TL;DR: In this paper, we realiseren ons onvoldoende dat we een product zijn van de natuur, en niet ons genoom per se, is de belangrijkste oorzaak van de huidige chronische (degeneratieve) ziekten.
Abstract: Darwin beschouwde de leefomstandigheden als de belangrijkste drijvende kracht achter de evolutie. Organismen voorzien de natuur van een grote genetische diversiteit en de natuur maakt hieruit een keuze. Ons genoom is gedurende de evolutie dus bij uitstek aangepast aan de omgeving, waaronder klimaat, voeding en pathogenen. Homo sapiens is ongeveer 160.000 jaar oud en ons genoom muteert met een snelheid van ongeveer 0,5% per miljoen jaar. Door de snelle verandering van onze omgeving in de afgelopen 100 jaar hebben we een conflict veroorzaakt tussen ons nog in het paleolithisch tijdperk (2,5*10 6 tot 10 4 jaar geleden) verkerend genoom en deze omgeving. Dit conflict, en niet ons genoom per se, is de belangrijkste oorzaak van de huidige chronische (degeneratieve) ziekten, waaronder diabetes mellitus, hart en vaatziekten, bepaalde vormen van kanker en enkele psychiatrische ziekten. Inzake de voeding begon dit conflict ongeveer 10.000 jaar geleden bij de overgang van ons bestaan als jager-verzamelaars naar een agrarische samenleving die gepaard ging met een hoge consumptie van koolhydraten. Het conflict is geescaleerd vanaf de industriele revolutie, en in een stroomversnelling geraakt vanaf het begin van de vorige eeuw, onder andere door een hoge inname van verzadigd vet en van mono- en disacchariden, een lage inname van vis en een ongunstige balans tussen energie inname en fysieke activiteit. We realiseren ons onvoldoende dat we een product zijn van de natuur. Nabootsing van de paleolithische leefomstandigheden naar moderne inzichten is van belang voor zowel primaire als secundaire preventie. Educatie vanaf de schoolleeftijd, (meer) aandacht voor voeding/leefstijl in de studies geneeskunde en farmacie, en een verplichte productinformatie die (veel) verder gaat dan de huidige summiere aanduidingen kunnen een gunstige rol spelen bij de beslechting van het conflict.

TL;DR: This review focuses on lifestyle changes, especially dietary habits, that are at the basis of chronic systemic low grade inflammation, insulin resistance and Western diseases, and the disturbance of the authors' inflammatory/anti-inflammatory balance is illustrated by dietary fatty acids and antioxidants.
Abstract: In this review, we focus on lifestyle changes, especially dietary habits, that are at the basis of chronic systemic low grade inflammation, insulin resistance and Western diseases. Our sensitivity to develop insulin resistance traces back to our rapid brain growth in the past 2.5 million years. An inflammatory reaction jeopardizes the high glucose needs of our brain, causing various adaptations, including insulin resistance, functional reallocation of energy-rich nutrients and changing serum lipoprotein composition. The latter aims at redistribution of lipids, modulation of the immune reaction, and active inhibition of reverse cholesterol transport for damage repair. With the advent of the agricultural and industrial revolutions, we have introduced numerous false inflammatory triggers in our lifestyle, driving us to a state of chronic systemic low grade inflammation that eventually leads to typically Western diseases via an evolutionary conserved interaction between our immune system and metabolism. The underlying triggers are an abnormal dietary composition and microbial flora, insufficient physical activity and sleep, chronic stress and environmental pollution. The disturbance of our inflammatory/anti-inflammatory balance is illustrated by dietary fatty acids and antioxidants. The current decrease in years without chronic disease is rather due to "nurture" than "nature," since less than 5% of the typically Western diseases are primary attributable to genetic factors. Resolution of the conflict between environment and our ancient genome might be the only effective manner for "healthy aging," and to achieve this we might have to return to the lifestyle of the Paleolithic era as translated to the 21st century culture.

TL;DR: A study of the effects of food supplements on aggression, rule-breaking, and psychopathology among young Dutch prisoners found the results to be promising, but no significant improvements were found in a number of other outcome measures.
Abstract: In an earlier study, improvement of dietary status with food supplements led to a reduction in antisocial behavior among prisoners. Based on these earlier findings, a study of the effects of food supplements on aggression, rule-breaking, and psychopathology was conducted among young Dutch prisoners. Two hundred and twenty-one young adult prisoners (mean age=21.0, range 18-25 years) received nutritional supplements containing vitamins, minerals, and essential fatty acids or placebos, over a period of 1-3 months. As in the earlier (British) study, reported incidents were significantly reduced (P=.017, one-tailed) in the active condition (n=115), as compared with placebo (n=106). Other assessments, however, revealed no significant reductions in aggressiveness or psychiatric symptoms. As the incidents reported concerned aggressive and rule-breaking behavior as observed by the prison staff, the results are considered to be promising. However, as no significant improvements were found in a number of other (self-reported) outcome measures, the results should be interpreted with caution.

