The comparative analysis and comprehension of the aforementioned data would set the context for the next generation of research in blood transfusion science, since the need for safer and more efficient transfusions remains. Keywords: red blood cell storage lesion, donor/recipient variation, transfusion outcome, clinical relevance, research opportunities. Nowadays, increasingly more studies focus on the impact of donor characteristics on red blood cell storage lesion profile and transfusion outcomes2. The rationale behind those donor-oriented studies was similar to that widely adopted in solid organ or bone marrow transplantation research3. In addition, factors apparently irrelevant to storage quality, such as serum uric acid, can also affect storage lesion metrics in blood units6. The realisation that distinct groups of donors demonstrate different degrees of storage lesion progression, or post-transfusion performance, offers the opportunity to design a blood logistics model for optimal selection of blood donors and donor-recipient matching. Further proteomic analyses that produce large amounts of data have demonstrated donor-associated, storage induced changes that can be attributed to intrinsic variation in specific oxidative markers9. Although seemingly opposed to the recently reported conclusions of the randomised clinical trials showing that the age of blood is not related to post-transfusion mortality and morbidity in those specific settings11, donor variation considerations stand side by side with those trials by appreciating time as only one among the many parameters that affect the quality of blood labile product. As a matter of fact, any study focused on donor properties has the ability to detect storage- and/or transfusion-associated differences between blood units of exactly the same age, although the evidence collected so far is insufficient to draw definite conclusions about the clinical relevance of those differences for any donor characteristics. Assessment of the relativity of time and of the cell-to-organism complexity of the biological systems would inevitably lead to the acknowledgement that donor variability stands hierarchically above the age of stored blood. After all, measuring storage time in M/mM of equivalent metabolites instead of days seems extremely interesting. Extracting this kind of information would not be possible at all without the development of omics technologies and their application to blood storage. In addition, contemporary advances in optical and non-optical highresolution technologies allow for the thorough study of extracellular vesicles generated in the bag in order to assess their possible clinical relevance17. Even after sorting the data using bioinformatics tools, the need to link storage lesion variables with transfusion performance remains vital. Thus, the introduction of in vitro models of transfusion has been proved very helpful for a first-line evaluation of the post-transfusion phenotype8,18. In a second step, transition to the in vivo state, by using animal models of transfusion, provides further insight into the correlation between storage quality and transfusion effects19 and, eventually, both types of models fuel extended clinical trials in humans. Bearing in mind that all of the abovementioned approaches for studying post-transfusion efficacy and effects have their own pros and cons, it would be really informative to combine them, focusing on what each of them can provide instead of what each of them may conceal based on their intrinsic limitations20. Therefore, future clinical trials designed on the basis of more reliable and upward tested/checked input (and output) parameters would help in clarifying current uncertainties and controversial issues. Advances in omics and small particle biology technologies might permit the establishment of a large donor-to-recipient data infrastructure to achieve a robust assessment of the clinical relevance of various blood donor characteristics. These cumulative databases, will contribute to address key research questions in blood banking and Transfusion Medicine, and inform blood policy decisions. The story of a dog chasing his own tail: the transfusion paradox Both assessment and interpretation of clinical trials are of high importance for the evolution of Transfusion Medicine services. Despite research opportunities offered by the strictly controlled system of a blood unit to biomedical sciences, donated blood and its components represent precious therapeutic substances of human origin that are limited by their very nature. Consequently, it makes sense that the primary outcome measured by almost all of the recent randomised clinical trials was the ultimate human good, namely survival22,23. On the other hand, owing to the numerous systemic factors implicated, the outcome of a specific transfusion is by default a highly complex, multifaceted phenomenon. Although in vivo studies aim to overcome the limitations of in vitro human models in evaluating post-transfusion effects, instead of this, they unintentionally feed and multiply the complexity of the findings and their interpretation. In other words, the combination of storage lesion variables (probably related to post-transfusion efficacy) with the infinite systemic factors of the recipient, results in an exponential output of possible conditions rather than a cumulative one. In that case, retrospective studies regarding the efficacy of transfusion or its adverse effects for distinct groups of recipients treated with standard practice or (as much as possible) "equal" blood units might be of great value. A set of sub-lethal lesions and defects are only evident under physiological or near-physiological levels of stress (osmotic, mechanical, biochemical, etc. These examples give only a glimpse of the complexity of transfusion-related research, pointing towards a more systemic approach to answer outstanding issues.

