Eating lettuce could be three times worse for the environment than bacon, scientists have claimed.
Despite calls from celebrities including Arnold Schwarzenegger and Sir Paul McCartney for people to eat less meat to help save the planet, new research suggests that ‘healthier’ diets with more fruit and vegetables could actually be worse for global warming.
The study, by scientists at Carnegie Mellon University, compared the greenhouse gas emissions from the production of 1,000 calories of different foods.
“Eating lettuce is over three times worse in greenhouse gas emissions than eating bacon,” Professor Paul Fischbeck, one of the report’s authors, concluded.
Lettuce is so low in calories that someone would need to eat at least two whole iceberg lettuces to get close to the calorie intake of two rashers of smoked back bacon.
So, what more proof do you need?
