    Estimation and fortification of vitamin D3 in pasteurized process cheese. Upreti P, Mistry VV, Warthesen JJ. J Dairy Sci. 2002 Dec;85(12):3173-81. PMID: 12512590 The objective of this study was to develop methods for the estimation and fortification of vitamin D3 in pasteurized Process cheese. Vitamin D3 was estimated using alkaline saponification at 70°C for 30 min, followed by extraction with petroleum ether:diethyl ether (90:10 vol/vol) and HPLC. The retention time for vitamin D3 was approximately 9 min. A standard curve with a correlation coefficient of 0.972 was prepared for quantification of vitamin D3 in unknown samples. In the second phase of the study, pasteurized Process cheeses fortified with commercial water- or fat-dispersible forms of vitamin D3 at a level of 100 IU per serving (28 g) were manufactured. There was no loss of vitamin D3 during Process cheese manufacture, and the vitamin was uniformly distributed. No losses of the vitamin occurred during storage of the fortified cheeses over a 9-mo period at 21 to 29°C and 4 to 6°C. There was an approximately 25 to 30% loss of the vitamin when cheeses were heated for 5 min in an oven maintained at 232°C. Added vitamin D3 did not impart any off flavors to the Process cheeses as determined by sensory analysis. There were no differences between the water- and fat-dispersible forms of the vitamin in the parameters measured in fortified cheeses

    Dietary recommendations for vitamin D: a critical need for functional end points to establish an estimated average requirement. Whiting SJ, Calvo MS. J Nutr. 2005 Feb;135(2):304-9. Review. PMID: 15671232 In summary, vitamin D has emerged as a critical nutrient for which there is a compelling health need to establish adequate dietary guidelines in North America and worldwide given the increasing evidence of vitamin D deficiency and insufficient links to risk of chronic disease. We strongly argue that now there are enough data to consider setting an estimated average requirement for vitamin D and to recognize the crucial need for more research to determine the role of vitamin D in noncalciotropic functions and prevention of chronic diseases

Whole Health Source: Composition of the Hunter-Gatherer Diet - 0 views

  •  
    I bumped into a fascinating paper today by Dr. Loren Cordain titled "Plant-Animal Subsistence Ratios and Macronutrient Estimations in Worldwide Hunter-Gatherer Diets." Published in 2000 in the American Journal of Clinical Nutrition, the paper estimates the food sources and macronutrient intakes of historical hunter-gatherers based on data from 229 different groups. Based on the available data, these groups did not suffer from the diseases of civilization. This is typical of hunter-gatherers. Initial data came from the massive Ethnographic Atlas by Dr. George P. Murdock, and was analyzed further by Cordain and his collaborators. Cordain is a professor at Colorado State University, and a longtime proponent of paleolithic diets for health. He has written extensively about the detrimental effects of grains and other modern foods. Here's his website.

    A comparison of egg consumption with other modifiable coronary heart disease lifestyle risk factors: a relative risk apportionment study. Barraj L, Tran N, Mink P. Risk Anal. 2009 Mar;29(3):401-15. Epub 2008 Nov 4. PMID: 19000074 DOI: 10.1111/j.1539-6924.2008.01149.x Guidelines from the American Heart Association (AHA) recommend that healthy adults limit their intake of dietary cholesterol to less than 300 mg per day. Since a large egg contains about 71% of that amount, the AHA recommends restricting egg consumption unless dietary cholesterol intakes from other sources are limited. We applied a risk apportionment approach to estimate the contribution of egg consumption and other modifiable lifestyle risk factors (e.g., smoking, poor diet, minimal exercise, and alcohol intake) to coronary heart disease (CHD) risk at the population level. Specifically, we categorized the U.S. adult population ages 25+ into distinct risk groups based on the prevalence of modifiable lifestyle risk factors and applied an apportionment model, typically used to assess risk contribution at the individual level, to estimate the contribution of egg intake to CHD risk. Our analysis shows that the combination of modifiable lifestyle risk factors accounts for less than 40% of the population CHD mortality. For the majority of U.S. adults age 25+, consuming one egg a day accounts for <1% of CHD risk. Hence, focusing on decreasing egg intake as an approach to modify CHD risk would be expected to yield minimal results relative to changing other behaviors such as smoking and other dietary habits.