And we need to keep in mind, as aptly stated by Nieves and Lindsay (2007), "Bone is not just calcium, and calcium does not function in isolation". Calcium and/or vitamin D-deficient rickets have been reported in young children in 59 countries. Nutritional rickets may be caused by either vitamin D or calcium deficiency, or more often, by a variable combination of both. The final common 134 Milk and dairy products in human nutrition pathway in the pathogenesis may be an inability to meet the calcium needs of the growing skeleton, whether from vitamin D deficiency in the face of a good calcium intake, or from dietary calcium lack in the face of vitamin D sufficiency. In Africa and some parts of tropical Asia calcium deficiency is the major cause of rickets, typically occurring after weaning and often after the second year of life (Thacher et al. Tooth decay is an increasing problem in developing countries as diets change to include more sweet and processed foods (Liljemark and Bloomquist, 1996, cited in Aimutis, 2004). Since the late 1950s, milk was believed to have a protective effect on tooth enamel (Shaw, Ensfied and Wollman, 1959; Jenkins and Ferguson, 1966). Milk has been suggested to have a protective effect against sugar when consumed together (Bowen and Pearson, 2003, cited in Johansson and Lif Holgerson, 2011). The anticariogenic effect of dairy products has been attributed to constituents such as calcium, phosphate and casein (Aimutis, 2004). Bioactive components in milk may also reduce dental caries by changing the microbial population of dental plaque, i. Animal studies have demonstrated reductions in dental caries when soluble calcium and phosphate salts were added to foods (Bowen, 1971; Grenby and Bull, 1975; van der Hoeven, 1985). Epidemiologic studies have shown that children and adults with higher concentrations of calcium and phosphate in their dental plaque had a lower incidence of dental caries (Ashley and Wilson, 1977; Schamschula et al. When caseinophosphopeptides from milk react with calcium and phosphate at the tooth surface they produce colloidal amorphous calcium phosphate complexes which promote remineralization of enamel in humans (Aimutis, 2004). In an in vitro study, yoghurt containing casein phosphopeptides prevented demineralization of tooth enamel and enhanced its remineralization (Ferrazzano et al. A Swedish study found that children who never ate cheese or ate it only once in the five-day period recorded had an average of 1. A similar study in Japan suggested that high intake of yoghurt may reduce the prevalence of dental caries in children but showed no association between caries and milk or cheese consumption (Tanaka, Miyake and Sasaki, 2010). The exact mechanism by which certain dairy products are anticariogenic is still unclear, but the current evidence suggests that consumption of these milk products can protect against dental caries (Johansson and Lif Holgerson, 2011). However, certain dietary patterns are associated with a greater risk of obesity because of their high energy content. A study of the dietary patterns of 15 890 Mexican adults found that the patterns with the highest consumption of refined foods, sweets and animal products were associated with being overweight or obese (Flores et al. Sichieri (2002) reported that a "Western diet", which included butter, margarine and soda, was associated with an increased risk of obesity in adults living in Rio de Janeiro. The healthy diet also included some dairy products, suggesting that consumption of moderate quantities26 of yoghurt and kumis does not increase the risk of obesity (Dugee et al. Moderate consumption of dairy products and lean meats and poultry can also be an important part of recommended food-based dietary guidelines. Maintaining recommended dietary patterns, appropriate energy intake and adequate physical activity levels are critical to prevent unhealthy weight levels. Sample sizes and the type of dairy analysed vary and some studies do not control for energy restriction. If adjustments are not made for total energy intake, the energy from dairy food in excess of total daily energy requirement could confound the impact of dairy on obesity risk. Additionally, direct comparison of prevalence rates of overweight and obesity is difficult as different countries use different methodology, criteria and growth references in classifying overweight and obesity. Epidemiological studies on dairy and obesity can be broadly categorized as those that assess the positive effect of dairy on weight gain and those that examine the protective role of dairy (particularly calcium) against weight gain. Out of 19 studies, eight (three involving children and five involving adults) showed a protective association of dairy intake against weight gain, seven found no impact on weight, one reported a significant protective association among overweight men, one reported an increased risk of weight gain among children with a high milk intake, and two studies reported both an increased and decreased risk of weight gain, depending on the dairy food type. Low-fat products were not found to be any more beneficial to weight status than whole milk or full-fat products.

