What YOU can do about Climate Change with Food

Let's start by quoting Michael Pollan - "Eat food, not too much, mostly plants."  Raising livestock accounts for nearly 15% of global greenhouse gases emitted each year. Some say it's closer to 50%. Cows are the most prolific offenders, generating the potent gas methane as they digest their food. Agricultural land used to grow livestock food is a problem.  In the U.S. and Canada the average per capita consumption of protein is 65 to 90 grams per day, while most adults require 50 grams per day.  This excess protein consumed can be associated with certain cancers, strokes and heart disease. Eating less meat will help you and the planet.  A study from the University of Oxford discussed the economic benefits of a worldwide transition to a plant based diet. Emissions could be reduced 70% through adoption of a vegan diet and 63% through adoption of a vegetarian diet (including cheese, milk and eggs).  Popular author Mark Bittman has written a book called "How to Cook Everything Vegetarian"  Start your own garden if you have the space.  This will ensure that you eat more plants.  Reduce food waste.  A third of food raised or prepared is wasted.  Do not reject food in the market that has minor imperfections. Don't lose track of food in your refrigerator.  Labels saying 'best by' or 'best before' are largely unregulated.  Freeze food that you will not use immediately. If you want fish, buy shell fish such as mussels,  clams or scallops that are designated as green. Consult the Monterey Bay Aquarium for seafood ideas.  Last but not least - support family planning. Fewer unplanned or unwanted pregnancies around the world will make a big difference in global warming.   More on that next week.  Sadja Greenwood, MD, MPH
