Government urged to raise levels for vital vitamin D
Decades ago, American children faced a dreaded daily routine to prevent rickets and promote overall health: swallowing cod liver oil.
"Before the 1930s, when milk began to be fortified with vitamin D in this country, it was very, very common that children would have been given cod liver oil as a source of vitamin D,” said Allen Knehans, professor of nutritional sciences at the University of Oklahoma Health Sciences Center.
A new study says those doses of cod liver oil can contain detrimental levels of vitamin A. ILLUSTRATION BY LIQUIDLIBRARY.COM

Favored sun
Vitamin D is produced naturally when skin is exposed to sunlight, although people with dark skin cannot produce as much this way. Because of worries over skin cancer, many people have reduced their exposure. A new report by 16 nutrition experts said "... vitamin D deficiency in childhood is now epidemic in Western populations, probably because of the advent of sun exposure protection in the 1980s.”
