Anna Raeburn recalls that in the 1970s, a disease called kwashiorkor was prevalent in Biafra. 'All the children were malnourished, because they weren't getting any protein, but their mothers didn't realise that was the problem, and they couldn't have got hold of protein anyway, so they kept feeding them starch. The children remained stick-thin and hopelessly malnourished, but with distended bellies. Modern life is like that: we keep feeding ourselves the wrong things for happiness.