Policies, structures and strategies must evolve to meet consumer needs for improved food and nutrition security and environmental sustainability. They must incorporate evidence-based learning and be of sufficient duration and scale to effect lasting, beneficial change. That said, there is room for improvement, above all to emphasize nutrition benefits and issues. Such nutrition issues are listed below and are discussed in more detail in Chapters 7 and 9. To be inclusive for smallholders, they need to designed as progressive and motivate stakeholders to invest in more market-oriented and commercial dairy-enterprise activities. Nutrition decision-makers: At household level, nutrition decision-makers are almost always women. A balance must be struck between scale and duration to effect lasting and sustainable nutritional change. In addition, the generation of data from full-scale operations would be useful to objectively measure the nutritional impact of dairyindustry programmes. Its comparative advantages of cross-cutting technological expertise could be more effectively mobilized through additional core resources which could be accessed by member countries, the private sector and dairy-industry development and financing partners. Investments: Investment in dairying in developing and transition countries should be aimed at ensuring inclusion of smallholders and tailored to national 348 Milk and dairy products in human nutrition and regional specificities.

Prepared creams are the milk products obtained by subjecting cream, reconstituted cream and/or recombined cream to suitable treatments and processes to obtain the characteristic properties as specified below: Pre-packaged liquid cream is the fluid milk product obtained by preparing and packaging cream, reconstituted cream and/or recombined cream for direct consumption and/or for direct use as such. Whipping cream is the fluid cream, reconstituted cream and/or recombined cream that is intended for whipping. When cream is intended for use by the final consumer the cream should have been prepared in a way that facilitates the whipping process. Cream packed under pressure is the fluid cream, reconstituted cream and/or recombined cream that is packed with a propellant gas in a pressure-propulsion container and which becomes Whipped Cream when removed from that container. Whipped cream is the fluid cream, reconstituted cream and/or recombined cream into which air or inert gas has been incorporated without reversing the fat-in-skimmed milk emulsion. Fermented cream is the milk product obtained by fermentation of cream, reconstituted cream or recombined cream, by the action of suitable microorganisms, that results in reduction of pH with or without coagulation. Where the content of (a) specific micro-organism(s) is (are) indicated, directly or indirectly, in the labelling or otherwise indicated by content claims in connection with sale, these shall be present, viable, active and abundant in the product to the date of minimum durability. Acidified cream is the milk product obtained by acidifying cream, reconstituted cream and/or recombined cream by the action of acids and/or acidity regulators to achieve a reduction of pH with or without coagulation. Its main food use is in the preparation of whey cheese, whey drinks and fermented whey drinks. The main industrial uses are in the manufacture of lactose, whey paste and dried whey. Two types of whey exist: acid whey, obtained during the production of acid-coagulated cheeses such as cottage cheese, and sweet whey, from the manufacture of rennet-coagulated cheese. The composition of acid whey is defined as follows: lactose: reference content of 61 percent milk protein: minimum content 7 percent milk fat: reference content 2 percent water: maximum content 4. In each case, the whey may be pre-concentrated prior to the further concentration of whey or coagulation of the whey proteins. The process may also include the addition of milk, cream, or other raw materials of milk origin before or after concentration or coagulation. The ratio of whey protein to casein in the product obtained through the coagulation of whey shall be distinctly higher than that of milk. The product obtained through the coagulation of whey may either be ripened or unripened. Other products produced from whey include whey protein concentrate and whey protein isolate. Casein is obtained from skimmed milk by precipitation (curdling) with acids or rennet. Caseins are low in sulphur amino acids, which limits their biological value (Fox and McSweeney, 1998). Data on milk products from milk from underutilized species are less common in literature, and are outlined below. Reindeer milk Reindeer milk is important in the summer diet of herders, dried in curd form, or made into cheese, butter and sour cream. Yak milk Mongolian people use yak milk to produce a range of food products, including the fermented milk products kurut (Section 3. The other, consisting of protein and fat, is called "white butter" and is used as food during the winter in mixtures with sugar and other products (Indra and Magash, 2002). Camel milk Although most camel milk is consumed raw or in the form of fermented milk, commercial farms supply fresh pasteurized milk in Saudi Arabia (Mehaia et al. Bactrian camel milk is used for making cheese, butter and yoghurt in Mongolia (Jirimutu et al. Studies on dromedary camel milk report that camel milk is less favourable for cheese-making than cow, sheep and goat milk because it does not produce a curd but rather produces flakes that lack firmness (Mehaia, 1997; Bornaz et al.
