Rugby World Cup - England 2015

As the Rugby World Cup (RWC) kicks off, millions of armchair fans will be scrumming down for six weeks of bone-crunching action.The 20 competing nations have teams of health advisers and nutritionists to ensure they're in peak physical condition for the planet's third largest sporting event.But how can supporters viewing the tournament in their living rooms stay in the best shape and make the right food choices for this television-viewing marathon?Matt Lovell is the England Rugby Union team's nutritionist and we've been looking at how his advice to the players can be incorporated into our RWC-watching habits. Matt's a huge fan of broccoli, as it's packed with detoxifying chemicals and aids liver function. Similar benefits can be gained from brussel sprouts, cabbage and cauliflower. He also says you can tuck into eggs as they're high in protein and B vitamins.Talking of protein sources, chicken and turkey are near the top of Matt's shopping list, though to get the most benefit, it's best to buy free-range and organic. And why not swap those crisps, nuts and sweets for a bowl of blueberries whilst you're engrossed in the on-field action. According to Matt, blueberries are the best fruit for slowing the ageing process as they contain high levels of protective nutrients. And if you're looking for an alternative to fish and chips, why not try wild salmon which is high in essential fats and protein.Making those healthier food choices during the RWC might just make the difference between scoring that try or being tackled just short of the line!
