Give any 2 reasons why young school-age children today may have lower vitamin D levels than children 30-40 years ago
Many young children do not play outside as much as children did in the past. They tend to watch more TV or play video games indoors. This reduces their exposure to the sun and so their skin makes far less vitamin D precursor.
Many young children do not drink as much milk. This could due to a variety of factors: (1) Milk is more expensive than in the past, so children may drink more soda or sweetened drinks in place of milk. (2) Many children may be lactose intolerant and do not eat or drink foods that are good sources of vitamin D.
