    Differences in vitamin D status between countries in young adults and the elderly. McKenna MJ. Am J Med. 1992 Jul;93(1):69-77. PMID: 1385673 PURPOSE: To compare vitamin D status between countries in young adults and in the elderly. MATERIALS AND METHODS: Reports on vitamin D status (as assessed by serum 25-hydroxyvitamin D) from 1971 to 1990 were reviewed. Studies were grouped according to geographic regions: North America (including Canada and the United States); Scandinavia (including Denmark, Finland, Norway, and Sweden); and Central and Western Europe (including Belgium, France, Germany, Ireland, The Netherlands, Switzerland, and the United Kingdom). RESULTS: Vitamin D status varies with the season in young adults and in the elderly, and is lower during the winter in Europe than in both North America and Scandinavia. Oral vitamin D intake is lower in Europe than in both North America and Scandinavia. Hypovitaminosis D and related abnormalities in bone chemistry are most common in elderly residents in Europe but are reported in all elderly populations. CONCLUSIONS: The vitamin D status in young adults and the elderly varies widely with the country of residence. Adequate exposure to summer sunlight is the essential means to ample supply, but oral intake augmented by both fortification and supplementation is necessary to maintain baseline stores. All countries should adopt a fortification policy. It seems likely that the elderly would benefit additionally from a daily supplement of 10 micrograms of vitamin D.

    "Coronary Heart Disease Mortality and Blood Cholesterol In the Seven Countries study, there were great differences in coronary heart disease (CHD) mortality at similar blood cholesterol levels. In this study Dr. Keys pointed to a correlation between deaths from coronary heart disease and serum cholesterol in 15 populations in seven countries. Dr Ravnskov plotted his original data which was not available in the research summaries. Particularly interesting were differences between two localities within the same country or nearby islands in each of 4 of the seven countries. West Finland had about 45 CHD (coronary heart disease) deaths at a median cholesterol level of 250 mg/dl. However North Karelia, also in Finland, had over 200 CHD deaths at about 260 mg/dl. The island of Crete had only 20 CHD deaths at cholesterol levels of about 200. The nearby island of Corfu had about 85 CHD deaths at a cholesterol level of about 190 mg/dl."

Alpha-linolenic acid reduces risk of nonfatal MI - theheart.org - 0 views

    "July 9, 2008 | Michael O'Riordan Boston, MA - The consumption of a diet containing vegetable oils rich in alpha-linolenic acid (ALA) is associated with significant reductions in the risk of nonfatal MI, a new study has shown [1]. Investigators say the protective effect of ALA is evident among individuals with low intakes, suggesting the greatest benefit might be in developing countries, where fatty-acid consumption is limited. "The potential for benefit is great when the baseline intake is low," said lead investigator Dr Hannia Campos (Harvard Medical School, Boston, MA). "In countries where people eat very little fish-and some of these countries have almost no sources of omega-3 fatty acids because they cook with corn or sunflower oils-the consumption of vegetable oils with ALA could have a major impact on heart disease." In an editorial accompanying the published study [2], Dr William Harris (University of South Dakota, Sioux Falls) said that the data are suggestive and would be good news for individuals who will not or cannot eat fish, but more studies are still needed. "If ALA were able to do the same 'heavy lifting' that [eicosapentaenoic acid] EPA and [docosahexaenoic acid] DHA do, this would be welcomed news, because the capacity to produce ALA is essentially limitless, whereas there are only so many fish in the sea," he writes.

Only about half of the world's population has access to clean drinking water, leaving the other 3 billion people to fight for a source of quality water. In addition to that, according to United Nations Educational, Scientific and Cultural Organization (UNESCO); 783 Million people have no access to any clean water sources.

Mango Dash: THE VARIETIES OF LITCHI AND It's CULTIVARS - 0 views

  •  

    The summer season each year brings wafting memories of a juicy and luscious fruit called litchi. The origins of Litchi lie in southern China where as a crop it has been cultivated uninterruptedly for close to 2500 years. Its geographical propagation has been rather slow, which is due to the short life-span of its seed and the peculiar soil and climatic requirements associated with the plant.A classical instance of this is India which is the second largest producer just behind China, but litchi farming is chronologically speaking, very recent having been introduced only sometime in the middle of the 1700's. Together China and India between themselves produce more than 90% of the world's Litchi, leaving the rest of the world far behind. In the backdrop of all this it is interesting to know the various cultivars and varieties which dot the world of Litchi farming. Most or all of them have their genesis probably in China but have been suitably bred and modified to thrive in countries of their adoption.

