    The bioavailability of vitamin D from fortified cheeses and supplements is equivalent in adults. Wagner D, Sidhom G, Whiting SJ, Rousseau D, Vieth R. J Nutr. 2008 Jul;138(7):1365-71. PMID: 18567762 Compared with baseline, serum parathyroid hormone decreased with both fortification (P = 0.003) and supplementation (P = 0.012). These data demonstrate that vitamin D is equally bioavailable from fortified hard cheeses and supplements, making cheese suitable for vitamin D fortification.

    Bread fortified with cholecalciferol increases the serum 25-hydroxyvitamin D concentration in women as effectively as a cholecalciferol supplement. Natri AM, Salo P, Vikstedt T, Palssa A, Huttunen M, Kärkkäinen MU, Salovaara H, Piironen V, Jakobsen J, Lamberg-Allardt CJ. J Nutr. 2006 Jan;136(1):123-7. PMID: 16365070 Both fortified breads increased serum 25-hydroxyvitamin D concentration as effectively as the cholecalciferol supplement. Supplementation or fortification did not affect serum intact parathyroid hormone concentration or urinary calcium excretion. In conclusion, fortified bread is a safe and feasible way to improve vitamin D nutrition.

Vitamin D and calcium insufficiency-related chronic diseases: molecular and cellular pa... - 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.

Vytorin Recall: New study shows vytorin and zetia less effective than niacin | Beasley ... - 0 views

  •  
    "Vytorin has struck out again, this time in a clinical trial that compared the drug's safety and efficacy to a prescription form of the B vitamin niacin. The results of the trial, which the New England Journal of Medicine featured in an article and two editorials, were presented Sunday at an American Heart Association meeting and showed that in a direct comparison, niacin worked significantly better than Vytorin and Zetia in reducing arterial blockages. According to a report in NPR, "This study is the third to question whether ezetimibe drugs do what they're supposed to." If lowering LDL or "bad" cholesterol is the doctor's sole intention when prescribing Vytorin to patients, then the drug does a great job. However, as previous studies have shown, lower levels of LDL cholesterol don't automatically translate to cleaner arteries and lower incidences of cardiac arrest. While Vytorin worked better than statins combined with time-release Niacin to lower LDL cholesterol in 200 patients, its performance was inferior in reducing artery clogging deposits."

    "Study highlights: * Ginkgo biloba doesn't prevent cardiovascular death, heart attacks or strokes, and should not be recommended as a way to prevent them. * Further research should explore its potential benefit to people with peripheral vascular disease. DALLAS, Nov. 24, 2009 - Ginkgo biloba didn't prevent cardiovascular death or major events such as heart attack and stroke in people age 75 and older, but the herb may affect peripheral vascular disease, according to research reported in Circulation: Cardiovascular Quality and Outcomes, a journal of the American Heart Association. "Surprisingly, Ginkgo was associated with a reduction in peripheral artery disease, but the number of patients was small. The difference was statistically significant," said Lewis H. Kuller, M.D., Dr.P.H., first author of the study and distinguished university professor of public health and professor of epidemiology at the University of Pittsburgh. Gingko biloba contains a class of nutrients - flavonoids - found in fruits, vegetables, dark chocolate and red wine, which are believed to offer some protection against cardiovascular events. "

    "Want more of that good HDL cholesterol? Try a timed-release niacin, and be skeptical if your doctor gives the sales pitch for Zetia or Vytorin. The authority for this is a study dubbed ARBITER-6, which was stopped suddenly this summer, with the study's authors insisting safety had nothing to do with it. It was a question of efficacy. The results, described in the New England Journal of Medicine, make clear that niacin does better at the main job, keeping arteries open"

