    • Most Kids Have Low Vitamin D Levels


      By Stephen Daniells, Nutra Ingredients USA

      The majority of American children are not getting sufficient vitamin D from sun exposure, even in summer months, says a new analysis from leading researchers.

      According to findings published in Environmental Health Perspectives, only children with type II skin (Caucasian) living in the northern US actually achieved the minimum daily dose of vitamin D and this only occurred in the summer months if they did not wear sunscreen.

      The statistics were increased for children with all skin types living in the southern US in summer, but only children with the fairer skin achieved the minimum daily dose in spring.

      “Our estimates suggest that many children may not get enough sun exposure to meet their minimum daily vitamin D requirements,” concluded researchers led by Dianne Godar, PhD, from the US Food and Drug Administration (FDA).

      “However, additional research is needed to confirm our estimates, and improve our understanding of the net benefits and risks of sun exposure to children’s health.”

      The vitamin

      Vitamin D refers to two biologically inactive precursors - D3, also known as cholecalciferol, and D2, also known as ergocalciferol. The former, produced in the skin on exposure to UVB radiation (290 to 320 nm), is said to be more bioactive.

      Both D3 and D2 precursors are hydroxylated in the liver and kidneys to form 25- hydroxyvitamin D (25(OH)D), the non-active 'storage' form, and 1,25-dihydroxyvitamin D (1,25(OH)2D), the biologically active form that is tightly controlled by the body.

      While our bodies do manufacture vitamin D on exposure to sunshine (UV-B radiation with a wavelength between 290 and 315 nm), the levels in some northern countries are so weak during the winter months that our body makes no vitamin D at all, meaning that dietary supplements and fortified foods are seen by many as the best way to boost intakes of vitamin D.

      New analysis

      The researchers calculated average vitamin D production from sun exposure according to gender, age, skin type, clothing and the season for children living in the northern (45°N) and southern (35°N) US.

      “Our estimates suggest that American children may not be getting adequate outdoor UVB exposures to satisfy their vitamin D3 needs all year, except some Caucasians during the summer if they do not diligently wear sunscreens except during beach vacations,” wrote Dr Godar and her co-workers.

      The results challenge conclusions by the American Academy of Dermatology, which states that people will still make “ample” vitamin D3 (at least 1,000 IU/day) because they get plenty of “casual” (everyday) exposure to UV out side.

      The role for supplements

      The data clearly shows the importance of vitamin D supplements and fortified foods. Earlier this year, renowned vitamin D researcher, Michael Holick PhD, MD, Professor of Medicine at Boston University Medical Center and co-author on the new analysis, told NutraIngredients-USA.com that the most realistic approach to boosting the nation’s intake of vitamin D is for food manufacturers to increase the dose of vitamin D per serving.

      According to Euromonitor, Functional foods, multivitamins and fish oil are an increasing threat to single vitamin D supplements.

      The effects of deficiency

      Vitamin D deficiency in adults is reported to precipitate or exacerbate osteopenia, osteoporosis, muscle weakness, fractures, common cancers, autoimmune diseases, infectious diseases and cardiovascular diseases. There is also some evidence that the vitamin may reduce the incidence of several types of cancer and type-1 diabetes.

      The science supporting the muscle function of vitamin D, as well as the vitamin’s role in immune health, is sufficiently robust to have merited a positive opinion from the European Food Safety Authority’s (EFSA) Panel on Dietetic Products, Nutrition and Allergies (NDA). Despite such proclamations of support, many people across the world are not getting enough vitamin D.

        That's because most kids are lazy punks that are glued to xbox, cellphones, iPods, etc. They don't go outside like we used to. My parents would make us go out and do stuff outside, we would go out in the am and not come in till after dark. Now parents don't give a Sh!t what their kids do (some). They don't have time to be parents, that's what teachers are for lol. I see it everyday kids are so busy burying their noses is itarded devices they can barely pay attention in class. Of course it is against school policy to have these devices, but enforcement is minimal. I guess what I'm saying is ...GO OUT SIDE AND PLAY DAMNIT!!!

        Same here.
        As soon as we got our homework done we had to go outside.
        There were no if ands or buts.
        And if we did have a gaming system we could possibly play for hour or two on saturday and sunday nights depending on how long we had before 9:00 when we came inside.

        It is just trends. Not condoning it but unless the kids have one of those, they will be ostracized and outcast and not many want to deal with that.
        Some people I know bought cellphones for 11 and 12 year olds. IMHO if you have no job and all you do is go to school, maybe extracurriculars, the library and other similar things, why do you need a cellphone.
