It seems that sedentary lifestyle, poor diet and lack of exposure to sunlight is taking its toll on the last generation of Britons: rickets are on the rise again, causing a debate on whether to implement laws forcing food companies to supplement their products with vitamin D. Ol' good cod liver oil is also being missed.
According to Times Online, some 50% of British adults have vitamin D deficiency in winter and spring, one of six severely so. People of "Asian" origin and in particular those who cover much of their body because of religious reasons (read: Muslims particularly) are at increased risk.
The article also blames television and videogames for this epidemic.
