Nutrition science is looking decidedly dodgy these days. One reason is the love affair with vitamins, a century after scientists discovered them.
That affair has spawned the billion-dollar global supplement industry. It has also created “pseudo-diseases” in its wake, says British geneticist Prof Tim Spector. One of those pseudo-diseases is Vitamin D deficiency.
Spector is professor of genetic epidemiology and director of the TwinsUK Registry, at Kings College London. Spector has looked at another confounding variable in nutrition research these days: We have ignored a new “virtual” organ in our bodies for the digestive and endocrine system, he says. It is the microbiome that he calls our “second brain”.
