    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.

    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

    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.

Vitamins can be useful, says FDA - 1 views

  •  
    "The US Food and Drug Administration has advised consumers that certain vitamin supplements "can be useful", stating that "there are many good reasons" to consider taking them. The consumer advisory, released this week in video and text format, comes at a time of increased pressure on the supplements industry, with media outlets repeatedly questioning the usefulness and safety of dietary supplements. "Supplements can be useful when they fulfill a specific identified nutrient need that can't be met by food or is not being met through normal food intake," said Barbara Schneeman, PhD, director of FDA's Office of Nutritional Products, Labeling, and Dietary Supplements. The message is one that dietary supplement trade groups have consistently tried to get across, with campaigns such as CRN's Life…supplemented set up to communicate the importan Vitamins for the right reasons According to FDA's consumer update - Fortify Your Knowledge About Vitamins - there are many good reasons to consider taking vitamin supplements, which could be recommended by a doctor in a number of situations, including: * For certain health problems * When following a vegetarian or vegan diet * When pregnant or breastfeeding Iron and folic acid are important for pregnant women or women of childbearing age, to be consumed via a varied diet or from fortified foods and supplements, says FDA. People over 50 should consume vitamin B12, and those with darker skin or with insufficient exposure to sunlight should consume extra vitamin D, again via fortified foods or supplements."

Cancer survivor credits healthful diet - denverpost.com - 0 views

    "Cancer lies dormant in all of us," he wrote in his new book, "Anticancer: A New Way of Life" (Viking, $25.95). "But our bodies are also equipped with a number of mechanisms that detect and keep such (defective) cells in check." Cancer rears its ugly head when things get out of balance, Servan-Schreiber said in an interview. And that can happen if the bad guys that promote the growth of cancer cells (tobacco, excessive alcohol, excessive sugar, hydrogenated fats, environmental pollutants) outnumber the good guys that support our natural defenses (cancer-fighting phytochemicals found in fruits, vegetables, herbs and teas; physical activity; and stress management techniques). But conventional treatment, while indispensable, focuses on a single target: destroying cancer cells. Doctors rarely address the other side: teaching patients how to fortify themselves using nutrition, exercise and stress-management techniques to create an inhospitable environment for cancer.

    Summary of evidence-based review on vitamin D efficacy and safety in relation to bone health. Cranney A, Weiler HA, O'Donnell S, Puil L. Am J Clin Nutr. 2008 Aug;88(2):513S-519S. Review. PMID: 18689393 We found inconsistent evidence of an association between serum 25-hydroxyvitamin D [25(OH)D] concentration and bone mineral content in infants and fair evidence of an association with bone mineral content or density in older children and older adults. The evidence of an association between serum 25(OH)D concentration and some clinical outcomes (fractures, performance measures) in postmenopausal women and older men was inconsistent, and the evidence of an association with falls was fair. We found good evidence of a positive effect of consuming vitamin D-fortified foods on 25(OH)D concentrations. The evidence for a benefit of vitamin D on falls and fractures varied. We found fair evidence that adults tolerated vitamin D at doses above current dietary reference intake levels, but we had no data on the association between long-term harms and higher doses of vitamin D.

    It's a fact of the grocery store that the most healthy food often has the least marketing muscle behind it. The best source of fiber and vitamins are fresh vegetables and fruit, and yet it's the processed, packaged junk food fortified with vitamin and fiber powder that screams for attention.

How this horrible weather could give you heart disease | Mail Online - 1 views

    "We are fond of grumbling about Britain's grey skies, but there may be a good medical reason for doing so. It seems the dreary weather is bad for our hearts - worse, even, than raised cholesterol and an unhealthy diet. That's the controversial claim being made by Dr David Grimes, a gastroenterologist from Blackburn. He's been gazing at the sky for 20 years for clues about why his patients get more sick than those in the south of the country. And what he's found turns key assumptions about heart disease on their head. 'It's not diet or cholesterol levels that raise your risk of heart disease,' he claims. 'It's where you live. People in the north are more likely to be ill because they get less sunshine Basically they are suffering from 'latitude' sickness. The link is vitamin D. While we get some from our diet, the main source is the sun - sunlight converts a compound in the skin into vitamin D, so the amount you make is directly related to the amount of sunshine you get. In a new book Dr Grimes argues the higher the level of vitamin D in your blood, the lower your risk of heart disease and a range of other illnesses. If he's right, what we need is not diet and lifestyle advice, but food fortified with vitamin D. For years the vitamin was thought to be useful only for preventing rickets. So how does he treat them? 'You can do it with diet,' he says 'One Bangladeshi woman eats oily fish every day and now has a vitamin D blood level of 40. 'We give supplements of 1,000 international units (IU) a day or we can give an injection of 300,000 IU that lasts for a year. 'The patients respond well,' says Grimes 'but what's needed is a proper controlled, long-term trial and who is going to fund that? Not a drug company.'"