    Plant-animal subsistence ratios and macronutrient energy estimations in worldwide hunter-gatherer diets. Cordain L, Miller JB, Eaton SB, Mann N, Holt SH, Speth JD. Am J Clin Nutr. 2000 Mar;71(3):682-92. PMID: 10702160 Our analysis showed that whenever and wherever it was ecologically possible, hunter-gatherers consumed high amounts (45-65% of energy) of animal food. Most (73%) of the worldwide hunter-gatherer societies derived >50% (> or =56-65% of energy) of their subsistence from animal foods, whereas only 14% of these societies derived >50% (> or =56-65% of energy) of their subsistence from gathered plant foods. This high reliance on animal-based foods coupled with the relatively low carbohydrate content of wild plant foods produces universally characteristic macronutrient consumption ratios in which protein is elevated (19-35% of energy) at the expense of carbohydrates (22-40% of energy).

    Written by, Samuel K. Burlum, Investigative Reporter and author of The Green Lane, a syndicated column Published on 4/30/16, a SamBurlum.com Exclusive Source: As we take a look at the poor water quality issues that have hit major metro centers such as Flint, Michigan and Newark, New Jersey, we examine the source of these issues and what some are doing to rush in protecting the most important natural resource vital to the existence of the human race. As our world's population grows and our available sources of clean drinkable freshwater dwindle, the race to find ways to preserve and protect our current water supplies have rapidly increased; while other alternatives on how to clean up used and polluted water supplies are explored. Schools of thought and tech companies are eager to find ways to filter recycled water for reuse; fresh water supplies continue to be maxed out. According to the U.S. Geological Survey; only 2.5% of the Earth's water supply is fresh water. The main sources of available drinkable freshwater supply mainly come from glaciers and ice caps; ground ice and permafrost, and lakes and ground water. It is so surprising that with this natural resource being so scarce, we as a society don't do more to preserve and protect it. And so as a society, we continue to sabotage ourselves by contributing to actions and behaviors that increase pollution of our rivers and lakes. 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. They must rely on "dirty" water or no water at all. This seems like a problem that would only plague impoverished countries, countries without infrastructure and societies without developed economies; however that stereo-typical outlook has been crushed by

  •  
    An estimated 50% to 60% of older people have suboptimal vitamin D levels, which is a problem that could affect more than bone health. Recent cross-sectional studies have also shown an association between low vitamin D levels and cardiovascular disease, hypertension, and metabolic syndrome. In a long-term prospective study from Germany, researchers assessed whether 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D levels were associated with all-cause and cardiovascular mortality among more than 3000 consecutive patients (mean age, 62) referred for coronary angiography.

Not enough vitamin D: Health consequences for Canadians -- Schwalfenberg 53 (5): 841 --... - 0 views

    Not enough vitamin D: health consequences for Canadians. Schwalfenberg G. Can Fam Physician. 2007 May;53(5):841-54. Review PMID: 17872747 Conclusion Low levels of VTD are considered a major public health problem in Canada, especially during the winter. Those with risk factors should be screened for low 25(OH)D levels and repletion therapy instituted if needed. Researchers have estimated that the oral dose of vitamin D3 to attain and maintain 25(OH)D levels >80 nmol/L is 2200 IU/d if baseline levels are 20 to 40 nmol/L, 1800 IU/d if levels are 40 to 60 nmol/L, and 1160 IU/d if levels are between 60 and 80 nmol/L.64 We need to ensure that patients have healthy blood levels of 25(OH)D to prevent levels of parathyroid hormone from rising and to maximize absorption of calcium, magnesium, and phosphate. Positive effects on bone are marginal at best unless patients consume at least 800 IU/d of VTD. The emerging and exciting role of the VTD receptor and the actions of VTD in maintaining health in other cell types have become more apparent during the last decade.
