Animal Pharm: Vitamin A - 1 views

  •  
    Looking at journals of animal farm science, studies for increasing USDA Grades of beef and Marbling Scores (MS) have yielded some interesting perspectives regarding vitamin A and its role in controlling obesity. Do Americans get enough vitamin A? The beef industry has figured out that better grades and thus higher market value can be achieved by restricting vitamin A in the food fed to commercial cows. In fact, by depleting liver stores and restricting the content in food, the grade of meat and percentage of intramuscular (IM) fat increase quite substantially. Better yield for livestock owners. Higher levels of blood glucose (BG) are also associated with lower vitamin A status and higher marbling.

    Healthy elderly French women living at home have secondary hyperparathyroidism and high bone turnover in winter. EPIDOS Study Group. Chapuy MC, Schott AM, Garnero P, Hans D, Delmas PD, Meunier PJ. J Clin Endocrinol Metab. 1996 Mar;81(3):1129-33. PMID: 8772587 These results show that vitamin D status of a French aged population in good health and living at home depends mainly on lifestyle. Like institutionalized women, old women living at home exhibit clear evidence of senile hyperparathyroidism in the winter, secondary in part to a reduced 25OHD level and associated with biological signs of increased bone turnover. The maintenance of PTH within the normal range for healthy adults by vitamin D and calcium treatment might constitute an approach for the prevention of bone loss in the entire

    A high prevalence of hypovitaminosis D in Finnish medical in- and outpatients. Kauppinen-Mäkelin R, Tähtelä R, Löyttyniemi E, Kärkkäinen J, Välimäki MJ. J Intern Med. 2001 Jun;249(6):559-63. PMID: 11422663 DOI: 10.1046/j.1365-2796.2001.00847.x CONCLUSION: Hypovitaminosis D is very common amongst Finnish in- and outpatients in both sexes, causing secondary hyperparathyroidism in females. More extensive studies are warranted to elucidate the vitamin D status of the Finnish population.

Assessment of dietary vitamin D requirements during pregnancy and lactation -- Hollis and Wagner 79 (5): 717 -- American Journal of Clinical Nutrition - 0 views

  •  
    Assessment of dietary vitamin D requirements during pregnancy and lactation. Hollis BW, Wagner CL. Am J Clin Nutr. 2004 May;79(5):717-26. Review. PMID: 15113709 We found that high-dose maternal vitamin D supplementation not only improves the nutritional vitamin D status of breastfeeding infants but also elevates the maternal concentrations into the mid-normal range. Thus, a dual benefit is achieved from high-dose maternal supplementation. It is noteworthy that in the Finnish study, the authors added a disclaimer, "A sufficient supply of vitamin D to the breastfed infant is achieved only by increasing the maternal supplementation up to 2000 IU/d. Such a dose is far higher than the RDA [DRI] for lactating mothers [and therefore] its safety over prolonged periods is not known and should be examined by further study." This point of concern was valid when this study was conducted in 1986 (92); however, on the basis of the current findings of Vieth et al (2) and of Heaney et al (3)-which showed that vitamin D intakes <= 10 000 IU/d (250 µg) are safe for prolonged periods (up to 5 mo)-we believe that it is time to reexamine the understated DRI of vitamin D for lactating mothers. This work is now being conducted in our clinics and laboratory.

Vitamin D vs broad spectrum phototherapy in the treatment of seasonal affective disorder. - [J Nutr Health Aging. 1999] - PubMed Result - 0 views

  •  
    Vitamin D vs broad spectrum phototherapy in the treatment of seasonal affective disorder. Gloth FM 3rd, Alam W, Hollis B. J Nutr Health Aging. 1999;3(1):5-7. PMID: 10888476 All subjects receiving vitamin D improved in all outcome measures. The phototherapy group showed no significant change in depression scale measures. Vitamin D status improved in both groups (74% vitamin D group, p < 0.005 and 36% phototherapy group, p < 0.01). Improvement in 25-OH D was significantly associated with improvement in depression scale scores (r2=0.26; p=0.05). Vitamin D may be an important treatment for SAD. Further studies will be necessary to confirm these findings..

Vitamin D deficiency is the cause of common obesity - 0 views

    Vitamin D deficiency is the cause of common obesity. Foss YJ. Med Hypotheses. 2009 Mar;72(3):314-21. Epub 2008 Dec 2. PMID: 19054627 doi:10.1016/j.mehy.2008.10.005 Common obesity and the metabolic syndrome may therefore result from an anomalous adaptive winter response. The stimulus for the winter response is proposed to be a fall in vitamin D. The synthesis of vitamin D is dependent upon the absorption of radiation in the ultraviolet-B range of sunlight. At ground level at mid-latitudes, UV-B radiation falls in the autumn and becomes negligible in winter. It has previously been proposed that vitamin D evolved in primitive organisms as a UV-B sensitive photoreceptor with the function of signaling changes in sunlight intensity. It is here proposed that a fall in vitamin D in the form of circulating calcidiol is the stimulus for the winter response, which consists of an accumulation of fat mass (obesity) and the induction of a winter metabolism (the metabolic syndrome). Vitamin D deficiency can account for the secular trends in the prevalence of obesity and for individual differences in its onset and severity. It may be possible to reverse the increasing prevalence of obesity by improving vitamin D status.

