Millions of British people are at risk of developing serious health conditions because of low vitamin D levels declares a new scientific review commissioned by the Health Supplements Information Service (HSIS). Despite the proven health benefits of vitamin D, about three quarters of British adults fail to reach even their basic requirements thanks to poor dietary intakes and a lack of sun in this country. Now nutrition experts are calling for the shortfall in our diets to be made up by improved dietary intakes and vitamin D supplementation. As studies show, supplementation has a guaranteed effect on vitamin D status. In this latest study review, called ‘Health Impacts of Vitamin D: Are We Getting Enough?’, independent researchers analysed the current evidence surrounding vitamin D. The aims were to identify the main health benefits associated with the vitamin and to explore issues surrounding optimal daily intakes. Leading dietitian, Dr Carrie Ruxton, and senior lecturer in Human Nutrition at Manchester Metropolitan University, Dr Emma Derbyshire, reviewed more than 100 published research papers relating to the potential power of vitamin D, mechanisms to explain its benefits, vitamin D intakes and recommendations. Their paper will be published in the June issue of Nutrition Bulletin, the journal of the British Nutrition Foundation. Scientific research suggests that vitamin D plays an important role in helping combat a host of serious health conditions, including cancer, heart disease, multiple sclerosis and immune disorders, as well as boosting bone health. Recent research work has linked vitamin D deficiency with a significantly increased risk of poor mental and physical health. Normally vitamin D is produced by the body following skin exposure to sunlight. However, the northern latitude of the UK means that adequate access to sunlight is only possible over 7 months of the year. During the winter months, there is simply not enough sunlight to stimulate our bodies to make vitamin D. An increased awareness of the risks of skin cancer has also limited typical skin sun exposure levels, as have cultural reasons for covering the skin. A regular intake of vitamin D-rich foods or a multivitamin rich in vitamin D can help enhance our skin production. Good food sources include oily fish, meat, fats and spreads, breakfast cereals, dairy products and eggs. However, consumption of many of these foods has declined in recent years. For example, in 1974, the average person bought 147g a week of butter compared with just 41g a week in 2007. Currently in the UK, there are no recommended intake levels of vitamin D for most adults. The European Union recommends a daily intake of 5µg (micrograms) for food labelling purposes, while the European Food Safety Authority suggests a maximum of 25µg a day for children and 50µg a day for 12 to 70 year olds. Dr Ruxton and Dr Derbyshire found that in the UK, 71 per cent of men and 78 per cent of women failed to reach even 5µg of vitamin D intake a day, with an average of just 3.7µg for men and 2.8µg for women. The recommended safe upper level in America, Australia and New Zealand is 80µg a day, but studies now suggest that levels of 500 to 1,000µg a day may well be safe. One study reported that to lower the risk of osteoporotic bone fractures, adults needed to take at least 55µg of vitamin D through diet, in addition to usual sun exposure. Commenting on the latest review commissioned by HSIS, Dr Ruxton says: “There is a growing body of literature to show that vitamin D is important for maintaining health and lowering the risk of some chronic diseases. A better vitamin D status appears to be linked with a lower risk of cardiovascular disease, diabetes and inflammatory conditions, and less cognitive impairment in older people. “Taking the evidence as a whole, a rather worrying picture emerges implying that British adults and children are at increased risk of chronic disease due to vitamin D insufficiency. We need to re-examine UK dietary recommendations for vitamin D, which were originally informed by research from the 1960s and 1970s. In particular, vitamin D recommendations for those unlikely to achieve sufficient sun exposure, or those with particular health needs, need to be addressed. “We also need to address declining intakes of foods rich in vitamin D. Most people are still failing to eat enough oily fish or low fat dairy foods which are useful sources of the vitamin. Vitamin supplementation such as taking a daily multivitamin rich in vitamin D could play a useful role in addressing low vitamin D intakes as studies show they help boost vitamin D levels in the blood. Not everyone gets all the nutrients they need from their diet so a multivitamin containing vitamin D can be a good insurance policy while long-term dietary changes are being made.” For more information on vitamins and minerals visit www.HSIS*******.

This is the VOA Special English Health Report, from *******voaspecialenglish**** Vitamin D helps bones and muscles grow strong and healthy. Low levels of vitamin D can lead to problems like rickets and osteoporosis. Rickets is a deformity mainly found in children. Osteoporosis is the thinning of bone, a common problem as people, especially women, get older. Studies in recent years have suggested that vitamin D may also have other uses. Studies have shown that low levels of D may increase the risk of heart attacks in men and deaths from some cancers. Other studies have shown that people with rheumatic diseases often have low levels of D. The easiest way to get vitamin D is from sunlight. The ultraviolet rays react with skin cells to produce the vitamin. But many people worry about skin cancer and skin damage from the sun. So they cover their skin or wear sunblock or stay out of the sun. Also, darker skinned people produce less vitamin D than lighter skinned people. Production also decreases in older people and those living in northern areas that get less sunlight. Not many foods naturally contain vitamin D. Foods with high levels include oily fish such as salmon, tuna and mackerel, and fish liver oils. Boston University researchers reported in two thousand seven that farmed salmon had a lot less vitamin D than wild salmon. Small amounts of D are found in beef liver, cheese and egg yolks. And some people take dietary supplements containing the vitamin. But most of the D in the American diet comes from foods like milk with the vitamin added. These days, more doctors are testing for vitamin D levels in their patients. But as research continues, some experts worry that if people take too much D, it might act as a poison. Also, skin doctors warn people to be careful with sun exposure because of the risk of skin cancer. How much vitamin D does a healthy person need? Nutrition experts who advise the American government set the current recommendations in nineteen ninety-seven. The daily amount is two hundred international units from birth through age fifty. Then it rises to four hundred I.U.s through age seventy, and six hundred for those seventy-one and older. But some groups say these amounts are not high enough. The nutrition experts are taking another look at how much vitamin D and calcium people should get. The Institute of Medicine of the National Academies expects to release a report by this coming May. And thats the VOA Special English Health Report. (Adapted from a radio program broadcast 23Sep2009)

www.17harleystreet****** - Vitamin D has been known about for many years and is often called the "Sunshine Vitamin". Simple exposure to sunshine and eating a diet with plenty of oily fish, are the best ways of getting Vitamin D. It is thought that one billion people are deficient in Vitamin D - that is a stunning number! One in six of the world's population are deficient in a Vitamin, that few of us think about and doctors rarely test for.

Many people have turned to fish oil supplements to enrich their diet with the Omega-3, fatty acid. This fish oil is derived from the tissues of oily fish and it is recommended for a healthy diet because it contains the fatty acids eicosapentaenoic (EPA) and docosahaexaenoic (DHA), precursors to eicosanoids that reduce inflammation through the body. Besides its anti-inflammatory properties it can also regulate cholesterol in the body. A lot of milk, yoghurt and juice companies are claiming now to have Omega added to them in order that the consumer will chose their product. The advertising may tend to deceive the end consumer to believe that the Omega he is taking from the milk is enough and there is no need for him to buy food supplements in capsule form containing the omega fish oils. A brief overview of products on the market will easily reveal claims of Omega-3 presence in milk, yoghurt, cereals, bars and juices. Unfortunately quantities and concentrations of Omega are not observed in the nutritional values well enough by the end consumer. There are huge differences with regards to quantity and percentages of Omega per 100 g, between these products and CARDIOSTEROIL a recent product of ALTA CARE Laboratoires. Cardiosteroil softgels are made in France and every softgel contains 100% of Omega while milks, yoghurts, bars and juices have not more than 0,8% of Omega that is added to them.
