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.
However, a report issued this month by 16 experts said cod liver oil is not a good source of vital vitamin D because the oil also includes toxic levels of vitamin A.

“Americans continue to consume multivitamins and/or cod liver oil containing disproportionately small amounts of vitamin D but detrimental quantities of vitamin A,” the experts said in the report in the Annals of Otology, Rhinology & Laryngology. The high level of vitamin A in cod liver oil “will mask the benefit of adequate vitamin D nutrition,” it said.

Knehans, who was not involved in creating the report, said vitamin A is “clearly toxic” and that high doses over a long period could result in blurred vision, stupor, even coma. “It can be pretty serious.”

The report lauded many apparent benefits of vitamin D, from reduction of influenza and respiratory infections to increased immunity and even prevention of cancer, diabetes and chronic diseases. It also warned of dangers of vitamin D deficiency, including autism, asthma and autoimmune diabetes.

Diet alone cannot solve the problem, the scientists said.

They also said many multivitamins contain far too much vitamin A and far too little vitamin D. They called on federal officials to boost the recommended levels of vitamin D, saying “current official guidelines and limitations for vitamin D intakes are scientifically indefensible.”

Federal guidelines urge people to have a daily vitamin D intake of 200 IU for infants to 600 IU for those 71 and older.

Nature Cures says Hippocrates, and not without a reason, because humankind had become older and healthier, due, in first place, to an education in nutrition, a healthy nutrition education become more and more relevant in health, with civilization and development. We are what we eat and in the same way we react to external invasion to our bodies with the immune system we built. We are completely sure that you will agree with us when we say, that we should treat each cells of our body with the honor they deserve if we want to have a healthy, productive and happy life