    Ecological studies of ultraviolet B, vitamin D and cancer since 2000. Grant WB, Mohr SB. Ann Epidemiol. 2009 Jul;19(7):446-54. Epub 2009 Mar 9. Review. PMID: 19269856 CONCLUSION: These findings provide strong evidence that vitamin D status plays an important role in controlling the outcome of cancer. Support for the UVB-vitamin D-cancer theory is now scientifically strong enough to warrant use of vitamin D in cancer prevention, and as a component of treatment. More research studies would help to explore whether there are benefits beyond the substantial effects that have been observed.

Proanthocyanidin - Wikipedia, the free encyclopedia - 0 views

  •  
    "Proanthocyanidin (PA or PAC), also known as procyanidin, oligomeric proanthocyanidin (OPC), leukocyanidin, leucoanthocyanin and condensed tannins, is a class of flavanols. Proanthocyanidins are essentially polymer chains of flavonoids such as catechins.[1] One was discovered in 1936 by Professor Jacques Masquelier and called Vitamin P, although this name did not gain official category status and has since fallen out of usage. It was Masquelier who first developed techniques for the extraction of proanthocyanidins from certain plant species. Proanthocyanidins have been sold as nutritional and therapeutic supplements in Europe since the 1980s, but their introduction to the United States market has been relatively recent. In the human body, they might act as antioxidants (free radical scavengers).[citation needed] OPCs may help protect against the effects of internal and environmental stresses such as cigarette smoking and pollution, as well as supporting normal body metabolic processes. The effects may include depressing blood fat, emolliating blood vessels, lowering blood pressure, preventing blood vessel scleroses, dropping blood viscidity and preventing thrombus formation [18]. Additionally, studies have shown that OPCs may prevent cardiovascular diseases by counteracting the negative effects of high cholesterol on the heart and blood vessels. Pycnogenol® is the name of such an OPCs commercial formulation. OPCs are available from fresh grapes, grape juice, and red wine. Although in milligrams per ounce red wine may contain more OPCs than red grape juice, red grape juice contains more OPCs per average serving size. An 8 ounce serving of grape juice averages 124 milligrams OPCs, while a 5 ounce serving of red wine averages 91 milligrams.[19][20] Many other foods and beverages also contain high amounts of OPCs, but very few come close to the levels found in red grape seeds and skins (which readily disperse into grape juice when crushed)

Dietary composition modulates brain mass and amyloid beta levels in a mouse model of aggressive Alzheimer's amyloid pathology - Molecular Neurodegeneration | Full text - 0 views

    Dietary composition modulates brain mass and solubilizable Abeta levels in a mouse model of aggressive Alzheimer's amyloid pathology. Pedrini S, Thomas C, Brautigam H, Schmeidler J, Ho L, Fraser P, Westaway D, Hyslop PS, Martins RN, Buxbaum JD, Pasinetti GM, Dickstein DL, Hof PR, Ehrlich ME, Gandy S. Mol Neurodegener. 2009 Oct 21;4:40. PMID: 19845940 doi:10.1186/1750-1326-4-40 INTERPRETATION: Dissociation of Abeta changes from brain mass changes raises the possibility that diet plays a role not only in modulating amyloidosis but also in modulating neuronal vulnerability. However, in the absence of a study of the effects of a high protein/low carbohydrate diet on nontransgenic mice, one cannot be certain how much, if any, of the loss of brain mass exhibited by high protein/low carbohydrate diet-fed TgCRND8 mice was due to an interaction between cerebral amyloidosis and diet. Given the recent evidence that certain factors favor the maintenance of cognitive function in the face of substantial structural neuropathology, we propose that there might also exist factors that sensitize brain neurons to some forms of neurotoxicity, including, perhaps, amyloid neurotoxicity. Identification of these factors could help reconcile the poor clinicopathological correlation between cognitive status and structural neuropathology, including amyloid pathology.

