, lactose withdrawal results in the loss of colonic adaptation, which might lower the threshold for intolerance symptoms if lactose is reintroduced into the diet.
