Kids’ Bones at Risk From Low Vitamin D
http://children.webmd.com/news/20070709/kids-bones-at-risk-from-low-vitamin-d
The article states that it is the result of kids not drinking enough milk, drinking soda pop instead. Everyone I knew as a kid drank whole milk and no one was fat. Soda pop and ding dongs will make you fat, not 3 glasses of whole milk a day.
The Vitamin D deficiencies are more of a result of those screaming that we must stay out of the sun. People have become so afraid of sun exposure that they’ve forgotten the sun can be good for you. Safe exposure to it gives you all the Vitamin D you need.
As for us, we’ll always drink Whole Milk. I’m trying to go more natural and cut processed foods out of our life. With the exception of getting raw milk from a farmer, organic whole milk is the most natural, least processed you can get in the stores.
And not enough playing outside.
Sun exposure is a more efficient way to get Vitamin D than milk, but with all of the sunscreen use, that is leading to Vitamin D deficiency. I predict that there will eventually be a “policy” warning against too much sunscreen (in a couple of years).