Vitamin D and calcium insufficiency-related chronic diseases: molecular and cellular pathophysiology - European Journal of Clinical Nutrition - Abstract of article - 0 views

    Vitamin D and calcium insufficiency-related chronic diseases: molecular and cellular pathophysiology. Peterlik M, Cross HS. Eur J Clin Nutr. 2009 Dec;63(12):1377-86. Epub 2009 Sep 2. PMID: 19724293 doi:10.1038/ejcn.2009.105 A compromised vitamin D status, characterized by low 25-hydroxyvitamin D (25-(OH)D) serum levels, and a nutritional calcium deficit are widely encountered in European and North American countries, independent of age or gender. Both conditions are linked to the pathogenesis of many degenerative, malignant, inflammatory and metabolic diseases. Studies on tissue-specific expression and activity of vitamin D metabolizing enzymes, 25-(OH)D-1alpha-hydroxylase and 25-(OH)D-24-hydroxylase, and of the extracellular calcium-sensing receptor (CaR) have led to the understanding of how, in non-renal tissues and cellular systems, locally produced 1,25-dihydroxyvitamin D3 (1,25-(OH)2D3) and extracellular Ca2+ act jointly as key regulators of cellular proliferation, differentiation and function. Impairment of cooperative signalling from the 1,25-(OH)2D3-activated vitamin D receptor (VDR) and from the CaR in vitamin D and calcium insufficiency causes cellular dysfunction in many organs and biological systems, and, therefore, increases the risk of diseases, particularly of osteoporosis, colorectal and breast cancer, inflammatory bowel disease, insulin-dependent diabetes mellitus type I, metabolic syndrome, diabetes mellitus type II, hypertension and cardiovascular disease. Understanding the underlying molecular and cellular processes provides a rationale for advocating adequate intake of vitamin D and calcium in all populations, thereby preventing many chronic diseases worldwide.

Vitamin D and Disease Incidence Prevention | Free The Animal - 0 views

    "For what reason I don't know, but this January 2009 editorial by William Faloon of the Life Extension Foundation is making the rounds. Perhaps it just came available on the web. It's a good read, particularly in light of the billions and trillions of dollars the thieves & thugs in DC are about to flush down the crapper on your behalf. Some notable excerpts. A large number of new vitamin D studies have appeared in the scientific literature since I wrote my plea to the federal government. These studies don't just confirm what we knew 16 months ago-they show that optimizing vitamin D intake will save even more lives than what we projected. For instance, a study published in June 2008 showed that men with low vitamin D levels suffer 2.42 times more heart attacks. Now look what this means in actual body counts. Each year, about 157,000 Americans die from coronary artery disease-related heart attacks. Based on this most recent study, if every American optimized their vitamin D status, the number of deaths prevented from this kind of heart attack would be 92,500. To put the number of lives saved in context, tens of millions of dollars are being spent to advertise that Lipitor® reduces heart attacks by 37%. This is certainly a decent number, but not when compared with how many lives could be saved by vitamin D. According to the latest study, men with the higher vitamin D levels had a 142% reduction in heart attacks."

Evo and Proud: African Americans and vitamin D - 0 views

  •  
    "It's well known that African Americans have low levels of vitamin D in their blood. In fact, this seems to be generally true for humans of tropical origin. In a study from Hawaii, vitamin D status was assessed in healthy, visibly tanned young adults who averaged 22.4 hours per week of unprotected sun exposure. Yet 51% had levels below the current recommended minimum of 75 nmol/L (Binkley et al., 2007). In a study from south India, levels below 50 nmol/L were found in 44% of the men and 70% of the women. The subjects are described as "agricultural workers starting their day at 0800 and working outdoors until 1700 with their face, chest, back, legs, arms, and forearms exposed to sunlight" (Harinarayan et al., 2007). In a study from Saudi Arabia, levels below 25 nmol/L were found in respectively 35%, 45%, 53%, and 50% of normal male university students of Saudi, Jordanian, Egyptian, and other origins (Sedrani, 1984)."

GrassrootsHealth | Vitamin D Action - Vitamin D Scientists' Call to Action Statement - 0 views

  •  
    "We are aware of substantial scientific evidence supporting the role of vitamin D in prevention of cancer. It has been reasonably established that adequate serum vitamin D metabolite levels are associated with substantially lower incidence rates of several types of cancer, including those of the breast, colon, and ovary, and other sites. We have concluded that the vitamin D status of most individuals in North America will need to be greatly improved for substantial reduction in incidence of cancer. Epidemiological studies have shown that higher vitamin D levels are also associated with lower risk of Type I diabetes in children and of multiple sclerosis. Several studies have found that markers of higher vitamin D levels are associated with lower incidence and severity of influenza and several other infectious diseases."

Higher Levels of Vitamin D May Be Associated with a Lower Risk of Lung Cancer in Women and Younger Subjects by Derrick DeSilva Jr., M.D. - Alternative Health Blog - Alternative Health Journal - 0 views

  •  
    "In a prospective study involving 6,937 men and women, higher levels of vitamin D were associated with a significantly lower risk of lung cancer in women and younger participants. During a maximum follow-up of 24 years, 122 cases of lung cancer were identified. After adjusting for potential confounders, higher serum 25-hydroxyvitamin D levels were associated with reduced risk of lung cancer risk in women (84% reduced risk) and younger participants (66% reduced risk). No association was observed between vitamin D status and lung cancer risk in men and older participants. "
