A diet has been developed that promises to save lives, feed 10 billion people and all without causing catastrophic damage to the planet. Scientists have been trying to figure out how we are going to feed billions more people in the decades to come. Their answer – “the planetary health diet” – does not completely banish meat and dairy. But it is recommending we get most of our protein from nuts and legumes such as beans and lentils instead. Their diet needs an enormous shift in what we pile on to our plates and for us to turn to foods that we barely eat. If you eat meat every day then this is the first biggie. For red meat you’re looking at a burger a week or a large steak a month and that’s your lot.
Adopting more plant-based diets for ourselves could reduce the greenhouse gas emissions of the food system by more than half, according to the Nature study. Hide Caption. How to eat well – and save the planet.
And there are “knock-on carbon benefits” that come along with not having to transport, process, retail, package and refrigerate all this extra food, according to an emailed statement by Eugene Mohareb, a lecturer in sustainable urban systems at the University of Reading in the UK. We can no longer feed our population a healthy diet while balancing planetary resources. These are now the biggest killers in developed countries. We’re not talking about a deprivation diet here, it is healthy eating that is flexible and enjoyable. But it is recommending we get most of our protein from nuts and legumes such as beans and lentils instead. Topics Food. Prof Walter Willet, one of the researchers who is based at Harvard, said no and that after a childhood on a farm eating three portions of red meat a day he was now pretty much in line with the planetary health diet. The researchers’ aim was to feed more people while. Companies Show more Companies. Lisa Drayer is a nutritionist, an author and a CNN health and nutrition contributor.
Citizens will be healthier and their food can be produced using less of one of our most precious natural resources – water. Freshwater resources are already scarce, but the problem is set to get worse, due to population growth, changing lifestyles and climate change. Public messages on saving water by taking shorter showers or turning off the tap when brushing teeth are well known. But there is lower awareness of the amount of water used to produce food. Raising livestock uses up a lot of water. Oils, sugars and fats also require large amounts of water to produce, but growing fruits and vegetables is more water efficient. It is based on analysis of food-related water consumption for current and recommended diets healthy diet with meat, healthy pescetarian diet and healthy vegetarian diet down to the level of individual boroughs, in the most detailed study of its kind. The authors acknowledge that encouraging people to change their diet is not straightforward and requires a number of interventions, from taxing unhealthy food to better food labelling.
