The diet of a professional footballer has changed a lot over the years. No longer are they fuelled by oranges at half-time and no longer will you expect to see “a bottle of brandy or whisky to be in the dressing room, either to settle the nerves or to warm up the players,” to quote the Daily Mail.
Instead, many teams embrace the dietary revolution that was arguably started by Dr Robert Haas' influential book Eat to Win. A revolution that was later pioneered in England by individuals such as Arsene Wenger in 1996, according to Arsenal’s website.
But among the scientifically supported diets and sports supplements there are also some less conventional nutritional protocols. From surprisingly good home remedies prescribed by the Italian legend Dino Zoff’s grandparents, to the shocking prenatal nutrition of Cristiano Ronaldo.
But just how much do players' food choices affect their performances, and would all great players still be as good if they were fueled by a dietitian's nightmare? Here we look at the research surrounding the five strangest diets in football to decide nutrition's impact on the game.
