Low Vit D Levels in Children

http://www.eurekalert.org/pub_releas...-lvd070507.php

Public release date: 9-Jul-2007

Low vitamin D levels may be common in otherwise healthy children

Many otherwise healthy children and adolescents have low vitamin D levels, which may put them at risk for bone diseases such as rickets. African American children, children above age nine and with low dietary vitamin D intake were the most likely to have low levels of vitamin D in their blood, according to researchers from The Children’s Hospital of Philadelphia.
A study in the current issue of the American Journal of Clinical Nutrition measured blood levels of vitamin D in 382 healthy children between six years and 21 years of age living in the northeastern U.S. Researchers assessed dietary and supplemental vitamin D intake, as well as body mass, and found that more than half of the children had low blood levels of vitamin D. Of the subjects, 55 percent of the children had inadequate vitamin D blood levels and 68 percent overall had low blood levels of the vitamin in the wintertime.
“The best indicator of a person’s vitamin D status is the blood level of a vitamin D compound called 25-hydroxyvitamin D,” said Babette Zemel, Ph.D., a nutritional anthropologist at Children’s Hospital and primary investigator of this study. “Vitamin D deficiency remains an under-recognized problem overall, and is not well studied in children.”
Vitamin D is crucial for musculoskeletal health. The primary dietary source of the vitamin is fortified milk, but the best way to increase vitamin D levels is from exposure to sunshine. Severe deficits in vitamin D may lead to muscle weakness, defective bone mineralization and rickets. In addition to musculoskeletal effects, vitamin D is important for immune function, and low blood levels of the vitamin may contribute to diseases such as hypertension, cancer, multiple sclerosis and type 1 diabetes. Decreased blood levels of vitamin D have also been linked to obesity.
Further study is needed to determine the appropriate blood levels of vitamin D in children, said Dr. Zemel, who added that a review of the current recommendations for vitamin D intake is needed.

Easy ways to Improve skin's natural sunscreen ability.

Each of these research based suggestions will improve the time you and your children can safely stay out in the sun without your skin going pink.
  1. Improve Vitamin D status with Cholecalciferol Supplements, Vitamin D3 is part of the skin's photoprotection mechanism. By building up Vit d reserves before sun exposure you will tan naturally quicker and so this will also add to the skin's protection. I've already got a good suntan this year just by keeping my Vit d up in the Winter, just going outside a few times and I'm starting to tan nicely.
  2. Improve omega 3 status. EPA the omega 3 essential fatty acid found in fish oil or metabolised from ground Flaxseed (or flaxseed oil) if your veggie will also improve the skin's photoprotection properties. If you can't consume it, massage it into the skin, that will take it up and improve the UVR resistance.
  3. 2 tbspoons tomato puree + 2tsps olive oil daily per person will lengthen the time it takes for skin to burn. See Tomatoes and Skin Protection What you are adding is the lycopene in tomatoes and polyphenols in olive oil are both phytonutrients.
  4. Drink Green tea. If you can't be persuades to drink it hot then make it half strength put it in the fridge to get really cold then top it up with fizzy bottled water maybe add some honey. Green tea can also be applied directly to the skin or you can wash/bath in it.
  5. Pomegranate juice, another high phytonutrient with strong antioxidant and anti-inflammatory properties.
  6. Make sure you have plenty of other phytonutrients in your diet. ie raspberries, blueberries, World's Healthiest Foods Highest in Antioxidant
  7. PhytonutrientsSystemic photoprotection through carotenoids
  8. Nutritional supplements are increasingly used to protect human skin against environmentally-induced damage, most importantly as a consequence of ultraviolet radiation exposure. beta-carotene is a major constituent of comercially available products administered for systemic photoprotection. Studies on the systemic use of beta-carotene provide evidence that 15-30 mg/d over a period of about 10-12 wk produces a protective effect against UV-induced erythema. Beta Carotene Food Sources
  9. Improve the antioxidant factors in diet, selenium, vitamin C, Vitamin E have a good evidence to support their use but use natural food sources rather than synthetic.
  10. Build up exposure to UVB now gradually, by regular, limited, exposure to UVR. A home solaria sunlamp used perhaps 3 times a week through the winter for just a few minutes each time will harden the skin and enable it to cope with sunlight during the Summer without burning. UV hardening therapy:
  11. Read this page of The Vitamin D Council newsletter You can find the cheapest high strength Vitamin D from the links page on that site.
  12. How can my diet help protect me from sunburn?: answer
A further suggestion that I don't, at present, have any scientific research to back up, is when outside early in the morning to allow some time to allow some time when you do not wear sunglasses or tinted spectacles. The tanning process is controlled by the melatonin cycle, this is regulated by the amount of light that goes through your eyes. Reducing the amount of light entering your eyes means your melatonin won't be regulated properly. If your brain doesn't think it's bright enough for the skin to be damaging your skin it won't start the process to start tanning.
Be aware that 6 out of ten of UK residents remains Vitamin d insufficient throughout the Summer leaving them vulnerable to cancers, diabetes, obesity, heart disease, hypertension, Osteoporosis, osteoarthritis, Mental illness, depression, Multiple Sclerosis and more, for each individual dying from cancers arising from excessive sunburn, 30 will die from cancers thriving in Vitamin D depleted bodies and a total of 250 die from conditions arising from too low a vitamin D status. Regular limited direct exposure to sunshine is far more important than complete protection. There is absolutely no point in striving so hard to prevent skin cancer that you actually promote prostate, breast and colon cancer. These are far greater risks and avoiding all sun exposure more than doubles the risk you put you child in. You really must not, while in the UK put sunscreen on before your child goes outdoors. That is inviting those risk factors thought to lead to Multiple Sclerosis and the above most common deadly cancers by denying the natural protection afforded by high vitamin d status. There is no point at all in avoiding skin cancer if in doing so your deliberately, knowingly double the risk of breast, prostate, colon cancers and MS.