TL;DR: The evidence for the long-reigning hypothesis of human evolution on the arid savanna is weighed against the hypothesis that man evolved in the proximity of water and the composition and merits of so-called 'Palaeolithic diets' are evaluated.
Abstract: Evolutionary medicine acknowledges that many chronic degenerative diseases result from conflicts between our rapidly changing environment, our dietary habits included, and our genome, which has remained virtually unchanged since the Palaeolithic era Reconstruction of the diet before the Agricultural and Industrial Revolutions is therefore indicated, but hampered by the ongoing debate on our ancestors' ecological niche Arguments and their counterarguments regarding evolutionary medicine are updated and the evidence for the long-reigning hypothesis of human evolution on the arid savanna is weighed against the hypothesis that man evolved in the proximity of water Evidence from various disciplines is discussed, including the study of palaeo-environments, comparative anatomy, biogeochemistry, archaeology, anthropology, (patho)physiology and epidemiology Although our ancestors had much lower life expectancies, the current evidence does neither support the misconception that during the Palaeolithic there were no elderly nor that they had poor health Rather than rejecting the possibility of 'healthy ageing', the default assumption should be that healthy ageing posed an evolutionary advantage for human survival There is ample evidence that our ancestors lived in a land-water ecosystem and extracted a substantial part of their diets from both terrestrial and aquatic resources Rather than rejecting this possibility by lack of evidence, the default assumption should be that hominins, living in coastal ecosystems with catchable aquatic resources, consumed these resources Finally, the composition and merits of so-called 'Palaeolithic diets', based on different hominin niche-reconstructions, are evaluated The benefits of these diets illustrate that it is time to incorporate this knowledge into dietary recommendations

TL;DR: It will be argued that, in order to disentangle some of the ambiguities involved, it has to broaden the temporal horizon of the debate, and clarify the concept of nature that emerged in the context of the “Common Human Pattern”.
Abstract: Debates on the role of biotechnology in food production are beset with notorious ambiguities. This already applies to the term “biotechnology” itself. Does it refer to the use and modification of living organisms in general, or rather to a specific set of technologies developed quite recently in the form of bioengineering and genetic modification? No less ambiguous are discussions concerning the question to what extent biotechnology must be regarded as “unnatural.” In this article it will be argued that, in order to disentangle some of the ambiguities involved, we have to broaden the temporal horizon of the debate. Ideas about biotechniques and naturalness have evolved in various socio-historical contexts and their historical origins will determine to a considerable extent their actual meaning and use in contemporary deliberations. For this purpose, a comprehensive timetable is developed, beginning with the Neolithic revolution ~10,000 years ago (resulting in the emergence of agriculture and the Common Human Pattern) up to the biotech revolution as it has evolved from the 1970s onwards—sometimes referred to as a second “Genesis.” The concept of nature that emerged in the context of the “Common Human Pattern” differs considerably from traditional philosophical concepts of nature (such as coined by Aristotle), as well as from the scientific view of nature conveyed by the contemporary life sciences. A clarification of these different historical backdrops will allow us to understand and elucidate the conceptual ambiguities that are at work in contemporary debates on biotechnology and the place of human beings in nature.

TL;DR: The role of genomics is explored with the help of two examples, namely the renaissance of Paleolithic diets and of Pleistocene parks, to argue that an understanding of the world in ecocentric terms requires new partnerships and mutually beneficial forms of collaboration and convergence between life sciences, social sciences, and the humanities.
Abstract: Views of ourselves in relationship to the rest of the biosphere are changing. Theocentric and anthropocentric perspectives are giving way to more ecocentric views on the history, present, and future of humankind. Novel sciences, such as genomics, have deepened and broadened our understanding of the process of anthropogenesis, the coming into being of humans. Genomics suggests that early human history must be regarded as a complex narrative of evolving ecosystems, in which human evolution both influenced and was influenced by the evolution of companion species. During the agricultural revolution, human beings designed small-scale artificial ecosystems or evolutionary "Arks," in which networks of plants, animals, and microorganisms coevolved. Currently, our attitude towards this process seems subject to a paradoxical reversal. The boundaries of the Ark have dramatically broadened, and genomics is not only being used to increase our understanding of our ecological past, but may also help us to conserve, reconstruct, or even revivify species and ecosystems to whose degradation or (near) extinction we have contributed. This article explores the role of genomics in the elaboration of a more ecocentric view of ourselves with the help of two examples, namely the renaissance of Paleolithic diets and of Pleistocene parks. It argues that an understanding of the world in ecocentric terms requires new partnerships and mutually beneficial forms of collaboration and convergence between life sciences, social sciences, and the humanities.