    On an ordinary UK diet, iron is derived about one-third from animal foods, onethird from fortified breakfast cereals and one-third from the rest of the diet. The iron content of common foods is given in Table 40 and the daily iron needs in Table 41. On average, 10-15 mg are consumed each day and the efficiency of absorption is around 10 per cent

Take or avoid vitamin D supplements? - ImmInst.org Forums - 0 views

  •  
    "Hi! This is Amy Proal. I wrote the article referenced at the start of the thread about vitamin D. Dr. Marshall is not concerned with vitamin D toxicity. Rather his molecular modeling research has clarified the actions of the two vitamin D metabolites 25-D and 1,25-D. The Vitamin D Receptor (VDR) is a fundamental receptor of the body - it controls the expression thousands of genes, as well as the activity of the innate immune system and the antimicrobial peptides. If you think of the VDR as a switch, 25-D (which is a corticosteroid) turns it off (inactivates it) and 1,25-D turn it on (activates it). What is commonly believed among vitamin D researchers is that if people supplement with extra vitamin D it will be converted into 1,25-D and activate the VDR. Unfortunately, Marshall's work revealed that the type of vitamin D derived from supplements and sun remains, for the most part, in it's precursor form 25-D. This means that the extra vitamin D we get from fortified food products and supplements is turning the VDR off, not on. That causes a decrease in immune function and gene transcription."

Defining Adequate Vitamin D Intake : Cross-sectional and Intervention Studies - 0 views

  •  
    Defining Adequate Vitamin D Intake : Cross-sectional and Intervention Studies Viljakainen, Heli Tuulikki University of Helsinki 2008-05-23 Doctoral dissertation (article-based) Vitamin D is required for normal bone growth and maintenance of the skeleton throughout life. In Finland, like in many other Western countries, the population suffers from inadequate or deficient vitamin D status, especially during winter, which is thought to increase the risk of osteoporosis. New strategies to prevent osteoporosis are actively being sought. The main objective of this thesis was to determine whether vitamin D is feasible in the primary prevention of osteoporosis; does it affect bone mineral accrual during the growth period? A second goal was to ascertain whether seasonal variation in calcitropic hormones affects bone remodelling, and to elucidate the vitamin D intake needed to overcome this variation in different age groups. In summary, vitamin D intake remains inadequate among the target groups of this thesis, as reflected by seasonal variation in calcitropic hormones and bone metabolism. Dietary intake of vitamin D should be increased to achieve at least an adequate vitamin D status (S-25-OHD>50 nmol/l) and possibly an optimal vitamin D status (S-25-OHD>80 nmol/l) throughout the year. This could be accomplished by introducing new vitamin D-fortified foods to the market."

Effects Of Vitamin D Deficiency Amplified By Shortage Of Estrogen - 0 views

  •  
    "Researchers at Johns Hopkins are reporting what is believed to be the first conclusive evidence in men that the long-term ill effects of vitamin D deficiency are amplified by lower levels of the key sex hormone estrogen, but not testosterone. In a national study in 1010 men, to be presented Nov. 15 at the American Heart Association's (AHA) annual Scientific Sessions in Orlando, researchers say the new findings build on previous studies showing that deficiencies in vitamin D and low levels of estrogen, found naturally in differing amounts in men and women, were independent risk factors for hardened and narrowed arteries and weakened bones. Vitamin D is an essential part to keeping the body healthy, and can be obtained from fortified foods, such as milk and cereals, and by exposure to sunlight.

More Good News About Vitamin D | Print Article | Newsweek.com - 0 views

    "For more than 80 years, scientists have known that vitamin D is important for building bones. And for most of those 80 years, people thought this was the only thing it was good for. In the past decade, however, we've learned two important things about vitamin D: it appears to have many other important health effects, and many Americans don't get enough of it. In 2008, new research pointed to a vitamin D deficiency as a possible contributing factor in heart disease. And the suspected link between vitamin D deficiency and cancer grew even stronger. This surely will spur much new research in 2009. Why is vitamin D deficiency so common? The vitamin is made in our skin when sunlight strikes it. Many Americans-especially those who live in the northern part of the country, are elderly or have dark skin-don't soak up enough sun. And the vitamin isn't found in many foods. The main sources are fatty fish (such as salmon, mackerel, herring and sardines) and milk, cereal and juices that have been fortified with it. Vitamin D deficiency often is unsuspected because it causes no direct symptoms; like high blood pressure, it does its damage silently."