You have to be aware that Vitamin D protects more than sunburn damages so the research shows even people with active melanomas (the most deadly skin cancer) have BETTER LONGER prognosis if they CONTINUE to SUNBATHE.

The aim of sunblock is to prevent burning, but if you apply it before you go outside and never allow your skin to react in the way it naturally evolved and so by preventing Vitamin D production YOU ARE DOING MORE HARM THAN GOOD.

I had Polio as a child in the 1950's and now have the Late Effects of Polio
I got to the point a few years back of needing a scooter to go out anywhere and permanent wheelchair use seemed to be looming so I was getting really alarmed at the prospect of being unable to look after myself or get about on my own. In an effort to find a solution to the year on year progressive decline in physical performance I found this paper by Marcia Falconer on Inflammation and PPS

From there I thought how can I improve my natural anti inflammatory potential. I started by improving my PUFA (omega 3) intake to over 4g epa+dha daily but that didn't seem to do much, it was only when I discovered the link between "Vitamin D and Inflammation" that my health started to improve.

Obviously no amount of vitamin D is going to repair the damage already inflicted by the polio virus or the overuse of previously damaged muscles but it does help make the best of a bad job and because Vitamin d is the Antibiotic vitamin I now don't get Colds or flu

Because it's made such a huge difference to my health being Vitamin D replete I feel more people should know about it.
You folks who use sunbeds will know how regular sunbed use (providing the tubes give out a reasonable amount of UVB) will know how having a high vitamin D status improves your feelings of Well being and actual muscular physical athletic performance but I don't think most people understand. Which I why (as I can't do much else) I do feel it's important to ensure people know about Vitamin D, about safe sun exposure and how best to ensure they get a high vitamin D status without getting sun-burnt and increasing their risk of skin cancer.

I'm sure all this is well known to readers here but as it is so important children get sun exposure and DON'T get burnt I felt a few words about how this can best be achieved wouldn't go amiss.

Laying down for 5 minutes full body sun exposure when your shadow is shorter than your height should raise 1000iu/vitamin D3 turning over to give the other side a go doubles that amount and repeating the process will ensure your Daily Vitamin D3 requirement is met.

There is a simple animated diagram of how UVB converts cholesterol into vitamin d3 here scrolling down to the next animation shows what happens to that newly made Vitamin d if you continue to apply heat to it. So rather than stay out in the sun (or under the lamps) too long it is far better to allow your skin to cool off, the Vitamin D3 to be absorbed and a further session later in the day will boost your levels for the Winter or rectify an insufficiency situation.

Excellent post Ted. Have you done any research on Curcumin? It's the one thing I don't see mentioned that you might want to add to your diet on a daily basis. :)

Re: Low Vit D Levels in Children

UK readers should not think Children with low vitamin D status is simply a USA situation.

UK Adult population are 90% Vitamin D insufficient in Winter and 60% remain so throughout the Summer.

and for Teenage girls the situation is much the same. The way many children are not encouraged to play outside and are smothered with sunscreen before they ever leave the house means the situation is no different here and given we live further from the Equator it's probably worse.

But the latest findings, that the ideal minimum status should really be 100nmol/L, show that even more people than these reports regard as having below par vitamin D status, should be paying attention to ways of regularly getting UVB exposure. Your skin is an endocrine organ and as such should have regular opportunity to act as evolution deemed desirable.

Re: Low Vit D Levels in Children

Thanks for your posts, Ted, excellent.

We have a customer with polio who was getting worse every year. By regularly excercising (we have a fitness center) he slowed the process down, at least so much that the doctors were amazed. Now I'll run and get him this info, and I hope that it will do him more good!

I've talked with my customer about it and he's very interested. I'll keep you all up to date if it changes anything for him.

Re: Low Vit D Levels in Children

I'm sure you are aware that having an optimal vitamin D status (such as one would have if you regularly spent time naked outdoors as we evolved and as in the Garden of Eden) achieves peak physical performance and Why Athletic Performance Matters particularly for seniors.

It is particularly important for those with the Late Effects of Polio to be aware not only of the importance of being as fit as possible (to make the best of a bad job) but also of the need to pace activities so as not to overdo it and cause more inflammation and further damage.