    The terms 'cultivar' and 'variety' have often been used interchangeably but this convention often seems to ignore the obvious differences which exist between the two. A 'cultivar' is bred with the help of vegetative propagation, which could include cutting, grafting,budding and tissue culture and is a product of human effort and ingenuity. A 'variety' on the other hand is a natural phenomenon and is bred through seedlings. A 'variety' will always produce clones of the parent plant, but in a cultivar,there may be slight variation in a progeny compared to the parent particularly in the case of hybrids. The Litchi cultivars in India number about 40 out of which around 12 or 13 are commercially cultivated.The same cultivar or variety may be known by different names in various parts of the country. In China there are about 200 known cultivars although only 20 or so are in commercial farming, which means the genetic repository is much more widespread compar

    In a study of 161,808 women who were part of the government-funded Women's Health Initiative research effort, doctors from 40 centers around the country collected data on multivitamin use. While research shows that people who eat nutrient-rich diets filled with fruits and vegetables have lower rates of heart disease and cancer, it hasn't been clear whether taking a daily supplement results in a similar benefit.

The roles of calcium and vitamin D in skeletal health: an evolutionary perspective - Ro... - 0 views

  •  
    Robert P. Heaney is John A. Creighton University Professor, Creighton University, Omaha, Nebraska, United States. Hominid evolution took place in an environment (equatorial East Africa) that provided a superabundance of both calcium and vitamin D, the first in available foods and the second through conversion of 7-dehydrocholesterol to pre-vitamin D in the skin, a reaction catalysed by the intense solar ultraviolet (UV) radiation. Seemingly as a consequence, the evolving human physiology incorporated provisions to prevent the potential of toxic excesses of both nutrients. For vitamin D the protection was of two sorts: skin pigmentation absorbed the critical UV wavelengths and thereby limited dermal synthesis of cholecalciferol; and slow delivery of vitamin D from the skin into the bloodstream left surplus vitamin in the skin, where continuing sun exposure led to its photolytic degradation to inert compounds. For calcium, the adaptation consisted of very inefficient calcium absorption, together with poor to absent systemic conservation. The latter is reflected in unregulated dermal calcium losses, a high sensitivity of renal obligatory calcium loss to other nutrients in the diet and relatively high quantities of calcium in the digestive secretions. Today, chimpanzees in the original hominid habitat have diets with calcium nutrient densities in the range of 2 to 2.5 mmol per 100 kcal, and hunter-gatherer humans in Africa, South America and New Guinea still have diets very nearly as high in calcium (1.75 to 2 mmol per 100 kcal) (Eaton and Nelson, 1991). With energy expenditure of 3 000 kcal per day (a fairly conservative estimate for a contemporary human doing physical work), such diets would provide substantially in excess of 50 mmol of calcium per day. By contrast, median intake in women in North America and in many European countries today is under 15 mmol per day. Two factors altered the primitive situation: the migration of humans from Africa to higher latitude

What If Vitamin D Deficiency Is a Cause of Autism?: Scientific American - 0 views

  •  
    A few researchers are turning their attention to the sunshine vitamin as a culprit, prompted by the experience of immigrants that have moved from their equatorial country to two northern latitude locations As evidence of widespread vitamin D deficiency grows, some scientists are wondering whether the sunshine vitamin-once only considered important in bone health-may actually play a role in one of neurology's most vexing conditions: autism. The idea, although not yet tested or widely held, comes out of preliminary studies in Sweden and Minnesota. Last summer, Swedish researchers published a study in Developmental Medicine and Child Neurology that found the prevalence of autism and related disorders was three to four times higher among Somali immigrants than non-Somalis in Stockholm. The study reviewed the records of 2,437 children, born between 1988 and 1998 in Stockholm, in response to parents and teachers who had raised concerns about whether children with a Somali background were overrepresented in the total group of children with autism

    Vitamin D deficiency and bone health in healthy adults in Finland: could this be a concern in other parts of Europe? Lamberg-Allardt CJ, Outila TA, Kärkkainen MU, Rita HJ, Valsta LM. J Bone Miner Res. 2001 Nov;16(11):2066-73. PMID: 11697803 Low vitamin D status was prevalent in these young adults in northern Europe in winter, although the vitamin D intake met the recommendation. This probably is not a local problem for northern Europe, because the natural sources of vitamin D are scarce and fortification is not very common in Europe, and with the exception of the southern part of Europe, sunshine is not very abundant in this part of the world. Thus, the results of this study indicate that more attention should be focused on vitamin D status and the sources of vitamin D in these countries.

Causes of disturbances in acid-base balance - Acid-base balance, dentinogenesis and den... - 0 views

  •  
    The most common imbalance in the acid-base balance in the industrialized countries is mild chronic metabolic acidosis caused by the diet rich in the animal protein. Proteins are metabolized to organic acids. The typical American diet produces after metabolism approximately 100 meq of acid every day (Barzel 1995). This kind of a diet has been proved to cause aciduria and calciuria as a consequence of acidosis and thus a loss of total calcium of the body (Breslau et al. 1988, Schuette et al. 1980, Licata et al. 1981). Cola drinks that contain phosphoric acid are another acidosis-inducing ingredient of diet, especially among young people (Barzel 1995).
