General recommendations:
The vitamin D levels should be kept at normal range (30 ng/mL) either by vitamin D supplementation or by optimum sun exposure. Sun exposure should be preferred due to its benefits on other physiological functions.
Men, women and children should be encouraged and facilitated to expose themselves in the sun shine. Balanced diet containing dairy products fortified with vitamin D and the use of sea foods should be recommended for child bearing and nursing mothers.
A country wide survey could be conducted to assess the present status of vitamin D in this population and the possible reasons of its deficiency in this population.