TL;DR: A fuller understanding of patterns of human plasticity in response to early nutrition and other environmental factors will have implications for the administration of public health.
Abstract: Many plants and animals are capable of developing in a variety of ways, forming characteristics that are well adapted to the environments in which they are likely to live. In adverse circumstances, for example, small size and slow metabolism can facilitate survival, whereas larger size and more rapid metabolism have advantages for reproductive success when resources are more abundant. Often these characteristics are induced in early life or are even set by cues to which their parents or grandparents were exposed. Individuals developmentally adapted to one environment may, however, be at risk when exposed to another when they are older. The biological evidence may be relevant to the understanding of human development and susceptibility to disease. As the nutritional state of many human mothers has improved around the world, the characteristics of their offspring--such as body size and metabolism--have also changed. Responsiveness to their mothers' condition before birth may generally prepare individuals so that they are best suited to the environment forecast by cues available in early life. Paradoxically, however, rapid improvements in nutrition and other environmental conditions may have damaging effects on the health of those people whose parents and grandparents lived in impoverished conditions. A fuller understanding of patterns of human plasticity in response to early nutrition and other environmental factors will have implications for the administration of public health.

TL;DR: The results showed that in French normal adults living in an urban environment with a lack of direct exposure to sunshine, diet failed to provide an adequate amount of vitamin D, and the clinical utility of winter supplementation with low doses ofitamin D was discussed.
Abstract: The vitamin D status of a general adult urban population was estimated between November and April in 1569 subjects selected from 20 French cities grouped in nine geographical regions (between latitude 43° and 51° N). Major differences in 25-hydroxyvitamin D (25(OH)D) concentration were found between regions, the lowest values being seen in the North and the greatest in the South, with a significant ‘sun’ effect (r = 0.72; p = 0.03) and latitude effect (r = -0.79; p = 0.01). In this healthy adult population, 14% of subjects exhibited 25(OH)D values ≤ 30 nmol/l (12 ng/ml), which represents the lower limit (< 2 SD) for a normal adult population measured in winter with the same method (RIA Incstar). A significant negative correlation was found between serum intact parathyroid hormone (iPTH) and serum 25(OH)D values (p < 0.01). Serum iPTH held a stable plateau level at 36 pg/ml as long as serum 25(OH)D values were higher than 78 nmol/l (31 ng/ml), but increased when the serum 25(OH)D value fell below this. When the 25(OH)D concentration became equal to or lower than 11.3 nmol/l (4.6 ng/ml), the PTH values reached the upper limit of normal values (55 pg/ml) found in vitamin D replete subjects. These results showed that in French normal adults living in an urban environment with a lack of direct exposure to sunshine, diet failed to provide an adequate amount of vitamin D. It is important to pay attention to this rather high prevalence of vitamin D insufficiency in the general adult population and to discuss the clinical utility of winter supplementation with low doses of vitamin D.

TL;DR: The global mtDNA diversity in humans is described based on analyses of the complete mtDNA sequence of 53 humans of diverse origins, providing a concurrent view on human evolution with respect to the age of modern humans.
Abstract: The analysis of mitochondrial DNA (mtDNA) has been a potent tool in our understanding of human evolution, owing to characteristics such as high copy number, apparent lack of recombination, high substitution rate and maternal mode of inheritance. However, almost all studies of human evolution based on mtDNA sequencing have been confined to the control region, which constitutes less than 7% of the mitochondrial genome. These studies are complicated by the extreme variation in substitution rate between sites, and the consequence of parallel mutations causing difficulties in the estimation of genetic distance and making phylogenetic inferences questionable. Most comprehensive studies of the human mitochondrial molecule have been carried out through restriction-fragment length polymorphism analysis, providing data that are ill suited to estimations of mutation rate and therefore the timing of evolutionary events. Here, to improve the information obtained from the mitochondrial molecule for studies of human evolution, we describe the global mtDNA diversity in humans based on analyses of the complete mtDNA sequence of 53 humans of diverse origins. Our mtDNA data, in comparison with those of a parallel study of the Xq13.3 region in the same individuals, provide a concurrent view on human evolution with respect to the age of modern humans.