Ginkgo biloba - Wikipedia, the free encyclopedia - 0 views

  •  
    Ginkgo has many alleged nootropic properties, and is mainly used as memory[25] and concentration enhancer, and anti-vertigo agent. However, studies differ about its efficacy. The largest and longest independent clinical trial to assess ginkgo biloba's ability to prevent memory loss has found that the supplement does not prevent or delay dementia or Alzheimer's disease.[26] Some controversy has arisen over the conclusions drawn by some studies that were allegedly funded by a firm which marketed Ginkgo.[27] In 2002, a long-anticipated paper appeared in JAMA (Journal of the American Medical Association) titled "Ginkgo for memory enhancement: a randomized controlled trial." This Williams College study, sponsored by the National Institute on Aging rather than Schwabe, examined the effects of ginkgo consumption on healthy volunteers older than 60. The conclusion, now cited in the National Institutes of Health's ginkgo fact sheet, said: "When taken following the manufacturer's instructions, ginkgo provides no measurable benefit in memory or related cognitive function to adults with healthy cognitive function." ... The impact of this seemingly damning assessment, however, was ameliorated by the almost simultaneous publication of a Schwabe-sponsored study in the less prestigious Human Psychopharmacology. This rival study, conducted at Jerry Falwell's Liberty University, was rejected by JAMA, and came to a very different-if not exactly sweeping-conclusion: There was ample evidence to support "the potential efficacy of Ginkgo biloba EGb 761 in enhancing certain neuropsychological/memory processes of cognitively intact older adults, 60 years of age and over." According to some studies, in a few cases, Ginkgo can significantly improve attention in healthy individuals.[28][29] Allegedly, the effect is almost immediate and reaches its peak in 2.5 hours after the intake.[30] [edit] In dementia A 2004 conference paper[31] summarizes how various trials indicate that Gi

Whole Health Source: The Dirty Little Secret of the Diet-Heart Hypothesis - 0 views

  •  
    "The diet-heart hypothesis is the idea that saturated fat, and in some versions cholesterol, raises blood cholesterol and contributes to the risk of having a heart attack. To test this hypothesis, scientists have been studying the relationship between saturated fat consumption and heart attack risk for more than half a century. To judge by the grave pronouncements of our most visible experts, you would think these studies had found an association between the two. It turns out, they haven't. The fact is, the vast majority of high-quality observational studies have found no connection whatsoever between saturated fat consumption and heart attack risk. The scientific literature contains dozens of these studies, so let's narrow the field to prospective studies only, because they are considered the most reliable. In this study design, investigators find a group of initially healthy people, record information about them (in this case what they eat), and watch who gets sick over the years."

Artemisinin - Wikipedia, the free encyclopedia - 0 views

  •  
    Artemisinin (pronounced /ɑːtə'misinən/) is a drug used to treat multi-drug resistant strains of falciparum malaria. The compound (a sesquiterpene lactone) is isolated from the plant Artemisia annua. Not all plants of this species contain artemisinin. Apparently it is only produced when the plant is subjected to certain conditions, most likely biotic or abiotic stress. It can be synthesized from artemisinic acid.[1] The drug is derived from a herb used in Chinese traditional medicine, though it is usually chemically modified and combined with other medications. Artemisinin is under early research and testing for treatment of cancer, primarily by researchers at the University of Washington.[7][8] Artemisinin has a peroxide lactone group in its structure. It is thought that when the peroxide comes into contact with high iron concentrations (common in cancerous cells), the molecule becomes unstable and releases reactive oxygen species. It has been shown to reduce angiogenesis and the expression of vascular endothelial growth factor in some tissue cultures.

Animal Pharm: Benefits of High-Saturated Fat Diets (Part V): The Traditional Okinawans - 0 views

  •  
    According to Dr. Willcox, Principal Investor for the Okinawa Centenarian Study that started in 1975, "Among the entire population, which takes a sparing approach to food, there is 90 percent less coronary artery disease than in the wider world, a third less incidence of cancer, and breast cancer is virtually unheard of." HERE. In long-living Okinawan and Japanese, their dietary intake as surveyed in the 1970s was higher in both protein and dietary saturated fatty acids (see below abstract) compared to their shorter-lived peers at that time. When Okinawans move away (like to Brazil) heart disease risk factors appear (see last abstract). Diet is 80-90% of our health I believe because our bodies are designed to express what is dictated by our environment and food macro- micronutrients (foraging/hunting v. lounging; fecundity v. fasting). (These are the PPAR alpha gamma and delta receptors; their role is to 'sense nutrients' and to 'sense energy demand' in order to ultimately balance our energy needs). To me, the observations from blue zones and centenarian data always seem to reinforce that the physically active, low carb mod-high fat Paleo/TYP approach is the most optimal at this time, as it was for centenarians studied in the 1970s.
