Rationing in World War 2 increased intelligence of Britons

A study by the University of Aberdeen and NHS Grampian has found that children who grew up during the Second World War became far more intelligent than those who were born just 15 years before. 

Researchers think that cutting rich, sugary and fatty foods out of the diets of growing children had a hugely beneficial impact on their growing brains. 

Consequently, children born in 1936 grew up to have IQ scores on average 16.5 points ahead of those born in 1921.
