Children and vitamin D will be the discussion for the next several decades as we try to discover the true importance of how sunshine interacts with growth and disease states. We have spent the last fifty years figuring out ways to keep children from going into the sun. The sun, we were told is going to be very bad for your skin and will lead to skin cancer if you get burned as a child. We were also told even if you do not burn that too much exposure to sun is not a good thing. We have never been told that low or no exposure to sun is a not good and even a very bad thing because of infections and chronic disease.
Growing up in the fifties and sixties, there were never any of my friends that had trouble with their backs unless they had hurt themselves in some fashion. Spine issues were minor of course except for the few cases of spina bifida or scoliosis. I truly believe that both of these diseases are from the mother being vitamin D deficient in combination with other nutrients like folic acid for spina bfida. Now it is impossible to talk with a teenager that does not know someone their age that has had back surgery. This is just the beginning of a host of chronic diseases for children of the 1980’s, 90’s, 10’s that will result in mass illness of many forms.
To prevent the most of diseases, both chronic and infectious, vitamin D is a necessity. So then the question arises how much vitamin D should we get and how should we maintain a healthy exposure to the sun. Let me first say that exposure to the sun is still a growing science and we do not know all of the biochemical activity that is happening when we expose ourselves to the sun. Our relationship to the sun has changed forever with the development of sunscreens and sun block. Only with a consistent effort to redevelop this relationship will health be achieved. I maintain that the best approach is to just use common sense. The best common sense approach is to maintain a vitamin D level as if it is summer all year round. If you read the medical research while using common sense you will discover that is really what the researchers that are proponents of vitamin D are saying. From your personal perspective you do not get colds in the summertime and the reason is sun exposure. By maintaining your level of vitamin D in the winter time to the summer level you will most likely not get colds then either. I have not had a cold since 2004 when I started this effort.
Babies with colds and congestion?- mothers tell me your experience. I suspect that your child will have significantly less issues if enough vitamin D is made available.
How much vitamin D does it take to achieve this summertime level? From all that I have read a good rule of thumb is to get about 40 IU of D3 from all sources for each pound of body weight. So it does not make any difference if you are a ten pound baby or a two hundred pound senior citizen. For the baby this would give it 400 IU’s per day and for the two hundred pound senior citizen that would be 8000 IU per day. This level of vitamin D intake or production in the skin should maintain your vitamin D level above 60 ng/ml, which is the bottom of the range for vitamin D for person living in a sunny country. Work done by Grant and Holick have shown the 25(OH)D level for sunny country people to be 54 ng/ml to 90 ng/ml.
Of course the only way to know if your serum level of vitamin D is above sixty is to test!
If your total level of intake or production is not 40 IU of D3 per pound of body weight and you do not test to maintain your level above 60 ng/ml then expect disease states. – Pandemic Survivor
